It then rapidly modernized under the Meiji Restoration , while Joseon continued to resist foreign attempts to open it up. Japan eventually succeeded in opening Joseon with the unequal Japan–Korea Treaty of 1876 . Afterwards, Japan embarked on a decades-long process of defeating its local rivals, securing alliances with Western powers, and asserting its influence in Korea. Japan assassinated
360-625: A considerable number of properties were destroyed by Korean residents. Republic of China further alleged the Japanese authorities in Korea did not take adequate steps to protect the lives and property of the Chinese residents, and blamed the authorities for allowing inflammatory accounts to be published. As a result of this riot, the Minister of Foreign Affairs Kijūrō Shidehara , who insisted on Japanese, Chinese, and Korean harmony, lost his position. In 1911,

After the Korean army was disbanded in 1907, former soldiers joined the armies and fought the Japanese army at Namdaemun . They were defeated, and largely fled into Manchuria, where they joined the guerrilla resistance movement that persisted until Korea's 1945 liberation. As Korean resistance against Japanese rule intensified, Japanese replaced Korean police system with their military police. Infamous Akashi Motojiro

While the international consensus is that these incidents all occurred, various Japanese scholars and politicians, including Tokyo governor Yuriko Koike , either deny completely, attempt to justify, or downplay incidents such as these. Beginning in 1939 and during World War II , Japan mobilized around 5.4 million Koreans to support its war effort. Many were moved forcefully from their homes, and set to work in generally extremely poor working conditions, although there

The farm, whose English name is given as the Pukchong Pig Farm, is said to include an inspection room, fattening and breeding blocks, a feed processing and transportation system, as well as a means to produce organic fertilizer. Pukch'ŏng county is served by the Tŏksŏng and P'yŏngra lines of the Korean State Railway , as well as by roads. Sea of Japan The Sea of Japan ( see below for other names)
1200-590: A process of Japanization , eventually functionally banning the use of Korean names and the Korean language altogether. Tens of thousands of cultural artifacts were taken to Japan, and hundreds of historic buildings like the royal palaces Gyeongbokgung and Deoksugung were either partially or completely demolished. Japan also built infrastructure and industry. Railways, ports and roads were constructed, although in numerous cases workers were subjected to extremely poor working circumstances and discriminatory pay. While Korea's economy grew under Japan, many argue that many of

They accelerate in the Korea Strait (40–60 cm/s or 16–24 in/s), La Pérouse Strait (50–100 cm/s or 20–40 in/s) and especially in the Tsugaru Strait (100–200 cm/s or 40–80 in/s). The amplitude of the tides is relatively low and varies strongly across the sea. It reaches 3 meters in the south near the Korea Strait, but quickly drops northwards to 1.5 m (5 ft) at
1680-670: A total population of over 21 million, less than 3%. By 1939 the Japanese population increased to 651,000, mostly from Japan's western prefectures. During the same period, the population in Chōsen grew faster than that in the naichi . Koreans also migrated to the naichi in large numbers, especially after 1930; by 1939 there were over 981,000 Koreans living in Japan. Challenges which deterred Japanese from migrating into Chōsen included lack of arable land and population density comparable to that of Japan. Japan sent anthropologists to Korea who took photos of

The evaporation is blown further south, causing snowfall in the mountainous western coasts of Japan. This winter monsoon brings typhoons and storms, with the waves reaching 8–10 m (26–33 ft) which erode the western coasts of Japan. Tsunami waves have also been recorded in
2400-625: Is exemplified in the legacy of Park Chung Hee , South Korea's most influential and controversial president, who collaborated with the Japanese military and continued to praise it even after the colonial period. Until 1964, South Korea and Japan had no functional diplomatic relations, until they signed the Treaty on Basic Relations , which declared "already null and void " the past unequal treaties, especially those of 1905 and 1910. Despite this, relations between Japan and South Korea have oscillated between warmer and colder periods, often due to conflicts over

