Official Japanese Language Pack for Windows — Simple, Reliable Locale Support
The Microsoft-created 日本語 ローカル エクスペリエンス パック provides native Japanese language and locale support for Windows installations, delivering accurate system translations and regional settings with minimal fuss.
Windows delivers ongoing language updates through the Microsoft Store via Local Experience Pack apps. These modules refine and refresh the operating system's interface text for supported locales and can be delivered automatically to devices.
Installation is handled through the Store and integrates with system updates. Text improvements can be reported using the built-in Feedback Hub—open it from the Cortana search box by typing “Feedback Hub” or by pressing Windows key + F.
- Purpose: keeps Windows UI text current and localized for specific languages.
- Features: modular language packs delivered through the Microsoft Store; updates can include corrections and wording improvements.
- Usability: simple Store-based installation and a direct feedback channel for suggesting text changes.
- Notes: additional language components (for example, spell-check dictionaries) may be installed; storage requirements vary depending on which features are selected.

FAQ
What is the "日本語 ローカル エクスペリエンス パック" (Japanese Local Experience Pack)?
It is a Microsoft Store package that provides localized Windows UI resources for Japanese. It supplies Japanese translations for system UI elements (Settings, notifications, built‑in apps and dialogs) so Windows can show its interface in Japanese.
Which Windows versions support Local Experience Packs (LXPs)?
LXPs are supported on Windows 10 (versions with Microsoft Store integration) and Windows 11. You must have a supported, up‑to‑date Windows release that can install packages from the Microsoft Store.
How is an LXP different from a full language pack?
An LXP is delivered through the Microsoft Store and typically contains the localized UI resources only (smaller, modular). A full language pack (installed through Settings or Windows Update) can include additional components and older deployment methods. For most users wanting the Windows UI in Japanese, the LXP provides the necessary translated resources.
How do I install the Japanese Local Experience Pack?
Open the Microsoft Store, visit the product page for the Japanese Local Experience Pack, and click Install (or Get). Alternatively, add Japanese under Settings > Time & Language > Language & region and follow prompts; Windows may install the LXP automatically from the Store when you add the language.
After installing the LXP, how do I switch my display language to Japanese?
Go to Settings > Time & Language > Language & region, add Japanese if it isn’t listed, then choose Japanese as the Windows display language. Sign out and back in (or restart) for the change to take effect.
Does the LXP change my keyboard/input method to Japanese?
No. The Local Experience Pack provides translated system UI. To type in Japanese you must add a Japanese input method (for example Microsoft IME) under Settings > Time & Language > Language & region > Options for the Japanese language.
Do I need internet access to install or update the LXP?
Yes — the LXP is distributed via the Microsoft Store, so an internet connection is required to download and receive updates. Windows Update/Store manages updates automatically when connectivity is available.
Can I remove or uninstall the LXP?
Yes. Remove Japanese from Settings > Time & Language > Language & region or uninstall the pack from the Microsoft Store or via Settings if presented. Removing it restores the previous display language if you had one configured.
Will installing the LXP change regional formats (date, time, number) or only the UI language?
Installing the LXP only provides the UI localization. Regional formats (date, time, currency, first day of week) are controlled separately in Settings > Time & Language > Language & region and Region — you can adjust those independently.
Where can I get more information or support if I have issues with the Japanese LXP?
Use the Microsoft Store product page for the pack, Microsoft support articles for language settings (Settings > Time & Language), or the official Microsoft support site. You can also check Windows Update and Store update history, and file feedback via Feedback Hub if installation problems occur.
