Or have they block everything, because you can receive bitcoin it must be a way to pay the seller, just try to think outside the box.
Also if you want to buy with sending from a Japanese account everyone in the world can accept it with t.e.x create a Payoneer account.

Thanks for your message.
Due to security and privacy concerns I only want to deal in cash. I can't just send some 4 digit $ amounts to strangers for obvious reasons. These transfers are no reversible and especially paypal, which I stopped using years ago, is a pure scam trap in my eyes.
Also, I can't open a Japanese bank account yet for stated reasons. If I had one I could also just use a Japanese exchange.
