KeybladeLordSora, you just don't know how to do it. Go into the app store with no account logged in (on a computer or in browser on phone, NOT the app) and go to the region of Japan. You'll go to that store and try to download a free Japanese app and when it asks you to log in, click create new account and then create a new one and it'll be registered in Japan. it worked for me and I can download the app when it comes out.
