Central Tokyo’s only large, Western-style park, Hibiya Park is the focus of Hibiya district. Its location, east of the political centers of Kasumigaseki and the Diet Building, makes it a favorite place for protests, especially on May Day. The large bandstand is occasionally used for concerts.
Completed in 1936, the Diet Building houses the legislature of the Japanese government, originally established as the Imperial Diet in the Meiji era. Tours (in Japanese only) cover the well-worn inside, including the diet chamber, where you can see the deliberations of diet members, and the extravagantly decorated rooms used by the emperor for official functions
