7 君乃ためなに可おしまん若桜 Why should I miss my life for Emperor?
In my impression, seeing the writing style, one person wrote all these letters.
The last phrase "Why should I miss my life for Emperor?" is coming from a famous farewell poem left by Maj. Shigemi Furuno who rushed into the Pearl Harbor with his mini-sub.
As I can find no soldier's name to be given this flag, I think this is a souvenir one produced in the post war.