The intensity of shipments across the sea has been moderate owing to political issues, but it is steadily increasing as a result of the growth of East Asian economies. Sea of Japan is the dominant term used in English for the sea, and the name in most European languages is equivalent, but it is sometimes called by different names in surrounding countries. The sea
2880-502: Is the lowest at 33.8‰ in the south-east and south-west because of frequent rains, and remains at about 34.09‰ in most other parts. Thawing of ice in spring reduces water salinity in the north, but it remains high at 34.60–34.70‰ in the south, partly because of the inflow of salty water through the Korea Strait . A typical variation of salinity across the sea in summer is 31.5‰ to 34.5‰ from north to south. The depth distribution of salinity

The Korea Strait is composed of the Western Channel and the Tsushima Strait , on either side of Tsushima Island . The straits were formed in recent geologic periods. The oldest of them are
3120-636: The Donghak Peasant Revolution in 1894 provided a seminal pretext for direct military intervention by Japan in the affairs of Korea. In April 1894, Joseon asked for Chinese assistance in ending the revolt. In response, Japanese leaders, citing a violation of the Convention of Tientsin as a pretext, decided upon military intervention to challenge China. On 3 May 1894, 1,500 Qing forces appeared in Incheon . On 23 July 1894, Japan attacked Seoul in defiance of

The north part of the Japanese archipelago was further fragmented later until orogenesis of the north-eastern Japanese archipelago began in the later Late Miocene . The south part of the Japanese archipelago remained as a relatively large landmass. The land area had expanded northward in the Late Miocene. The orogenesis of high mountain ranges in north-eastern Japan started in Late Miocene and lasted in Pliocene also. The eastern margin of

After forcing the Korean Emperor Gojong to abdicate in 1907, Japan then formally colonized Korea with the Japan–Korea Treaty of 1910 . The territory was then administered by the Governor-General of Chōsen , based in Keijō (Seoul), until the end of the colonial period. Japan made sweeping changes in Korea. It began

It is also reflected in various legends, such as the legend of the Heishi rock , which says that once when herring vanished, an old fairy threw a bottle with magic water into the sea, and the herring returned. The bottle got stuck to the seabed and turned into a rock, which became a representation of the God of the Sea of Japan. Vladivostok is a base for the Russian whaling fleet. Although it operates in
3720-544: The Minister of War of Japan , Terauchi Masatake , was given a mission to finalize Japanese control over Korea after the previous treaties (the Japan–Korea Treaty of 1904 and the Japan–Korea Treaty of 1907 ) had made Korea a protectorate of Japan and had established Japanese hegemony over Korean domestic politics. On 22 August 1910, Japan effectively annexed Korea with the Japan–Korea Treaty of 1910 signed by Ye Wanyong , Prime Minister of Korea, and Terauchi Masatake, who became

There is a significant range of opinions in both South Korea and Japan, and historical topics regularly cause diplomatic issues. Within South Korea, a particular focus is the role of the numerous ethnic Korean collaborators with Japan , who have been variously punished or left alone. This controversy
5520-536: The altar. Having established economic and military dominance in Korea in October 1904, Japan reported that it had developed 25 reforms which it intended to introduce into Korea by gradual degrees. Among these was the intended acceptance by the Korean Financial Department of a Japanese Superintendent, the replacement of Korean Foreign Ministers and consuls by Japanese and the "union of military arms" in which
5640-534: The amount of land taken over by private Japanese companies. Many former Korean landowners, as well as agricultural workers, became tenant farmers , having lost their entitlements almost overnight because they could not pay for the land reclamation and irrigation improvements forced on them. Compounding the economic stresses imposed on the Korean peasantry, the authorities forced Korean peasants to do long days of compulsory labor to build irrigation works; Japanese imperial officials made peasants pay for these projects in
5760-413: The amount they took to eat dropped precipitously, causing much resentment among them. By 1910 an estimated 7 to 8% of all arable land in Korea had come under Japanese control. This ratio increased steadily; as of the years 1916, 1920, and 1932, the ratio of Japanese land ownership increased from 36.8 to 39.8 to 52.7%. The level of tenancy was similar to that of farmers in Japan itself; however, in Korea,

6840-413: The dominant name is a point of contention. South Korea wants the name "East Sea" to be used, either instead of or in addition to "Sea of Japan;" while North Korea prefers the name "East Sea of Korea". The primary issue in the dispute revolves around a disagreement about when the name "Sea of Japan" became the international standard. Japan claims the term has been the international standard since at least

