Japan's newly enacted law criminalising the desecration of its national flag has ignited a legal and political debate over the limits of free speech, with human rights organisations warning that the legislation threatens constitutionally protected expression and contravenes international human rights standards.

The controversy comes just days after Japan's parliament approved a broader package of political reforms, including amendments to the country's referendum framework, reflecting the government's growing emphasis on constitutional and national identity issues.

Human Rights Watch (HRW) has urged the Japanese government to repeal the flag desecration law, arguing that it criminalises symbolic political expression and risks suppressing peaceful protest. According to the organisation, the legislation is incompatible with Japan's obligations under international human rights law, particularly the right to freedom of expression protected by the International Covenant on Civil and Political Rights (ICCPR).

The new law

The legislation makes it a criminal offence to publicly damage, remove or deface Japan's national flag, the Hinomaru, in a manner considered likely to cause "extreme discomfort" or "disgust" to others.

Individuals found guilty face penalties of up to two years' imprisonment or a fine of ¥200,000 (approximately US$1,300). The law also extends to acts broadcast through livestreams or uploaded online where the conduct is deemed offensive to the public.

The measure fulfils a long-standing policy objective of Prime Minister Sanae Takaichi and her governing Liberal Democratic Party, which had unsuccessfully sought similar legislation on previous occasions.

Supporters argue that Japan should criminalise desecration of its own national flag just as it already prohibits the desecration of foreign national flags in certain circumstances to prevent diplomatic disputes.

Human rights concerns

Human Rights Watch contends that the law goes far beyond protecting a national symbol.

Instead, it argues that the legislation effectively criminalises symbolic political speech, a form of expression that enjoys strong protection under international human rights law.

Article 19 of the ICCPR guarantees the right to freedom of expression, including the freedom to impart ideas through symbolic acts such as flag burning or other peaceful demonstrations. While governments may impose restrictions to protect public order or national security, those limitations must be lawful, necessary and proportionate.
