I have inherited 2 flags from my father who was a US Marine serving during WWII on both Peleliu and Okinawa. He came across these flags while clearing caves. The Japanese soldiers had committed hari kari before the Marines entered the cave. I am curious to know if the flag owners can be identified. The first 2 pictures are front and back of one flag. The 3rd photo is front of the 2nd flag. Any assistance is appreciated.
