japanese flag

What a wonderful thing y'all are doing here!! I hope to take what clues I can gather here i.e. names, dates, places and make a more complete picture of what these flags saw. I'm horribly curious about the temple stamps as well. Without the story its just a piece of cloth. Thank you so...

Hello, My family has had this flag for a while. I was hoping someone could help me with translating it and maybe even authenticating it. It supposedly has Hideki Tojo's signature on it, or at least that's what the paper on the back seems to imply. Sorry the pictures aren't great. If it helps...
