2026 Award
Best Real Estate Agency in Tokyo
Koukyuu Realty won the 2026 Best Real Estate Agency award from South-South Awards.
Koukyuu Realty operates in Tokyo, Kanto.
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.
Why this business was selected
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.
