My husband passed away and I found an 8"x10" piece of paper that is all in I assume Japanese script and he had written "Jap Bond" on the side. He was on Okinawa during WW2. The back has columns with script and some are stamped in red. There are no pictures and no English. I would like to pass it to nephew and would like to give him a history. Any help I would appreciate and thank you in advance for your time.

Since we cant see it then you may need to take it to a japanese person and have it translated for you. If you live near a major metro area there is a good chance that there are japanese students there that could tell you what you have. Most of the sources I have found are smaller in size.

War Bonds and Other (http://scripophily.net/military-collectibles.html)

Does it appear to look like any of the examples I have given ?

Also if you can or wish to post a photo of it here, someone may be able to translate it. If it is not too much writing.
