Dialogue language

[RLofOBFL]

You can change the text to Japanese, I do it sometimes to practice. When you boot up the game, there is an option on the log on screen in the bottom left corner(PS4) that has English selected, you can click this & change text to Japanese. You can only change it when booting up the game, exiting from being logged in back to the log in screen will lock it. Settings in game on System has voice change to Japanese.
