If you mean puyo puyo Tetris, it doesn't have English in the Japan version afaik. You'll have to find your way through the menu until the English version is released. The first two options on the main menu are 1 and 2 player respectively. The rest is fairly easy to figure out. It's what I've been doing
Get and android phone and google translate. It will use the camera to do live translation.
I had to do this before on a lot of stuff to find out how to change it to english.
