The Japanese House of Representatives Cabinet Committee approved a bill on June 26, 2026, that criminalizes the public desecration of the national flag [1], [2].

The legislation marks a significant shift in how Japan handles national symbols, moving toward criminal penalties for acts that were previously managed through social norms or different legal frameworks. Supporters argue the move is necessary to protect national dignity, while critics warn it could infringe upon constitutional freedoms of expression.

The bill was jointly proposed by the Liberal Democratic Party, the Nippon Ishin no Kai, the Democratic Party for the People, and the Sanseito [2]. It also received support from Team Mirai [2]. In total, five political parties supported the measure [2].

Under the proposed law, individuals found guilty of publicly damaging the national flag could face up to two years of imprisonment or a fine of up to 200,000 yen [2].

During the committee proceedings, lawmakers debated the specific definitions of desecration. Rep. Goto (Centrist Reform Union) asked whether writing "Go Japan" in large black marker would actually qualify as an act that causes significant discomfort or disgust [1].

Rep. Shiozaki (LDP) said the content of the written words does not change the legal requirements for the offense. Shiozaki said using a thick black marker to write on the flag is a method that causes people to feel significant discomfort or disgust [1].

Opposition to the bill came from two political groups: the Centrist Reform Union, and the Japanese Communist Party [2]. These parties argued that the law could lead to constitutional violations and the suppression of political expression, which they claim is a fundamental right in a democratic society.

The bill now moves forward in the legislative process following its passage through the Cabinet Committee [1], [2].

“individuals found guilty of publicly damaging the national flag could face up to two years of imprisonment”

The passage of this bill reflects a growing trend toward legal nationalism within Japan's governing coalition. By establishing criminal penalties for flag desecration, the government is prioritizing the symbolic integrity of the state over absolute freedom of expression. This creates a legal precedent that may lead to further restrictions on political protests if the definition of 'discomfort' remains broad and subject to judicial interpretation.
