Three settings that are easy to confuse
Changing a Switch game from Japanese to English can involve three separate controls. Treating them as one setting is the cause of most failed attempts.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minute| Control | What it changes | What it does not change |
|---|---|---|
| System language | The Switch menus and, when supported, a game’s default language. | It cannot add an English translation that is absent from a game release. |
| System region | The console’s selected region and the regional terms it uses. | It does not switch a Nintendo Account to a different eShop country. |
| Nintendo Account country/region | Which account storefront and regional download or prepaid codes the account can use. | It does not automatically change the language or System > Region setting on the console. |
For a Japanese cartridge, start with the system language. For a Japanese digital purchase or code, verify the account country/region separately. For downloadable content or online features, check the relationship between the game’s release, the storefront, and the account before buying.

Before changing a setting
Identify what you actually bought. A Japanese game card, a Japan-specific eShop download, and a Japanese prepaid or download code have different regional requirements. Also identify the exact release, because a game’s North American, European, and Japanese editions may not contain the same language data.
Save your progress and close running software before changing the system language or region. Nintendo requires a restart for both changes, and changing the language closes suspended software. A restart is normal; it is not evidence that the imported game is incompatible.
Change the Switch system language
Nintendo’s official instructions use this path: HOME Menu > System Settings > System > Language. The console must restart after you select a new language, and any suspended software is closed.
- From the HOME Menu, open System Settings.
- Scroll down the left-hand column and select System.
- In the right-hand column, select Language.
- Choose the language you want the console to use, such as English or Japanese.
- Confirm the restart when prompted. Save progress and close any game first, because changing the language ends suspended software.
After the restart, launch the Japanese game. If the release supports the newly selected language, it normally adopts that language automatically. If the game remains Japanese, continue with the title-specific checks below rather than repeatedly changing the console setting.
Japanese is one of the supported system-language choices. The setting changes the console interface immediately after the restart, but it does not alter the text, voices, or menus that the publisher included in a particular game build.
Change the Switch system region
Region is changed independently from language. Nintendo’s procedure is documented at Nintendo Support’s region instructions.
- Open System Settings from the HOME Menu.
- Select System in the left column.
- Select Region in the right column.
- Choose one of Nintendo’s listed choices: Japan, The Americas, Europe, Australia/New Zealand, or Hong Kong/Taiwan/South Korea.
- Select the option to continue.
- Read the end-user license agreement for the selected region and accept it if you agree.
- Restart the console when prompted.
A region change is usually unnecessary merely to boot an imported physical game. Change it when a particular service or software instruction specifically requires a different console region, and remember that this action does not change the Nintendo Account country/region used by the eShop.
The end-user license agreement is part of the procedure, not an optional notice. If you decline it, the region change does not complete. The region menu also does not provide a hidden language pack or convert a Japanese-only release into an English release.
Why setting the console to English may not translate a Japanese game
Nintendo’s rule is: “The language for a game or software application will default to the language setting that has been selected on the console, so long as the intended language is supported by the game or software application.” In practice, the game contains its own language data. The Switch can select English from that data, but it cannot download or generate a translation that the publisher left out.
- Set the console to the desired language.
- Start the game and allow it to read the console setting.
- If English is included in that Japanese release, the game normally starts in English or offers it as an available option.
- If English is not included, the menus and text stay Japanese unless the publisher provides an in-game language selector with another supported choice.
Do not assume that a Japanese edition has the same languages as a North American, European, or other regional edition. Language support is release-specific, even when the title and cartridge shape appear identical. Changing the system region cannot supply missing language files, and changing the account country cannot supply them either.

If a title has an in-game language menu, follow the publisher’s instructions for that menu. Nintendo’s automatic-language rule describes the default behavior; it does not promise that every title exposes the same options or uses the same menu design.
How to verify language support before you buy
Check the exact Japanese release, not just the game’s international marketing page. Use the official Nintendo eShop product description for that edition, the publisher’s product page, or the game’s manual. Look for an explicit supported-language list rather than relying on a retailer’s shorthand such as “import” or “Japanese version.”
Use this pre-purchase checklist
- Edition: Confirm that the listing is the Japanese release, including the correct physical or digital edition.
- Supported languages: Verify that English, Japanese, or your preferred language is expressly listed.
- Format: Note whether you are buying a game card or a digital copy; their storefront and code requirements differ.
- DLC: Check whether add-on content is sold for the same regional release.
- Online services: Look for any account, server, or storefront restriction stated by the publisher.
- Updates: Confirm how the release receives patches and whether the update is available from your normal account.
Save a copy of the product information or note the edition identifier before ordering. Retail listings can use broad phrases such as “language: Japanese” or “import” without explaining whether English is included. The official listing for the specific release is the safer reference.
Nintendo does not publish an aggregate percentage of Japanese Switch games that include English. There is no reliable single number to apply to every import; the individual product listing is the authoritative check.
Can an imported Japanese physical game work on another-region Switch?
Nintendo’s Japanese support guidance says overseas-released physical Nintendo Switch software works on a console sold in Japan, while also warning that Nintendo has not tested every software title and cannot guarantee operation or after-sales service. This supports cross-region cartridge use in many cases, but it is not a promise that every game, accessory, online feature, or add-on combination will function identically.
Before ordering a cartridge, separate these questions:
- Will the cartridge boot? This is the hardware and basic software-compatibility question.
- Does this release contain English? A cartridge can run perfectly while offering Japanese only.
- Will DLC and online features work? Add-on content and services may expect a matching storefront or account region.
A successful first launch answers only the first question. Test or verify the other two before buying expensive downloadable content or committing to online play. Nintendo’s limited testing statement also means that a retailer’s claim that “Switch games are region free” should not be read as a universal support guarantee.
Compatibility can therefore be good enough for a physical purchase while still leaving a support risk. Keep the receipt and check the seller’s return policy when the exact title has not been documented by Nintendo or the publisher.
Japanese eShop purchases and download codes
Japanese digital purchases are controlled by the Nintendo Account country/region, not simply by the language selected under System Settings. Nintendo’s Japan eShop guidance requires the Nintendo Account country/region to be Japan for Japan-specific eShop purchases. Japan-issued download cards and Nintendo prepaid cards likewise require that Japan setting before redemption.

