Same-sex marriage in Japan

Partnership certification system

Local governments issue partnership certificates to same-sex couples. As of October 2025, hundreds of municipalities and prefectures participate in this system. Shibuya in Tokyo was the first jurisdiction to start accepting applications in late 2015. The certificates help with hospital visits and housing matters. They do not create binding legal obligations for landlords or hospitals. Some cities also recognize children and in-laws under familyship systems. A network allows different jurisdictions to honor each other's registries.

Legal challenges and rulings

Courts have increasingly found the national ban on same-sex marriage unconstitutional. A Sapporo district court made the first such ruling in March 2021. It stated that denying marriage benefits violates constitutional guarantees against discrimination. Higher courts in Sapporo and Tokyo issued similar verdicts in 2024. These decisions do not legalize marriage immediately. They pressure the National Diet to pass legislation. Bills supporting same-sex marriage were introduced in 2019 and 2023.

Political and social views

Polling shows strong public support for legalization, especially among younger people. Political parties hold divided views on the issue. The Liberal Democratic Party opposes changing the law. Other major parties support legalization or are open to discussion. Constitutional Article 24 defines marriage as between opposite sexes. Legal scholars argue this text does not explicitly forbid same-sex unions. Conservative lawmakers maintain that the current wording prohibits them.

Ceremonies and overseas options

Some temples and resorts host symbolic ceremonies for same-sex couples. Kyoto and Kawagoe temples began performing these rites in recent years. Tokyo Disney Resort has offered symbolic weddings since 2012. Japanese citizens can marry abroad where same-sex marriage is legal. The Ministry of Justice issues necessary single-status certificates for these overseas unions. This change occurred in 2009 to facilitate international marriages for gay and lesbian nationals.

When and where

This practice occurs throughout Japan. Partnership systems are strongest in urban centers like Tokyo, Osaka, and Sapporo. Over ninety percent of the population lives in areas with these local registries. The legal status varies by jurisdiction rather than being uniform nationwide.

Then and now

The custom is changing through local ordinances and court rulings. More jurisdictions are joining mutual recognition networks. Public support continues to grow. The national government has yet to legalize the union. Legal battles remain active as activists push for full equality.
