DeepTranslateHow to Change Twitter/X from English to Japanese: iPhone, PC, and Post Translation Differences
You open Twitter/X and find the menu in English, showing "Home," "Explore," "Settings and privacy," etc. Or perhaps you want to read English posts or threads in Japanese. In such cases, common searches include twitter English to Japanese or twitter language settings English to Japanese.
However, there's an important distinction to make from the start: changing X's display language to Japanese and translating the content of English posts into Japanese are separate settings.
When you change the display language back to Japanese, menus and buttons will appear in Japanese. However, this doesn't automatically translate all English posts appearing in your timeline. If you want to read English posts, threads, replies, or profile descriptions in Japanese, you'll need to use X's translate button, browser translation, or a page translation tool like DeepTranslate.
First, Confirm: Display Language and Post Translation Are Different
Even X's official help, How to change language settings, explains that the display language changes the headings, buttons, and menus of X. This means that even if you set the language to Japanese, content posted in English will not automatically be fully translated into Japanese.
Here's a table to clarify common points of confusion:
| What you want to do | Where to change it | What changes | What doesn't change |
|---|---|---|---|
| Change X's menu to Japanese | Display language / App language | UI elements like Home, Post, Settings | The body of English posts |
| Adjust the content tendency in your timeline | Content language settings | May affect recommended content | Translation of all post bodies |
| Read English posts in Japanese | Translate button, browser translation, extension | Post body, threads, profile descriptions | Requires checking accuracy against the original |
| Post in English after writing in Japanese | Translation tool + self-review | Draft of the post | Requires checking for nuance and polite expressions |
First, distinguish whether you want to "change the screen display back to Japanese" or "read English posts in Japanese." The former involves language settings, the latter involves post translation.
Steps to Make Recommended Content More Japanese-Centric
X has a setting for "content languages to use for recommendations," separate from the display language. This setting influences the recommendations in your timeline, people suggestions, and trends, but it does not automatically translate English posts into Japanese.
Nevertheless, if you feel there are too many English recommendations, it's worth checking this setting. First, open your profile icon in the top-left corner of the home screen.
Once the menu opens, select "Settings and privacy" at the bottom. If your display is in English, use this item name as a guide.
On the settings screen, open "Accessibility, display, and languages." This section groups settings related to display, accessibility, and language.
Next, select "Languages." This item relates to the languages used on X and for recommended content.
Open "Content languages" to choose the languages you want included in recommended posts, people, and trends on X. If you want to focus on Japanese content, check if Japanese is selected here.
Finally, turn on "Japanese - 日本語" and press "Done." If English is also turned on, you might still see English content, so adjust according to the balance of languages you want to see.
Even if you change this setting, not all English posts already displayed will be translated into Japanese. When you want to read English posts or threads, use the translate button or a translation workflow like DeepTranslate.

How to Change Twitter/X from English to Japanese on iPhone
If the X app display is in English on your iPhone, check not only the X app settings but also your iPhone's language settings and per-app language settings. Apple's official Change the language on your iPhone or iPad can also be a helpful reference for checking device-level language settings.
The basic steps to check are as follows:
- Open "Settings" on your iPhone.
- Go to "General" and check "Language & Region."
- See if your iPhone's preferred language is Japanese.
- Search for the X app within "Settings" and, if per-app language settings are available, choose Japanese.
- Close the X app completely and reopen it.
The display names might vary slightly depending on your iOS version and app status. If only the X app remains in English, also check the following:
- Is the overall iPhone language set to Japanese?
- Is the X app's preferred language not set to English?
- Is the X app updated to the latest version?
- Does it remain unchanged even after restarting the app?
- Does the web version of X.com display in Japanese?
This will only fix the X screen display. It won't translate the body of English posts into Japanese, so if you want to read post content, refer to "How to Read English Posts/Threads in Japanese" later in this article.
How to Display X.com in Japanese on PC
On PC or the browser version of X.com, you change the display language from X's settings screen. If the menu is in English, it's easier to find your way by using the English names as clues.
The general steps are as follows:
- Open X.com.
- Click "More" in the left menu.
- Open "Settings and privacy."
- Select "Accessibility, display, and languages."
- Open "Languages."
- Select "Japanese / 日本語" for "Display language."
- Save and refresh the page if necessary.
It's helpful to remember these commonly confusing menu names in English:
| English Display | Meaning in Japanese |
|---|---|
| More | もっと見る (See more) |
| Settings and privacy | 設定とプライバシー (Settings and privacy) |
| Accessibility, display, and languages | アクセシビリティ、表示、言語 (Accessibility, display, and languages) |
| Languages | 言語 (Languages) |
| Display language | 表示言語 (Display language) |
When using X on a PC, after fixing the language settings, it's easy to move on to reading English posts using browser translation or extensions. For those who frequently read international news, AI, Web3, gaming, or developer accounts, it's convenient to keep display language and post translation separate and well-organized.
