Greg - Thanks. Lieutenant Hinoki Yohei commanded 3/64 Chūtai from May to December 1943 when the unit was based at Mingaladon and Sungei Patani, Burma (according to Ikuhiko Hata, Yasuho Izawa, and Christopher Shores, Japanese Army Air Force Fighter Units and Their Aces 1931-1945, London: Grub Street, 2002, pp. 157, 159).

Gary - Captain Katō Tateo commanded the 1st Squadron of the 2nd Flying Battalion (Hikō Daitai) in Manchuria from July 1937 to May 1938. In August 1938, the 2nd Flying Battalion and the 9th Independent Flying Company (Dokoritsu Hikō Chūtai) were merged to form the 64th Flying Regiment. Now-Major (posthumously Lieutenant Colonel) Katō commanded the 64th from April 1941 to May 1942. The 64th received Ki-43s in September 1941 while the unit was based in China. Katō commanded the unit during the fighting in Sumatra, Malaya, and Burma until he was killed (as you know) on 22 May 1942 in action against Bristol Blenheims of No. 60 Squadron RAF over the Bay of Bengal. In 1944, a film was made about his life: Kato Hayabusa Sento-tai (Kato's Peregrine Falcon Squadron): https://www.imdb.com/title/tt0036980/
