I stumbled across a photo of a Japanese Mitsubishi KI-67 Hiryu/Peggy on the links below. I was struck by the unusual squadron markings as well as what appears to be nose art?
The photo is very slightly touched up to remove scratches & blemishes from it I was to find out later.
That is all that was done though what you see is what is there.

http://www.flickr.com/photos/keleivis/6011583321/in/photostream/His father was in Japan & he believes his dad took the photos at Tachikawa Air Base.
Now I sent these links off to a researcher who has a lot of good contacts with Japanese artists & historians & they came up with this profile.

I have contacted one individual who has helped me & the belief is that this aircraft was attached to one of the very first units to use the KI-67's. At this point in time the unit is unknown.
The grey colour interestingly enough is correct

I guess the early ones were painted in this manner?
The nose art is interesting too because I believe it is Chinese & not Japanese.
至誠 English word is.... (zhicheng). Translation I think is (If there is a will there is a way.)
Not sure if I have all my facts right as I can't speak Japanese & the contacts are not that strong on English either.
On line translating gives me about three different answers depending on what one you use so I hope I am in the ball park on this.
I just got some Japanese magazines today that I am about to look through on KI-67's so maybe there is more to be found there.
Any help on this would be great Thanks.
