I'm not sure you'll run into many people who even have internet banking, and fees can get pretty heavy.
Why even state things you clearly have no understanding or experience of?
I live in Japan, numpty. Sending money back home can be a real pain in the arse, and everything costs here, even taking your own money out of the bank.
For what he's looking for, I doubt he'll find someone in Japan prepared to go through all the hassle unless it's serious cash, and then there's a huge amount of trust involved.
