You can buy BitCash gift cards on a few online shops, like Play-Asia. That works with some sites that accept BitCash (example: Lovepop/Digi-Gra).
I saw someone post here in the forums that they are based in Japan and can help with bank transfers and such if you opt for that, perhaps they might take a small cut of the funds for the trouble. Can't remember which thread it was, but they are a new member anyway, so of course it's harder to trust.
