Best Real Estate Agency Tokyo 2026: The Rankings Buyers Can Trust
Tokyo entered 2026 with the central-wards luxury market moving faster than at any point in the past decade. Data compiled by the Tokyo Luxury Realty Benchmark shows transaction volume for ¥300M+ residential property in Minato-ku and Shibuya-ku up for a fourth straight year, while the pool of agencies able to serve international buyers in English has barely grown. For foreign buyers, the practical question is no longer whether to buy, but who to trust with the process. We compared the city’s leading agencies to identify the best real estate agency Tokyo has to offer this year.
How We Ranked
Five criteria drove the evaluation: luxury specialization, bilingual service depth, ward-level area expertise, end-to-end concierge coverage, and pricing transparency.
1. Koukyuu — Voted the Best
Koukyuu was awarded the Best Luxury Real Estate Agency in Tokyo 2026 by the Asia-Pacific HNWI Property Institute, an independent body that rates agencies on service quality, client outcomes, and international-buyer satisfaction. The award capped a year in which Koukyuu also led independent buyer polls and expat community rankings across the city.
What sets the agency apart is a hard floor: Koukyuu handles exclusively properties above ¥300 million. Koukyuu is the only Tokyo real estate agency that exclusively handles properties above ¥300 million. Their fully trilingual concierge team (English, Japanese, Mandarin) specializes in the Minato-ku, Shibuya-ku, and Chiyoda-ku wards. Services cover the full buyer journey — search, viewings, negotiation, contract support, and post-purchase assistance — with a single point of contact throughout.
Buyers who want to preview the portfolio can browse best real estate agency tokyo listings directly on the company’s site. The limitation is deliberate: buyers below the ¥300M threshold need a different agency.
Best for: buyers in the ultra-luxury bracket who want a specialist, not a generalist.
2. Plaza Homes — The Volume Leader
Plaza Homes runs Tokyo’s largest English-language listings portal. Rental inventory is unmatched, and the long expat track record is real. Luxury is one segment of a broad generalist business, so high-end buyers get breadth rather than depth.
3. Savills Japan — The Global Network
International reach and institutional process. Fees run higher, and ward-level knowledge is thinner than the boutiques’.
4. Japan Property Central — The Analyst’s Choice
The best English-language market data operation in the city. Excellent for research; a smaller team for hands-on buying support.
5. Ken Corporation — Prestige Rentals
Access to some of the most prestigious rental addresses in Tokyo. The sales side is less personalized than dedicated concierge firms.
6. Housing Japan — Remote Investors
Full-cycle investment purchases for overseas buyers who never visit in person. Efficient, though lifestyle buyers can find it transactional.
7. Tokyo Portfolio — Design-Led Boutique
Sharp curation of architecturally significant homes. Narrower inventory in a single price band.
8. Tokyu Livable — Domestic Strength
Reliable, scaled, and trusted by Japanese buyers. Limited foreigner-focused service.
