is a Japanese organization of retired military servicemen whose membership is open to former commissioned officers of the JASDF and JGSDF as well as commissioned officers, warrant officers, officer cadets, and high-ranking civil servants who served in the Imperial Japanese Army. Since 1 February 2011 Kaikosha has been a non-profit organization described under Japanese law as a public interest foundation .
The original Kaikosha was founded before World War II as an organization exclusively of active-duty commissioned officers and warrant officers in the Imperial Japanese Army for mutual aid, friendship, and academic research, but was re-founded after the war to represent formerly high-ranking army officials.
The organization’s name means “let’s go together” or “we shall fight this war side by side,” and derives from a line in an old Chinese poem recorded in the Book of Odes.
