Cursor IDE

Describe the Bug

Summary

The Japanese locale is active, but the main application menu is only partially localized.

Actual behavior

Only “Run” is translated as “実行(R)”. The following standard menus remain in English:

  • File
  • Edit
  • Selection
  • View
  • Go
  • Terminal
  • Help

The Japanese Language Pack is installed, and the locale is set to Japanese. The problem occurs consistently after restarting Cursor.

Environment

  • Cursor version: 3.11.13
  • Embedded VS Code version: 1.125.0
  • Operating system: Windows 11, build 10.0.26200
  • Japanese Language Pack version: 1.125.0
  • Extension ID: ms-ceintl.vscode-language-pack-ja

Steps to Reproduce

  1. Open Cursor IDE on Windows 11.
  2. Install “Japanese Language Pack for Visual Studio Code”.
  3. Set the locale to Japanese with the following configuration in argv.json:
    {“locale”: “ja”}
  4. Fully quit Cursor.
  5. Restart Cursor.
  6. Open the editor window and check the application menu.
  7. Observe that only “Run” is displayed as “実行(R)”, while File, Edit, Selection, View, Go, Terminal, and Help remain in English.

Expected Behavior

When the Japanese locale and the official Japanese Language Pack are enabled, the standard application menus should be displayed in Japanese, including File, Edit, Selection, View, Go, Terminal, and Help.

At minimum, Cursor should clearly document which parts of the application menu are not localized.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the detailed report. Important note: this isn’t a bug, it’s an expected limitation.

Cursor is a VS Code fork, and third-party language packs work on a best-effort basis. Most of the UI gets translated, but some menu chrome stays in English, including the top-level menu bar labels File, Edit, Selection, View, Go, Terminal, Help. Cursor’s own pages Settings/account and the Agent/Chat window also stay in English.

Why only Run is translated right now: on July 7 both Cursor and the language pack updated. When a pack is rebuilt against a new VS Code baseline, its NLS bundle can get out of sync with the fork, and strings that used to be translated can revert to English. Reinstalling the pack or switching the display language won’t fix this.

What you can try right now is rolling back the language pack to a version from before July 7:

  • Open Extensions, find Japanese Language Pack
  • Click the arrow next to Uninstall or the gear icon, then pick Install Another Version
  • Pick a version from before July 7
  • Restart Cursor

If the menu bar gets translated again on the older version, it points to the extension update, and it’s worth reporting to the pack maintainer.

Full UI localization including the menu bar is a separate open feature request, there’s no ETA yet: Add support for Chinese

The same issue was discussed here in Chinese but the situation is identical: The title bar area of cursor IDE cannot display Chinese Let me know if the rollback helped.