Russian expeditions were made in 1853–1854 and 1886–1889 to measure the surface temperatures and record the tides. They also documented
8280-425: The help of Chinese forces stationed in Korea. The coup was put down by Chinese troops, and a Korean mob killed both Japanese officers and Japanese residents in retaliation. Some leaders of the Progressive Party, including Kim Ok-gyun , fled to Japan, while others were executed. For the next 10 years, Japanese expansion into the Korean economy was approximated only by the efforts of tsarist Russia . The outbreak of
8400-729: The historiography of this era. During the period of Japanese colonial rule, Korea was officially known as Chōsen ( 朝鮮 ) , although the former name continued to be used internationally. In South Korea, the period is usually described as the "Imperial Japanese compulsive occupation period" ( Korean : 일제강점기 ; Hanja : 日帝强占期 ; RR : Ilje Gangjeomgi ). Other terms, although often considered obsolete, include "Japanese Imperial Period" ( 일제시대 ; 日帝時代 ; Ilje Sidae ), "The dark Japanese Imperial Period" ( 일제암흑기 ; 日帝暗黑期 ; Ilje Amheukgi ), and " Wae (Japanese) administration period" ( 왜정시대 ; 倭政時代 ; Wae-jeong Sidae ). In Japan,
8520-513: The ice cap advances of the last Ice Age , the exit straits of the Sea of Japan one by one dried and closed. There is controversy as to whether or not in each ice cap advance the world sea level fell low enough for the deepest, the western channel of the Korea Strait , to dry and close, turning the Sea of Japan into a huge cold inland lake with a surface layer of fresh water, freezing over in the winters. The sea climate has warm waters and monsoons. This combination results in strong evaporation, which
8640-549: The infrastructure projects were designed to extract resources from the peninsula, and not to benefit its people. Most of Korea's infrastructure built during this time was destroyed during the 1950–1953 Korean War . These conditions led to the birth of the Korean independence movement , which acted both politically and militantly sometimes within the Japanese Empire, but mostly from outside of it. Koreans were also subjected to
8760-435: The lack of experts in Korean art at overseas museums and institutions, alterations made to artifacts that obscure their origin, and that moving Korean artifacts within what was previously internationally recognized Japanese territory was lawful at the time. The South Korean government has been continuing its efforts to repatriate Korean artifacts from museums and private collections overseas. The royal palace Gyeongbokgung
8880-563: The landowners were mostly Japanese, while the tenants were all Koreans. As often occurred in Japan itself, tenants had to pay over half their crop in rent. By the 1930s the growth of the urban economy and the exodus of farmers to the cities had gradually weakened the hold of the landlords. With the growth of the wartime economy throughout the Second World War , the government recognized landlordism as an impediment to increased agricultural productivity, and took steps to increase control over
9000-461: The last ruler of the Joseon dynasty, founded in 1392. On 24 July 1907, a treaty was signed under the leadership of Lee Wan-yong and Ito Hirobumi to transfer all rights of Korea to Japan . This led to a large-scale righteous army movement among Koreans, and disbanded troops joined the resistance forces. Japan's response to this was a scorched earth tactic using division-sized troops, which resulted in
9120-624: The limits of the "Japan Sea" as follows: On the Southwest. The Northeastern limit of the Eastern China Sea [From Nomo Saki (32°35′ N) in Kyusyu to the South point of Hukae Sima ( Goto Retto ) and on through this island to Ose Saki (Cape Goto) and to Hunan Kan, the South point of Saisyu To (Quelpart), through this island to its Western extreme and thence along the parallel of 33°17′ North to
9240-841: The mainland] and the Western limit of the Inland Sea [defined circuitously as "The Southeastern limit of the Japan Sea"]. On the Southeast. In Simonoseki Kaikyo . A line running from Nagoya Saki (130°49′,5 E) in Kyûsyû through the islands of Uma Sima and Muture Sima (33°58′,5 N) to Murasaki Hana (34°01′ N) in Honsyû . On the East. In the Tsugaru Kaikô . From the extremity of Siriya Saki (141°28′ E) to
9360-495: The military efforts of World War II led to organized official recruitment of Koreans to work in mainland Japan, initially through civilian agents, and later directly, often involving elements of coercion. As the labor shortage increased, by 1942, the Japanese authorities extended the provisions of the National Mobilization Law to include the conscription of Korean workers for factories and mines in Korea, Manchukuo , and
