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.
