Youth Group's flag, Shirotori Village, Ōkawa County
It's definitely original. I use to have a similar one. Here is an old photo of it with some helmets. Same size and with orange tassels. They are of very good quality. Although mine was a veteran's flag.
So a very expensive Boy Scout flag. Looks great, but non military is a non buy for me.
I don't know the group referred to with this particular flag nor it's date but given the Rising Sun image as used on the Japanese battle flags I'd be inclined to give this piece a second look.
... and I am NOT the seller looking to drum up interest.
