Marriage Equality in Japan: Progress, Challenges, and the Road Ahead

Understanding the Legal Status of Same-Sex Marriage in Japan

Japan stands at a legal crossroads when it comes to same sex marriage. As of 2025, same-sex marriage is still not legally recognized in Japan, leaving same-sex couples without the full protections and rights afforded by marriage. However, the country has made a significant step toward greater equality with more than 300 municipalities now issuing partnership certificates, providing some local recognition of same sex relationships. Since 2024, Japan's judicial landscape has seen remarkable progress, with five high district courts declaring the ban on same-sex marriage is unconstitutional. While the road to legal reform remains uncertain, these judicial milestones have brought the issue to the forefront of national conversation and placed increasing pressure on lawmakers to act.

Recent Court Rulings: A Shift Towards Equality

In a groundbreaking wave of judicial rulings throughout 2024 and 2025, several high courts in Japan ruled that Japan's ban on same-sex marriage is unconstitutional, citing violations of equality under the law. These decisions mark a turning point in Japan's ongoing legal battle for marriage equality, with courts acknowledging that the nation's ban on same-sex marriage unjustly discriminates against the LGBTQ Community. The Sapporo District Court led the way with a historic verdict in March 2024, ruling that Japan's civil code provisions excluding same-sex couples from marriage violate constitutional principles of equality. This was followed by the Tokyo District Court in October 2024, which reinforced this perspective and added momentum to the nationwide push for marriage equality.

In March 2025, the Nagoya District Court joined others in declaring Japan's same-sex marriage ban unconstitutional. Notably, the Osaka District Court, which had once upheld the ban, reversed its stance, becoming the fifth high court to rule against it, underscoring a major shift in judicial perspective. These rulings, while not striking down the law, declare a "state of unconstitutionality," recognizing that denying marriage rights to same-sex couples violates principles of equality and individual dignity. With momentum building, attention now turns to the Japanese Supreme Court, whose future ruling could be the turning point in legalising same-sex marriage and ending Japan’s fragmented approach to LGBTQ+ recognition.

Public Opinion and Political Landscape

Public support for same-sex marriage in Japan has grown significantly in recent years, reflecting a major shift in public attitudes. A 2023 Asahi Shimbun survey found that 72% of respondents now support legalization, up from 41% in 2015, while opposition has fallen from 37% to 18%. This shift is especially strong among younger people, with a clear majority under 30 expressing strong support for marriage equality. As same-sex couples become more visible and advocacy efforts raise awareness, more Japanese view the current legal stance as outdated and unjust. The belief that the ban violates principles of equality and personal freedom is gaining ground, increasing pressure on lawmakers to respond to changing public values.

Despite this widespread public support, political resistance remains a major hurdle. The ruling Liberal Democratic Party (LDP) continues to oppose legalizing same-sex marriage, often citing traditional values and concerns about societal impact. Some members argue that same sex marriage violates Japan’s constitutional definition of marriage as between a man and a woman, blocking meaningful legislative progress even as courts rule that the ban violates constitutional equality guarantees. While a few LDP members have expressed more progressive views, the party leadership insists the issue requires careful national debate, delaying substantial action. This gap between public opinion and the policies of the Japanese government remains a major obstacle in the fight for marriage equality.

Role of Advocacy Groups: Marriage for All Japan

Advocacy groups in Japan have played a leading role in the fight for marriage equality, promoting human rights and amplifying the voices of the LGBTQ community. Organizations like Marriage for All Japan have been key drivers of progress, backing constitutional court cases, offering legal support to same-sex couples, and running nationwide campaigns to highlight the importance of equal marriage rights. Groups such as the Japan Alliance for LGBT Legislation (J-ALL) and Lawyers for LGBT & Allies Network (LLAN) also work to advance legal protections and push for legislative change. Together, these LGBTQ groups and their corporate partners are reshaping public discourse, challenging discriminatory norms, and building a broader coalition pushing for lasting legislative change in Japan.

