The Joint Staff Office (Japanese: 統合幕僚監部, Tōgō bakuryō-kanbu: abbreviation: JSO), also known as the Joint Staff and formerly known as the Joint Staff Council, is one of the administrative agencies within the Government of Japan. It is a special organisation under the Japanese Ministry of Defense responsible for integrating the military operations of the Ground, Maritime and Air Self-Defense Forces. The abbreviation of the agency in Japanese is Tōbaku (統幕).
