Yep, the Oscar was one of the most produced Japanese planes during the war. It's right up there with the He-111/Do-17, Yak-1/3, Pe-2, Betty, A-26 needs. PLUS the reworking to the new AHII standards: B-26, C-47, P-40B/E, SBD-5,TBM,Hurricanes, Boston/A-20, Mosquito, Lancaster, Ar-234, Bf-110's, C202&205, A6M2/5b, B5N2, D3A1, Ki-61, Ki-67, and the Yak9's. Now, throw in adding more WWI features and aircraft.
Ya know what would be nice? A roadmap of their development plans so it can help us understand where they're going...
