Armament. Two 20mm Ho-5 cannons and one 37mm Ho-204 cannon, light bombs.
Structurally, the Ki-98 fighter was a single-engine fighter with a two-blade pusher propeller.
The power plant is a radial 18-cylinder air-cooled Mitsubishi Na-211-III engine mounted in the fuselage behind the cockpit. A four-bladed pusher propeller located at the end of the central nacelle was driven by a two-meter shaft. To improve the aerodynamic properties for engine cooling, the designer abandoned the standard air intakes, using the original "gills" located behind the cockpit in the upper part of the fuselage-nacelle. To increase the air flow to the engine, it was equipped with a fan, also driven by the engine, but located in front of it. The cooling air passages ended behind the engine, just in front of the propeller, with a series of small nozzles. A wing with a profile close to laminar was located in the lower part of the fuselage, from each half-wing there was a long thin tail boom with keel washers at the end and with a stabilizer between them.
The aircraft used a three-wheeled landing gear with a front support, which was retracted back into a niche under the cockpit, the main struts were retracted inside the tail booms. Since the cockpit was high enough above the ground, access to the cockpit was through the niche of the front landing gear. In the event of an emergency exit from the plane, the pilot had two options to choose from. He could get out traditionally through a drop-off canopy to almost guaranteed to get into the plane of the propeller. Mansyu recommended a second escape route, through a hatch at the bottom of the aircraft. This allowed the pilot to avoid a collision with the stabilizer, and somewhat increased the chances of not being hit by the propeller.
A drop-shaped cockpit canopy provided excellent visibility in all directions. The armament was supposed to be very powerful, two 20-mm No-5 cannons and one 37-mm No-204 cannon. All the guns were concentrated in the bow of the central nacelle, with the barrels protruding strongly forward due to the relatively short fuselage-nacelle and lack of space.
