166-441: Wagyu ( Japanese : 和牛 , Hepburn : wagyū , lit. ' Japanese cattle ' ) is the collective name for the four principal Japanese breeds of beef cattle . All wagyū cattle originate from early twentieth-century cross-breeding between native Japanese cattle and imported stock, mostly from Europe. Wagyu beef is among the most expensive meats in the world. It features marbling , meaning that streaks of fat exist within
332-624: A benefit from the in-group to the out-group) means "[I/we] explained [it] to [him/her/them]". Such beneficiary auxiliary verbs thus serve a function comparable to that of pronouns and prepositions in Indo-European languages to indicate the actor and the recipient of an action. Japanese "pronouns" also function differently from most modern Indo-European pronouns (and more like nouns) in that they can take modifiers as any other noun may. For instance, one does not say in English: The amazed he ran down

The Japanese writing system combines Chinese characters , known as kanji ( 漢字 , ' Han characters') , with two unique syllabaries (or moraic scripts) derived by the Japanese from the more complex Chinese characters: hiragana ( ひらがな or 平仮名 , 'simple characters') and katakana ( カタカナ or 片仮名 , 'partial characters'). Latin script ( rōmaji ローマ字 )
830-786: A date of around 40 AD (±90 years). However, some in the Japanese archaeological community remain skeptical about the presence of cattle in Japan during the Yayoi period, and there is a persistent view that they were brought to Japan from the Korean peninsula by the toraijin , a group of people who came to Japan in the mid-5th century during the Kofun period . At the Nango-Ōhigashi site in Gose City , Nara Prefecture , excavations revealed cow bones believed to date back to

It was revised again in the early 1960s to 5,730 ± 40 years, which meant that many calculated dates in papers published prior to this were incorrect (the error in the half-life is about 3%). For consistency with these early papers, it was agreed at the 1962 Radiocarbon Conference in Cambridge (UK) to use the "Libby half-life" of 5568 years. Radiocarbon ages are still calculated using this half-life, and are known as "Conventional Radiocarbon Age". Since
1162-414: A distinct language of its own that has absorbed various aspects from neighboring languages. Japanese has five vowels, and vowel length is phonemic, with each having both a short and a long version. Elongated vowels are usually denoted with a line over the vowel (a macron ) in rōmaji , a repeated vowel character in hiragana , or a chōonpu succeeding the vowel in katakana . /u/ ( listen )

Water in the deep ocean takes about 1,000 years to circulate back through surface waters, and so the surface waters contain a combination of older water, with depleted C , and water recently at the surface, with C in equilibrium with the atmosphere. Creatures living at
1494-442: A fragment of bone, provides information that can be used to calculate when the animal or plant died. The older a sample is, the less C there is to be detected, and because the half-life of C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to approximately 50,000 years ago (in this interval about 99.8% of
1660-408: A given sample stopped exchanging carbon – the older the sample, the less C will be left. The equation governing the decay of a radioactive isotope is: N = N 0 e − λ t {\displaystyle N=N_{0}\,e^{-\lambda t}\,} where N 0 is the number of atoms of the isotope in the original sample (at time t = 0, when

The Yoro Code also includes provisions for the sale of the hides and meat of horses and cattle, and there were distribution channels throughout Japan for buying and selling these items during the Nara period. During

The animal's own biochemical processes can also impact the results: for example, both bone minerals and bone collagen typically have a higher concentration of C than is found in the animal's diet, though for different biochemical reasons. The enrichment of bone C also implies that excreted material
2324-479: A listener depending on the listener's relative social position and the degree of familiarity between the speaker and the listener. When used in different social relationships, the same word may have positive (intimate or respectful) or negative (distant or disrespectful) connotations. Japanese often use titles of the person referred to where pronouns would be used in English. For example, when speaking to one's teacher, it

Accumulated dead organic matter, of both plants and animals, exceeds the mass of the biosphere by a factor of nearly 3, and since this matter is no longer exchanging carbon with its environment, it has a C / C ratio lower than that of the biosphere. The variation in the C / C ratio in different parts of
2656-854: A paper in Science in 1947, in which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin. Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages. For example, two samples taken from the tombs of two Egyptian kings, Zoser and Sneferu , independently dated to 2625 BC plus or minus 75 years, were dated by radiocarbon measurement to an average of 2800 BC plus or minus 250 years. These results were published in Science in December 1949. Within 11 years of their announcement, more than 20 radiocarbon dating laboratories had been set up worldwide. In 1960, Libby

The Uruguay Round of the General Agreement on Tariffs and Trade (GATT) from 1986 to 1994, which set rules for liberalization of international trade, decided to liberalize imports of foreign beef to Japan. Beef imports have been liberalized since 1991. In FY1993, beef imports jumped 34% over
2988-534: A result, from around 1907, there were no more crossbreds being bred, and in reaction, the old black cattle were considered good, and as long as they were small and black, they could be sold. As crossbreeding with Western breeds progressed, the term "pure Wagyu" ( 純粋和牛 , junsui Wagyū ) emerged to describe native Japanese cattle, and by 1912, it was claimed that there were two definitions of Wagyu: "pure Wagyu" and "improved Wagyu" ( 改良和牛 , kairyō Wagyū ). At that time, Mendel's laws had just been rediscovered, and both
3154-629: A sample. More recently, accelerator mass spectrometry has become the method of choice; it counts all the C atoms in the sample and not just the few that happen to decay during the measurements; it can therefore be used with much smaller samples (as small as individual plant seeds), and gives results much more quickly. The development of radiocarbon dating has had a profound impact on archaeology . In addition to permitting more accurate dating within archaeological sites than previous methods, it allows comparison of dates of events across great distances. Histories of archaeology often refer to its impact as
3320-408: A sentence need not be stated and pronouns may be omitted if they can be inferred from context. In the example above, hana ga nagai would mean "[their] noses are long", while nagai by itself would mean "[they] are long." A single verb can be a complete sentence: Yatta! ( やった! ) "[I / we / they / etc] did [it]!". In addition, since adjectives can form the predicate in a Japanese sentence (below),
3486-428: A single adjective can be a complete sentence: Urayamashii! ( 羨ましい! ) "[I'm] jealous [about it]!". While the language has some words that are typically translated as pronouns, these are not used as frequently as pronouns in some Indo-European languages, and function differently. In some cases, Japanese relies on special verb forms and auxiliary verbs to indicate the direction of benefit of an action: "down" to indicate

