Anyone who reads raw manga eventually runs into the question. You bought a volume from a Japanese store, you can't read Japanese, and a translation tool is right there. Is that allowed?
The answer depends almost entirely on two things that have nothing to do with translation itself. This guide covers what those are, how fair use applies, why scanlation occupies the position it does, and what changes when an AI tool is involved.
This is general information rather than legal advice. Copyright law varies by country, and specific situations warrant professional guidance.
Is it legal to translate manga you bought?
For personal reading, generally yes, with qualifications.
Translation is legally a form of derivative work, and the right to create derivative works belongs to the copyright holder. That sounds like it settles the matter, but most jurisdictions carve out space for private, non-commercial use.
In the United States, this falls under fair use. In the UK it's the private study and research exception. Japan's Article 30 permits reproduction for private use. The specifics differ, but the shared principle is that copying for your own use, without distribution, is treated differently from copying for others.
What matters practically is that the output stays with you. A translated file sitting on your own drive, read by you, is in defensible territory in most places. The moment it leaves, a different analysis applies.
What counts as personal use?
Narrower than most people assume.
Personal use generally means you, and in some jurisdictions your immediate household. It does not scale with good intentions. Sharing with a friend sits in genuinely ambiguous territory. Posting to a Discord server, a subreddit, or any group chat is past the line, because those constitute distribution to the public regardless of group size or privacy settings.
The most common misconception is that not charging money keeps something within personal use. It does not. Commercial intent is one factor among several, and free distribution can affect a rights holder's market more directly than paid infringement, since free is a more attractive substitute than a paid alternative.
Is scanlation legal?
No. Unlicensed scanlation does not survive a fair use analysis, and it's worth walking through why, because the reasoning clarifies the personal-use case too.
US fair use weighs four factors:
1. Purpose and character of the use. Fair use favors transformative work such as commentary, criticism, or parody. A faithful translation meant to be read in place of the original is substitutional rather than transformative. Translation is explicitly among the derivative work rights reserved to the copyright holder.
2. Nature of the copyrighted work. Manga is creative expression, which receives stronger protection than factual or functional work. This factor weighs against.
3. Amount and substantiality used. Scanlation typically reproduces entire chapters or volumes. There is no favorable reading of this factor when the whole work is used.
4. Effect on the market. Courts weigh this most heavily. Freely distributed translations substitute directly for official releases, which is precisely the harm this factor addresses.
Four factors, four unfavorable outcomes. Common scanlation norms such as dropping a series once it's licensed, never charging, or posting takedown notices reflect a community acting in good faith, but none of them alter the legal analysis.
Why has scanlation been tolerated for so long?
Because enforcement is a business decision rather than a legal verdict.
Cross-border litigation is expensive. Scanlation groups typically hold no assets worth pursuing. And for a series with no license in a given language, a fan translation does not displace sales that do not exist. During that window, publishers have at times benefited from the exposure, since demonstrated demand informs licensing decisions.
This is tolerance, not permission, and the difference becomes visible the moment a license is signed. Takedown requests usually follow shortly after. Readers who spent years in an unenforced space often experience this as rules changing, when in fact the rules were always present and simply unexercised.
Japanese publishers have also grown considerably more active against large aggregator sites in recent years, with meaningful consequences for operators. The window of tolerance has been narrowing rather than widening.
Does using an AI tool change anything?
Legally, no. The analysis is identical whether someone translates with a dictionary, a phone app, or a specialized model. The output is a derivative work either way, and what determines the outcome is source and distribution, not method.
Practically, one thing has changed: friction. Translating a chapter manually required hours of cleaning, translation, and typesetting. That cost functioned as a natural limit on volume. Modern tools compress the same work into minutes.
The relevant consequence is that the distance between reading something and having a distributable file has collapsed. The pause that used to exist, where someone might reconsider, has largely disappeared. That makes the distinction between personal use and distribution worth holding deliberately rather than by default.
The two questions that determine everything
Strip away the surrounding debate and it reduces to this:
How was the source obtained? Purchased from a Japanese ebook store, read through an official platform, or bought physically. Or downloaded from an aggregator site.
Where did the output go? Your own screen. Or anywhere else.
Legally obtained source plus no distribution sits in defensible territory nearly everywhere. Either condition failing changes the analysis, and both failing removes any argument.
Where to buy raw manga legally
Series without a translation in your language are still available through legitimate channels.
BOOK☆WALKER operates an international storefront selling Japanese-language titles, with a broad catalog and regular sales.
Amazon Kindle's Japanese store sells to international customers, though account setup can require some configuration.
Shonen Jump+ and comic-walker offer free and paid chapters, in some cases simultaneously with Japanese release.
Official platforms in your region are worth checking first. If a title is licensed where you are, reading the official version is simpler and directly supports further licensing.

Frequently asked questions
Is it illegal to read raw manga?
Reading is not the issue. Obtaining a copy through an unauthorized source is a separate question from reading it, and the two are often conflated. Purchasing or accessing manga through official channels and reading it, in any language, is straightforward.
Can I translate a manga I bought and keep the file?
For personal reading, generally yes under private use provisions in most jurisdictions. The file should not be shared or uploaded.
Is it legal to translate manga if I don't share it?
This is the core of the personal use case, and it's where the legal position is strongest. The absence of distribution removes the market harm that drives most infringement analysis.
Can I post translated pages if I credit the author?
Attribution does not create permission. Credit is a norm in some communities but has no bearing on copyright. Distribution remains distribution.
Is scanlation illegal even if it's free?
Yes. Non-commercial status is one factor among several and does not override the others, particularly market effect.
What about a manga that will never be licensed in English?
The absence of a license does not transfer rights to readers. It does mean enforcement is less likely, which is a practical observation rather than a legal one. Buying the Japanese release and translating it for personal reading remains available.
Does translating with AI count as creating a derivative work?
Yes. The method used does not affect the classification.
What about series the author posts freely on social media?
Free publication by the creator does not waive copyright. Some creators explicitly permit translation and redistribution, in which case their stated terms apply. Absent a clear statement, the default remains that redistribution is not permitted.
Summary
Translation tools remove a language barrier. They do not create a right to access a work that wasn't obtained legitimately, and they do not convert distribution into personal use.
Obtain the source legitimately, keep the output to yourself, and the majority of the legal complexity here does not apply.