9480-465: The military of Korea would be modeled after the Japanese military. These reforms were forestalled by the prosecution of the Russo-Japanese War from 8 February 1904, to 5 September 1905, which Japan won, thus eliminating Japan's last rival to influence in Korea. Frustrated by this, King Gojong invited Alice Roosevelt Longworth , who was on a tour of Asian countries with William Howard Taft , to
9600-502: The movement of armed resistance organizations in Korea to Manchuria. Amid this confusion, on 26 October 1909, Ahn Jung-geun , a former volunteer soldier, assassinated Ito Hirobumi in Harbin . Meanwhile, pro-Japanese populist groups such as the Iljinhoe helped Japan by being fascinated by Japan's pan-Asianism , thinking that Korea would have autonomy like Austria-Hungary . It was adopted as
9720-598: The north and the Tsushima Basin (Ulleung Basin) in the south-west. The Japan Basin is of oceanic origin and is the deepest part of the sea, whereas the Tsushima Basin is the shallowest with the depths below 2,300 m (7,500 ft). On the eastern shores, the continental shelves of the sea are wide, but on the western shores, particularly along the Korean coast, they are narrow, averaging about 30 km (19 mi). There are three distinct continental shelves in
9840-616: The north wing of the palace. The Heungseon Daewongun returned to the royal palace the same day. On 11 February 1896, Gojong and the crown prince fled for protection at the Russian legation in Seoul, from which he governed for about a year. In 1896, various Korean activists formed the Independence Club . They advocated a number of societal reforms, including democracy and a constitutional monarchy, and pushed for closer ties to Western countries in order to counterbalance Japanese influence. It went on to be influential in Korean politics for
9960-653: The north. There they merge into the Tsugaru Current and flow into the Pacific Ocean through the Tsugaru Strait. They also feed the Sōya Current and exit through the La Perouse Strait to the Sea of Okhotsk. The returning branch is composed of the Liman, North Korea and Central (or Mid-) Japan Sea currents which bring fresh and cold water along the Asian coast to the south. Water temperature is mostly affected by exchange with
10080-425: The northern part (above 44° N). They form a staircase-like structure with the steps slightly inclined southwards and submerged to the depths of 900–1,400 (3,000–4,600), 1,700–2,000 (5,600–6,600) and 2,300–2,600 m (7,500–8,500 ft). The last step sharply drops to the depths of about 3,500 m (11,500 ft) toward the central (deepest) part of the sea. The bottom of this part is relatively flat, but has
10200-514: The northern part of Japan and Sakhalin Island. The intensity of shipments across the sea is moderate, owing to the cold relations between many bordering countries. As a result, the largest Japanese ports are on the Pacific coast, and the significant ports on the Sea of Japan are Niigata , Tsuruta and Maizuru . Major South Korean ports are Busan , Ulsan , and Pohang situated on the south-eastern coast of
10320-436: The northern part of the sea in winter and is brought south by the sea currents; it is rather stable and is observed all through the year. The hydrological isolation of the Sea of Japan also results in slightly lower average water salinity (34.09‰, where ‰ means parts per thousand) compared with the Pacific Ocean. In winter, the highest salinity at 34.5‰ is observed in the south where evaporation dominates over precipitation. It
10440-562: The northern seas, its production is processed and partly distributed in the Vladivostok area. Vladivostok is also a terminal point of the Trans-Siberian Railway which brings many goods to and from this major port . There is a regular ferry service across the Strait of Tartary between the Russian continental port of Vanino and Kholmsk in Sakhalin. The sea has magnetite sands as well as natural gas and petroleum fields near
10560-437: The open ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and the Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. The seawater has an elevated concentration of dissolved oxygen that results in high biological productivity. Therefore, fishing
