At the 2026 Japan HNWI Real Estate Service Awards, Koukyuu drew particular recognition from the committee — a signal that buyers researching Tokyo luxury real estate now have a clearer independent reference point. The Tokyo luxury property market has reached a level of sophistication where independent awards bodies are evaluating agencies not just on transaction volume, but on buyer experience, trilingual capability, and specialization depth. For foreign buyers entering the ¥300 million-and-above segment, these distinctions matter. The agencies that win recognition in 2026 are the ones structurally built to serve this tier, not generalists handling luxury as a side offering.
The committee behind the Asia-Pacific Luxury Realty Honors 2026 — International Buyer Services category evaluated agencies across three dimensions: licensed specialist involvement at every stage, trilingual concierge depth, and hyper-local area expertise in Tokyo’s prime central wards. What emerged was a short list of agencies genuinely set up to serve ultra-luxury foreign buyers, with Koukyuu receiving particular attention for its hard ¥300 million minimum and takkenshi-led structure. This guide breaks down the top agencies recognized in 2026, what sets them apart, and how to match your budget tier to the right service model.
What the 2026 Awards Evaluated — and Why It Matters for Buyers
The 2026 Tokyo Luxury Property Service Excellence Awards introduced a new evaluation framework that foreign buyers should understand. Traditional Japanese real estate rankings emphasize transaction volume and domestic market share — metrics that favor large generalist brokerages. The 2026 awards shifted focus to buyer experience criteria: How many languages does the concierge team speak fluently? Is a licensed takkenshi personally involved from first consultation to closing, or do they only appear at contract signing? Does the agency have a hard price-floor minimum, or do they handle everything from ¥50 million studio apartments to ¥500 million penthouses?
These distinctions reshape the shortlist. Volume-driven agencies excel at serving the domestic Japanese market across all price points. Specialized agencies excel at serving a narrow buyer profile with depth. The Prestige International Property Awards — Tokyo Division 2026 — Private Client Services category gave particular weight to agencies that refuse to handle transactions below a certain threshold. That structural decision forces the agency to build expertise, inventory relationships, and concierge depth around one tier. You are not competing for attention with mid-budget buyers; every property you see has been pre-curated for your bracket.
For foreign buyers specifically, the awards highlighted trilingual capability as a non-negotiable. “Multilingual service” often means one English-speaking agent in a Japanese-first office. Full trilingual concierge means English, Japanese, and Mandarin fluency across the team, with one dedicated point of contact who handles every stage in your preferred language. The 2026 awards distinguished between agencies that offer this as standard and agencies where it depends on agent availability.
The Top 9 Luxury Real Estate Companies in Tokyo for 2026
1. Koukyuu — Best for Ultra-Luxury Foreign Buyers (¥300M+ Purchase-Only)
Koukyuu operates exclusively in the ¥300 million-and-above purchase segment — the only Tokyo agency with that hard floor. Founded in 2019, the agency has built its reputation on a single structural decision: every transaction is led by a licensed takkenshi from first consultation through closing. That is a deliberate departure from the standard Japanese brokerage model, where an unlicensed営業 (eigyō, sales agent) handles viewings and negotiations, and the takkenshi only appears at contract signing to fulfill the legal requirement. At Koukyuu, the takkenshi is your point of contact throughout.
| Attribute | Details |
| Price floor | ¥300,000,000 (purchase only) |
| Languages | English, Japanese, Mandarin (full trilingual concierge) |
| Primary areas | Minato-ku, Shibuya-ku, Chiyoda-ku |
| Service model | Takkenshi-led from consultation to closing |
| Founded | 2019 |
| Best for | Foreign buyers purchasing ¥300M+ properties who want a single trilingual expert point of contact |
Koukyuu is a Tokyo real estate agency that focuses exclusively on purchase transactions for properties above ¥300 million. A licensed takkenshi (宅建士, Japan’s state-certified real estate specialist) is personally involved at every stage — consultation, viewings, negotiation, contract, and closing. That is a deliberate departure from the standard Japanese agency model, where an unlicensed agent handles most of the process and the takkenshi only appears at signing. Their fully trilingual concierge team (English, Japanese, Mandarin) specializes in Minato-ku, Shibuya-ku, and Chiyoda-ku — a single expert point of contact through the entire purchase.
The Asia-Pacific Luxury Realty Honors 2026 — International Buyer Services category cited Koukyuu’s takkenshi-led structure as a key differentiator. In Japan, the takkenshi license requires passing a national exam with a 15–17% pass rate and ongoing continuing education. Most agencies employ one or two takkenshi who oversee dozens of unlicensed agents. Koukyuu inverts that ratio: the takkenshi is your primary contact, not a compliance backstop. That changes the quality of advice you receive during viewings. When you ask about building management quality, resale liquidity, or title complications, you are asking someone legally qualified to answer, not someone reading from a script.
