History
The Kanto plain has been settled since the Jomon era, whose shell mounds dot the old shores of Tokyo Bay, but it long lay far from the court at Nara and Kyoto. Its warriors made it the centre of power: in 1192 Minamoto no Yoritomo became shogun and ruled from Kamakura, where his regime and the Hojo regents lasted until 1333. In 1457 the warrior Ota Dokan built a castle at the fishing village of Edo.
In 1590 Tokugawa Ieyasu received the Kanto as his domain and made Edo his base; after he became shogun in 1603 it grew into one of the largest cities in the world, with around a million people by the 18th century. His grandson Iemitsu rebuilt the Toshogu at Nikko as Ieyasu's lavish mausoleum. In 1853 Commodore Perry's ships anchored off Uraga at the mouth of Edo Bay, and in 1859 Yokohama opened as a treaty port. In 1868 the emperor moved to Edo, which was renamed Tokyo, and in 1872 Japan's first railway linked the capital with Yokohama.
The 20th century twice levelled the city: the Great Kanto earthquake of 1923 and the fires that followed killed more than 100,000 people, and American firebombing in March 1945 killed about as many again in a single night. Tokyo rebuilt to host the 1964 Olympics, opening the first Shinkansen that year, and the metropolis spread across the plain in the decades of growth that followed. It hosted the Olympics again in 2021, a year late because of the pandemic.
