Designs of this assault tank destroyer used the Chi-To medium tank as a base. The suspension made it possible to mount powerful artillery systems, such as the 10 cm Cannon Type 92 gun, capable of fighting against most vehicles of that time. The gun was mounted in a fully closed fighting compartment with anti-projectile armor, but the basic chassis remained virtually unchanged. Due to the unreliability of the vehicle, as well as the existence of the more promising Chi-Ri suspension, the project was canceled at the drafting stage.
