To change the Switch interface language, open HOME Menu > System Settings > System > Language, choose English, Japanese, or another available language, and let the console restart. To change the console region, open HOME Menu > System Settings > System > Region, select a region, accept its end-user license agreement (EULA), and restart.
Those settings do not translate a Japanese game automatically. A game follows the console language only when that specific release includes the selected language. Check the Japanese edition’s official product description before buying. Physical Japanese game cards generally run on consoles sold in other regions, but Nintendo says it has not tested every title and does not guarantee operation or after-sales support.

What the Switch language and region settings actually control
Three different settings are often confused when importing Japanese software:

For a Japanese cartridge, the first setting to try is normally System > Language. Changing the console region is a separate decision and is not required simply because the cartridge was sold in Japan.

Change the Switch system language
Nintendo documents the following path in its official system-language instructions.
- From the HOME Menu, select System Settings.
- Scroll down the left column and select System.
- In the right column, select Language.
- Choose the language you want, such as English or Japanese.
- Allow the console to restart when prompted.
The restart is part of the change, not an optional confirmation. Nintendo warns that changing the system language closes suspended software, so save any work and close an application before changing the setting. After the reboot, launch the game again rather than relying on a previously suspended session.
This procedure changes the Switch menus as well as the language preference supplied to compatible software. It does not download language packs, alter the game card, or change the region of a digital storefront. You can repeat the same steps later to return to your original language.
Change the Switch system region
Use the region setting only when you have a reason to change the console’s geographic configuration. Nintendo’s region instructions list five choices: Japan, The Americas, Europe, Australia/New Zealand, and Hong Kong/Taiwan/South Korea.
- Open HOME Menu > System Settings.
- Scroll down the left column and select System.
- Select Region in the right column.
- Choose Japan, The Americas, Europe, Australia/New Zealand, or Hong Kong/Taiwan/South Korea.
- Select the option to continue.
- Read the EULA for the selected region and accept it if you agree.
- Let the Switch restart.
Accepting the EULA and restarting are required. This setting is independent of your Nintendo Account country/region; changing one does not automatically change the other. A region change also does not create an English script for a Japanese-only release.
How a Japanese game decides whether to show English
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 practical terms, the Switch supplies the preferred language, but the game release supplies the available translations.
- Set the console to the language you want.
- Restart if the Switch requests it, then launch the game.
- If that Japanese release contains the selected language, it will normally use it automatically.
- If the release does not contain that language, the console setting cannot create a translation. Look for an in-game language menu only when the publisher’s documentation says one exists.
A Japanese game therefore can fall into several different cases:
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →- Japanese and English included: setting the console to English normally starts the game in English.
- Japanese only: changing the Switch language to English leaves the game in Japanese.
- Several languages with a game menu: the console language may establish the default, while the game’s own options menu can provide a manual choice.
- Language support documented unclearly: treat the release as unconfirmed until you check the official product description, publisher page, or manual.
Do not infer language support from the game’s title, cover art, a different regional release, or a video showing another edition. Language data can differ between Japanese, North American, European, and other releases. Nintendo does not publish an aggregate percentage of Japanese Switch games that include English, so there is no reliable platform-wide statistic to use in place of a title-by-title check.

Text and voice support should be considered separately when a listing distinguishes them. A release might include English menus or subtitles without English voice audio, or list several text languages while retaining Japanese voices. Only the exact listing or publisher documentation can establish what is included.
Where to verify language support before buying
Check the exact Japanese edition you intend to purchase, not merely the franchise or an international listing. Use the official Nintendo eShop product description for that edition when available, then compare it with the publisher’s product page or the game manual. Look for an explicit list of supported text and voice languages; “Japanese version” alone does not establish whether English is included.
Record the answer for the exact format as well. A physical Japanese cartridge and a digital release can have different listings, update requirements, or downloadable-content arrangements. If the listing does not state English support, regard English as not stated rather than assuming it is present.
When buying from a marketplace, ask the seller for the region and product code of the actual cartridge or download listing. Do not rely on a photograph of a multilingual box if the seller may be shipping a different revision. Keep the listing and return terms until you have confirmed the game’s language on your console.
Can an imported Japanese physical game work on another region’s 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. That supports cross-region use for many imported cartridges, but it is not a promise that every game, accessory, online feature, or add-on will work identically.
When evaluating an imported cartridge, separate these questions:
1. Will the game card boot?
Many physical Switch imports run on hardware sold in another region. Nintendo’s limited testing means you should retain the seller’s return options and avoid treating compatibility as guaranteed for every title.

