Prime Minister's Residential Area

The Prime Minister's Residential Area is a government building in Nagatachō and consists of three floors above ground plus one basement level made of reinforced concrete. The building combines living quarters with working spaces and covers an area of roughly 5,200 square meters (about 56,000 square feet).

The building was completed in 1929 as part of the reconstruction program following the Great Kantō Earthquake of 1923. Architect Muraji Shimomoto designed the structure with references to Frank Lloyd Wright and shaped an independent vision for the complex.

The name comes from the political function of the district and the rooms serve today for meetings with visitors and delegations from home and abroad. The design of the reception rooms follows Japanese traditions and displays works by contemporary artists from the country.

The complex is not open to the public and can only be viewed from the outside. Visitors to the district will find other government buildings nearby and can get a sense of Japan's administrative structure.

An underground passage connects the residence with the official office building and allows direct routes between working areas. This structural solution was created for security reasons and simplifies daily routines for the occupants considerably.
