How to use Locale Emulator to run Japanese Games

Some games from Japan require the operating system to change location. In addition to changing the location directly in the windows system settings, I will show you a third software that has the same effect. Locale Emulator is a tool similar to MS AppLocale and NTLEA, providing a simulation function that can make an application recognize your OS as in a language other than the real one. It is quite useful when you are trying to play country-specific games.

Locale Emulator is a free open source program for Microsoft Windows devices to run programs in a locale other than the default locale of the operating system.
Designed specifically for playing computer games that require a specific locale, it can be used to run any program — be it game or application — as if the the underlying system would use that locale as the default.
Some programs may not run properly or at all if the system uses a locale that is not supported by it officially. If a game is released only in Japan for instance, it may require a Japanese system to run, and will refuse to do so if that is not the case.

The software works well on all versions of Windows from 7 to 10. However, I recommend using the Windows 10 version to play the most stable!

And now, let’s start the tutorial

Step 1: You can download Locale Emulator from Github or MEGA (both are sources of developer).



Step 2: Use WinRar or 7-zip to extract file “.zip”.

You should extract the files in a safe place, because after extract files will not be able to move.

Step 3: Run “LEInstaller.exe” and you can see the window.

*Install as current user: effect for current user only, does not require administrator privileges.

*Install for all users: the most reliable choice, require administrator privileges.

Or if you want use Locale Emulator without installation (portable), just close window now and don’t click any install button.

Step 4: Back your folder games and right-click to files “.exe” and you can see Locale Emulator tab in menu.

Unistall Locale Emulator

Run “LEInstaller.exe” in extract folder again and click unistall button.

Update new version

You can update new version in Github and MEGA (Link above). Just download, extract and overwrite all files of the old version. You need run ” LEInstaller.exe” and click install button again when update new version.


Locale Emulator supports 32-bit executables running on both 32-bit or 64-bit systems. For example, if you are using 64-bit WinRAR, you will not see the context menu on a RAR file unless you swapped 64-bit WinRAR with the 32-bit version.
