If you are running Windows 2000 or Windows XP, it is assumed you have already set your locale to Japan by setting the Language for non-unicode programs to Japan. If not, you will need to set it. The step may require you to have your Windows 2000 or Windows XP installation media at hand.

If you are running Windows Vista or Windows 7, once language packs are installed, it has a built-in localization system, and no further steps can be taken.

If you are running Ubuntu see the guide here.


  1. Install support for asian languages in your OS. You do not need to set Japanese locale.
  2. On Windows: download and install Microsoft AppLocale (free).
  3. Download and install jZip (free).
  4. Launch AppLocale, select "launch an application" and browse to jZip.exe or its desktop link, and finally - select 日本語 language (last in dropdown list). AppLocale will open jZip in Japanese environment, and you can simply open Japanese zip archives and extract files with UTF names.
  5. On Linux: use "unzip" with specifying zip encoding in launch command.
