How Many Characters Can You Quote? Copyright Rules for Quoting Text and Lyrics
The short answer: no copyright law defines a character count up to which quoting is automatically legal. Whether a quotation is lawful depends on requirements and context, not on length. A 100-character quote can infringe, while a several-hundred-character quote can be perfectly legal. This article walks through Japan's statutory quotation rule (Article 32 of the Copyright Act) and the U.S. fair use doctrine, and untangles the common word-count myths.
This article is general information, not legal advice. Consult a professional for specific cases.
Direct Answer: There Is No Statutory Character Limit
Article 32(1) of the Japanese Copyright Act permits quotation of published works, on the condition that the quotation is "compatible with fair practice" and stays "within a scope justified by the purpose of the quotation, such as news reporting, critique, or research." That is the entire quantitative guidance: none. Rules of thumb circulating online - "up to 10% is fine," "three lines are safe" - have no legal basis in Japan, and the same is true of the "300 words is always fair use" myth in the United States.
Requirements for a Lawful Quotation (Japan)
Japanese courts, most influentially the Supreme Court's March 28, 1980 decision (the "parody montage photo" case), have distilled the statute into practical requirements:
| Requirement | What It Means | Basis |
|---|---|---|
| Published work | Unpublished letters or manuscripts cannot be quoted | Art. 32(1) |
| Clear distinction | Quotation marks or block quotes make the quoted part visually separate from your own text | Supreme Court, Mar. 28, 1980 |
| Master-servant relationship | Your own text is the "master," the quote the "servant" - judged in both quantity and substance | Same decision |
| Necessity / justified scope | A context (reporting, critique, research) that actually requires the quote | Art. 32(1) |
| Source attribution | Author and title indicated according to fair practice | Art. 48 |
| No alteration | Do not distort the original by silent edits or re-lineation | Art. 20 (integrity right) |
Character count is not a direct criterion, but it enters indirectly through the master-servant test: if your commentary is 200 characters and the quote is 2,000, the quote is quantitatively no longer subordinate. So length is "not the rule, but evidence for the rule."
The U.S. Angle: Fair Use Has No Word Count Either
In the United States, quotation is analyzed under fair use (17 U.S.C. §107), which weighs four factors: (1) the purpose and character of the use, (2) the nature of the copyrighted work, (3) the amount and substantiality of the portion used, and (4) the effect on the market for the original. Factor 3 explicitly considers "amount" - but as a proportion and in relation to the heart of the work, not as a fixed word count. Quoting a few lines that constitute the creative core of a short poem can weigh against fair use, while quoting several paragraphs of a long book for critique can weigh in favor. No statute or court has ever blessed a universal safe number.
Case by Case: Does This Count as Quotation?
| Scenario | Likely Treatment | Key Point |
|---|---|---|
| A book review quoting a passage to critique it | Lawful if requirements are met | Is the review the master and the quote the servant? |
| A "famous quotes" collection page | Hard to justify as quotation | No own text - the relationship is inverted |
| One lyric line inside a critique | Lawful if requirements are met | Short works make "justified scope" stricter |
| Posting full lyrics on a blog or social media | Reproduction, not quotation - permission needed in principle | Blanket-licensed platforms change the picture (below) |
| Copying a full news article | Reproduction, not quotation | Summarize in your own words and link instead |
| Embedding an X (Twitter) post via the official embed | Use under the platform's terms | Different from pasting a screenshot |
The unifying question is: "Is my own content the main act, with the quote as supporting material?" On platforms with tight character limits like X, there is often too little room to write the "master" commentary at all - which is exactly why lyric-posting disputes cluster on short-form social media.
Why Lyrics Are the Strictest Case
A full song lyric is typically only 350-700 characters in Japanese - as measured in our karaoke lyrics character count article - so even "one phrase" is a large fraction of the whole work. That makes the justified-scope analysis much stricter than for prose.
In Japan, JASRAC (the largest music rights society) maintains blanket license agreements with major UGC platforms. On covered services, individual users can post lyrics of JASRAC-managed songs without their own paperwork, within non-commercial use. The official list (updated April 2026) includes video platforms such as YouTube, Niconico, TikTok, and Instagram, and blog services such as Ameba Blog, Hatena Blog, Seesaa Blog, and Rakuten Blog. Posting full lyrics on a non-covered service or your own website requires the rights holder's permission in principle.
Quotation vs. Reproduction, in Character Terms
Quotation (no permission needed when requirements are met) and reproduction (permission needed) are legally distinct. The boundary is not drawn at a character count, but a practical smell test works well: if removing the quoted text would collapse your article, you are drifting toward reproduction. If your argument still stands on its own without the quote, the master-servant relationship is healthy. You can sanity-check the balance between your own text and quoted text with the Character Counter.
Common Mistakes and Safer Alternatives
| Risky Behavior | Why It Fails | Safer Alternative |
|---|---|---|
| "I cited the source, so anything goes" | Attribution is only one requirement of several | Also check necessity and the master-servant balance |
| Quotes longer than your own text | Quantitative subordination collapses | Trim quotes to the essential lines; expand your commentary |
| Silently editing or trimming the original | Integrity right risk | Mark omissions explicitly ("[...]") |
| Full lyrics plus a one-line comment | Treated as reproduction, not quotation | Use a blanket-licensed platform, or quote only a fragment |
When in doubt, two working principles serve well: do not quote what your piece can live without, and whenever you quote, write more of your own words than you borrow. The law asks for structure, not a magic number.

Frequently Asked Questions
- How many characters can I legally quote?
- There is no statutory character limit. Legality depends on requirements such as quoting a published work, clearly distinguishing the quote, keeping your own text dominant, necessity, and attribution.
- Is quoting 300 words always fair use in the US?
- No. That figure is a myth. Fair use weighs four statutory factors, and the amount used is judged as a proportion of the work and whether it takes its creative core, not against a fixed count.
- If I credit the source, can I post anything?
- No. Attribution is only one requirement among several. Without the master-servant balance and necessity, credited copying can still infringe.
- Can I post full song lyrics on my blog?
- On platforms with a JASRAC blanket license (such as Ameba Blog or Hatena Blog in Japan) individuals can post lyrics of managed songs non-commercially without paperwork. Elsewhere, permission from the rights holder is required in principle.