Cattle were highly prized and valuable, too expensive for a poor farmer to buy. Japan was effectively isolated from the rest of the world from 1635 until 1854; there was no possibility of the intromission of foreign genes to the cattle population during this time. In western Japan during

At the same time, however, it was also believed that Wagyu were superior to Western breeds for plowing use but inferior in milk and meat production, and their improvement
3984-624: Is compressed rather than protruded , or simply unrounded. Some Japanese consonants have several allophones , which may give the impression of a larger inventory of sounds. However, some of these allophones have since become phonemic. For example, in the Japanese language up to and including the first half of the 20th century, the phonemic sequence /ti/ was palatalized and realized phonetically as [tɕi] , approximately chi ( listen ) ; however, now [ti] and [tɕi] are distinct, as evidenced by words like tī [tiː] "Western-style tea" and chii [tɕii] "social status". The "r" of

The method was developed in the late 1940s at the University of Chicago by Willard Libby , based on the constant creation of radiocarbon ( C ) in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen . The resulting C combines with atmospheric oxygen to form radioactive carbon dioxide , which

The different elements of the carbon exchange reservoir vary in how much carbon they store, and in how long it takes for the C generated by cosmic rays to fully mix with them. This affects the ratio of C to C in the different reservoirs, and hence the radiocarbon ages of samples that originated in each reservoir. The atmosphere, which

Late Middle Japanese has the first loanwords from European languages – now-common words borrowed into Japanese in this period include pan ("bread") and tabako ("tobacco", now "cigarette"), both from Portuguese . Modern Japanese is considered to begin with the Edo period (which spanned from 1603 to 1867). Since Old Japanese,

Word order is normally subject–object–verb with particles marking the grammatical function of words, and sentence structure is topic–comment . Sentence-final particles are used to add emotional or emphatic impact, or form questions. Nouns have no grammatical number or gender , and there are no articles . Verbs are conjugated , primarily for tense and voice , but not person . Japanese adjectives are also conjugated. Japanese has

This is because anata is used to refer to people of equal or lower status, and one's teacher has higher status. Japanese nouns have no grammatical number, gender or article aspect. The noun hon ( 本 ) may refer to a single book or several books; hito ( 人 ) can mean "person" or "people", and ki ( 木 ) can be "tree" or "trees". Where number

The Ryūkyūan languages, spoken in Okinawa and the Amami Islands (administratively part of Kagoshima ), are distinct enough to be considered a separate branch of the Japonic family; not only is each language unintelligible to Japanese speakers, but most are unintelligible to those who speak other Ryūkyūan languages. However, in contrast to linguists, many ordinary Japanese people tend to consider

If the carbon in freshwater is partly acquired from aged carbon, such as rocks, then the result will be a reduction in the C / C ratio in the water. For example, rivers that pass over limestone , which

Under these conditions, fractionation is reduced, and at temperatures above 14 °C (57 °F) the δ C values are correspondingly higher, while at lower temperatures, CO 2 becomes more soluble and hence more available to marine organisms. The δ C value for animals depends on their diet. An animal that eats food with high δ C values will have

Today, Wagyu refers to four breeds known as "improved Wagyu" ( 改良和牛 , kairyō wagyū ), which have been established as distinct breeds through crossbreeding with European cattle. The rich marbling that is considered a characteristic of Wagyu is actually a feature of the Japanese Black breed, and not of the other three breeds.

Volcanic eruptions eject large amounts of carbon into the air.

