It was designed by Shinichiro Okada and completed in March 1934. The building was one of the first of its kind to be completely designed by Japanese architects, executed by craftsmen and material coming from Japan, as opposed to earlier western-style buildings. This was accomplished just over 60 years after the end of the feudal Edo period and the opening of the country.
During the Sh?wa period, its metal fittings were requisitioned by the government of Japan. It survived the bombing of Tokyo during World War II, but was taken over by the General Headquarters / Supreme Commander for the Allied Powers (GHQ/SCAP) after the war. It was returned to the government of Japan in 1956. In 1997, this building was designated a National Important Cultural Property. It was the first building erected in the Showa period to receive this honour.