Alternative Ceremonies and Cultural Acceptance

In Japan, many same-sex couples are finding meaningful ways to celebrate their unions through symbolic ceremonies, blending tradition with modern identity despite the lack of legal recognition. More religious institutions and wedding venues are now welcoming same-sex couples, offering personalized ceremonies to honor their love. For instance, Saimyoji Temple in Kawagoe, Saitama Prefecture, began hosting same-sex weddings in May 2023, where couples receive Buddhist rosaries instead of rings and exchange vows before a Buddhist altar, often with professional photo shoots to mark the day. Similarly, Negainomiya Shrine in Osaka’s Chuo Ward now offers Shinto-style wedding rites to same-sex couples, reflecting growing acceptance in religious circles. These ceremonies align with a broader movement that began in 2015, when Shibuya and Setagaya wards in Tokyo introduced same-sex partnership certificates. Today, over 300 municipalities issue such certificates, providing symbolic but meaningful recognition and helping pave the way toward wider societal acceptance.

International Context: Japan Among G7 Nations

Japan remains the only G7 nation that has not legalized same-sex marriage, highlighting a significant gap in legal protections for its LGBTQ+ community compared to its global counterparts. While countries like Canada, the U.S., Germany, and the U.K. have long embraced marriage equality, Japan’s continued ban places it increasingly at odds with international progress on human rights and inclusion. Without legal recognition, same-sex couples are denied equal rights and protections, and the broader message is clear: LGBTQ+ individuals in Japan still lack full legal equality. As domestic support for marriage equality grows, Japan's divergence from other G7 nations underscores the pressing need for legal reform to uphold the rights and dignity of all citizens.

Challenges Faced by Same-Sex Couples

Same-sex couples in Japan continue to face serious challenges due to the lack of a comprehensive legal framework to recognize same-sex marriage. Without the same rights and protections afforded to heterosexual couples, they often struggle with critical issues such as inheritance, hospital visitation, and parental rights. Under the Family Register Act, which only applies to heterosexual marriages, same-sex partners cannot be listed as spouses or legal parents, excluding them from key legal and social benefits.For instance, if one partner becomes seriously ill, the other may be denied visitation or the ability to make medical decisions, as they are not recognized as legal family members.

Inheritance disputes are also a frequent concern, as same-sex partners in Japan have no automatic right to inherit their partner’s assets without a will, often putting surviving partners in difficult legal and financial positions. Additionally, many sexual minorities are calling not only for greater awareness and acceptance of diverse sexual orientations, but for clear anti-discrimination laws that explicitly protect LGBTQ+ individuals. These persistent legal gaps affect the everyday lives of LGBTQ+ people, underscoring the pressing need for meaningful reform and equality.

Corporate and Municipal Support

Support for LGBTQ+ rights from both corporations and local governments in Japan has been steadily increasing. Companies like Yamaha Corporation have taken a proactive stance, introducing inclusive policies such as recognizing same-sex partners as family members, which allows employees to access benefits like parental and nursing care leave regardless of gender. In 2022, Yamaha also joined the Business for Marriage Equality (BME) campaign, which highlights companies advocating for marriage equality and encourages broader corporate support. At the municipal level, over 300 local governments now issue partnership certificates to same-sex couples. While not legally binding, these certificates offer limited legal benefits, such as hospital visitation rights and eligibility for public housing. Combined, these corporate and municipal initiatives are helping to foster greater inclusivity and close the gap left by the absence of national legal recognition for same-sex marriage.

Future Outlook: Steps Toward Legalization

The future of same-sex marriage in Japan appears promising, thanks to years of advocacy, shifting public attitudes, and supportive court rulings that have gradually brought the country closer to equality. Since the fight for marriage equality began, Japan has seen over 300 municipalities introduce same-sex partnership certificates, increased corporate and municipal support, and landmark court decisions declaring the ban on same-sex marriage unconstitutional. Public opinion has also shifted significantly, with more than 70% of Japanese citizens now in favor of legalization. Despite these advances, political challenges remain, particularly from the ruling Liberal Democratic Party. However, the growing momentum from grassroots activism, corporate backing, and legal progress indicates that change is on the horizon. While the journey may be slow, each milestone brings Japan closer to fully recognizing same-sex marriage under the law.

Conclusion: The Path to Equality Continues

While progress has been made, the journey toward full marriage equality in Japan is far from over. It is the unwavering resilience and determination of the LGBTQ+ community and its allies that continue to fuel the push for change, challenging long-standing traditions and political resistance. With increasing public support and continued legal victories, the path toward equal rights may be slow, but it is undeniably moving forward, bringing hope for a future where love is recognized and celebrated for all.
