What Zwei does

Zwei (ツヴァイ), TSE ticker tyo:2417, is one of Japan's largest dedicated marriage matchmaking agencies (結婚相談所), founded in 1984 and headquartered in Ginza, Tokyo. The company operates 54 physical stores nationwide and serves individual consumers seeking marriage partners, with 14,564 new members registered in 2025. Its core product is a hybrid matchmaking service combining 9 distinct introduction methods — including profile-based search, AI-assisted matching, and counselor-led introductions — supported by JLCA-certified marriage counselors who perform in-person interviews and ongoing coaching.

The underlying technology stack combines a proprietary member profile database with identity-verified single-member status (all members must submit documentation confirming they are unmarried). Zwei members gain access to the broader IBJ federation network of 87,901 members across approximately 4,000 affiliated agencies, creating a combined pool of 112,000+ verified singles. The platform processed 196,489 omiai dates in 2025 and generated 3,628 marriages, of which 2,835 came through IBJ federation matches — making Zwei the No. 1 marriage contributor within the IBJ network.

Zwei's business model operates on a three-part fee structure: an initial enrollment fee of ¥118,800–¥129,800, a monthly subscription of ¥15,950–¥18,700, and a success fee ranging from ¥0 (Introduction Plan) to ¥220,000 (IBJ Plan, paid on IBJ-network marriages). A supplementary corporate membership channel allows employers to subsidize employee matchmaking fees. Zwei is a consolidated subsidiary of IBJ, Inc., listed on the Tokyo Stock Exchange Prime Market, with 251–500 employees.
