National Diet Building
The original Sanno Hotel opened in 1932 on the southern side of Hie Shrine in Nagatachō, Tokyo, neighboring Akasaka, near the Imperial Palace and National Diet Building. The privately owned hotel, with a Western design, was considered one of the top three accommodations in Tokyo along with the Imperial Hotel and the Dai-chi Hotel, and was frequented by government and military officials. The hotel served as the headquarters for dissident military units during the February 26 Incident in 1936.
