When will the ufc go back to japan.?

I have seen some interviews with dana white saying that he is going to bring ufc events to japan.but when will that be.and white also said that japan has a bigger market for mma than the states.he also so said that doing business in japan is hard because some people in japan are out to get him and what not but i can rant about all that right now.so what do you think.ps and i think the people he said who were out to get him were yakuza LOL.
