The first Type 5 fighters (Ki-100-Ia) were direct conversions of existing Ki-61-II airframes. 271 airframes were converted between March and June 1945, and were immediately delivered to operational units.
The Ki-100 was simple to fly and maintain. Even the most inexperienced pilots were able to get the hang of the Ki-100 relatively quickly. The Ha-112 engine proved to be quite reliable and simple to maintain. In combat, the Ki-100-Ia proved to be an excellent fighter, especially at low altitudes. It possessed a definite ascendancy over the Grumman F6F Hellcat. In one encounter over Okinawa, a Ki-100-equipped unit destroyed 14 F6F Hellcat fighters without loss to themselves. When the Ki-100 encountered the P-51D Mustang at low or medium altitudes over Japan, it was able to meet the American fighter on more or less equal terms. The outcome of P- 51D vs Ki-100 battles was usually determined by piloting skill or by numerical advantage rather than by the relative merits of the two fighter types. However, at altitudes above 26,000 feet, the maneuverability of the Ki-100 began to fall off rather severely and the fighter was at a relative disadvantage in intercepting the high-flying B-29.
So far as I am aware, the Ki-100 never had a separate Allied code name assigned to it. It may, for all I know, have been known under the code name of its predecessor --- TONY.
