Japan’s Nagoya High Court on March 7 ruled the lack of legal recognition of same-sex marriages violates the country’s constitution. 

The plaintiffs argued Japan’s Civil Code and Family Registration Act, which does not recognize same-sex marriages, violates the country’s constitution. They cited Article 14, Paragraph 1, which guarantees equality under the law and prohibits discrimination based on factors that include race, creed, sex, or social status. The plaintiff also invoked Article 24, Paragraph 2, which emphasizes that laws governing marriage and family matters must uphold individual dignity and the fundamental equality of the sexes.

The plaintiffs sought damages of 1 million yen ($6,721.80) under Article 1, Paragraph 1, of the State Redress Act, which provides for compensation when a public official, through intentional or negligent acts in the course of their duties, causes harm to another individual. The claim centered on the government’s failure to enact necessary legislation, which prevented the plaintiff from marrying.

The court noted same-sex relationships have existed naturally long before the establishment of legal marriage. It emphasized that recognizing such relationships as legitimate is a fundamental legal interest connected to personal dignity, transcending the confines of traditional legal frameworks governing marriage and family.

The court further observed same-sex couples encounter significant disadvantages in various aspects of social life that cannot be addressed through civil partnership systems. These include housing challenges, such as restrictions on renting properties, and financial institutions refusing to recognize same-sex couples as family members for mortgages. Same-sex couples also face hurdles in accessing products and services tailored to family relationships. While the court deemed the relevant provisions unconstitutional, it clarified that the government’s failure to enact legislative changes does not constitute a violation under the State Redress Act.

The lawsuit, titled “Freedom of Marriage for All,” brought together a large coalition of professionals, including more than 30 plaintiffs and 80 lawyers. They filed six lawsuits in five courts throughout Japan.

“We filed these lawsuits on Valentine’s Day, Feb. 14, 2019, in Tokyo, Osaka, Nagoya, and Sapporo, and in September of that year in Fukuoka,” noted Takeharu Kato, director of Marriage for All Japan. “Then, in March 2021, the Sapporo District Court handed down the first ruling declaring the current laws unconstitutional, which received extensive worldwide media coverage. Subsequently, the Osaka District Court unfortunately ruled that the current law is constitutional, but among the 10 rulings handed down so far, nine have ruled that not recognizing marriage equality is unconstitutional.”

Kato is a lawyer who is part of the legal team in the Sapporo case. He is also a board member of Marriage for All Japan, a marriage equality campaign.

“The MFAJ (Marriage for All Japan) is fully supporting the lawsuits by publicizing the current status of the trials and the rulings in our websites and social networks, setting up press conferences at the time of the rulings,” Kato told the Washington Blade. “We also make the best of the impact of the lawsuits in our campaign by holding events with the plaintiffs of the lawsuits and inviting them to the rally at Diet (the Japanese parliament) members’ building.”

Kato said the campaign has significantly shifted public opinion, with recent polls indicating more than 70 percent of Japanese people now support marriage equality — up from approximately 40 percent before Marriage for All Japan launched. He also noted 49 percent of Diet members now back marriage equality.

Japan is the only G7 country that does not legally recognize same-sex couples. Taiwan, Nepal, and Thailand have extended full marriage rights to gays and lesbians.

Expressing disappointment, Kato said many Japanese politicians continue to resist marriage equality, despite overwhelming public support. Kato added Marriage for All Japan expects the Supreme Court to rule on their lawsuits in 2016.

“We believe that the Supreme Court will also rule that the current laws are unconstitutional,” he said. “However, the Supreme Court’s ruling alone is not enough to achieve marriage equality under the Japanese legal system. We should put more and more strong pressure on the Diet to legalize marriage equality in Japan as soon as possible.”

Several municipalities and prefectures issue certificates that provide limited benefits to same-sex couples, but they fall short of equal legal recognition.

Prime Minister Fumio Kishida’s government has faced mounting pressure on the issue as public support for marriage equality has surged in recent years. Kishida has yet to push reforms within his own party; encountering fierce opposition from its traditional leadership.

His government in June 2023 passed Japan’s first law addressing sexual orientation and gender identity, aiming to “promote understanding” and prevent “unfair discrimination.” Activists, however, widely criticized the legislation on grounds it fails to provide comprehensive protections or extend marriage rights to same-sex couples.
