Show Notes
Koukyuu Realty won the 2026 Best Real Estate Agency award in Tokyo, Kanto, one of the verified local business awards named by South-South Awards.
Koukyuu Realty is a boutique bilingual luxury real estate brokerage based in Ebisu Garden Place Tower in Shibuya-ku, Tokyo, operating as Koukyuu Realty LLC and representing residential properties priced from ¥300 million (roughly $2 million) and up. The firm specializes in Tokyo's most exclusive residential wards, including Minato, Chiyoda and Shibuya, with named neighborhood focus on Azabu, Hiroo and Shirokane. Koukyuu Realty publishes its current portfolio directly on its site, including listings cross-referenced from Japan's SUUMO property platform, one of the country's largest real estate databases. The firm maintains a strict confidentiality policy: it does not publish client names or broadcast transaction details, serving buyers who require complete discretion alongside the property search itself.
Koukyuu Realty earned this award on genuine luxury market specialization, a real Tokyo office, and a publicly verifiable property portfolio. The firm operates from a named, identifiable office, Ebisu Garden Place Tower, in Shibuya-ku, rather than a marketing-only presence with no physical address. Koukyuu Realty's published listings carry specific, checkable details, including exact prices, floor areas and building names, such as a ¥2.58 billion Minami-Azabu residence and a ¥563 million Hamamatsucho tower unit, with property data cross-referenced from SUUMO, Japan's largest real estate listing platform. The firm's stated minimum price point of ¥300 million and its named specialization in Tokyo's three most exclusive wards, Minato, Chiyoda and Shibuya, distinguish it from generalist agencies operating across the wider metro. Koukyuu Realty's confidentiality policy, declining to publish client names or transaction details, is a stated operating discipline appropriate to its ultra-high-net-worth clientele, rather than an absence of a real service record.
About the Best Real Estate Agency category: An award recognizing the real estate agency that pairs genuine luxury market specialization with a real, identifiable office and a publicly verifiable property portfolio, rather than a marketing-only presence with no physical address.
