Also from Skyraider's 3D site;
the Kugisho high-speed fighter study with Daimler-Benz DB 601
inline engine of the 1939.

Attached are the original drawings for these fighter studies. There was a radial-powered version as well. The inline version has an imported DB 601, by the way.
As you can see I took the liberty to add weapons and cooling features, which aren't in the drawings, but are based on existing practises with the Me 109 and Zero.
The radial engine variant is peculiar as it doesn't appear to have an air intake! I suspect this was an early study of what would finally become the J2M and/or N1K1, i.e. with big radials and big spinners.
