The Type 5 Na-To ( Experimental 7.5cm self-propelled anti-tank gun Na-To) was the penultimate tank destroyer developed by the Imperial Japanese Army in 1945, during the closing stages of World War II. It was intended to become part of the defenses of the Japanese home islands against the projected Allied Invasion, only two units were completed by the surrender of Japan. Neither one was used in combat.