- A Switch set to English can still use a Japan-set Nintendo Account; language and storefront are separate choices.
- A Switch set to Japan does not, by itself, make a non-Japan account eligible for Japanese eShop purchases.
- A Japanese prepaid or download code can fail on a US, European, or other-country account even when the console region says Japan.
Changing an account’s country/region can have consequences for the account’s balance, subscriptions, payment methods, and Nintendo’s account rules. Review Nintendo’s current account requirements before making that change, and resolve any balance or subscription issue that could prevent the switch.

Do not treat the console’s Region menu as a workaround for a code restriction. The account country/region is the value Nintendo checks for Japan-specific purchases and Japan-issued codes. Keep those two settings in your troubleshooting notes so you can tell whether a failure is a console-setting issue or an account-storefront issue.
Account-change checklist
- Confirm that the desired game or code is Japan-specific.
- Check the Nintendo Account country/region, rather than only the console region.
- Review current Nintendo rules concerning account balance, subscriptions, and payment methods.
- Only then change the account country/region if it is appropriate for your situation.
- After the change, verify the storefront and code eligibility before purchasing additional content.
Physical cartridge versus digital purchase
| Buying method | Primary check | Common regional dependency | Language outcome |
|---|---|---|---|
| Japanese game card | Whether the card boots on your console. | DLC, updates, and online services may depend on the release or storefront region. | Only the languages included on that cartridge’s release are available. |
| Japanese eShop download | Nintendo Account country/region must be Japan for Japan-specific purchases. | Payment method, storefront access, downloadable content, and account rules can be regional. | Uses the console language only when that digital release supports it. |
| Japanese download or prepaid code | The redeeming Nintendo Account must be set to Japan. | Code redemption is tied to the issuing region. | The code does not change the software’s included languages. |
Choose the format after checking language support. A cartridge can avoid a Japan eShop purchase requirement, but it does not guarantee English text or unrestricted DLC. A digital copy can be convenient, but the account-country requirement and regional code rules must be satisfied first.
For a physical purchase, separate the one-time ability to start the game from continuing access to patches, add-ons, and online services. For a digital purchase, confirm the account storefront before paying. In both cases, the language list remains a title-specific question.

“My Japanese cartridge is still in Japanese after I selected English.”
Confirm that the console actually restarted in English, then check the exact release’s official language list. If English is not listed, no System Settings change can add it. An in-game language menu helps only when the publisher built English or another language into that release.
“The cartridge launches, but its DLC is missing or unavailable.”
Verify that the DLC belongs to the same regional release as the cartridge and that the account using the eShop can access that storefront. A cross-region cartridge and a different-region add-on are not automatically a compatible pair.
“A Japanese download code will not redeem.”
Check the Nintendo Account country/region, not only the console’s System > Region value. Japan-issued codes require the account country/region to be Japan. If changing the account is appropriate, review balance, subscription, payment, and account-rule implications first.
“The system asks me to accept terms when I change region.”
That is expected. Nintendo requires you to review and accept the selected region’s end-user license agreement before the restart can complete. If you do not accept it, the region change will not finish.

“Changing language closed my game.”
This is also expected. Nintendo warns that changing the system language closes suspended software. Save your progress and exit the game before changing the setting, then relaunch it after the restart.
“I changed the console to Japan, but the eShop is still not Japanese.”
System Region and Nintendo Account country/region are separate. The console setting does not automatically move an account to the Japan storefront. Check the account country/region requirement for the purchase you are attempting.
“The game boots, so can I assume every feature works?”
No. Booting confirms only basic cartridge recognition. Language availability, DLC entitlement, updates, and online-service compatibility require their own checks.