How to Read English Posts and Threads in Japanese
Even if you set X's display language to Japanese, posts, threads, profiles, quoted posts, and replies written in English may still appear in English. This section discusses "translating post content."
When X's translate button appears, it might be sufficient for short posts. However, for long threads, release notes, developer-oriented posts, international news, or content with a lot of technical jargon, it's more reassuring to be able to read with the original text preserved.
When using DeepTranslate, open X.com in your browser, navigate to the post or account page you want to translate, and then use page translation. This allows you to view the Japanese translation alongside the English original, making it easier to keep track of proper nouns, feature names, numbers, and release details.
When reading English posts, check the following points:
| Common X Content | What to check |
|---|---|
| Official announcements | Date, version, target audience |
| AI/Developer info | Feature names, commands, limitations |
| Breaking news | Who said it, when was the information from |
| Game updates | Patch notes, nerf/buff, event duration |
| Web3/Financial info | Numbers, tickers, risk disclosures |
| Reply section | Sarcasm, abbreviations, context shifts |
Especially in threads, translating just one post might break the meaning. Reading it together with preceding and succeeding posts, the original source, and descriptions of attached images will reduce misunderstandings.

How to Translate Japanese Posts to English for Replies/Posts
Conversely, if you want to reply in English to an international creator, company, or official account, you'll need to translate from Japanese to English. People searching for twitter Japanese to English or twitter translate Japanese to English are likely in this situation.
When posting Japanese content in English, before posting the translation as-is, review the following points:
- Is the tone not too strong or rude to the recipient?
- Does sarcasm or jokes not unintentionally appear aggressive?
- Are proper nouns, product names, and work titles correct?
- Is the tone of requests, questions, or feedback natural?
- Is the content appropriate for a public post?
- Does it contain any personal or unreleased information?
For example, if you're reporting a bug to an official international account, it's better to be concise and specific. Directly translating emotional Japanese might sound too strong in English, so reread it after translation.
Differences Between X's Translate Button, Google Translate, and DeepTranslate
X's translate button, Google Translate, and DeepTranslate each suit different situations. Rather than one being universally correct, it's more practical to choose based on the length and context of the content you want to read.
| Method | Suitable situations | Caveats |
|---|---|---|
| X's translate button | Quickly reading short posts | Button may not appear, can be difficult to follow long contexts |
| Google Translate | Copying text to check meaning | Requires manual management of entire threads or profile flows |
| Browser's built-in translation | Roughly translating entire web pages | May be unstable with X's dynamic display |
| DeepTranslate | Reading English posts, threads, profiles, long texts with original text | Important announcements or numbers require original text verification |
| Human review | Work, PR, legal, posts with high risk of controversy | Takes time but is safer |
X is a service where features and UI can change frequently. If you can't find the translate button or display language options, checking the X Help Center for the latest help is the most reliable approach.
FAQ
Why are posts still in English even after I change Twitter/X from English to Japanese?
The display language setting changes UI elements like menus and buttons to Japanese. It does not automatically translate the entire body of posts written in English. To read post content, you need to use X's translate button, browser translation, or tools like DeepTranslate.
Where should I look if X is in English on my iPhone?
Check "Language & Region" in your iPhone's "Settings," and if necessary, also check the per-app language settings for the X app. If restarting the app doesn't help, try updating the app or checking the web version of X.com.
How do I change X.com back to Japanese on my PC?
From X.com, open "More," then "Settings and privacy," navigate to "Languages" within "Accessibility, display, and languages." There, change "Display language" to Japanese.
What if the X translate button doesn't appear?
It might not appear depending on the post type, language detection, or app/browser status. Try refreshing the page, updating the app, opening it in a browser, or using a different translation tool.
Can I read an entire English thread in Japanese?
Open X.com in your browser and use page translation while the entire thread is displayed to make it easier to read. For long threads, also check preceding and succeeding posts and the original source.
Is it okay to translate a Japanese post to English and post it as is?
For short, everyday sentences, it might be fine, but for work, complaints, official replies, negotiations, or sensitive topics, it's recommended to review the tone and meaning after translation.
The Method Changes Depending on Whether You're Fixing the Display or Reading English Posts
When you want to change Twitter/X from English to Japanese, first distinguish your goal. If you want to change the screen menus back to Japanese, check the display language settings on your iPhone or X.com. If you want to read English posts, threads, replies, or profiles in Japanese, then post content translation is necessary.
Sometimes, simply fixing the display language is enough. However, if you regularly read English posts from official international accounts, AI, Web3, gaming, or news, having a workflow that allows you to compare the original text with the Japanese translation will provide peace of mind.
