A closed space with a few hundred members. The intake screening asks the man for proof of income, proof of occupation, and a guarantor, and the annual fee alone runs to several hundred thousand yen. A concierge shows photo profiles; if he likes one, he pays an introduction fee and meets her for the first time. The venue is limited to a private room in a members’ club or a luxury hotel lounge. This is a membership business that puts out no signboard.

Kousai club is a membership introduction business that, to male members who pass a screening and pay fees, introduces registered women one-to-one. Also called a dating club or high-end introduction club, it is positioned as an affluent-clientele market above papa-katsu apps. It settled from the 2000s, centred on Azabu, Ginza, and Akasaka in Tokyo and the Kita-Shinchi area of Osaka. This entry describes the model and its legal position in neutral terms; it does not endorse or facilitate the arrangement, and notes that where a minor is involved the activity becomes child prostitution and is criminal.

How it works

A man pays an entry fee of 50,000 to 300,000 yen and an annual fee of roughly 100,000 to 500,000 yen to register. He is asked for proof of occupation, income, and address; upper-tier clubs limit membership to attributes such as company executive, physician, lawyer, or listed-company director. A woman registers free of charge after an appearance screening and interview. The deliberate asymmetry between the two registration pools is what secures the business’s added value.

Introductions go through the venue’s concierge. The man views a woman’s profile and, if he wishes to proceed, pays an introduction fee of 10,000 to 30,000 yen. A first meeting runs about an hour in a designated lounge; if both wish to continue, they exchange contacts and subsequent meetings are left to the parties. By custom the man passes money directly to the woman without the venue’s involvement.

Relation to the sex-industry laws

A kousai club presents itself as a “members’ social venue” and provides no sexual service on its premises. Legally it is not a sex-industry business; some venues operate under the “marriage-partner introduction business” frame, the same as a marriage agency. In practice, however, a premise that the parties may agree to a sexual relationship is common tacit knowledge in the trade, so the business functions in effect as an affluent-clientele introduction service.

Under the Anti-Prostitution Law, a venue that brokers sexual consideration is illegal; the venue therefore maintains rigorously that it “only arranges meetings” and that any sexual relationship is “a private matter between individuals.” This construction is the trade knowledge by which the grey zone is kept open, and staff will change the subject at once if sexual service is mentioned in conversation. Where any party is under 18, the construction collapses entirely: the conduct falls under child-prostitution law and is a serious crime regardless of the parties’ framing.

History

Postwar affluent-clientele introduction businesses lay on a line extending from ryotei and geisha culture. The non-public “after” introductions run by Ginza and Akasaka clubs during the 1980s bubble were the direct precursor. From the late 1990s, businesses began to become independent under the guise of a “marriage introduction office.” In the 2000s, large chains appeared and the form became recognised. The spread of papa-katsu apps in the 2010s drew off part of the clientele, but a demand among the affluent for vetted identities and avoidance of trouble with amateur women kept the kousai club alive as an upper-tier market.

Difference from papa-katsu apps

Where papa-katsu apps compete on anonymity and match volume, kousai clubs sell vetted trust through prior screening, trouble avoidance through concierge brokering, and introduction quality through the venue’s network. Fees also run higher than the papa-katsu range. A woman’s motive for registering is contact with high-income strata she cannot reach through apps, while the venue’s pressure to maintain conduct demands a degree of manner and education from her in turn.
