Actually you can, you just need to set it as a primary account.God I'm so close to caving and just buying a Japanese game digitally, the closest I got to this was as simple as buying The Walking Dead season 1 off the US store before it was classified in Aus, although this has a little more of a language barrier, and I can't remember, you have to make Japanese psn, yeah? and there's no way to tie the game back to your original account for trophies, etc?
