Imperial Diet Building

The National Diet Building (国会議事堂^?, Kokkai-gijidō) is the building where both houses of the National Diet of Japan meet. It is located at 1-chome, Nagatachō, Chiyoda, Tokyo.

Sessions of the House of Representatives take place in the left wing and sessions of the House of Councillors in the right wing.

The Diet Building was completed in 1936 and is constructed out of purely Japanese materials, with the exception of the stained glass, door locks, and pneumatic tube system.

The construction of the building for the old Imperial Diet began in 1920; however, plans for the building date back to the late 1880s. The Diet met in temporary structures for the first fifty years of its existence because there was no agreement over what form its building should take.

German architects Wilhelm Böckmann and Hermann Ende were invited to Tokyo in 1886 and 1887, respectively. They drew up two plans for a Diet building. Böckmann's initial plan was a masonry structure with a dome and flanking wings, similar to other legislatures of the era, which would form the core of a large "government ring" south of the Imperial Palace. However, at the time there was public resistance in Japan to Foreign Minister Inoue Kaoru's internationalist policies, and so the architects submitted a more "Japanese" design as well, substituting traditional Japanese architectural features for many parts of the building. Ende and Böckmann's Diet Building was never built, but their other "government ring" designs were used for the Tokyo District Court and Ministry of Justice buildings.
