Data from Hiroshi Takagi, both from his website ([]) and personal communication August 2000.
Information from Ejii Nozawa's web site ([]) says that Hitachi, Kawasaki, KSK, Mitsubishi, and Nippon supplied these engines to Taiwan from 1940 to 1951, probably from the overall total of 1,115 built for Japan during World War II.
