Tokyo is the capital of Japan and the largest city in the world by population, with over 37 million people in the greater Tokyo area.

During the Edo period, which lasted from the 17th to the mid-19th century, Japan was ruled by the Tokugawa shogunate and experienced a period of peace and stability.

Japan has a game show called "Human Tetris" where contestants have to contort their bodies to fit through holes in a moving wall.
