上

A young men's association (青年団) of the place (上間垂川; Uematarekawa?), I don't know where is 上間垂川.

Do you think it could be a flag from Okinawa? There is indeed an address called 上間 in the current Naha city.

The Chinese characters (kanji) on the flag are old forms, so it's probably several decades old unless it was intentionally designed this way.

the man who obtained the flag did fight during world war 2 on Okinawa and presumably obtained it at that time. Are the two large characters in the center of the flag the name of the young men's organization? Does anyone know the purpose of that organization?

Are the two large characters in the center of the flag the name of the young men's organization?

It's one character, not two. It's a current version of the third character from the bottom of the vertical writing.

Does anyone know the purpose of that organization?

Like the other poster said, it's a youth association just like YMCA or Boy Scouts, so what do you do there?

So it's kind of like a YMCA flag might have "Young Men's Christian Association" written at the edge and then there is the letter Y or something in the middle.

Thank you very much. All mysteries are now solved!