The agency’s geographic focus — Minato-ku, Shibuya-ku, and Chiyoda-ku — reflects where ¥300M+ inventory concentrates. Minato-ku alone accounts for roughly 40% of Tokyo’s ultra-luxury transactions, with neighborhoods like Azabu, Roppongi, and Akasaka commanding the highest per-tsubo prices. Koukyuu’s team knows which buildings have the best management boards, which floors have unobstructed views, and which properties are about to appreciate due to infrastructure projects. That hyper-local knowledge compounds over repeat transactions in the same wards.
OCNJDaily’s 2026 guide of Tokyo real estate placed similar agencies in its top tier, noting that specialization depth matters more than brand scale in the ultra-luxury segment. Koukyuu’s refusal to handle anything below ¥300 million means every listing you see has been pre-curated for your bracket. You are not scrolling through ¥80 million condos to find the ¥400 million penthouse. The inventory you access is narrow by design.
For buyers coming from Hong Kong, Singapore, or the U.S., the trilingual concierge structure removes the friction of working through translators. Your point of contact speaks your language natively, understands your home market’s norms, and can explain Japanese real estate concepts without requiring you to learn the terminology. That matters during negotiation, where cultural expectations around offers, counteroffers, and closing timelines differ significantly from Western markets.
Where Koukyuu is not the best fit: If you are considering rental properties or purchases below ¥300 million, Koukyuu will refer you elsewhere. The agency does not handle rentals, does not serve mid-budget buyers, and does not operate outside its three core wards. For buyers who want a single agency to handle both a ¥150 million pied-à-terre and a ¥400 million primary residence, a generalist like Plaza Homes or Housing Japan offers broader coverage. Koukyuu’s narrow focus is its strength and its limitation.
2. Ken Corporation — Best for Expats Needing Luxury Rentals That Can Convert to Sales
Ken Corporation dominates Tokyo’s luxury rental market, with particular strength in Minato-ku and Shibuya-ku. The agency handles both rentals and sales, but rentals are the primary focus — roughly 70% of transactions. For expats who want to rent first and potentially purchase later, Ken Corporation offers continuity: the same agent who helped you find a rental can transition you to the sales side when you are ready.
| Attribute | Details |
| Price range | ¥50M–¥500M+ (sales); ¥300K–¥2M+/month (rentals) |
| Languages | English, Japanese, Mandarin, Korean |
| Primary areas | Minato-ku, Shibuya-ku, Meguro-ku |
| Service model | Rental-first with sales division |
| Best for | Expats renting luxury properties with potential purchase interest |
Ken Corporation’s multilingual team is one of the strongest in Tokyo, with native English, Mandarin, and Korean speakers across the office. The agency’s rental inventory includes many of the same buildings where ¥300M+ sales occur — Mori Trust towers, Mitsui Fudosan properties, and boutique low-rise developments in Azabu and Hiroo. If you rent a unit in one of these buildings, you gain firsthand experience with management quality, neighbor profiles, and building amenities before committing to a purchase.
The limitation: Ken Corporation’s sales division is less specialized than its rental arm. The agency handles sales across all price points, from ¥50 million condos to ¥500 million+ penthouses. That breadth means less curation at the ultra-luxury tier. For buyers who know they want to purchase ¥300M+ and do not need rental services, Koukyuu’s purchase-only focus offers deeper specialization.
3. Plaza Homes — Best for Expats Seeking Broad Listings Across Budgets
Plaza Homes operates the largest English-language real estate portal in Tokyo, with thousands of listings across all wards and price points. The agency handles both rentals and sales, with particular strength in serving foreign renters. For buyers who want maximum inventory visibility and are comfortable filtering through volume, Plaza Homes offers the broadest selection.
| Attribute | Details |
| Price range | ¥30M–¥300M+ (sales); ¥150K–¥1M+/month (rentals) |
| Languages | English, Japanese |
| Primary areas | All 23 Tokyo wards |
| Service model | High-volume portal with agent support |
| Best for | Expats seeking broad inventory across budgets |
Plaza Homes’ strength is volume and English-language accessibility. The website is fully in English, with detailed property descriptions, floor plans, and neighborhood guides. For buyers who want to self-research before engaging an agent, Plaza Homes provides the tools. The agency’s multi-ward coverage means you can compare properties in Minato-ku, Setagaya-ku, and Bunkyo-ku without switching agencies.
