The Ki-17 "Cedar" biplane trainer was designed to replace the unsatisfactory Ki-9 "Spruce". Unlike the earlier design, it did not try to fulfill the roles of both primary and secondary trainer, but was exclusively a primary trainer. This meant that it could be designed to a 6 g stress rather than the 12 g of the Ki-9. The result was an unusually light biplane that was rushed into production in 1935 to train the large number of pilots required to expand the Army aviation program.