10680-440: The order of 100 meters or less. This hinders water exchange, thereby isolating the water and aquatic life of the Sea of Japan from the neighboring seas and oceans. The sea has a surface area of about 1,050,000 km (410,000 sq mi), a mean depth of 1,752 m (5,748 ft) and a maximum depth of 4,568 m (14,987 ft). It has a carrot-like shape, with the major axis extending from south-west to north-east and
10800-523: The peak years of 1848 and 1849 a total of over 170 vessels (over 60 in 1848, and over 110 in 1849) cruised in the Sea of Japan, with significantly lesser numbers in following years. The Sea of Japan was landlocked when the land bridge of East Asia existed. The Japan Arc started to form in the Early Miocene . In the Early Miocene the Japan Sea started to open, and the northern and southern parts of
10920-499: The preferential treatment given to newly trained troops, the Daewongun's forces, or "old military", killed a Japanese training cadre, and attacked the Japanese legation . Japanese diplomats, policemen, students, and some Min clan members were also killed during the incident. The Daewongun was briefly restored to power, only to be forcibly taken to China by Chinese troops dispatched to Seoul to prevent further disorder. In August 1882,
11040-670: The proclamation "Matter Concerning the Changing of Korean Names" ( 朝鮮人ノ姓名改称ニ関スル件 ) was issued, barring ethnic Koreans from taking Japanese names and retroactively reverting the names of Koreans who had already registered under Japanese names back to the original Korean ones. By 1939, however, this position was reversed and Japan's focus had shifted towards cultural assimilation of the Korean people; Imperial Decree 19 and 20 on Korean Civil Affairs ( Sōshi-kaimei ) went into effect, whereby ethnic Koreans were forced to surrender their traditional use of clan-based Korean family name system, in favor of
11160-528: The rural sector through the formation in Japan in 1943 of the Central Agricultural Association ( 中央農会 , chūō nōkai ) , a compulsory organization under the wartime command economy . The Japanese government had hoped emigration to its colonies would mitigate the population boom in the naichi (内地), but had largely failed to accomplish this by 1936. According to figures from 1934, Japanese in Chōsen numbered approximately 561,000 out of
11280-563: The same time, Japan suppressed the peasant revolt with Korean government forces. The Japanese minister to Korea, Miura Gorō , orchestrated a plot against 43-year-old Queen Min (later given the title of " Empress Myeongseong "), and on 8 October 1895, she was assassinated by Japanese agents. In 2001, Russian reports on the assassination were found in the archives of the Foreign Ministry of the Russian Federation. The documents included
11400-403: The sea are of oceanic origin. Seabed down to 300 m (980 ft) is of continental nature and is covered with a mixture of mud, sand, gravel and fragments of rock. The depths between 300 and 800 m (980 and 2,620 ft) are covered in hemipelagic sediments (i.e., of semi-oceanic origin); these sediments are composed of blue mud rich in organic matter. Pelagic sediments of red mud dominate
11520-469: The sea may host an incipient subduction zone responsible for large earthquakes in 1940 , 1964 , 1983 and 1993 . Nowadays the Sea of Japan is bounded by the Russian mainland and Sakhalin island to the north, the Korean Peninsula to the west, and the Japanese islands of Hokkaidō , Honshū and Kyūshū to the east and south. It is connected to other seas by five straits : the Strait of Tartary between
11640-485: The sea through the Korea Strait and discharges through the Tsugaru (64% or 34,610 km [8,300 cu mi], La Pérouse 10,380 km [2,490 cu mi]) and Korea straits. Rainfall, evaporation and riverine inflow make only 1% of the water balance. Between October and April, the outflow exceeds the inflow due to the lower income through the Korea Strait; this balance reverses between May and September. The sea has complex tides , which are induced by
11760-543: The sea. In addition, the monsoon enhances the surface water convection, down to the depths of 30 m (98 ft). The coldest months are January and February, with an average air temperature of −20 °C (−4 °F) in the north and 5 °C (41 °F) in the south. The northern one-quarter of the sea, particularly the Siberian coast and the Strait of Tartary, freezes for about 4−5 months. The timing and extent of freezing vary from year to year, so ice may start forming in
