Hino Motor Company and Mitsubishi competed with their designs for a tank that was to replace the Type 95 Ha-Go.3 The Hiro design proved to have better cross country capabilities and was selected to become the Type 98 Ke-Ni.3
One of the tanks designers was General Hara.4
Driver was positioned in front in the center and had steering wheel control.

Type 2 Ke-To
Hino changed the Type 98 Light Tank to have a 37 mm Type 1 gun in a roomier turret.3 This became the Type 2 Ke-To.3
The Type 98 Ke-Ni wasn't produced in great quantities as there were difficulties retooling the factories and the overall need for light tanks had diminished.4 The Japanese Army delayed the production until 1942 as it felt that the Type 98 wasn't needed anymore.3
