Hello, this forum has helped me a lot with memorabilia. I purchased this flag along with another that were brought back from a Marine who saw combat in Guadalcanal and Tarawa. I’ve been told the owner of this flag was “Sadao Yatani” I’m hoping if anyone can translate a unit or address on this flag so I can gather more history on it. Also I found two stamps on the top of the flag. Not sure what they mean either. Thank you!
