You can pay for games on the Japanese eShop with a Japanese PayPal account, which you can set up with any credit card that hasn't been used on PayPal before and can pay in JPY! Alternately, use a Japanese credit card or eShop credit.
That is just confusing lol.
To set up a japanese paypal wouldn't you need a japanese address?
