The Tony was the only Japanese fighter that could have the firepower of a heavy twin engine interceptor vs B-29s and also defend itself vs the fighter escort by virtue of a motor-cannon. The Bf 109 and many other WW2 fighters utilized this advantage. An inline engine was a prerequisite. This eliminates all other Japanese fighters due to their radial engines. So, why didn't the Tony pack a hub-cannon? It was the only interceptor of B-29s built for high altitude with the 1944 Ki 61-II. So, it could use the added firepower.
