The Ichigaya Memorial Hall is a historical architectural site located near the Yako-ji Gate within the Ministry of Defense grounds in Shinjuku, Tokyo. This facility is a relocated and restored portion of the former 'Building No. 1.' It preserves the architectural style of the building that served as the Imperial Japanese Army Academy headquarters in 1937 (Showa 12). The structure serves as a physical testament to crucial moments in modern Japanese history, having functioned as the Ministry of War, the Imperial General Staff, and the site of the Great Hall used during the International Military Tribunal for the Far East.
The history of this site begins with the era of the Imperial Japanese Army Academy. Originally constructed as the headquarters for the Academy, it later served as the headquarters for the Army Preparatory School. During the Pacific War, it became a central hub housing the Ministry of War and the Imperial General Staff. Furthermore, it holds the historical significance of being the venue for the International Military Tribunal for the Far East. From the 1960s, it was used by the Eastern Army of the Japan Ground Self-Defense Force and was also the site of the Mishima Incident in 1970. While the original structures were demolished due to the construction of the new Ministry of Defense building, vital sections—including the 'Benden-no-ma' (used during Imperial visits) and the 'Principal's Office' (formerly the Army Minister's office)—were relocated and restored to their current location in 1998.
The facility preserves fragments of significant historical architecture. Notable features include the Great Hall, which conveys the grandeur of the former Imperial Japanese Army Academy, and the architectural structures used for historical ceremonies. The relocated 'Benden-no-ma' and 'Principal's Office' serve as precious resources that demonstrate the specific architectural styles and functions of that era. These spaces represent a point where Japan's military and political histories intersected.
The Ichigaya Memorial Hall is open as part of the 'Ichigaya-dai Tour' conducted by the Ministry of Defense. Visits are strictly based on the tour schedule. The primary visiting hours are during the daytime on weekdays (from 9:00 AM to 4:00 PM). While the outdoor architectural scenery is not heavily affected by weather, it is essential to check the tour reservation status before visiting.
General visitors can explore parts of the Ichigaya area, including this memorial hall, by participating in the official 'Ichigaya-dai Tour' organized by the Ministry of Defense. This program goes beyond simple architectural viewing, offering a deeper understanding of Japan's defense and history. It provides a rare opportunity to witness the structural layout of spaces that retain the atmosphere of the former Imperial Japanese Army Academy.
The facility is located within the Ministry of Defense grounds, surrounded by a memorial zone dedicated to fallen members of the Self-Defense Forces. This area includes monuments for those who served in the National Police Reserve and the various branches of the Ground, Maritime, and Air Self-Defense Forces. Within the premises, there are also retail and dining options such as convenience stores (FamilyMart, Seven-Eleven) and cafes (Doutor Coffee Shop) located in the welfare building.
Due to the nature of the Ministry of Defense grounds, security is strictly managed. The main gate is guarded 24 hours a day by civilian security and Self-Defense Force personnel, and some areas may involve armed guards. Please note the following:
