Media Law in Japan
The Constitutional Framework
The legal regulation of the media in Japan is anchored by Article 21 of the Constitution of Japan (1946), which provides: “Freedom of assembly and association as well as speech, press and all other forms of expression are guaranteed. No censorship shall be maintained. The secrecy of any means of communication shall not be violated.” Article 21 establishes two distinct but interrelated guarantees: the substantive freedom of expression (including press freedom) and the prohibition of prior restraint (the “no censorship” clause). The latter provision is one of the strongest prohibitions of censorship in any constitutional instrument: unlike the First Amendment to the United States Constitution, which has been interpreted to permit prior restraints in exceptional circumstances (such as national security), Article 21’s categorical language has led Japanese courts to apply a more stringent standard to any form of pre-publication restraint.
The constitutional guarantee of press freedom has been interpreted by the Supreme Court to apply to all media — traditional print journalism, broadcasting, and, since the Kiyomoto decision (2019), digital and online media — but the Court has also recognised that the freedom is not absolute. In the Hoppo Journal Case (1986), the Supreme Court articulated the standard of review for restrictions on expression: a restriction is constitutional only if it is “necessary to achieve a compelling public interest” and the means employed are “reasonable and proportionate” — a formulation that approximates the American strict scrutiny standard, though its application in practice has been uneven.
The Broadcasting Act and the Dual System
The Broadcasting Act (Hoso Ho, Law No. 132 of 1950) establishes the framework for broadcast regulation in Japan. The Act, extensively revised in 2014 and again in 2022, reflects the post-war compromise between the American model of commercial broadcasting and the European model of public service broadcasting. The Act creates a dual system: the Japan Broadcasting Corporation (NHK, Nippon Hoso Kyokai) as the statutory public broadcaster, funded by licence fees paid by every household with a television receiving set, and private commercial broadcasters licensed by the Ministry of Internal Affairs and Communications (MIC).
NHK is governed by a Board of Governors appointed by the Prime Minister with the consent of both Houses of the Diet. The Broadcasting Act requires NHK to broadcast programmes that “contribute to the sound development of democracy” (Article 1) and to maintain “political impartiality” (Article 4). The 2014 amendments, enacted in response to controversy over NHK’s editorial independence, strengthened the Minister’s powers to oversee NHK’s compliance with its statutory obligations and introduced requirements for NHK to report on its “management plans” to MIC. Critics argued that these amendments undermined NHK’s editorial independence and exposed the public broadcaster to political pressure; the 2022 amendments partially reversed these changes by strengthening the independence of the Board of Governors.
Private broadcasters operate under licences issued by MIC for renewable five-year terms. The licensing process, and the Ministry’s authority to set conditions on broadcast content, has been criticised as inconsistent with the constitutional prohibition on censorship. In practice, however, MIC has rarely revoked or refused to renew a licence on content grounds, and the principal constraints on private broadcasters come from industry self-regulation through the National Association of Commercial Broadcasters (Minso) and the Broadcasting Ethics and Program Improvement Organization (BPO), an independent industry watchdog established in 1997. The BPO reviews complaints about broadcast content and issues non-binding opinions, which broadcasters are expected to respect but which carry no legal sanction.
The Press Club System
A distinctive feature of Japanese media law and practice is the press club system (kisha club), an institutional arrangement under which accredited journalists from major media organisations receive privileged access to government and corporate press conferences, briefings, and information sources. The press clubs are organised around every major institution of government — the Prime Minister’s Office, each ministry, the Diet, the courts, the national police agency, and each prefectural government — and membership is restricted to reporters from established media organisations who meet the club’s criteria.
The press club system has been the subject of sustained criticism from domestic and international media freedom advocates on several grounds. First, the system excludes non-mainstream media, including freelance journalists, bloggers, and foreign correspondents who do not meet the clubs’ criteria, creating a two-tier system of access to official information. Second, the system encourages homogeneity of reporting — club members share information through a practice known as nemawashi (consensus-building), and journalists who deviate from the club consensus risk losing access. Third, the system fosters self-censorship: reporters who cultivate close relationships with their official sources are reluctant to publish stories critical of those sources. The Supreme Court has not ruled directly on the constitutionality of the press club system, though in the Asahi Shimbun Case (1978), the Court suggested that the denial of access to a press club might infringe press freedom if it were arbitrary, but the Court has not articulated a standard for distinguishing permissible from impermissible exclusion.
