- The Shiden Kai 4 is a carrier-based fighter developed from the Shiden Model 32 Shiden Kai 3. It was equipped with a Homare Model 23 (N9KH-S) engine, armed with two Type 3 Model 1 nose-mounted 13.2 mm machine guns and four Type 99 wing-mounted 20 mm machine guns; arresting gear was also installed. One prototype was built at Kawanishi's Naruo plant.
- The tail code written on the aircraft is ク-521, the Kana character identifies the plane as part of the Kure Naval Air Group.
- The Kure Naval Air Group mainly operated seaplanes aboard Japanese warships and Zero fighter detachments of the Iwakuni Naval Air Group, meaning that the Kawanishi fighter does not bear any connection to the Kure Naval Air Group.
