Kawasaki Ki-100-I (low back type)

With the Ki-100 proving such a success, it was decided to initiate production of this aircraft, the resulting Ki-100-Ib differing only by having the cutdown rear fuselage and all-round-view canopy that had been designed for the proposed Ki-61-III.

4 decal variants:

1. Ki-100, Akeno Flight Training Division (111th Air Regiment, flown by Mj. Yohei Hinoki (12 victories, Miki AF, Hyougo prefecture Japan, July 1945

2. Ki-100, 5th Air Regiment, Kiyosu AF, Aichi prefecture, Japan, July 1945

3. Ki-100, 244th Air Regiment, flown by Regiment Commander Maj. Teruhiko Kobayashi (12 victories), Yokaichi AF, Shiga prefecture, Japan, July 1945

4. Ki-100, 244th Air Regiment, flown by Regiment Commander Maj. Teruhiko Kobayashi (12 victories), Yokaichi AF, Shiga prefecture, Japan, July 1945

A total of 99 of this version was built before production was brought to an end by the growing weight of USAAF air attacks. A more effective version had been planned, to be powered by the Mitsubishi Ha-112 engine which incorporated a turbocharger to improve high-altitude performance, but only three of these Ki-100-II prototypes had been built and flown by the end of the war.
