I've sifted through the USSBS "corporation reports" for different Japanese companies, and one thing looks amiss - the production numbers of the N1K Kyofu (a.k.a. Rex), the floatplane fighter. The Nakajima report notes, on pg. 85, that 323 of those were assembled on the company's Koizumi plant (plant manufacturing/assembling the Navy aircraft), however Kyofu's numbers are missing from the monthly recapitulations that are on pages 40-42. Japanese Wikipedia notes only 97 or the Kyofus manufactured (just Kawanisnhi's production?).
