Is it too late for me to create a JP account?

I've been playing bandori for almost 8 months but only EN server because well I don't understand japanese ( I'm working on that tho). So these past few months I've been going back and forth about whether I should create a JP acc, but that would mean I have to invest time to level up the area items, get all the cover songs, etc.....So I'm not sure if I want to start all over again? I need other opinions on the matter. What do you guys think? Should I create the JP account or not?