Practical setup examples
English-speaking player with a Japanese physical game
- Check the Japanese product listing for English support.
- Leave the console region unchanged unless the game or service specifically requires another region.
- Set System > Language to English and restart.
- Insert the cartridge and launch it.
- If the game remains Japanese, treat that as a language-content limitation, not a region-setting failure.
Player who wants the Japanese interface
- Choose Japanese under System > Language.
- Accept the restart.
- Launch the game; supported Japanese releases should follow the console setting.
- Keep the account country/region unchanged unless you also need access to Japan-specific digital purchases.
Player buying a Japan-only digital release
- Confirm the release’s languages and DLC requirements.
- Use a Nintendo Account with country/region set to Japan for the Japan-specific eShop purchase.
- Check that your intended payment method and any future DLC purchase will work with that storefront.
- Set the console language to English or Japanese according to the language list, then restart before launching.
Player redeeming a Japanese prepaid card
- Confirm that the card is issued for Japan.
- Verify that the Nintendo Account country/region is Japan.
- Review account balance, subscription, payment, and country-change implications before modifying the account.
- Redeem the code only after the account meets the regional requirement.
Decision guide before importing
| If your priority is… | Verify first | Do not assume |
|---|---|---|
| English menus and text | English listed for the exact Japanese release. | The console’s English setting can translate Japanese-only software. |
| Lowest storefront friction | Whether a physical card meets your language and DLC needs. | A cartridge eliminates every regional online or add-on issue. |
| Japan-only digital access | Japan-set Nintendo Account and compatible payment or code method. | Setting System > Region to Japan changes the account storefront. |
| Long-term DLC and online play | Regional relationship among the game, account, DLC, and service. | Cross-region components will always share entitlement or servers. |
| Official support | Nintendo’s title-specific information and stated compatibility limits. | Every imported title has been tested or receives domestic after-sales support. |
Use this order when comparing listings: language support first, format second, DLC and online requirements third, and account or storefront rules fourth. That order prevents a cheap cartridge or attractive digital listing from becoming unusable for the way you intend to play.

Frequently asked questions
How do I change a Japanese Switch game to English?
Set the console to English at HOME Menu > System Settings > System > Language, accept the restart, and launch the game. This works only if the specific Japanese release includes English.
Do I need to change my Switch region to play a Japanese cartridge?
Usually not. Nintendo says overseas physical Switch software works on consoles sold in Japan, while warning that it has not tested every title. Check the game’s language, DLC, and online requirements separately.
Can I play Japanese Switch games in English?
Yes, when English is included in that release. Verify the official product description, publisher page, or manual for the exact edition; the console language cannot add absent translation data.
Are Japanese Nintendo Switch games region locked?
Imported physical software generally runs across console regions, but Nintendo does not guarantee every title, accessory, online feature, or after-sales service. Digital storefront and code rules are separate and depend on the Nintendo Account country/region.
Can I use a Japanese eShop code on my US account?
Japan-issued download and prepaid codes require the Nintendo Account country/region to be Japan. Setting the console’s System > Region to Japan is not the same account change.
Will changing the system language delete my save?
The documented effect is that suspended software is closed and the console restarts. Save and exit the game before changing the setting so you do not leave unsaved progress suspended.
Why does my game remain Japanese after I changed both language and region?
The release may not contain English. Region and language settings cannot install a translation. Confirm the exact release’s supported-language list and look for a publisher-documented in-game selector.
Can Japanese DLC be added to a cartridge from another region?
Do not assume so. Check that the DLC belongs to the same regional release and that the account can access the required storefront. Cartridge compatibility alone does not establish DLC compatibility.
Recommended Free Tools

Frequently Asked Questions
How do I change a Japanese Switch game to English?
Set HOME Menu > System Settings > System > Language to English and restart. The game changes only if that specific Japanese release includes English.
Do I need to change my Switch region to play a Japanese cartridge?
Usually no. Imported physical software generally works across regions, but Nintendo has not tested every title and does not guarantee every feature or after-sales support.
Can I use a Japanese eShop code on a US account?
No. Japan-issued download and prepaid codes require the Nintendo Account country/region to be set to Japan. The console’s Region setting alone is not enough.
Why is my game still Japanese after I selected English?
Check the exact release’s official language list. If English is absent, changing system language or region cannot add it.
Will Japanese DLC work with an imported cartridge?
Verify that the DLC matches the cartridge’s regional release and that your account can access the required storefront. Do not assume cross-region DLC is compatible.
Does changing language erase my save?
Nintendo documents that suspended software is closed and the console restarts. Save and exit your game before changing the language.
Are Japanese Switch games region locked?
Physical imports generally run on consoles from other regions, but Nintendo does not guarantee every title, accessory, online feature, or support outcome.

The Bottom Line
Set System > Language to English or Japanese and restart; change System > Region only when a service requires it, accepting the regional EULA. Neither setting can add language data that the game does not contain. Confirm the exact release’s languages, DLC, and online requirements before importing. For Japan-specific eShop purchases and Japanese codes, use a Nintendo Account whose country/region is Japan, remembering that this account setting is separate from the console’s region.
