Altogether 246 concerts were performed, but the event was discontinued when its popularity waned and the last concert took place in November 2000. The event returned in 2004 as the "Aka Renga (Red Brick) Concerts" but it was again suspended, after 19 concerts, when redevelopment of

392-631: A central lagoon . Important human migrations occurred in the Pacific in prehistoric times. Modern humans first reached the western Pacific in the Paleolithic , at around 60,000 to 70,000 years ago. Originating from a southern coastal human migration out of Africa, they reached East Asia , Mainland Southeast Asia , the Philippines, New Guinea , and then Australia by making the sea crossing of at least 80 kilometres (50 mi) between Sundaland and Sahul . It

490-524: A new station on this line called Central Station ( 中央停車場 , Chūō Teishajō ) , located directly in front of the gardens of the Imperial Palace. Construction was delayed by the outbreak of the First Sino-Japanese War and Russo-Japanese War , but finally commenced in 1908. The three-story station building was designed by architect Tatsuno Kingo (who also designed Manseibashi Station and

The middle reaches of the Isumi River provide irrigation for extensive paddy fields for rice production in Isumi. The area also produces tomatoes and cucumbers . The economy is supplemented by the summer tourist traffic to the local beach resorts. The border between Ichinomiya and Isumi City starts at

1274-491: Is not known with any certainty what level of maritime technology was used by these groups – the presumption is that they used large bamboo rafts which may have been equipped with some sort of sail. The reduction in favourable winds for a crossing to Sahul after 58,000 B.P. fits with the dating of the settlement of Australia, with no later migrations in the prehistoric period. The seafaring abilities of pre-Austronesian residents of Island South-east Asia are confirmed by

Over the same fiscal year, the Tokyo Metro station was used by an average of 218,275 passengers daily (both exiting and entering passengers), making it the ninth-busiest Tokyo Metro station. The passenger figures (boarding passengers only) for the JR East (formerly JNR) station in previous years are as shown below. Other stations within walking distance of Tokyo station include

9016-786: The tropics and Antarctica, which records the coldest temperature readings on the planet. In the Southern hemisphere, because of the stormy and cloudy conditions associated with extratropical cyclones riding the jet stream, it is usual to refer to the Westerlies as the Roaring Forties, Furious Fifties and Shrieking Sixties according to the varying degrees of latitude. The ocean was first mapped by Abraham Ortelius ; he called it Maris Pacifici following Ferdinand Magellan 's description of it as "a pacific sea" during his circumnavigation from 1519 to 1522. To Magellan, it seemed much more calm (pacific) than
