The Chamber of the House of Representatives in the National Diet Building, located in Tokyo, Japan, is a significant and impressive space where legislative activities take place. This chamber is characterized by its large, semicircular arrangement of seats, designed to facilitate debate and discussion among the representatives. The interior features a blend of traditional Japanese and Western architectural elements, with a prominent central podium and a gallery for public viewing. The chamber's design emphasizes transparency and democracy, highlighted by the use of natural light and symbolic decorative elements. As the primary venue for Japan's legislative process, it holds a pivotal role in the country's political landscape.

National Diet

Roppongi, Akasaka & Around

Free one-hour tours of parts of Japan's parliament building and grounds are available when the Diet is not in session (ring the day before to confirm). The tours take in the public gallery, the emperor’s room (from where he addresses the Diet at the start of each session) and the central hall, which features a floor mosaic of a million pieces of marble, and murals depicting the four seasons.

Built on a site once inhabited by feudal lords, the National Diet was completed in 1936 and houses two chambers – the Shūgi-in (House of Representatives; the Lower House) and the Sangi-in (House of Councillors; the Upper House).

An English pamphlet is available if there's no English-speaking guide when you arrive. Visit in the afternoon to avoid being tacked onto the larger tour groups.
