Parliamentary Museum, Parliamentary museum in Nagatachō, Tokyo, Japan.
The Parliamentary Museum is a building in Nagatachō, Tokyo, that presents the development of Japanese democracy through papers, images, and digital displays. Exhibition spaces offer insight into how both chambers of the National Diet work and the constitutional foundations of the country.
The building opened in March 1972 on the occasion of the 80th anniversary of parliamentarism in Japan. Its establishment marked a commitment to preserve and pass on the memory of constitutional government.
The name reflects its mission to make parliamentary history accessible to visitors of all ages. School groups often visit the rooms here to learn more about lawmaking and their own role as citizens.
