DeepTranslateYouTube Comment Translation Guide: How to Read Foreign Language Comments in Japanese
When watching international YouTube videos, sometimes the comment section is more entertaining than the video itself. The comments section gathers genuine opinions from users worldwide, including reactions from English-speaking viewers, the vibe of K-pop and VTuber international fans, game commentary reactions, and reviews of AI tools and gadget videos.
However, YouTube comment translation is different from subtitle translation. Even if video subtitles can be translated, you often find that the translation button for comments doesn't appear, there are too many foreign language comments to translate one by one, or the meaning of slang and emojis is unclear.
This article will explain what YouTube comment translation can do, reasons why it might not work, its differences from subtitle translation, and how to display comments bilingually with the original text in Japanese using DeepTranslate.
First, the Conclusion: What YouTube Comment Translation Can and Cannot Do
Foreign language comments on YouTube can sometimes be translated using standard features, depending on the situation. YouTube officially provides information on supported languages for YouTube comments, and features are being developed to allow reading and writing comments in multiple languages on YouTube.
However, a translation link doesn't always appear for all comments. The appearance can vary based on the displayed language, account settings, differences between browsers and apps, and YouTube's updates.
| What you want to do | YouTube Standard Feature | DeepTranslate Suitability |
|---|---|---|
| Roughly read one comment | Sometimes available | Usable, but might be overkill |
| Read the entire comment section at once | Cumbersome | Well-suited |
| Compare original text with Japanese translation | Depends | Well-suited |
| Alternative when translation button doesn't appear | Weak | Easy to use as an alternative on Chrome |
| Real-time translation of live chat | Different purpose | Should be handled on a dedicated page |
The key is not to think of YouTube comment translation as a "one-by-one translation task." The purpose of reading international comment sections is not just to understand the meaning of words, but to grasp the overall atmosphere, reactions, jokes, evaluations, and conversations among fans.

YouTube Subtitle Translation, Title Translation, and Comment Translation Are Different
When people hear "translation" on YouTube, they often think of subtitle translation. However, video subtitles, titles, descriptions, comment sections, and live chats are all distinct areas.
| Area to translate | Main purpose | Caveats |
|---|---|---|
| Subtitles | Understand spoken content of the video | Depends on the accuracy of automatic subtitles |
| Title/Description | Grasp video content | YouTube's automatic translation may appear |
| Comment section | Read viewer reactions and conversations | Translation link may not appear |
| Live chat | Follow reactions during a live stream | High volume, strong real-time nature |
| Reply threads | Read responses to comments | Lots of slang, abbreviations, inside jokes |
YouTube's official translation tools primarily relate to video metadata and subtitle translation. However, if you want to read the comment section, YouTube's standard display might not be sufficient.
Therefore, this article focuses on comment section translation, not subtitle translation.
Basic Methods to Translate YouTube Comments into Japanese
There are two main ways to read YouTube comments in Japanese.
Use YouTube's Standard Translation Link
If a translation link appears below a comment, you can simply click it to see the Japanese translation. For reading a few short comments, this method can be sufficient.
However, it can be inconvenient in the following cases:
- The translation link does not appear.
- There are many comments, and clicking each one is tedious.
- You want to read entire reply threads.
- You want to compare the original text with the Japanese translation.
- Comments in languages other than English are mixed in.
Read the Entire Comment Section with a Chrome Extension
If you want to read the entire comment section, it's more efficient to translate the whole page using a Chrome extension. When using DeepTranslate, keep the YouTube page open and open the translation panel from the extension toolbar in the top right of your browser.
Set the translation target to Japanese and execute the web page translation. This makes it easier to read English comments in Japanese. The original text also remains, making it easier to check the nuances of slang, proper nouns, and emojis.
Reading the comment section as a whole allows you to see not just individual comments, but also replies, likes, recurring opinions, and the general sentiment of international users. This is a more important point than simply "being able to translate."

