On which island is Tokyo located?

Tokyo is the capital and most populous prefecture of Japan. Located at the head of Tokyo Bay, the prefecture forms part of the Kantō region on the central Pacific coast of Japan's main island of Honshu.

The island separates the Sea of Japan, which lies to its north and west, from the North Pacific Ocean to the south and east. It is the 7th largest island in the world and the 2nd most populous after the Indonesian island of Java.

Tokyo is the political and economic center of the country, as well as the seat of the Emperor of Japan and the national government. In 2019, the prefecture had an estimated population of 13,929,280. The Greater Tokyo Area is the most populous metropolitan area in the world, with more than 37.393 million residents as of 2020.

Most of Japan's industry is located in a belt running along Honshu's southern coast, from Tokyo to Nagoya, Kyōto, Osaka, Kobe, and Hiroshima; by contrast, the economy along the northwestern Sea of Japan coast is largely based on fishing and agriculture. The island is linked to the other three major Japanese islands by a number of bridges and tunnels. Its climate is humid and mild.
