While there are some English words in the menus, mainly the main topics like "play," "mobile suit," "settings," etc, all the rest of the menus are in Japanese. Information like how to unlock emblems and titles are completely in Japanese. I think quickly there will be menu translations for those that need it. It won't be hard to get around the game for those that don't know Japanese once they get the game. Other than that of course the voices are in Japanese. It's not a very intensive Japanese title, except for the unlock information but those arent so bad to be honest as you can actually see that info in very basic one word English on the mobile suit selection screen as well as the longer i go in Japanese.
