Anyone back home have the ability to cash it for you and convert it to Japanese Yen and send it back to you? If they had the same last name as you , the back would probably be OK with cashing it as long as you signed the back. I'd offer to help , but my bank would probably question it unless I got it OKed ahead of time. I think the Bank of America sells Yen to convert it. If you can't figure anything out , let me know and I will see if my bank here in Maine will help. I'd offer to send/mail you $600 cash American , but I don't trust the mail , LOL. Anyway if you get desperate , private message me and I'll try to help.