There have been many attempts to group the Japonic languages with other families such as the Ainu , Austronesian , Koreanic , and the now-discredited Altaic , but none of these proposals have gained any widespread acceptance. Little
12284-680: The steppe bison (Bison priscus) lineage. Fossil bones of Aurochs (Bos primigenius) have also been found in Ichinoseki City. Since Hokkaido and Honshu were land-locked with the Eurasian continent during the Ice Age, these animals came from the continent via Hokkaido. In addition, projectile points made from polished wild cattle bones have been found at the same site, although in small quantities, suggesting that humans existed during this period and that Hanaizumi Moriushi and aurochs were hunted. At
12450-659: The "radiocarbon revolution". Radiocarbon dating has allowed key transitions in prehistory to be dated, such as the end of the last ice age , and the beginning of the Neolithic and Bronze Age in different regions. In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research. They synthesized C using
12616-518: The 1.2 million of the United States ) sometimes employ Japanese as their primary language. Approximately 12% of Hawaii residents speak Japanese, with an estimated 12.6% of the population of Japanese ancestry in 2008. Japanese emigrants can also be found in Peru , Argentina , Australia (especially in the eastern states), Canada (especially in Vancouver , where 1.4% of the population has Japanese ancestry),
12782-680: The 5th century. At the Funamiya Kofun Tumulus (late 5th century) in Asago City , Hyōgo Prefecture , pieces of a cow-shaped haniwa (clay figurine), believed to be the oldest in Japan, have been excavated. In addition, a cow-shaped haniwa was excavated from the Hashida No. 1 Tumulus in Tawaramoto Town , Shiki-gun , Nara Prefecture in the first half of the 6th century, and was designated as an Important Cultural Property of Japan in 1958. On
12948-463: The Japanese government and cattle farmers lacked sufficient knowledge of genetics. The unpopularity of crossbred cattle led to the Japanese government's decision in 1911 to suspend plans to purchase Brown Swiss and Simmental cattle. In 1912, the Japanese government decided to formally end its policy of encouraging crossbreeding by announcing that crossbreeding between Wagyu and European breeds had been sufficiently successful. From then on, Wagyu improvement
13114-482: The Japanese language is of particular interest, ranging between an apical central tap and a lateral approximant . The "g" is also notable; unless it starts a sentence, it may be pronounced [ ŋ ] , in the Kanto prestige dialect and in other eastern dialects. The phonotactics of Japanese are relatively simple. The syllable structure is (C)(G)V(C), that is, a core vowel surrounded by an optional onset consonant,
13280-634: The Ohama Site in Goto City , Nagasaki Prefecture , cattle teeth dating to the middle Yayoi period were excavated. Among them were also processed cattle molars. However, this excavation was controversial because it contradicted the statement in Chen Shou 's Records of the Three Kingdoms ( Wajinden ) that there were no cattle or horses in Japan. Later, radiocarbon dating of the excavated cattle molars yielded
13446-724: The Old Japanese sections are written in Man'yōgana , which uses kanji for their phonetic as well as semantic values. Based on the Man'yōgana system, Old Japanese can be reconstructed as having 88 distinct morae . Texts written with Man'yōgana use two different sets of kanji for each of the morae now pronounced き (ki), ひ (hi), み (mi), け (ke), へ (he), め (me), こ (ko), そ (so), と (to), の (no), も (mo), よ (yo) and ろ (ro). (The Kojiki has 88, but all later texts have 87. The distinction between mo 1 and mo 2 apparently
13612-488: The Ryūkyūan languages as dialects of Japanese. The imperial court also seems to have spoken an unusual variant of the Japanese of the time, most likely the spoken form of Classical Japanese , a writing style that was prevalent during the Heian period , but began to decline during the late Meiji period . The Ryūkyūan languages are classified by UNESCO as 'endangered', as young people mostly use Japanese and cannot understand
13778-469: The Takenotani tsuru has been attracting attention in recent years. In 1859, Japan opened the port of Yokohama in accordance with the demands of Western nations. At the same time, a foreign settlement was established in Yokohama . Foreign residents sought cattle for meat from neighboring villages but were refused, so cattle were imported from the U.S., China, and Korea, which gradually became unable to meet
13944-399: The above-ground nuclear tests performed in the 1950s and 1960s. Because the time it takes to convert biological materials to fossil fuels is substantially longer than the time it takes for its C to decay below detectable levels, fossil fuels contain almost no C . As a result, beginning in the late 19th century, there was a noticeable drop in the proportion of C in
14110-399: The actual calendar date, both because it uses the wrong value for the half-life of C , and because no correction (calibration) has been applied for the historical variation of C in the atmosphere over time. Carbon is distributed throughout the atmosphere, the biosphere, and the oceans; these are referred to collectively as the carbon exchange reservoir, and each component
14276-543: The addition of a collective suffix (a noun suffix that indicates a group), such as -tachi , but this is not a true plural: the meaning is closer to the English phrase "and company". A group described as Tanaka-san-tachi may include people not named Tanaka. Some Japanese nouns are effectively plural, such as hitobito "people" and wareware "we/us", while the word tomodachi "friend" is considered singular, although plural in form. Verbs are conjugated to show tenses, of which there are two: past and present (or non-past) which
14442-418: The appropriate correction for the location of their samples. The effect also applies to marine organisms such as shells, and marine mammals such as whales and seals, which have radiocarbon ages that appear to be hundreds of years old. The northern and southern hemispheres have atmospheric circulation systems that are sufficiently independent of each other that there is a noticeable time lag in mixing between
14608-457: The atmosphere as the carbon dioxide generated from burning fossil fuels began to accumulate. Conversely, nuclear testing increased the amount of C in the atmosphere, which reached a maximum in about 1965 of almost double the amount present in the atmosphere prior to nuclear testing. Measurement of radiocarbon was originally done with beta-counting devices, which counted the amount of beta radiation emitted by decaying C atoms in
