Marunouchi is an area in Chiyoda, Tokyo, Japan, located between Tokyo Station and the Imperial Palace. The name, meaning "inside the circle", derives from its location within the palace's outer moat. Marunouchi is the core of Tokyo's central business district as well as one of the main financial centres in Japan. 20 of the Fortune Global 500 companies are headquartered in the area as of 2021, while many other such companies based outside Japan have Asian or Japanese offices there. Together with the neighbouring districts of Yūrakuchō and Ōtemachi, Marunouchi is part of a larger business district sometimes referred to as Daimaruyū.
