French or Japanese? They didn't do tanks well.
Please - the French Renault FT, forerunner of all modern tanks, the first one to have the driver in front, engine in back, and main armament in a 360 degree rotating turret. Last in service as a pillbox/machine gun post in the Soviet/Afghan War of the 1980’s, some reports of its use in the Iraq war of the 2000’s - over a half century of service, at least.
This one is in a Belgian museum, others saw service in Europe, the Middle East, Asia, the South Seas, and America.
