Dai-ichi Life Hibiya First
Dai-ichi Life Hibiya First, known from 1995 to 2022 as DN Tower 21 (for Dai-ichi and Norinchukin), is an office high-rise in Tokyo, Japan. It was erected in 1988-1995 on the site of the respective former head office buildings of Dai-ichi Life and Norinchukin Bank, both designed by architect Jin Watanabe and completed in 1938 and 1933 respectively.
The site is historically significant for having hosted Douglas MacArthur and his staff as Supreme Commander for the Allied Powers (SCAP) during the occupation of Japan following World War II.
Norinchukin Bank left the building in early 2022. The building was consequently rebranded and remains the head office of Dai-Ichi Life.