14774-438: The atmosphere might be expected to decrease over thousands of years, but C is constantly being produced in the lower stratosphere and upper troposphere , primarily by galactic cosmic rays , and to a lesser degree by solar cosmic rays. These cosmic rays generate neutrons as they travel through the atmosphere which can strike nitrogen-14 ( N ) atoms and turn them into C . The following nuclear reaction
14940-547: The atmosphere, is dissolved in the ocean, and is taken up by plants via photosynthesis . Animals eat the plants, and ultimately the radiocarbon is distributed throughout the biosphere . The ratio of C to C is approximately 1.25 parts of C to 10 parts of C . In addition, about 1% of the carbon atoms are of the stable isotope C . The equation for the radioactive decay of C is: 6 C → 7 N + e + ν e By emitting
15106-421: The atmospheric C / C ratio has not changed over time. Calculating radiocarbon ages also requires the value of the half-life for C . In Libby's 1949 paper he used a value of 5720 ± 47 years, based on research by Engelkemeir et al. This was remarkably close to the modern value, but shortly afterwards the accepted value was revised to 5568 ± 30 years, and this value was in use for more than
15272-425: The biosphere, gives an apparent age of about 400 years for ocean surface water. Libby's original exchange reservoir hypothesis assumed that the C / C ratio in the exchange reservoir is constant all over the world, but it has since been discovered that there are several causes of variation in the ratio across the reservoir. The CO 2 in the atmosphere transfers to the ocean by dissolving in
15438-450: The calibration curve (IntCal) also reports past atmospheric C concentration using this conventional age, any conventional ages calibrated against the IntCal curve will produce a correct calibrated age. When a date is quoted, the reader should be aware that if it is an uncalibrated date (a term used for dates given in radiocarbon years) it may differ substantially from the best estimate of
15604-435: The carbon exchange reservoir means that a straightforward calculation of the age of a sample based on the amount of C it contains will often give an incorrect result. There are several other possible sources of error that need to be considered. The errors are of four general types: In the early years of using the technique, it was understood that it depended on the atmospheric C / C ratio having remained
15770-500: The carbon exchange reservoir, but because of the long delay in mixing with the deep ocean, the actual effect is a 3% reduction. A much larger effect comes from above-ground nuclear testing, which released large numbers of neutrons into the atmosphere, resulting in the creation of C . From about 1950 until 1963, when atmospheric nuclear testing was banned , it is estimated that several tonnes of C were created. If all this extra C had immediately been spread across
15936-432: The central organization for the registration of cattle throughout Japan, the breed names of " Japanese Black ," " Japanese Polled ," and " Japanese Brown " were created in place of the above nine breeds. In 1944, it was officially decided to abolish the conventional name "Improved Japanese Breed" and call the breeds Japanese Black, Japanese Brown, and Japanese Polled, as the characteristics of each breed had been clarified as
16102-435: The date of the sample. Samples for dating need to be converted into a form suitable for measuring the C content; this can mean conversion to gaseous, liquid, or solid form, depending on the measurement technique to be used. Before this can be done, the sample must be treated to remove any contamination and any unwanted constituents. This includes removing visible contaminants, such as rootlets that may have penetrated
16268-665: The demand. In 1865, before the Port of Kobe was opened, the Hyogo Port Opening Demand Incident occurred, in which nine warships from Britain, France, the Netherlands, and the United States invaded Hyogo Port demanding its opening. At that time, sailors negotiated with local cattle merchants for cattle, which were initially slaughtered on board, but as demand increased, it became necessary to slaughter them on land. 1866 saw
16434-552: The dorsal line), white spots, etc. On the other hand, efforts were made to improve the physique and weight of both pure and improved Wagyu cattle, and from around the 1920s, the term "improved Wagyu" came to refer to all Wagyu cattle, including not only improved Wagyu but also pure Wagyu. Around 1919, the examination and registration of Wagyu began mainly in western Japan, and pedigrees and body types began to be registered. Nine breeds were registered: Tajima, Bisaku, Hiroshima, Bocho, Shimane, Inhaku, Bungo, Kumamoto, and Kagoshima. However,
16600-490: The early 20th century hence gives an apparent date older than the true date. For the same reason, C concentrations in the neighbourhood of large cities are lower than the atmospheric average. This fossil fuel effect (also known as the Suess effect, after Hans Suess, who first reported it in 1955) would only amount to a reduction of 0.2% in C activity if the additional carbon from fossil fuels were distributed throughout
16766-513: The effect of changing Japanese into a mora-timed language. Late Middle Japanese covers the years from 1185 to 1600, and is normally divided into two sections, roughly equivalent to the Kamakura period and the Muromachi period , respectively. The later forms of Late Middle Japanese are the first to be described by non-native sources, in this case the Jesuit and Franciscan missionaries; and thus there
16932-401: The entire carbon exchange reservoir, it would have led to an increase in the C / C ratio of only a few per cent, but the immediate effect was to almost double the amount of C in the atmosphere, with the peak level occurring in 1964 for the northern hemisphere, and in 1966 for the southern hemisphere. The level has since dropped, as this bomb pulse or "bomb carbon" (as it
17098-424: The equation above. The half-life of a radioactive isotope (usually denoted by t 1/2 ) is a more familiar concept than the mean-life, so although the equations above are expressed in terms of the mean-life, it is more usual to quote the value of C 's half-life than its mean-life. The currently accepted value for the half-life of C is 5,700 ± 30 years. This means that after 5,700 years, only half of
17264-468: The errors caused by the variation over time in the C / C ratio. These curves are described in more detail below . Coal and oil began to be burned in large quantities during the 19th century. Both are sufficiently old that they contain little or no detectable C and, as a result, the CO 2 released substantially diluted the atmospheric C / C ratio. Dating an object from
17430-429: The examination and registration process was carried out by each prefecture, and the criteria for examination varied. Around 1925, the results of the improvements became visible: the negative characteristics of crossbreeding had almost disappeared from Wagyu cattle, their size and weight had increased, and improvements in hindquarters were clearly visible. In 1937, when the former Japan Livestock Industry Association became
