The Howa Type 89 was a replacement for the Japanese Self-Defense Force’s Howa Type 64 rifle. As with many other major militaries, the JSDF made the transition from a .30 caliber, wood stocked, milled receiver rifle to a .22 caliber, stamped construction weapon. The Type 89 was largely based on the AR18 design, with a stamped receiver and gas piston action. Most used a fixed polymer stock, though our photos show the folding-stocked variant.
