Japanese Flight Suit Identification

[Herk1994]

Hello,

Looking to identify this flight suit. So far I don’t have much, doesn’t seem to be much for material out there on Japanese WW2 era flying uniforms aside from the electric heat extreme cold weather examples.

My best idea thus far is that it is an IJN flight suit, cold weather, but not necessarily an extreme cold weather flight suit. It doesn’t have provisions for electrical heating, nor did it ever as best I can tell.

It looks to be unissued, but unfortunately some joker made some art on the patch. Also, a belt loop has broken on the back side. Otherwise a decent flight suit with intact collar fur lining.