Defamation Law
Defamation in Japan is regulated under both the Penal Code and the Civil Code. Criminal defamation is proscribed by Articles 230 and 231 of the Penal Code: Article 230 punishes the public allegation of facts that harm a person’s reputation, while Article 231 punishes public insult (defamation without the allegation of specific facts). The penalties for criminal defamation include imprisonment with labour (up to three years for defamation, up to 30 days for insult) and fines.
The 2022 amendment to Article 231, enacted in response to the Supreme Court’s judgment in the Insult Penalty Case (Reiwa 3 (A) No. 1324, 2022), raised the maximum penalty for insult from 30 days’ detention to one year’s imprisonment with labour (or a fine of up to ¥300,000). The amendment was driven by concerns about the proliferation of anonymous online insults and the inadequacy of the previous penalty (30 days’ detention) as a deterrent. The Supreme Court had previously held, in the Saitama Insult Case (2021), that the existing penalty of 30 days’ detention was proportionate to the gravity of the offence — a decision that the Diet effectively reversed through the legislative amendment.
The truth-based defence in criminal defamation cases is provided by Article 230-2, which exempts from punishment statements of fact that are true and that are made “for the public interest” and “with the primary purpose of serving the public benefit.” The Supreme Court’s decision in the Yamagishi Case (2013) clarified that the public interest requirement applies not only to the subject matter of the statement but also to the manner in which it was made: a statement that would otherwise qualify as true and of public interest loses its protection if it was made in a manner disproportionate to the purpose served.
Civil defamation is governed by Article 709 of the Civil Code (the general tort provision) and Article 710 (damages for non-pecuniary harm). The standard for civil defamation is similar to the criminal standard: the plaintiff must prove the publication of a defamatory statement that has injured his reputation; the defendant may avoid liability by proving the truth of the statement and that it was made for the public interest. Japanese courts award damages for defamation on a scale substantially lower than in Anglo-American jurisdictions: awards in the range of ¥1 million to ¥5 million (approximately US$7,000 to US$35,000) are typical for defamation of an individual, with higher awards reserved for cases involving egregious misconduct by media organisations. The courts also have the power to order retraction or correction under Article 7 of the Act on the Correction of Publication (Shuppanbu Teisei Ho), though this remedy is rarely granted.
The leading defamation case is Goto v. Yamaguchi (Supreme Court, 1966), in which the Court established the standard for evaluating defamatory statements about public figures: the plaintiff must prove that the statement was false or that the defendant knew or should have known of its falsity. This standard — which approximates the American New York Times v. Sullivan actual malice standard — was confirmed and clarified in the Weekly Post Case (Supreme Court, 2013) on magazine defamation. The Court held that the public figure standard applies to statements concerning “matters of public concern” and that the defendant bears the burden of proving that the statement was made in the reasonable belief that it was true.
Protection of Journalistic Sources
Japan does not have a statutory source protection privilege for journalists. The Code of Criminal Procedure contains no provision comparable to the journalist’s privilege recognised in some American states or the qualified protection available under Article 10 of the European Convention on Human Rights. However, some courts have recognised a qualified right to protect sources in civil proceedings, relying on Article 197 of the Code of Civil Procedure (which permits witnesses to refuse to give testimony that would disclose a professional secret) and the concept of press freedom under Article 21 of the Constitution.
In the NHK Source Disclosure Case (Tokyo District Court, 2005), the court held that a journalist could not be compelled to disclose the identity of a confidential source unless the party seeking disclosure demonstrated that the information was unavailable through other means and that the need for disclosure outweighed the public interest in protecting journalistic sources. This decision, while limited to the facts of the case, has been cited by subsequent decisions as establishing a balancing test for source protection. The absence of a clear statutory shield remains a significant concern for journalists in Japan, particularly in the context of criminal investigations where prosecutors have sought to compel journalists to disclose sources.
