Perhaps you've seen these videos before, perhaps you haven't. In any case, here they are.
I found them on YouTube, HERE, and the source as they explain is the ROMANO-ARCHIVES'.
And here's the link one more time: https://www.youtube.com/watch?v=f2lgrnMIMAk

Let's see some interesting stills.
A Mitsubishi Ki-51 "Sonia". Note the gun camera mount on the wing.Another "Sonia" of an unknown unit.
"Sonia" and Tachikawa Ki-36 "Ida"
"Sonia" canopy and cockpit
And a surprise; a Mitsubishi Ki-109. This video was taken at the Kurume airfield, Fukuoka prefecture. The particular type was used from that airfield to escort ships travelling between Shimonoseki and Busan in Korea. It was designed as an interceptor but the performance left much to be desired so most of them were set aside to be used in attacks against the Japan mainland invasion fleet.
These two stills below show the tail gun of a "Hiryu", perhaps the tail of the above Ki-109.