17596-423: The first appearance of European loanwords . The basis of the standard dialect moved from the Kansai region to the Edo region (modern Tokyo ) in the Early Modern Japanese period (early 17th century–mid 19th century). Following the end of Japan's self-imposed isolation in 1853, the flow of loanwords from European languages increased significantly, and words from English roots have proliferated. Japanese
17762-501: The first slaughter of cattle by foreigners in the pine forests of Cape Wadamisaki. In this way, foreign ships bought 30 or 40 cows at a time in Kobe before the official opening of the port and brought them to Yokohama, where " Kobe beef " (actually Tajima beef ) became well known for its delicious taste. In January 1868, when the new port of Kobe opened east of Hyogo Port, the Kobe foreign settlement
17928-626: The former Nanbu Domain territory in northeastern Japan (present-day Iwate Prefecture) with Shorthorns and other breeds imported from the United States, but P has not been detected in Shorthorns and is thought to be derived from the Nanbu cattle. Fossils of Hanaizumi Moriushi and Aurochs have been found in Iwate Prefecture, but it is unclear if the Nanbu cattle were related to these. Haplogroup P has also been found in Chinese and Korean cattle, but it
18094-908: The former is much easier to measure, and the latter can be easily derived: the depletion of C relative to C is proportional to the difference in the atomic masses of the two isotopes, so the depletion for C is twice the depletion of C . The fractionation of C , known as δ C , is calculated as follows: δ C 13 = ( ( C 13 C 12 ) sample ( C 13 C 12 ) standard − 1 ) × 1000 {\displaystyle \delta {\ce {^{13}C}}=\left({\frac {\left({\frac {{\ce {^{13}C}}}{{\ce {^{12}C}}}}\right)_{\text{sample}}}{\left({\frac {{\ce {^{13}C}}}{{\ce {^{12}C}}}}\right)_{\text{standard}}}}-1\right)\times 1000} ‰ where
18260-609: The genitive particle ga remains in intentionally archaic speech. Early Middle Japanese is the Japanese of the Heian period , from 794 to 1185. It formed the basis for the literary standard of Classical Japanese , which remained in common use until the early 20th century. During this time, Japanese underwent numerous phonological developments, in many cases instigated by an influx of Chinese loanwords . These included phonemic length distinction for both consonants and vowels , palatal consonants (e.g. kya ) and labial consonant clusters (e.g. kwa ), and closed syllables . This had
18426-454: The initial C will remain; a quarter will remain after 11,400 years; an eighth after 17,100 years; and so on. The above calculations make several assumptions, such as that the level of C in the atmosphere has remained constant over time. In fact, the level of C in the atmosphere has varied significantly and as a result, the values provided by the equation above have to be corrected by using data from other sources. This
18592-404: The inner tree rings do not get their C replenished and instead only lose C through radioactive decay. Hence each ring preserves a record of the atmospheric C / C ratio of the year it grew in. Carbon-dating the wood from the tree rings themselves provides the check needed on the atmospheric C / C ratio: with a sample of known date, and a measurement of
18758-659: The laboratory's cyclotron accelerator and soon discovered that the atom's half-life was far longer than had been previously thought. This was followed by a prediction by Serge A. Korff , then employed at the Franklin Institute in Philadelphia , that the interaction of thermal neutrons with N in the upper atmosphere would create C . It had previously been thought that C would be more likely to be created by deuterons interacting with C . At some time during World War II, Willard Libby , who
18924-453: The languages of the original Jōmon inhabitants, including the ancestor of the modern Ainu language . Because writing had yet to be introduced from China, there is no direct evidence, and anything that can be discerned about this period must be based on internal reconstruction from Old Japanese , or comparison with the Ryukyuan languages and Japanese dialects . The Chinese writing system
19090-449: The languages. Okinawan Japanese is a variant of Standard Japanese influenced by the Ryūkyūan languages, and is the primary dialect spoken among young people in the Ryukyu Islands . Modern Japanese has become prevalent nationwide (including the Ryūkyū islands) due to education , mass media , and an increase in mobility within Japan, as well as economic integration. Japanese is a member of
19256-427: The large quantity of English loanwords, modern Japanese has developed a distinction between [tɕi] and [ti] , and [dʑi] and [di] , with the latter in each pair only found in loanwords. Although Japanese is spoken almost exclusively in Japan, it has also been spoken outside of the country. Before and during World War II , through Japanese annexation of Taiwan and Korea , as well as partial occupation of China ,
19422-502: The neighbourhood of the Furnas caldera in the Azores were found to have apparent ages that ranged from 250 years to 3320 years. Any addition of carbon to a sample of a different age will cause the measured date to be inaccurate. Contamination with modern carbon causes a sample to appear to be younger than it really is: the effect is greater for older samples. If a sample that is 17,000 years old
19588-593: The number of stud bulls owned by breed as of 1914 was as follows. Even after the Meiji era when hybrid cattle were encouraged, there were still a considerable number of pure Wagyu cattle remaining in the Taisho era (1912–1926). As a policy for the improvement of Wagyu, efforts were made to eliminate negative characteristics of hybrid cattle as much as possible. Specifically, the elimination of sudare (tiger stripes), nori-kuchi (grayish-white lips), unagi-sen (different fur color on
19754-435: The number of superior Wagyu cattle began. According to a survey conducted in 1914, there were 61 different breeds of Wagyu in Japan at that time, including Tajima cattle , Iwaizumi cattle, Mishima cattle, Aso cattle, and others. However, these were not actual breeds, but only names of regional classifications. In the case of Hyōgo Prefecture, the leading producer of Wagyu cattle ( Kobe cattle and Tajima cattle) at that time,
19920-420: The ocean surface have the same C ratios as the water they live in, and as a result of the reduced C / C ratio, the radiocarbon age of marine life is typically about 400 years. Organisms on land are in closer equilibrium with the atmosphere and have the same C / C ratio as the atmosphere. These organisms contain about 1.3% of the carbon in the reservoir; sea organisms have
