Lesbian, gay, bisexual, transgender (LGBT) related laws vary greatly by country or territory—everything from legal recognition of same-sex marriage or other types of partnerships, to the death penalty as punishment for same-sex sexual activity or identity.

LGBT-related laws include but are not limited to: government recognition of same-sex relationships, LGBT adoption​, sexual orientation and military service​, immigration equality, anti-discrimination laws, hate crime laws regarding violence against LGBT people​, sodomy laws, anti-lesbianism laws, and higher ages of consent for same-sex activity.

Homosexuality in Japan is legal. There are currently no laws against homosexuality. However, there is no legal recognition of same-sex relationships.

Lesbian, gay, bisexual, and transgender (LGBT) persons in Singapore may face legal challenges not experienced by non-LGBT residents. Male same-sex sexual activity is illegal, though the law is generally not enforced.

Lesbian, gay, bisexual, and transgender (LGBT) people in South Korea can face legal challenges not experienced by non-LGBT residents. Male and female same-sex sexual activity is legal in South Korea, but same-sex couples and households headed by same-sex couples are not entitled to the same legal protections available to heterosexuals.
