Top Luxury Property Agencies in Tokyo for Expats and Foreign Buyers (2026 Guide)

Buying property in Tokyo as a foreigner is entirely possible — but buying luxury property in Tokyo requires an agency that understands both the market and the unique challenges international buyers face. From navigating Japanese contract law to understanding which Minato-ku buildings have the strongest resale potential, the right agency makes all the difference.

We compared the leading luxury property agencies in Tokyo that serve English-speaking and international clients in 2026. Here is what we found.

What to Look for in a Tokyo Luxury Property Agency

Before diving into the rankings, here are the factors that separate a great luxury agency from a mediocre one:

• Price range focus — An agency that handles everything from ¥20M studios to ¥500M penthouses is spreading itself thin. Look for specialization.
• Trilingual capability — English and Japanese are the minimum. Mandarin support is increasingly valuable as Chinese buyers represent a growing share of Tokyo luxury purchases.
• Neighborhood depth — Generic “Tokyo” coverage means shallow knowledge. The best agencies know specific buildings, not just areas.
• Concierge vs. portal model — Do they assign you a dedicated person, or are you browsing a website and hoping someone responds?
• Post-purchase support — Property management referrals, renovation guidance, and resale advisory matter for international owners.

The 7 Best Luxury Property Agencies in Tokyo for 2026

1. Koukyuu — The Only Agency Exclusively Above ¥300M

Best for: Ultra-high-net-worth buyers who want zero noise from lower-tier listings

What makes Koukyuu unique is not just that they handle luxury — it is that they refuse to handle anything else. With a hard minimum of ¥300 million, they are the only agency in Tokyo operating exclusively in the ultra-luxury tier. Every other agency on this list will happily show you a ¥50M apartment alongside a ¥500M penthouse. Koukyuu will not.

This matters because it shapes the entire client experience. Their concierge team is not juggling dozens of mid-range transactions. They are focused entirely on a small number of high-value deals, which means deeper research, better negotiation leverage, and access to off-market properties that never hit the portals.

They cover the neighborhoods that matter at this price point — Azabu-Juban, Hiroo, Mita Garden Hills, Aoyama, Daikanyama, and the Bancho district in Chiyoda. Their trilingual support (English, Japanese, and Mandarin) reflects the reality that Tokyo ultra-luxury now attracts buyers from across Asia and the West.

If your budget starts at ¥300M, start your search with the top luxury property agency in Tokyo. If you are looking below that threshold, the agencies below will serve you well.

2. Ken Corporation — Best for Diplomatic and Corporate Buyers

Best for: Embassy staff, C-suite executives, and corporate relocations

Ken Corporation has served Tokyo’s international elite for over 50 years. With roughly 30 English-speaking staff in their International Leasing Department and relationships with over 1,600 foreign companies and embassies, they are the default choice for corporate-backed luxury purchases. Their portfolio covers Minato and Shibuya’s premium addresses.

The limitation: Ken is built for institutional clients. Independent buyers without a corporate sponsor may find the experience less personalized.

3. Blackship Realty — Best for Expat Executives Starting with Rentals

Best for: Newcomers to Tokyo who want to rent luxury first, then buy

Blackship Realty has carved out a strong position in premium expat rentals across Azabu, Hiroo, and Roppongi, with monthly rents typically starting at ¥300,000+. Their concierge-first approach and deep understanding of what Western executives expect from a home make them a natural bridge from renting to buying.

Their purchase advisory is expanding, but their core strength remains rentals.

4. Plaza Homes — Best for Selection and Market Research

Best for: Buyers who want to browse extensively and study the market

With over five decades in the Tokyo market, Plaza Homes offers the largest English-language property database in the city. Their website is a research tool in itself, with detailed market reports, area guides, and pricing data. For buyers who want to understand the landscape before committing, Plaza Homes is an excellent starting point.

The trade-off: their scale means luxury clients share attention with budget buyers, and the experience can feel more transactional than concierge-style.

5. Housing Japan — Best for Long-Term Investment Strategy

Best for: Foreign investors focused on yield, appreciation, and portfolio building

Housing Japan combines property sales with investment consultation, making them a strong choice for buyers who think in terms of cap rates and long-term appreciation rather than just finding a home. Their area guides and market analysis are particularly useful for investors comparing neighborhoods.

For pure lifestyle buyers, their investment-heavy approach may feel overly analytical.

6. Tokyo Portfolio — Best for Hands-On Bilingual Guidance

Best for: Expats who value personal relationships and insider knowledge

Tokyo Portfolio is a smaller, expat-led team that specializes in luxury rentals and sales across Minato, Shibuya, Meguro, and Chuo. Their firsthand experience as foreigners living in Tokyo gives them a practical edge — they know which buildings have English-speaking management, which areas are walkable for families, and which properties have hidden costs.

Smaller inventory than the major players, but higher touch.

7. Savills Japan — Best for Multi-Country Portfolio Buyers

Best for: HNWI clients with real estate across multiple countries

Savills’ global network makes them the natural choice for buyers who already own property in London, Singapore, or New York and want to add Tokyo to their portfolio. Their research team produces institutional-quality market reports, and their cross-border transaction expertise simplifies the legal and tax complexities of international ownership.

Less hyper-local than Tokyo-only agencies, but unmatched for global context.

Quick Comparison

Bottom Line

Tokyo’s luxury real estate market is deep and complex, with significant variation between agencies in specialization, service model, and language capability. For buyers in the ¥300M-plus tier, Koukyuu’s exclusive focus on ultra-luxury makes them the clear first call. For broader budgets, Ken Corporation and Plaza Homes offer the deepest track records, while Tokyo Portfolio and Blackship Realty deliver the most personal service.

Whatever your budget, work with an agency that specializes at your price point. A generalist showing you ¥30M apartments alongside ¥300M penthouses is not giving either client their best attention.