20086-425: The only strict rule of word order is that the verb must be placed at the end of a sentence (possibly followed by sentence-end particles). This is because Japanese sentence elements are marked with particles that identify their grammatical functions. The basic sentence structure is topic–comment . For example, Kochira wa Tanaka-san desu ( こちらは田中さんです ). kochira ("this") is the topic of the sentence, indicated by
20252-635: The organism from which the sample was taken died), and N is the number of atoms left after time t . λ is a constant that depends on the particular isotope; for a given isotope it is equal to the reciprocal of the mean-life – i.e. the average or expected time a given atom will survive before undergoing radioactive decay. The mean-life, denoted by τ , of C is 8,267 years, so the equation above can be rewritten as: t = ln ( N 0 / N ) ⋅ 8267 years {\displaystyle t=\ln(N_{0}/N)\cdot {\text{8267 years}}} The sample
20418-541: The other hand, recent genetic studies have shown that Wagyu and Korean cattle ( Hanwoo and others) differ greatly in their genetic information. Livestock cattle are divided into two major lineages: northern lineage cattle ( Bos taurus ) and Indian lineage cattle ( Bos indicus ), and both Wagyu and Korean cattle belong to the northern lineage and do not contain Indian lineage such as Zebu cattle. However, in terms of mitochondrial DNA haplogroups , haplogroup T4 (East Asian type)
20584-534: The other three Wagyu breeds has decreased. Following the outbreak of Bovine Spongiform Encephalopathy (BSE) in Japan, the Law for Special Measures Concerning the Management and Relay of Information for Individual Identification of Cattle (Beef Traceability Law) was enacted in 2003. This law stipulates the attachment of ear tags to cattle, the notification, recording, and storage of historical information from birth to beef, and
20750-470: The out-group gives a benefit to the in-group, and "up" to indicate the in-group gives a benefit to the out-group. Here, the in-group includes the speaker and the out-group does not, and their boundary depends on context. For example, oshiete moratta ( 教えてもらった ) (literally, "explaining got" with a benefit from the out-group to the in-group) means "[he/she/they] explained [it] to [me/us]". Similarly, oshiete ageta ( 教えてあげた ) (literally, "explaining gave" with
20916-415: The particle wa . The verb desu is a copula , commonly translated as "to be" or "it is" (though there are other verbs that can be translated as "to be"), though technically it holds no meaning and is used to give a sentence 'politeness'. As a phrase, Tanaka-san desu is the comment. This sentence literally translates to "As for this person, (it) is Mx Tanaka." Thus Japanese, like many other Asian languages,
21082-440: The plants and freshwater organisms that live in it. This is known as the hard water effect because it is often associated with calcium ions, which are characteristic of hard water; other sources of carbon such as humus can produce similar results, and can also reduce the apparent age if they are of more recent origin than the sample. The effect varies greatly and there is no general offset that can be applied; additional research
21248-413: The pre-existing Egyptian chronology nor the new radiocarbon dating method could be assumed to be accurate, but a third possibility was that the C / C ratio had changed over time. The question was resolved by the study of tree rings : comparison of overlapping series of tree rings allowed the construction of a continuous sequence of tree-ring data that spanned 8,000 years. (Since that time
21414-409: The previous year, and as a result, Japan's beef self-sufficiency rate dropped below 50%. The liberalization of beef imports has brought about changes in Japan's domestic Wagyu beef production system. In order to compete with cheaper foreign beef, Japanese livestock farmers have become more focused on raising the Japanese Black breed, which has a unique marbling characteristic. As a result, the number of
21580-477: The proposed larger Altaic family, or to various Southeast Asian languages , especially Austronesian . None of these proposals have gained wide acceptance (and the Altaic family itself is now considered controversial). As it stands, only the link to Ryukyuan has wide support. Other theories view the Japanese language as an early creole language formed through inputs from at least two distinct language groups, or as
21746-514: The publication of recorded information on the Internet. In other words, it is possible to trace the history of all Japanese beef sold in Japan. Most of today's Wagyu are improved Wagyu ( 改良和牛 , kairyō wagyū ) that have been fixed as breeds through crossbreeding with foreign breeds. There are four breeds of improved Wagyu as follows: Native Wagyu ( 在来和牛 , zairai wagyū ) are cattle from ancient Japan that have not been crossbred with foreign breeds. It
21912-405: The ratios in the atmosphere. This effect is known as isotopic fractionation. To determine the degree of fractionation that takes place in a given plant, the amounts of both C and C isotopes are measured, and the resulting C / C ratio is then compared to a standard ratio known as PDB. The C / C ratio is used instead of C / C because
22078-484: The red meat that make it tender and moist, while adding flavor. Wagyu beef is often known by different names depending on its place of origin. In several Japanese prefectures , Wagyu beef is shipped with an area name; examples include Matsusaka beef , Kobe beef from the Tajima cattle , Yonezawa beef and Ōmi beef . In recent years, Wagyu beef has increased in fat percentage due to a decrease in grazing and an increase in
22244-415: The same over the preceding few thousand years. To verify the accuracy of the method, several artefacts that were datable by other techniques were tested; the results of the testing were in reasonable agreement with the true ages of the objects. Over time, however, discrepancies began to appear between the known chronology for the oldest Egyptian dynasties and the radiocarbon dates of Egyptian artefacts. Neither
22410-456: The same proportion of C as the atmosphere, or in the case of marine animals or plants, with the ocean. Once it dies, it ceases to acquire C , but the C within its biological material at that time will continue to decay, and so the ratio of C to C in its remains will gradually decrease. Because C decays at a known rate, the proportion of radiocarbon can be used to determine how long it has been since
22576-459: The same structure as affirmative sentences, but with intonation rising at the end. In the formal register, the question particle -ka is added. For example, ii desu ( いいです ) "It is OK" becomes ii desu-ka ( いいですか。 ) "Is it OK?". In a more informal tone sometimes the particle -no ( の ) is added instead to show a personal interest of the speaker: Dōshite konai-no? "Why aren't (you) coming?". Some simple queries are formed simply by mentioning
