We have originally posted the first video today, a few years back, HERE, with information about the 23rd Dokuritsu Hiko Chutai Kawasaki Ki-61 "Hien".
Below is a still from the video and a color photo often found on the net.
I also found a photo of another "Hien" from the same unit from this site.
Which has another photo of yet another "Hien" from the same unit. You can clearly see that the camouflage patterns are completely different on all three aircraft (please ignore the horribly inaccurate color profile).
There is also a photo of the "Sonia" seen in both videos, but the tail area is too dark and I can't make out any tail marking. If you know of a clearer version of the photo, email or leave a comment.
The second video today, from here, is of rather poor quality.
But we can still make out first the 763-62 "Ginga" tail we saw in the previous post...
...an unidentified bomber, maybe a "Sally"...
...and the "YO" "Hayabusa" with the 55 Sentai "Hien" from the previous posting. On the left side under the wing, there is an object that looks like a drop tank. If that's the case then this is not a tokko "Hayabusa" but rather an escort.
