If you are talking about Ki-84
Hayates in Japanese Army Air Force Service then POSSIBLY subject to confirmation in the JAAF unit's
(104
Hiko sentai) Sento KodoShoho (daily combat reports). These records are often missing fom the late war period (post June 1945) as the war situation precluded them from being returned to Army HQ archives in Japan.

Hiko sentai Ki-84
Hayates at Tokorozawa airfield after the surrender.
However, if you include Ki-84 captured and taken over by the
People's Liberation Army Air Force (PLAAF), also referred to as the
Chinese Air Force (CAF) then definitely but, encounters with Soviet Red Army AF A/c can't be confirmed as CAF records from post WWII period are non-existant.
The photo record is clear as there are many pics of captured Ki-84
Hayates with PLAAF/CAF markings in the Hankow, Peking and Manchuria areas.

Either way, without Soviet Red Army AF records of such encounters, it's going to be very difficult to confirm such interceptions did occur post WWII. Maybe Shinpachi can find proof in the vast repository of WWII records that is JAYCAR.
