Debate has occurred throughout Asia over proposals to legalize same-sex marriage as well as civil unions.
Following a Constitutional Court ruling and a subsequent legislative act, Taiwan became the first country in Asia to legalize same-sex marriage nationwide on 24 May 2019, followed by Thailand on 23 January 2025.
In addition, Israel recognises same-sex marriages performed abroad, though not as full marriage, and same-sex marriages are legal in the UK sovereign base areas of Akrotiri and Dhekelia and the British Indian Ocean Territory.
Israel also recognises unregistered cohabitation for same-sex couples. Some cities in Cambodia provide same-sex couples with some limited rights and benefits, including hospital visitation rights. Several prefectures in Japan issue partnership certificates for same-sex couples. In Hong Kong, the same-sex partners of residents can receive spousal visas and spousal benefits.
In 2019, a survey by The Economist found that 45% of respondents in the Asia-Pacific region believed same-sex marriage is inevitable in the region, with 31% of respondents disagreeing. Also, three-quarters of those surveyed reported a more open climate for LGBT rights compared to three years ago. Of those reporting an improving climate for LGBT people, 38% cited a change in policies or laws, while 36% said coverage of LGBT issues in mainstream media was a major factor. The top reason cited for diminishing openness was anti-LGBT advocacy by religious institutions.
