The seaplane also served as an interceptor for protecting fueling depots in Balikpapan and Avon Bases (Dutch East Indies) and reinforced the Shumushu base (North Kuriles) in the same period. Such fighters served aboard seaplane carriers "Kamikawa Maru" in the Solomons and Kuriles areas and aboard Japanese raiders Hokoku Maru and Aikoku Maru in Indian Ocean raids. In the Aleutian Campaign this fighter engaged with RCAF Curtiss P-40 Warhawk, Lockheed P-38 Lightning fighters and Boeing B-17 Flying Fortress bombers. The aircraft was used for interceptor, fighter-bomber, and short reconnaissance support for amphibious landings, among other uses.
