How to set system locale to Japanese

First, rest assured that installation of the Japanese language and changing your system locale settings to Japanese (Japan) does not change your PC's system language completely; it remains in your language. The installation simply adds an extra language to your computer so that the game plays without problem.

According to your OS, complete the change to Regional and Language Options (see the following).

Please note that if you encountered an error with a particular file, you need to do the following in addition to the language settings:

  • Delete the downloaded file from your PC before you configure the language settings.
  • Download the file once again with the new language / system locale settings.