22742-412: The sample since its burial. Alkali and acid washes can be used to remove humic acid and carbonate contamination, but care has to be taken to avoid removing the part of the sample that contains the carbon to be tested. Particularly for older samples, it may be useful to enrich the amount of C in the sample before testing. This can be done with a thermal diffusion column. The process takes about
22908-797: The state as at the time the constitution was written, many of the elders participating in the process had been educated in Japanese during the South Seas Mandate over the island shown by the 1958 census of the Trust Territory of the Pacific that found that 89% of Palauans born between 1914 and 1933 could speak and read Japanese, but as of the 2005 Palau census there were no residents of Angaur that spoke Japanese at home. Japanese dialects typically differ in terms of pitch accent , inflectional morphology , vocabulary , and particle usage. Some even differ in vowel and consonant inventories, although this
23074-476: The street. (grammatically incorrect insertion of a pronoun) But one can grammatically say essentially the same thing in Japanese: 驚いた彼は道を走っていった。 Transliteration: Odoroita kare wa michi o hashitte itta. (grammatically correct) This is partly because these words evolved from regular nouns, such as kimi "you" ( 君 "lord"), anata "you" ( あなた "that side, yonder"), and boku "I" ( 僕 "servant"). This
23240-401: The surface water as carbonate and bicarbonate ions; at the same time the carbonate ions in the water are returning to the air as CO 2 . This exchange process brings C from the atmosphere into the surface waters of the ocean, but the C thus introduced takes a long time to percolate through the entire volume of the ocean. The deepest parts of the ocean mix very slowly with
23406-590: The surface waters, and as a result water from some deep ocean areas has an apparent radiocarbon age of several thousand years. Upwelling mixes this "old" water with the surface water, giving the surface water an apparent age of about several hundred years (after correcting for fractionation). This effect is not uniform – the average effect is about 400 years, but there are local deviations of several hundred years for areas that are geographically close to each other. These deviations can be accounted for in calibration, and users of software such as CALIB can provide as an input
23572-422: The surface waters, and the mixing is uneven. The main mechanism that brings deep water to the surface is upwelling, which is more common in regions closer to the equator. Upwelling is also influenced by factors such as the topography of the local ocean bottom and coastlines, the climate, and wind patterns. Overall, the mixing of deep and surface waters takes far longer than the mixing of atmospheric CO 2 with
23738-621: The topic with an interrogative intonation to call for the hearer's attention: Kore wa? "(What about) this?"; O-namae wa? ( お名前は？ ) "(What's your) name?". Negatives are formed by inflecting the verb. For example, Pan o taberu ( パンを食べる。 ) "I will eat bread" or "I eat bread" becomes Pan o tabenai ( パンを食べない。 ) "I will not eat bread" or "I do not eat bread". Plain negative forms are i -adjectives (see below) and inflect as such, e.g. Pan o tabenakatta ( パンを食べなかった。 ) "I did not eat bread". Radiocarbon dating Radiocarbon dating (also referred to as carbon dating or carbon-14 dating )
23904-478: The tree-ring data series has been extended to 13,900 years.) In the 1960s, Hans Suess was able to use the tree-ring sequence to show that the dates derived from radiocarbon were consistent with the dates assigned by Egyptologists. This was possible because although annual plants, such as corn, have a C / C ratio that reflects the atmospheric ratio at the time they were growing, trees only add material to their outermost tree ring in any given year, while
24070-589: The turn of the era to the 5th century. In 675, due to the influence of Buddhism, Emperor Tenmu issued a decree banning meat eating, and eating cattle was officially prohibited in Japan. However, a study of human excrement excavated from the Heijo Palace site has revealed that Japanese people in the Nara period (710–794) continued to eat cattle even after the prohibition. In addition, the Yoro Code (757) stipulates that when
24236-419: The two consonants are the moraic nasal followed by a homorganic consonant. Japanese also includes a pitch accent , which is not represented in moraic writing; for example [haꜜ.ɕi] ("chopsticks") and [ha.ɕiꜜ] ("bridge") are both spelled はし ( hashi ) , and are only differentiated by the tone contour. Japanese word order is classified as subject–object–verb . Unlike many Indo-European languages ,
24402-577: The two methods were both used in writing until the 1940s. Bungo still has some relevance for historians, literary scholars, and lawyers (many Japanese laws that survived World War II are still written in bungo , although there are ongoing efforts to modernize their language). Kōgo is the dominant method of both speaking and writing Japanese today, although bungo grammar and vocabulary are occasionally used in modern Japanese for effect. The 1982 state constitution of Angaur , Palau , names Japanese along with Palauan and English as an official language of
24568-413: The two terms (''hyōjungo'' and ''kyōtsūgo'') are almost the same. Hyōjungo or kyōtsūgo is a conception that forms the counterpart of dialect. This normative language was born after the Meiji Restoration ( 明治維新 , meiji ishin , 1868) from the language spoken in the higher-class areas of Tokyo (see Yamanote ). Hyōjungo is taught in schools and used on television and in official communications. It
24734-404: The two. The atmospheric C / C ratio is lower in the southern hemisphere, with an apparent additional age of about 40 years for radiocarbon results from the south as compared to the north. This is because the greater surface area of ocean in the southern hemisphere means that there is more carbon exchanged between the ocean and the atmosphere than in the north. Since the surface ocean
24900-490: The use of feed , resulting in larger, fattier cattle. Wagyu refers to "Japanese cattle" and is not a specific breed, derived from "Wa" means Japanese and "Gyu" means cow. Japanese native cattle became almost extinct after the Meiji Restoration (1868), mainly as a result of crossbreeding with European breeds, with exceptions such as the Mishima cattle . There are only a few hundred Japanese native cattle, and meat from these cattle
25066-434: The value of N (the number of atoms of C remaining in the sample), the carbon-dating equation allows the calculation of N 0 – the number of atoms of C in the sample at the time the tree ring was formed – and hence the C / C ratio in the atmosphere at that time. Equipped with the results of carbon-dating the tree rings, it became possible to construct calibration curves designed to correct
