B29 automated .50 cal rounds would auto-eject rounds with soft primer strikes. Lots of "live" .50 cal. ammo over Japan....even more brass ;)
I have three BMG .50 shells I found on a mountain in Tokyo. The head stamps are De Moines ‘44 and ‘45. Pretty awesome, eh? Real relics with real history. I still can’t figure out why they were on the ground though, or where they came from.
I mean shell casings.
My guess would be from an American airplane.
Maybe strafing a target or a bomber defending itself or a fighter trying to shoot down a Japanese plane.
An airplane?

WWII era fighters ejected spent casings upon firing, usually through ports in the underside of the wings. BMG .50 was pretty much the standard gun on fighters that would have seen any action over Japan.
THAT is cool! Those are quite possibly the spent casings from American aircraft fighting over that area.