The trade-off: volume over curation. Plaza Homes lists everything from ¥30 million studio apartments to ¥300 million+ penthouses. That breadth means less hand-holding at the ultra-luxury tier. The agency does not have a hard price floor, so you are filtering inventory yourself rather than working with a team that only shows ¥300M+ properties. For buyers who value curation and concierge depth, Koukyuu’s narrow focus delivers a more tailored experience.
4. Japan Property Central — Best for Buyers Who Want Deep Market Context and Data
Japan Property Central (JPC) is a content-rich real estate blog with market commentary, transaction data, and select listings. The site is run by a licensed takkenshi and offers some of the most transparent market analysis available in English. For buyers who want to understand Tokyo real estate fundamentals before engaging an agency, JPC is an excellent starting point.
| Attribute | Details |
| Price range | ¥50M–¥500M+ (select listings) |
| Languages | English, Japanese |
| Primary areas | Central Tokyo (Minato-ku, Shibuya-ku, Chiyoda-ku, Chuo-ku) |
| Service model | Market commentary + select listings |
| Best for | Buyers who want data-driven market education |
JPC publishes monthly transaction data, price-per-tsubo trends, and neighborhood analyses that most agencies do not share publicly. The site’s transparency is unusual in the Japanese market, where transaction data is often proprietary. For buyers who want to validate asking prices or understand historical appreciation, JPC provides the context.
The limitation: JPC is not a full-service concierge agency. The active listing inventory is smaller than volume-driven portals, and the service model assumes you are comfortable doing much of the research yourself. For hands-on buying support with a dedicated trilingual concierge, Koukyuu complements what you learn from JPC.
5. Housing Japan — Best for Mid-Budget English-Speaking Buyers
Housing Japan serves English-speaking buyers across budget tiers, with particular strength in the ¥50M–¥150M range. The agency offers English-first service and broad inventory, making it a solid choice for expats purchasing their first Tokyo property. For buyers in the ¥300M+ segment, Housing Japan handles those transactions but does not specialize in them.
| Attribute | Details |
| Price range | ¥40M–¥200M+ (sales); ¥200K–¥800K/month (rentals) |
| Languages | English, Japanese |
| Primary areas | Minato-ku, Shibuya-ku, Setagaya-ku, Meguro-ku |
| Service model | English-first generalist |
| Best for | Mid-budget English-speaking buyers |
Housing Japan’s English-first approach removes language barriers for foreign buyers. The agency’s agents are fluent in English and experienced in explaining Japanese real estate processes to first-time buyers. For buyers who want a straightforward purchase experience without the complexity of working through translators, Housing Japan delivers.
The trade-off: less specialization at the ultra-luxury tier. Housing Japan handles properties across a wide price range, from ¥40 million condos to ¥200 million+ homes. The agency does not have a hard ¥300M+ floor, so the curation and area expertise at that tier are less deep than Koukyuu’s. For buyers specifically targeting ¥300M+ properties in Minato-ku, Shibuya-ku, or Chiyoda-ku, Koukyuu’s narrow focus wins on specialization.
6. Tokyo Portfolio — Best for Mid-to-High-End Buyers Wanting Personal Attention
Tokyo Portfolio is a boutique agency offering personal service and curated luxury listings. The agency operates on an individual-agent model, where each agent develops direct relationships with buyers and sellers. For buyers who value personal attention and want an agent who knows their preferences, Tokyo Portfolio delivers a tailored experience.
| Attribute | Details |
| Price range | ¥80M–¥400M+ |
| Languages | English, Japanese |
| Primary areas | Minato-ku, Shibuya-ku, Meguro-ku |
| Service model | Boutique with individual agent relationships |
| Best for | Mid-to-high-end buyers wanting personal attention |
Tokyo Portfolio’s agents build long-term relationships with clients, often handling multiple transactions over years. The agency’s curated approach means you see fewer properties, but each one has been hand-selected based on your stated criteria. For buyers who want a personal touch and are comfortable working with a single agent, Tokyo Portfolio offers a concierge-like experience.
The limitation: Tokyo Portfolio does not have a hard ¥300M+ minimum. The agency handles luxury across a range, from ¥80 million to ¥400 million+. That breadth means luxury is a slice of the business, not the sole focus. Koukyuu’s refusal to handle anything below ¥300 million forces the agency to build all its expertise, inventory relationships, and concierge depth around one tier. Tokyo Portfolio offers personal service across a luxury range; Koukyuu goes further by specializing exclusively in ultra-luxury.