11880-502: The short time that it operated, to the chagrin of Gojong. Gojong eventually forcefully disbanded the organization in 1898. In October 1897, Gojong returned to the palace Deoksugung , and proclaimed the founding of the Korean Empire at the royal altar Hwangudan . This symbolicly asserted Korea's independence from China, especially as Gojong demolished a reception hall that was once used to entertain Chinese ambassadors in order to build
12000-558: The small town of Wanpaoshan in Manchuria near Changchun , "violent clashes" broke out between the local Chinese and Korean immigrants on 2 July 1931. The Chosun Ilbo , a major Korean newspaper, misreported that many Koreans had died in the clashes, sparking a Chinese exclusion movement in urban areas of the Korean Peninsula. The worst of the rioting occurred in Pyongyang on 5 July. Approximately 127 Chinese people were killed, 393 wounded, and
12120-504: The southern tip of Korean Peninsula and to 0.5 m (1.6 ft) at the North Korean shores. Similar low tides are observed in Hokkaidō, Honshū and south Sakhalin. The amplitude however increases to 2.3–2.8 m (7.5–9.2 ft) toward the north of the Strait of Tartary due to its funnel-like shape. Apart from tides, the water level also displays seasonal, monsoon-related variations across
12240-404: The sun and tropical monsoons increases the depth gradient in spring–summer. In the north the surface layer (down to 15 m or 49 ft) may heat up to 18–20 °C (64–68 °F). The temperature would drop sharply to 4 °C (39 °F) at 50 m (160 ft), then slowly decrease to 1 °C (34 °F) at 250 m (820 ft) and remain so down to the seabed. On the contrary,
12360-427: The temperature in the south could gradually decrease to 6 °C (43 °F) at 200 m (660 ft), then to 2 °C (36 °F) at 260 m (850 ft) and to 0.04–0.14 °C (32.07–32.25 °F) at 1,000–1,500 m (3,300–4,900 ft), but then it would rise to about 0.3 °C (32.5 °F) near the bottom. This cold layer at about 1,000 m (3,300 ft) is formed by sinking of cold water in
12480-417: The temperature is almost constant with the depth in the northern part of the sea. However, in central-southern parts, it may be 8–10 °C (46–50 °F) down to 100–150 m (330–490 ft), 2–4 °C (36–39 °F) at 200–250 m (660–820 ft), 1.0–1.5 °C (33.8–34.7 °F) at 400–500 m (1,300–1,600 ft) and then remain at about 0 °C (32 °F) until the bottom. Heating by
12600-491: The term "Chōsen of the Japanese-Governed Period" ( 日本統治時代の朝鮮 , Nippon Tōchi-jidai no Chōsen ) has been used. On 27 February 1876, the Japan–Korea Treaty of 1876 was signed. It was designed to open up Korea to Japanese trade, and the rights granted to Japan under the treaty were similar to those granted Western powers in Japan following the visit of Commodore Perry in 1854. The treaty ended Korea's status as
12720-504: The testimony of King Gojong, several witnesses of the assassination, and Karl Ivanovich Weber 's report to Aleksey Lobanov-Rostovsky , the Foreign Minister of Russia, by Park Jonghyo. Weber was the chargé d'affaires at the Russian legation in Seoul at that time. According to a Russian eyewitness, Seredin-Sabatin, an employee of the king, a group of Japanese agents entered Gyeongbokgung , killed Queen Min, and desecrated her body in
12840-457: The tidal wave of the Pacific Ocean penetrating through the Korea Strait and Tsugaru strait. The tides are semi-diurnal (rise twice a day) in the Korea Strait and in the northern part of the Strait of Tartary. They are diurnal at the eastern shore of Korea, Russian Far East and the Japanese islands of Honshū and Hokkaidō. Mixed tides occur in Peter the Great Gulf and Korea strait. The tidal waves have
12960-495: The time of the First Sino-Japanese War of 1894–1895, Japanese merchants started settling in towns and cities in Korea seeking economic opportunity. By 1908 the number of Japanese settlers in Korea was somewhere below the figure of 500,000, comprising one of the nikkei communities in the world at the time. Many Japanese settlers showed interest in acquiring agricultural land in Korea even before Japanese land-ownership
13080-596: The traditional state of Korean villages, serving as evidence that Korea was "backwards" and needed to be modernized. In 1925, the Japanese government established the Korean History Compilation Committee , and it was administered by the Governor-General and engaged in collecting Korean historical materials and compiling Korean history. According to the Doosan Encyclopedia , some mythology
13200-411: The wind over a small (isolated) and tall obstacle, and usually forms over small mountainous islands. The Sea of Japan meets these conditions as it has frequent winds and cloudy skies, as well as compact, tall islands such as Rishiri (1,721 m or 5,646 ft), Ulleungdo (984 m or 3,228 ft) and Ōshima (732 m or 2,402 ft). The International Hydrographic Organization defines
