DN Tower 21, Protected office building in Yurakucho, Japan.
DN Tower 21 rises to 99.8 meters with 24 floors, featuring a granite exterior design that combines modern architecture with historical elements.
The original structure served as General MacArthur's headquarters during the post-World War II occupation of Japan by Allied Forces in the 1950s.
The building preserves sections of the original Dai-Ichi Seimei Kan and Norinchukin Bank structures, reflecting Tokyo's architectural preservation practices.
The building stands directly accessible through underground passages from Hibiya Station's B2 exit and Yurakucho Station's D1 exit.
The structure maintains MacArthur's former office space within its walls, though this historical section remains closed to general public access.