Preliminary Injunctions Against Publication
The constitutional prohibition on censorship (Article 21) has been interpreted by the Supreme Court to prohibit prior restraint — judicial or administrative orders that prevent publication before it occurs — except in the “narrowest of circumstances.” In the foundational Hanaoka Case (Supreme Court, 1969), the Court held that an injunction against publication of a magazine article was unconstitutional because the government had not demonstrated that the publication threatened a “clear and present danger” of irreparable harm. The Court applied the same standard in the Yamagishi Case (1986), striking down an order restraining the publication of a book on the grounds that the applicant had not shown that the harm from publication would be “grave and irreparable.”
Despite the strict standard articulated by the Supreme Court, lower courts have occasionally granted preliminary injunctions (kari-sho bunkatsu) against publication, particularly in cases involving alleged defamation of political figures. In the Shukan Shincho Case (Tokyo District Court, 2004), the court granted an injunction against the publication of an article concerning the extramarital relationship of a Diet member, finding that the invasion of privacy outweighed the public interest in publication. The decision was controversial and was reversed on appeal, but it illustrates the continuing tension between the constitutional prohibition on prior restraint and the willingness of some courts to protect privacy through injunctive relief.
The Right to Be Forgotten
The Supreme Court’s 2017 decision in the Nagoya Case (the Right to Be Forgotten case) established the framework for claims seeking the delisting of information from search results. The case concerned an individual who had been arrested for child pornography offences; the criminal charges had been dropped, but news reports of his arrest continued to appear in search results for his name. The plaintiff sought an injunction requiring Google to remove the search results.
The Supreme Court held that the right to be forgotten is not a freestanding right under Japanese law, but that an individual may seek an injunction to delete search results where the information interferes with his right to privacy and where the interest in protecting his privacy outweighs the public interest in access to the information. The Court articulated a multi-factor balancing test: the nature of the information (whether it concerns criminal conduct, the seriousness of the offence, the time elapsed since the event, and whether the individual is a public figure), the harm to the individual, and the public interest in the information remaining accessible. In the Nagoya Case itself, the Court held that the plaintiff’s interest in privacy outweighed the public interest because the charges had been dropped, the offence was not of the highest gravity, and a significant period (approximately five years) had elapsed.
The Nagoya decision has been applied by lower courts in subsequent delisting cases, with outcomes varying according to the facts. The Tokyo District Court has granted delisting orders in cases involving minor criminal convictions from decades past but has denied delisting where the information concerns ongoing public debate or where the plaintiff continues to hold public office.
Election Media Regulation
The Public Offices Election Act (Koshoku Senkyo Ho) imposes strict limitations on election-related media. The Act prohibits the publication of election polls during the campaign period (other than by officially recognised media organisations), restricts the distribution of election materials to government-approved formats, and limits the content of election broadcasts. The Supreme Court has upheld these restrictions as necessary to ensure the fairness and integrity of elections, rejecting challenges under Article 21. The Asahi Shimbun v. Election Commission case (1982) upheld the prohibition on the publication of exit polls before the close of voting, a restriction that the Court found justified by the compelling interest in preventing voter confusion.
Online Platform Regulation
The regulation of online media is governed by the Act on the Provider Liability Limitation (Purobaida Sekinin Seigen Ho, Law No. 137 of 2001), which establishes a framework for the liability of internet service providers and platform operators for content posted by users. Under the Act, a provider is not liable for damages arising from the publication of defamatory content unless it knew or had reason to know of the content and failed to take reasonable steps to remove it. The Act also establishes a notice-and-takedown procedure: a person who claims to have been defamed may notify the provider, who is then obliged to remove the content or risk liability. The revised Act on the Protection of Personal Information (Law No. 57 of 2003, as amended in 2015 and 2020) imposes obligations on online platforms regarding the handling of personal data, with fines for non-compliance.
The tension between the protection of personal information and the freedom of expression on online platforms remains a central issue in Japanese media law, with the courts continuing to develop the balance between privacy and speech in the digital environment on a case-by-case basis.