13320-515: The world, abandoned its most recent of several attempts in the last 25 years to revise its publication of the sea's name. This was primarily because of the lack of agreement between the Koreas and Japan over the naming issue. In September 2020, the IHO announced that it would adopt a new numerical system, also known as "S-130". In November 2020, S-23, the previous version of the nautical chart made in 1953 will be made public as an IHO publication to demonstrate
13440-421: Was a range in what people experienced. Some Japanese politicians and scholars, including former Prime Minister Fumio Kishida , deny that Koreans were forced laborers, and instead claim that they were "requisitioned against their will" to work. Women and girls aged 12–17 were controversially forced into sexual slavery by Japan as " comfort women ". A number of modern Japanese scholars and politicians, notably from
13560-512: Was appointed for the commander of Japanese military police forces. Japanese finally replaced Imperial Korean police forces in June 1910, and they combined police forces and military police, firmly establishing the rule of military police. After the annexation, Akashi started to serve as the Chief of Police. These military police officers started to have great authority over Koreans. Not only Japanese but also Koreans served as police officers. In May 1910,
13680-522: Was held in The Hague . Emperor Gojong secretly sent three representatives to bring the problems of Korea to the world's attention. The three envoys, who questioned the legality of the protectorate convention, were refused access to the public debates by the international delegates. One of these representatives was missionary and historian Homer Hulbert . Out of despair, one of the Korean representatives, Yi Tjoune , committed suicide at The Hague. In response,
13800-452: Was incorporated. The committee supported the theory of a Japanese colony on the Korean Peninsula called Mimana , which, according to E. Taylor Atkins, is "among the most disputed issues in East Asian historiography." Japan executed the first modern archaeological excavations in Korea. The Japanese administration also relocated some artifacts; for instance, a stone monument (棕蟬縣神祠碑), which
13920-476: Was intended to preserve Korean historical artifacts, including those not yet unearthed. Japan's 1871 Edict for the Preservation of Antiquities and Old Items could not be automatically applied to Korea due to Japanese law, which required an imperial ordinance to apply the edict in Korea. The 1933 law to protect Korean cultural heritages was based on the Japanese 1871 edict. Due to a waterway construction permit, in
14040-525: Was obliged to become a Japanese protectorate by the Japan–Korea Treaty of 1905 and the "reforms" were enacted, including the reduction of the Korean Army from 20,000 to 1,000 men by disbanding all garrisons in the provinces, retaining only a single garrison in the precincts of Seoul. On 6 January 1905, Horace Allen, head of the American Legation in Seoul reported to his Secretary of State, John Hay, that
14160-434: Was officially legalized in 1906. Governor-General Terauchi Masatake facilitated settlement through land reform . The Korean land-ownership system featured absentee landlords, only partial owner-tenants and cultivators with traditional (but no legal proof of) ownership. By 1920, 90 percent of Korean land had proper ownership of Koreans. Terauchi's new Land Survey Bureau conducted cadastral surveys that established ownership on
14280-546: Was originally located in the Liaodong Peninsula , then under Japanese control , was taken out of its context and moved to Pyongyang . As of April 2020, 81,889 Korean cultural artifacts are in Japan. According to the Overseas Korean Cultural Heritage Foundation, not all the artifacts were moved illegally. Adding to the challenge of repatriating illegally exported Korean cultural properties is
14400-768: Was partially destroyed beginning in the 1910s, in order to make way for the Japanese General Government Building as well as the colonial Chōsen Industrial Exhibition . Hundreds of historic buildings in Deoksugung were also destroyed to make way for the Yi Royal Family Museum of Fine Art [ ko ] . The displays in the museum reportedly intentionally contrasted traditional Korean art with examples of modern Japanese art, in order to portray Japan as progressive and legitimize Japanese rule. The National Palace Museum of Korea , originally built as
