Design and development

The excellent characteristics of the Tachikawa Ki-36 made it potentially ideal as a trainer. This led to the development of the Ki-36 with a single machine-gun. After successful testing of a prototype in September 1939, the type was put into production as the Army Type 99 Advanced Trainer.

In all 1,389 were constructed before production ended in December 1943 with Tachikawa having built 1078 and Kawasaki 311.

Both the Ki-55 and the Ki-36 were given the Allied nickname 'Ida.'
