This article introduces how to change the system language/display language on Windows 11 to Japanese, English or other languages. Especially in programming, changing the language to English makes error messages appear in English, so you can get more information from internet searches and problem solving becomes more efficient.
Open Windows 11 Settings and go to Time & Language > Language & Region. Settings can be opened using the “win-I” keyboard shortcut.
If you search for “language” in the settings screen, it should be a shortcut. Click “Add a language” to add a new language (such as Japanese or English).
Search for, select and add the language you want to set, such as Japanese or English.
On the next screen, make sure “Set as my Windows display language” is checked. Also make sure that language pack checkboxes are not unchecked.
Download and installation will take a few minutes, so wait during that time.
Sign out or restart is required to enable the new language. If there are no problems, click “Sign out” and log back in. (Sign out is different from restart.)
At this point, software and interfaces on Windows 11 will be displayed in the configured language.
With these steps, you can change the system language/display language on Windows 11 to Japanese, English or other languages.
