A variety of types in the videos today but mainly "Raiden".
Here are some stills from the clip.
More "Raiden" in the next video.
Unfortunately I have difficulty identifying the type of the aircraft below. Any ideas?
From your comments it's identified as a Watanabe K10W1, tail number "81-634" (thanks guys). This means it belonged to the 1081Ku which was organized on April 1, 1944, in Atsugi. A transport unit that merged with the 1021Ku on July 16, 1945. The first marking was "ヨE" which was used until September 1944. Then the number "81" was used and often a swallow. You can see it painted on the tail of a "Nell" in a still further above.
More videos of different types of aircraft. Note the line-up of the "Raiden" without markings and the L2D.
A quite interesting color video. I'm not sure of the unit of the "Tenzan" at the moment.
I thought to bring the part with the "Ginga" prototype here together with some stills.
And finally a beautiful "Raiden" video via Jacob Terlouw. note that they still have their wing cannons!
