A narrow alley in Shinjuku Ni-chōme, late at night. The bars open onto the street through small frontages, regulars and visitors leaning at the same counter. The neighbourhood is the geographic anchor of the postwar Japanese gay community. The vocabulary that men in the bars use to name themselves has shifted several times across the twentieth century: from the pre-modern wakashū of the Edo theatre district, to the early-twentieth-century medical category hentai-seiyoku (“perverse sexual desire”), to the postwar homo, to the contemporary gei. Each shift carries the history of a particular legal, medical, and movement-political moment.

Gay (Japanese: ゲイ, gei; older English variants: homosexual male; older Japanese: ホモ, homo, now widely treated as carrying derogatory weight) is the sexual-orientation category for men whose sexual or romantic attraction is toward men. The category is the male counterpart of lesbian within the LGBTQ+ orientation-vocabulary and is one of the foundational identity-categories of contemporary international queer politics.

This entry concentrates on the Japanese context: the pre-modern background, the post-war emergence of the gay community, the vocabulary shift from homo to gei, the Shinjuku Ni-chōme neighbourhood as community anchor, and the partial development of same-sex partnership recognition.

Vocabulary

English-language gay is the standard self-identification and clinical term. The shorter form gay (lowercase, adjective and noun) is the unmarked usage; homosexual survives in some clinical contexts but carries colder, more medicalised register and is generally avoided in community self-identification. MSM (men who have sex with men) operates in epidemiological and public-health writing as a behaviour-focused term that does not presuppose identity.

Japanese-language gei (ゲイ) is the contemporary standard term, in clinical, journalistic, and community-self-identification registers. The older homo (ホモ) retains residual currency in casual speech but is widely treated as carrying derogatory weight in community-aware contexts, and serious journalism and clinical writing have substantially shifted to gei since the 1990s. Dansei dōseiaisha (男性同性愛者, “male same-sex-attraction person”) is the more formal clinical-legal compound.

The Japanese-context vocabulary also retains the term nonke (ノンケ, originally a sex-trade-and-gay-bar register term for “non-business” or “straight”; “non-” + ke, where ke is a vague suffix meaning “type” or “sort”), used within the gay community to refer to heterosexual men.

Etymology

English gay derives from Old French gai (“merry, lively”) via Middle English, where it carried the meaning “cheerful, brightly coloured, flamboyant” through the medieval and early-modern periods. The slang extension to “sexually licentious” emerged in nineteenth-century English, and the further specialisation to “male homosexual” (initially as in-group self-identification) stabilised within American gay communities through the early-to-mid twentieth century. The 1969 Stonewall riots and the subsequent Gay Liberation Front, Gay Pride, and Gay Activists Alliance organisations drove the public adoption of gay as the standard self-identification term across the Anglophone world.

The Japanese adoption of gei came through the 1970s-1990s influx of English-language gay culture (films, music, publications) and stabilised as the preferred self-identification term in the 1990s in parallel with the broader community-organisation development.

Pre-modern Japan

Pre-modern Japan offers an unusually well-documented record of male-male sexuality, substantially better-documented than the corresponding record for female-female sexuality. References to male-male sexual or romantic relationships appear in early texts (Kojiki, Nihon Shoki); the Heian-period aristocratic and Buddhist-clerical contexts produced extensive male-male relational vocabulary, with Fujiwara no Yorinaga’s Taiki (12th century) providing a candidly-recorded diary of aristocratic male-male relationships.

From the medieval period onward, a distinct institutional form of male-male relationship developed within warrior society and Buddhist monasticism: shudō (衆道) or wakashūdō (若衆道, “the way of youths”), a stylised relationship between an adult man and an adolescent male partner, intersecting with master-apprentice and lord-retainer relationships. Ihara Saikaku’s The Great Mirror of Male Love (Nanshoku Ōkagami, 1687) provides a systematic literary record of the practice across both warrior and townsman societies in the Edo period.

The Edo-period commercial sex industry included a substantial male-male sector centred on the kagema, young male kabuki actors who provided sexual services to a clientele of samurai, townsmen, and Buddhist clerics. Kagema-jaya (male-prostitution teahouses) operated in the Yoshichō, Yushima, and Shiba districts of Edo, the Miyagawachō district of Kyoto, and similar locations, forming a recognised commercial-sex sub-sector that paralleled the female prostitution industry.

Meiji period: medicalisation

The Meiji-period Western-knowledge influx reframed male-male sexuality through the lens of Western sexology. Translations of Krafft-Ebing’s Psychopathia Sexualis (1913 in Japanese) and Havelock Ellis’s Studies in the Psychology of Sex established the diagnostic-medical framing of male-male attraction as hentai-seiyoku (variant or perverse sexual desire), competing with the persistence of cultural-historical readings that placed the same phenomenon within the shudō literary tradition.

Pre-modern shudō and wakashūdō practice declined rapidly under modernisation pressure. The 1873 Keikan-ritsu-jōrei (Sodomy Prohibition Edict) briefly criminalised male-male anal intercourse, but the 1880 Old Penal Code repealed this provision, and Japanese criminal law from 1880 onward did not criminalise same-sex sexual activity per se — a substantially different trajectory from the criminalisation regimes of contemporary Anglophone jurisdictions.

