Today's video in color (!) of admittedly not so good quality features a variety of interesting IJAAF types. The video from HERE, starts with a Nakajima Ki-55 "Ida", the cockpit of which can be seen at 00:20. Then we can see an interesting Mitsubishi Ki-51 "Sonia" belonging to an unknown unit. After a variety of closeups and wide-shots, the cameraman chose to show us, at 53:00, a very rare shot of a Mitsubishi Ki-109 followed by not that clear shot of the cockpit and much better views of the tail machine gun.
There are two NARA photos taken at the same place and at the same time. According to the NARA caption, the location is the airfield of Kurume, Fukuoka Prefecture.
In this wide shot we can see various Mitsubishi Ki-51 "Sonia" and Tachikawa Ki-36 "Ida" and/or Tachikawa Ki-55 trainers. The "Sonia" sport a variety of tail markings of un-identified units, but most probably belonging to tokko groups.
