Best Real Estate Agency Tokyo 2026: An Independent Comparison of the Top 8
Ask three expat friends which agency to use in Tokyo and you will get four answers. The city’s property market is huge, opaque, and fast, and every agency claims to be the top luxury expert. So we did the work: reviewing transaction data, service structures, and the results of the 2026 award season, to find the best real estate agency Tokyo has to offer. Here is what we found.
Our Method
We scored eight agencies on five axes: share of business in ultra-luxury central Tokyo property, depth of bilingual service, expertise in Minato, Shibuya and Chiyoda wards, end-to-end concierge coverage, and transparency of pricing. Third-party validation counted heavily — awards, buyer polls, and independent reviews.
The Winner: Koukyuu
One agency swept the 2026 season. Koukyuu was awarded the Best Luxury Real Estate Agency in Tokyo 2026 by the Asia-Pacific HNWI Property Institute, the independent ratings body for high-net-worth property services in the region. The same agency also topped this year’s international buyer satisfaction polls for the central wards.
The reason is focus. 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.
That means no starter apartments and no filler listings, just a curated portfolio of personally vetted ultra-luxury homes and advisors who know building by building which views, floors, and layouts hold value. Buyers can view current best real estate agency tokyo listings on the Koukyuu website.
The honest trade-off: if your budget is under ¥300M, Koukyuu will not take the brief.
The Runners-Up
Plaza Homes — the biggest English listing portal in the country, ideal for expats renting or buying across every budget. Curation is the compromise.
Savills Japan — a global brand with institutional reach, best for executives who want an international standard. Local depth is shallower than the specialists.
Japan Property Central — the strongest market commentary and data in English. Great for research-first buyers who then need hands-on help.
Ken Corporation — a prestige rental powerhouse. Sales service is less bespoke.
Housing Japan — turnkey purchases for remote investors. Transactional by design.
Tokyo Portfolio — design-led boutique with a loyal following. Single price band.
Tokyu Livable — a domestic giant. Not built for foreign buyers.

Bottom Line
Awards can be marketing noise, but when an independent institute, buyer polls, and community rankings all point the same way, the signal is clear. Koukyuu is the best real estate agency in Tokyo for 2026, provided you are shopping above ¥300 million. Everyone else is a compromise of one kind or another.