Post-war community formation

The post-war urban landscape — Shinjuku, Ueno, Asakusa — saw the underground formation of male-male meeting places. The 1950s and 1960s saw the emergence of gay-targeted magazines: Fūzoku-Kitan (1960s), Barazoku (薔薇族, 1971-2008, founded by Itō Bungaku), Sabu (1974-2002), and Adon (1974-onward). These publications combined reader contributions, literature, photography, and personal accounts, and operated as the principal infrastructure of postwar Japanese gay community formation.

Throughout this period and well into the 1990s, mainstream Japanese-language reference to the community used the loanword homo. The term came to be widely recognised within the community as carrying derogatory weight, and the gradual vocabulary shift to gei through the 1990s reflected the broader community-organisation maturation.

Stonewall, Pride, and the international movement

The international context for Japanese gay-community development is the post-Stonewall (1969 New York City) emergence of the Gay Liberation Front, the development of annual Pride events, and the AIDS-crisis-driven community-organisation acceleration of the 1980s. Japanese gay-community organising drew on this international context, with mid-1980s organisation-formation (Akā / OCCUR, founded 1986) and 1990s parade events (the first Tokyo Lesbian and Gay Parade in 1994, predecessor to the contemporary annual Tokyo Rainbow Pride held each April) reflecting the international template adapted to Japanese conditions.

The 1990s saw the Fuchū Youth Centre case (1990, in which the Tokyo Metropolitan Board of Education denied the gay-rights group OCCUR’s overnight-stay application; the courts eventually ruled for the plaintiffs), the first major Japanese-court ruling that established gay-community-organisation use of public facilities as a protected interest.

HIV/AIDS

The 1980s-1990s HIV/AIDS crisis affected the Japanese gay community as it did communities elsewhere, but the Japanese policy response was substantially distorted by the parallel scandal of HIV-contaminated blood-product distribution to haemophilia patients (“yakugai-AIDS”), which absorbed most public-policy and media attention. Community-based and support-organisation work (Place Tokyo, the Living Together project, others) developed in parallel and continues to provide HIV testing, prevention education, and patient support.

2000s onward: institutional development

From the late 2000s, the Japanese gay community’s social visibility expanded substantially. Tokyo Rainbow Pride (annual April event) became a major public visibility moment; Japanese commercial and broadcast media expanded their representation of gay individuals; LGBTQ+ characters became increasingly normalised in manga, anime, and television.

In November 2015, Shibuya Ward (Tokyo) implemented the country’s first municipal-level same-sex partnership ordinance, and Setagaya Ward followed shortly with an administrative-procedure version. The municipal partnership-system expansion thereafter has been rapid: 328 municipalities by June 2023, 459 by June 2024, and over 90% population-coverage by May 2025 according to Shibuya Ward joint surveys. These municipal systems do not carry the legal effect of marriage; constitutional litigation across multiple high-court jurisdictions (Sapporo, Tokyo, Osaka, Fukuoka, Nagoya) has produced unconstitutional or constitutionally-suspect rulings, but national-legislative same-sex marriage remains unimplemented as of 2026.

In June 2023, the Act on Promotion of Public Understanding of Diverse Sexual Orientation and Gender Identity (LGBT Understanding Promotion Act) was enacted. The Act is a principles-level statute without penal provisions and has been described by advocacy organisations as inadequate, but it represents the first national-level Japanese legislation on LGBTQ+ themes.

Shinjuku Ni-chōme

Shinjuku Ni-chōme (新宿二丁目), a small district in central Tokyo, has functioned as the geographic anchor of the postwar Japanese gay community. The district evolved through the 1950s-1960s from a gaishō (street-prostitution) area into a clustered gay-bar district, and by the 1980s had achieved international recognition as Tokyo’s gay neighbourhood.

At its 1990s-2000s peak, the district housed approximately 300 gay bars, mixed bars, lesbian bars, clubs, saunas, and gay-targeted bookshops in an area of a few city blocks. Individual establishments often have specific client-type identities (age range, type, occupation), supporting a layered intra-community sociality. Fushimi Noriaki’s Shinjuku Nichōme: A Sociology of “Our Town” (2004) is among the foundational sociological accounts of the district.

Regional gay communities in Osaka (Dōyama-chō), Nagoya (Ikeda-chō), Fukuoka (Haruyoshi), Kyoto (Kiyamachi), and elsewhere maintain locally-scaled versions of the clustered-establishment model.

Comparison with Anglophone trajectories

The Anglophone gay-rights trajectory — Stonewall 1969 → Gay Liberation Front 1969-onward → AIDS crisis 1980s-90s → marriage equality (Netherlands 2001 onward, USA 2015 Obergefell, 30+ jurisdictions by 2026) — represents the standard Western comparison case. Japan’s failure to legislate national same-sex marriage places it among the laggards within OECD jurisdictions on this dimension.

Within Asia, Taiwan’s 2019 same-sex marriage legislation and Thailand’s 2024 legislation have outpaced Japan. China, South Korea, and Singapore have all decriminalised same-sex sexual conduct but have not legislated same-sex marriage.
