Sorry but I highly do not recommend doing anything to bypass and getting into jTO. Why? It's region locked for a reason, you could get in serious trouble. Some people would even go out of their way to report you.
Even if you did managed to find a way, this could put you guys on high alert. I'm pretty sure a few people are gonna blurt out "I'm playing jTO in the US(or somewhere besides Japan)" or something around those lines and cause a whole road of chao.
Just my warning, I am not your hands or brain so it's up to you to decide what to do.