25232-407: The verb (e.g. yonde for earlier yomite ), the -k- in the final mora of adjectives drops out ( shiroi for earlier shiroki ); and some forms exist where modern standard Japanese has retained the earlier form (e.g. hayaku > hayau > hayɔɔ , where modern Japanese just has hayaku , though the alternative form is preserved in the standard greeting o-hayō gozaimasu "good morning"; this ending
25398-513: The world's oldest specialized book on bulls. In the same book, the names of 52 bulls are listed as swift bulls. At the time, the cattle from Iki Island in present-day Nagasaki Prefecture had the highest reputation as swift bulls, but they were temporarily destroyed by the Mongolian army during the Mongolian invasion , which killed them and used them as food. From the Kamakura period (1185–1333) to
25564-548: The world. Since Japanese first gained the consideration of linguists in the late 19th century, attempts have been made to show its genealogical relation to languages or language families such as Ainu , Korean , Chinese , Tibeto-Burman , Uralic , Altaic (or Ural-Altaic ), Austroasiatic , Austronesian and Dravidian . At the fringe, some linguists have even suggested a link to Indo-European languages , including Greek , or to Sumerian . Main modern theories try to link Japanese either to northern Asian languages, like Korean or
25730-494: The ‰ sign indicates parts per thousand . Because the PDB standard contains an unusually high proportion of C , most measured δ C values are negative. For marine organisms, the details of the photosynthesis reactions are less well understood, and the δ C values for marine photosynthetic organisms are dependent on temperature. At higher temperatures, CO 2 has poor solubility in water, which means there
25896-411: Was awarded the Nobel Prize in Chemistry for this work. In nature, carbon exists as three isotopes . Carbon-12 ( C ) and carbon-13 ( C ) are stable and nonradioactive; carbon-14 ( C ), also known as "radiocarbon", is radioactive. The half-life of C (the time it takes for half of a given amount of C to decay ) is about 5,730 years, so its concentration in
26062-535: Was based on 12- to 20-second-long recordings of 135 to 244 phonemes , which 42 students listened to and translated word-for-word. The listeners were all Keio University students who grew up in the Kanto region . There are some language islands in mountain villages or isolated islands such as Hachijō-jima island , whose dialects are descended from Eastern Old Japanese . Dialects of the Kansai region are spoken or known by many Japanese, and Osaka dialect in particular
26228-455: Was based on pure Wagyu and improved Wagyu (crossbred cattle). In October 1912, when the 6th Chugoku Six Prefectures United Livestock Breeders' Show was held in Himeji City , Hyōgo Prefecture, two crossbred bulls won first prize as "Improved Japanese Breed" (改良和種, kairyō washu ) and the term "Improved Japanese Breed" came into use thereafter. Thereafter, organized breeding efforts to increase
26394-439: Was established. In 1868, Englishman Edward Charles Kirby established the first slaughterhouse in Kobe, and in 1869, a sukiyaki restaurant called "Gekka-tei" opened there. According to a newspaper article in 1875, Kobe was the first place where meat eating was popular, with 800 cows slaughtered in a month. Next was Yokohama with 600, followed by Tokyo with 500, and Osaka and Nagoya with 300. The reputation of Wagyu beef as having
26560-524: Was frowned upon and the use of milk was not widespread, cows in the Edo period were primarily work cattle that plowed the fields, so a good cow in this period meant one that was healthy and obedient. The famous "Tajiri-go" bull was born from the "Atsuta tsuru ," which is a descendant of the Shusuke tsuru . According to a survey conducted by the Japan Wagyu Registry Association , the pedigree
26726-668: Was imported to Japan from Baekje around the start of the fifth century, alongside Buddhism. The earliest texts were written in Classical Chinese , although some of these were likely intended to be read as Japanese using the kanbun method, and show influences of Japanese grammar such as Japanese word order. The earliest text, the Kojiki , dates to the early eighth century, and was written entirely in Chinese characters, which are used to represent, at different times, Chinese, kanbun , and Old Japanese. As in other texts from this period,
26892-465: Was lost immediately following its composition.) This set of morae shrank to 67 in Early Middle Japanese , though some were added through Chinese influence. Man'yōgana also has a symbol for /je/ , which merges with /e/ before the end of the period. Several fossilizations of Old Japanese grammatical elements remain in the modern language – the genitive particle tsu (superseded by modern no )
27058-458: Was reported in Japanese cattle and became a major social problem. Since then, stringent testing and registration measures for cattle in Japan have been implemented. Since 2007, only four breeds of kairyō wagyū and their crossbreds, as well as cattle born, raised, and duly registered in Japan, have been allowed to be labeled as Wagyu. Western breeds such as Holstein and Jersey are also raised in Japan for dairy cattle. When meat from these cattle
27224-780: Was then at Berkeley, learned of Korff's research and conceived the idea that it might be possible to use radiocarbon for dating. In 1945, Libby moved to the University of Chicago , where he began his work on radiocarbon dating. He published a paper in 1946 in which he proposed that the carbon in living matter might include C as well as non-radioactive carbon. Libby and several collaborators proceeded to experiment with methane collected from sewage works in Baltimore, and after isotopically enriching their samples they were able to demonstrate that they contained C . By contrast, methane created from petroleum showed no radiocarbon activity because of its age. The results were summarized in
27390-460: Was traced from a database of 718,969 Japanese black cattle mothers registered in Japan, and it was found that 718,330 or 99.9% of them are descended from the Tajiri-go. On the other hand, there are those who are concerned about the current situation in which only the Tajima cattle line represented by the Tajiri-go is spreading and genetic diversity is being lost from Wagyu, and the movement to revive
27556-569: Was urgently needed. Between 1868, the year of the Meiji Restoration, and 1887, some 2600 foreign cattle were imported. At first, there was little interest in cross-breeding these with the native stock, but from about 1900, it became widespread. In 1900, the Japanese government established a committee to investigate the improvement of cattle breeding, and began a systematic crossbreeding program between Wagyu and Western breeds. The Ayrshire and Simmental breeds were imported first, followed by