2. Does this edition contain English?
Hardware compatibility says nothing about translation. Confirm the language list for the Japanese release itself. Setting the console to English helps only when English data is included in that release.

3. Will DLC and online services match?
Check whether downloadable content, updates, redemption codes, and online services require a matching storefront or account region. A cartridge may start while a regional add-on or code remains unavailable to your usual account.
| Import question | What to verify | Why it matters |
|---|---|---|
| Console compatibility | Whether the game card boots on your Switch model | Nintendo has not tested every title and gives no universal guarantee |
| Language | Supported languages for the specific Japanese release | The console cannot add a missing translation |
| DLC and updates | Whether add-ons or updates require a particular storefront or account | The base cartridge and its downloadable content can follow different regional rules |
| Online services | Any publisher or service-region requirement | Starting the game does not prove every online function is available |
“Region free” should therefore be read narrowly. It describes the ability of many game cards to run across console regions, not a guarantee of matching DLC, every online service, customer support, or language availability.
Do you need to change the console region to play a Japanese game?
Usually, no. Start by leaving System > Region unchanged and changing only System > Language if you want the interface or a supported game language to change. The physical-import guidance does not require you to set the console region to Japan before inserting a Japanese game card.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Change the console region only when you specifically need that system-level region choice and understand the EULA and restart it entails. It will not force a Japanese-only game to display English, and it will not turn a non-Japan Nintendo Account into a Japanese account. If your only goal is to read an English-supported game, changing the language alone is the less disruptive test.
Japanese eShop purchases and prepaid codes
Digital purchases follow Nintendo Account country/region rules rather than the console’s Language setting. Nintendo’s Japan eShop guidance requires the Nintendo Account country/region to be set to Japan for Japan-specific eShop purchases. Japan-issued download cards and Nintendo prepaid cards likewise require a Nintendo Account with Japan selected as its country/region.
Changing System Settings > System > Region is therefore not a substitute for changing the account country/region. Before changing an account country/region, review Nintendo’s current rules for account balance, subscriptions, payment methods, and other account implications. Make the account decision before buying a regional code; a code issued for Japan cannot be assumed to redeem on an account set to another country.
The account setting and the console setting solve different problems. The console language tells compatible software which language to request. The account country/region determines the storefront context and whether Nintendo’s Japan-specific purchases or codes are eligible. Neither setting can add a translation that the game release does not contain.

| Japanese digital purchase | Access is tied to the Japan-specific storefront | Check the listing for that digital release | Nintendo Account country/region must be Japan for Japan eShop purchases |
| Japanese download or prepaid code | The code is issued for Japan | The code does not change game language | Nintendo says the account country/region must be Japan to redeem it |
Common pitfalls when importing
- Assuming the console setting is a translator: Language selection only chooses among languages shipped with the software.
- Checking the wrong edition: A North American or European listing may document languages that are absent from the Japanese release.
- Confusing region with account country: The System > Region menu does not switch the Nintendo Account storefront.
- Buying a code before checking the account: Japan-issued download and prepaid cards require Japan as the account country/region.
- Assuming a working cartridge proves DLC compatibility: Add-ons, updates, and online services can have their own storefront or account requirements.
- Ignoring the restart: Both language and region changes require a restart, and a language change closes suspended software.
- Expecting universal Nintendo support: Nintendo has not tested every imported title and does not guarantee after-sales service for all of them.
Troubleshooting: what to do when English does not appear
The console is in English, but the game remains Japanese
That behavior usually means English is not included in that Japanese release, or the game requires a separate in-game language choice. Recheck the official listing for the exact edition. If English is not listed, no system setting can add it.

