How can I set my system locale to Japanese?

  • Updated

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; the display language of your operating system will remain the current language you have.
The installation simply adds the language capability to your computer, and the system local setting allows for non-Unicode compatible games in that language to run without problem.

According to your OS, complete the change to Regional and Language Options (further details for each OS provided below.)

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.

After you have changed the system locale settings to "Japanese (Japan)", make sure that you delete any previously downloaded product data from your PC. DELETING such files is an IMPORTANT step because changing your settings alone will not fix 'mojibake' (garbled text).
Once you have made the changes below and deleted the old files, please download and extract the product once more.

[Note: We recommend the use of 7zip for extracting files on DLsite.]

  • We also strongly recommend that you download the files to a folder in your local disk and extract them there. Specifically: C:\DLsite\ (* please create this folder for troubleshooting)
  • Placing files in a location with a long file-path, in system protected areas of the operating system, and in the 'user' specific file-paths such as "Downloads" and the "Desktop" will often cause problems and prevent some products on DLsite from starting and functioning normally.
  • This is especially the case for all customers who have their OS Display Language set to anything other than English / Japanese.
