Fuji refitted a KM-2 with an Allison Model 250 turboprop engine in place of the original Lycoming piston engine, the resulting KM-2D first flying on 28 June 1984 [1] and being certified on 14 February 1985.

[1][2] The KM-2Kai is a further development of the KM-2D, with a modernised cockpit with side-by-side seating and a sliding canopy replacing the original KM-2's car type side doors [2] (which were retained by the KM-2D[1]).

The T-5 is an all-metal low-wing cantilever monoplane powered by an Allison 250-B17D turboprop with a three-bladed constant speed propeller.

The KM-2Kai was ordered by the JMSDF as the T-5 in March 1987,[2] with deliveries of the KM2-Kai to the Japanese Self Defence Forces beginning in 1988, with a total of 40 being built.