Reasons Why YouTube Comment Translation Might Fail or Not Appear
Many people search for "YouTube comments not translating" or "YouTube comments translation not showing." The cause is not just one thing.
Common patterns are as follows:
| Symptom | Possible Cause | Direction for Solution |
|---|---|---|
| Translation link doesn't appear | YouTube's judgment, language settings, comment content | Try a different browser, reload, or an extension |
| Translates to a different language instead of Japanese | Account or browser language settings | Check YouTube and Google account language settings |
| Appears on app but not on PC | Device or UI differences | Use an extension on PC Chrome |
| Only some comments aren't translated | Too short, emoji-centric, difficult language detection | Check original text, use another tool for assistance |
| Used to appear but disappeared | YouTube update or temporary glitch | Wait, try a different browser |
Japanese SERPs also contain pages addressing issues with YouTube comments not translating. For example, YouTube comment translation consultation and Pajoca's article dealing with comments translating to a different language.
DeepTranslate does not change YouTube's internal functionality itself. However, even when YouTube's standard translation link is not visible, it can be used as an alternative route to translate the page open in Chrome.
Expressions to Watch Out for When Reading International User Comments
In YouTube comment sections, you'll often find short reactions, slang, emojis, and abbreviations rather than textbook English. A literal translation alone might not convey the true sentiment.
| Expression | Pitfall of Literal Translation | Meaning in Comment Section |
|---|---|---|
| lol / lmao | Looks like just laughter | Laughing, light-hearted joking |
| fr | Meaning is unclear | For real, truly, seriously |
| ngl | Looks like a decorative phrase at the beginning of a sentence | Not gonna lie, to be honest |
| based | Often translated as "based on" | Good opinion, principled, supportive |
| W / L | Looks like just letters | Win / Loss, good/bad evaluation |
| ratio | Looks like a numerical ratio | Internet context of being outmatched in arguments or reactions |
| GOAT | Not an animal | Greatest Of All Time, a compliment meaning the best |
When reading YouTube comments, keeping the original text alongside the Japanese translation makes it easier to interpret such expressions. Reddit also has user posts about comment translation not working well or not translating, highlighting the uncertainty of relying solely on platform-side automatic translation. For example, there are discussions like comments not being translated.

Tips for Translating and Replying to Comments
If you want to reply to international users, you need to check not only the translation but also whether it sounds natural as a public comment. YouTube's official guide on how to post and reply to comments on YouTube also explains the basics of commenting and replying.
Things to check before replying:
- Have you misunderstood the other person's comment?
- Are you taking sarcasm or jokes seriously?
- Have you checked the meaning of emojis and abbreviations?
- Is your reply too strong in tone?
- Are you writing personal information or content you don't want to make public?
For short replies, there's no need to force a long message. Simple English phrases like Thanks!, I agree, That helped a lot, or I was thinking the same thing can often be sufficient.
If you are a creator or channel operator, in addition to replying to comments, checking YouTube's comment settings can help you understand comment management and visibility.
YouTube Comment Translation Tool Comparison
YouTube comment translation includes standard features, comment-specific extensions, and general web page translation tools.
| Method | Suitable Scenario | Pros | Cons |
|---|---|---|---|
| YouTube Standard Translation | Reading a few comments | No additional tools needed | May not appear, difficult for bulk reading |
| Comment-specific Extension | Efficient for YouTube comments only | Clear purpose | Behavior and permission checks vary by tool |
| DeepTranslate | Entire comment section, international reactions, other sites | Easy to translate entire web pages, easy to check original text | May be overkill for those who only need YouTube-specific features |
The Chrome Web Store offers comment-specific tools like YouTube Comment Translator. Articles like Napolitan Sushi's YouTube Comment Translate Explanation also introduce how to use single extensions.
However, if you read not only YouTube but also Reddit, X, international news, official announcements, and forums, DeepTranslate, which can translate entire web pages, is more versatile than a comment-specific tool.
Read international comments beyond YouTube in bulk
DeepTranslate can translate not only YouTube comment sections but also Reddit, international forums, and news articles with original text.
FAQ
Can I translate YouTube comments on my phone?
Translation links may appear in the YouTube app or mobile browser. However, the display and behavior vary depending on the environment. Using a Chrome extension is generally easier on the PC version of Chrome.
Why are YouTube comment translations not showing?
Possible reasons include YouTube's language detection, account or browser language settings, comment content, UI changes, or temporary glitches. If standard features don't appear, you can try translating the entire page with a Chrome extension.
Can YouTube live chat also be translated?
Live chat is different from regular comment sections; it's fast-paced and highly real-time. It's difficult to read with the same approach as static video comment sections, so it's recommended to consider it as a separate workflow.
Are YouTube subtitle translation and comment translation the same?
No, they are different. Subtitle translation is for understanding spoken content in videos, while comment translation is for reading viewer reactions and conversations. The search intent and features used are also different.
Is it okay to only use translation tools when replying to foreign language comments?
For short replies, translation tools can be sufficient. However, when replying to sarcastic, joking, argumentative, or critical comments, it's safer to check the nuance of the original text before posting.
Summary: YouTube Comment Translation is a Tool for Understanding International Reactions
YouTube comment translation is not just a function to convert English to Japanese. It's a way to understand international users' reactions, conversations among fans, video evaluations, and the sentiment conveyed through slang and emojis.
For reading just a few comments, YouTube's standard translation link might be sufficient. However, if you want to read the entire comment section at once, compare original text with Japanese translation, or need an alternative when the translation button doesn't appear, a Chrome extension-based web page translator like DeepTranslate can be very helpful.