The game changed language unexpectedly
Verify the Switch’s current setting under System Settings > System > Language. A supported game normally follows the console language, so changing the system language can change the game’s default the next time it launches. Remember that the change closes suspended software.
The cartridge starts, but DLC or a code does not work
Treat this as a storefront or account-region issue, not a language issue. Confirm whether the add-on or code requires Japan, whether your Nintendo Account country/region is Japan, and whether the publisher documents a matching-region requirement. Do not assume that a working base cartridge proves the DLC will work.
The Switch asks for a region EULA
That prompt is part of the console-region procedure. Read the selected region’s EULA and accept it only if you agree, then allow the required restart. This prompt does not indicate that the game itself has been translated.
An imported title will not run or lacks support
Nintendo explicitly limits its assurance because it has not tested every overseas title and does not guarantee after-sales service for all imported software. Check the cartridge, console model, required updates, and seller return policy. If the problem concerns an online service or add-on, check its regional requirements independently.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A pre-purchase checklist for Japanese Switch games
- Language: Is English or your preferred language explicitly listed for the Japanese release?
- Format: Are you buying a physical card, a Japanese eShop download, or a Japan-issued code?
- Console: If physical, has compatibility for your hardware been confirmed, while recognizing Nintendo’s limited testing?
- DLC: Do the planned add-ons require a matching storefront or account country?
- Online play: Does the publisher specify a region requirement for servers or services?
- Account: If digital, is your Nintendo Account country/region set to Japan where Nintendo requires it?
- Support: Are you prepared for limited Nintendo after-sales support on an imported title?
The safest sequence is to verify the exact release’s language list first, decide between physical and digital formats second, and then check DLC, online, and account requirements. Change the console language only after purchase if needed; change the console region or Nintendo Account country/region only for a specific regional requirement you have confirmed.
Quick reference
| Goal | Action | Restart or agreement |
|---|---|---|
| Use English or Japanese on the Switch | HOME Menu > System Settings > System > Language | Restart; suspended software closes |
| Change the console region | HOME Menu > System Settings > System > Region | Accept the selected region’s EULA, then restart |
| Buy from the Japan eShop | Set Nintendo Account country/region to Japan | Review current account balance, subscription, and payment implications first |
| Redeem a Japan-issued code | Use a Nintendo Account with country/region set to Japan | Console language and console region alone are insufficient |
A Japanese Switch game uses English only when that particular release contains English. The console language path controls the default, physical imports often operate across console regions with Nintendo’s stated limitations, and Japanese digital purchases or codes require the appropriate Nintendo Account country/region.
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 again. This works only if the Japanese release includes English. If English is absent from that edition, the console cannot add it.

Are Japanese Nintendo Switch games region locked?
Many imported physical game cards run on consoles sold in other regions. Nintendo says overseas physical software works on domestic consoles but has not tested every title and does not guarantee operation or after-sales support. DLC, online services, and codes may still have regional requirements.
Do I need to change my Switch region to play a Japanese cartridge?
Usually not. Leave System > Region unchanged and test the cartridge after setting the console language you want. Changing the console region is separate from changing the language and does not translate a Japanese-only game.
Can I use a Japanese eShop code on my US Nintendo Account?
Nintendo’s Japan eShop guidance says Japan-issued download and prepaid cards require a Nintendo Account whose country/region is set to Japan. A US account should not be assumed to redeem a Japan-issued code. Review Nintendo’s current account rules before changing country/region.
Will an imported Japanese cartridge work on my Switch?
Nintendo says overseas physical Switch software works on consoles sold in Japan, but cautions that it has not tested every title and cannot guarantee operation or after-sales service. Verify the exact cartridge, keep the seller’s return option, and check DLC and online requirements separately.
Why is my Switch in English while the Japanese game is still Japanese?
The game release probably does not include English, or it may require an in-game language setting documented by the publisher. Recheck the exact Japanese edition’s supported-language list. The system language cannot create a missing translation.
Does changing the console region switch my Nintendo eShop country?
No. System > Region changes the console’s selected region. Nintendo Account country/region is a separate account setting that controls regional storefront access and Japan-issued code redemption.
The Bottom Line
Set System Settings > System > Language to English or Japanese and restart, but expect the game to use that language only when the exact release supports it. A console-region change is separate and usually unnecessary for a Japanese cartridge. Physical imports often run across regions with Nintendo’s limited testing and support guarantee, while Japan eShop purchases and prepaid codes require a Nintendo Account set to Japan.
