The M24 (Japan) was, together with the M4A3 (76) W, provided by the Americans to the Japanese to rebuild Japan's military in self defense due to the outbreak of the Korean war. Generally liked by its new Japanese crews, the Chaffee was rather inadequate for its service time within the JGSDF, only offering a short barrel 75 mm, it was already outdated facing tanks such as the T-34-85.

It was introduced along with the initial Japanese Ground Forces tree in Update 1.65 "Way of the Samurai". This Japanese vehicle is identical to the American M24 Chaffee. Facing relatively low ranking opponents, the M24 can be used to peak performance playing as a nimble light tank, with the firepower of Sherman 75s. Packing the very competent M61 APCBC shell, smoke grenades, .50 cal MG, very forgiving reverse speed, and scout abilities, the M24 is a very versatile tank capable of outflanking and combating most tanks it faces.
