It actually cant be changed in game, it get detected by the System. So the only way would be to change the System Language for now, i guess :( sorry
The Font Details gets delivered with the game. However i saw your game is Mixed English/GermanWe gonna take a look on that asap.
So far we couldn't identify the Problem exactly, it looks like the Japanese Translation is missing (even its available). We will probably Update the Game with Language Selection.
