Many thanks to both senior members, Zdenek and Michel
According to Nicholas Millman the 70th were still flying the Ki44 Shoki at EOW, as evidenced in Millman's "Ki-44 Tojo aces of WW2" where he
seems to state that Honda was flying one when he was killed on 10 August 1945. Sakaida and Koji Takaji in "B-29 Hunters of the JAAF" state that it had swapped these for Ki-84 cJuly 1945 and that the 18th Sentai had at least some Ki-100. I see from JAAF Aces (Hata, Izawa and Shores) that the 1st flew Ki84 from 1944 to EOW but they indicate the 18th had it's last Ki61 in the unit in June 1945, having been progressively re-equipped with Ki-100 from March 1945. According to this source the 70th had a mix of Ki44/Ki84 from June 1945 until EOW.
On 10 August 1945 Moore claimed to have damaged a Ki100 and an Oscar, and to have destroyed a Tojo. I assume the "Oscar" was a mistaken "Frank"?
On this date 1Lt Bill Farrell claimed a "Tony" so Ikeda might have been his victim.