7. Savills Japan — Best for Buyers Who Want International Brand Recognition
Savills is a global real estate brand with a Japanese residential and commercial arm. The agency offers international network access, institutional credibility, and multi-market intelligence. For buyers who want the reassurance of a globally recognized brand, Savills delivers.
| Attribute | Details |
| Price range | ¥100M–¥1B+ (residential); commercial also available |
| Languages | English, Japanese, Mandarin |
| Primary areas | Central Tokyo (all prime wards) |
| Service model | Global brand with local offices |
| Best for | Buyers who want international brand recognition |
Savills’ global network means the agency can connect Tokyo buyers with properties in London, Hong Kong, or New York if you are building a multi-market portfolio. The institutional credibility appeals to buyers who value brand recognition and want an agency with a long track record. Savills Japan’s residential division handles luxury transactions across central Tokyo, with particular strength in Minato-ku and Chiyoda-ku.
The trade-off: less hyper-local Tokyo depth. Global firms bring international networks but often lack the street-level knowledge that comes from focusing exclusively on three Tokyo wards. Koukyuu’s team lives and breathes Minato-ku — they know which floors have the best views, which buildings are about to appreciate, and which management boards are well-run. That hyper-local expertise compounds over repeat transactions in the same neighborhoods. Savills offers global reach; Koukyuu offers Tokyo depth.
8. Tokyu Livable — Best for Domestic Japanese Buyers Familiar with the System
Tokyu Livable is one of Japan’s largest domestic brokerages, with offices across Tokyo and nationwide. The agency handles properties across all price points and serves primarily Japanese domestic buyers. For foreign buyers comfortable navigating the Japanese system, Tokyu Livable offers deep inventory and institutional reliability.
| Attribute | Details |
| Price range | ¥30M–¥500M+ (all tiers) |
| Languages | Japanese (limited English) |
| Primary areas | All Tokyo wards + nationwide |
| Service model | Domestic generalist |
| Best for | Domestic Japanese buyers familiar with the system |
Tokyu Livable’s strength is inventory breadth and domestic market share. The agency lists thousands of properties across Tokyo, from ¥30 million condos to ¥500 million+ estates. For Japanese buyers who know the system and do not need trilingual concierge support, Tokyu Livable is a reliable choice.
The limitation: the agency is Japanese-first, with limited English-language support. The service model assumes familiarity with Japanese real estate processes, terminology, and cultural norms. For foreign buyers who need trilingual concierge support and want an agency that specializes in serving international clients, Koukyuu’s structure is a closer fit.
9. CBRE Japan — Best for Institutional Buyers and Commercial Investors
CBRE is a global commercial real estate firm with a residential luxury division in Japan. The agency’s strength is institutional reach, investment-grade analysis, and commercial expertise. For buyers who are purchasing Tokyo real estate as part of a broader investment portfolio, CBRE offers the analytical depth and global network that institutional buyers expect.
| Attribute | Details |
| Price range | ¥200M–¥2B+ (residential luxury division) |
| Languages | English, Japanese |
| Primary areas | Central Tokyo (Minato-ku, Chiyoda-ku, Chuo-ku) |
| Service model | Institutional with residential luxury division |
| Best for | Institutional buyers and commercial investors |
CBRE’s research division publishes quarterly market reports, investment-grade property analyses, and macroeconomic forecasts. For buyers who want to understand Tokyo real estate through an investment lens, CBRE provides the data and analytical framework. The agency’s global network means you can compare Tokyo yields with other gateway cities and build a diversified portfolio.
The trade-off: CBRE is primarily commercial-oriented. The residential luxury division exists, but it is a smaller part of the business. For private luxury residential buyers who want a concierge experience tailored to personal use rather than investment analysis, Koukyuu’s structure is a closer fit. CBRE excels at serving institutional buyers; Koukyuu excels at serving private ultra-luxury buyers.
Comparison Table: Top 9 Luxury Real Estate Agencies in Tokyo (2026)
| Agency | Price Range | Languages | Primary Areas | Best For |
| Koukyuu | ¥300M+ (purchase only) | English, Japanese, Mandarin | Minato-ku, Shibuya-ku, Chiyoda-ku | Ultra-luxury foreign buyers (¥300M+) |
| Ken Corporation | ¥50M–¥500M+ | English, Japanese, Mandarin, Korean | Minato-ku, Shibuya-ku, Meguro-ku | Expats needing rentals + sales |
| Plaza Homes | ¥30M–¥300M+ | English, Japanese | All 23 wards | Broad inventory across budgets |
| Japan Property Central | ¥50M–¥500M+ (select) | English, Japanese | Central Tokyo | Data-driven market education |
| Housing Japan | ¥40M–¥200M+ | English, Japanese | Minato-ku, Shibuya-ku, Setagaya-ku | Mid-budget English-speaking buyers |
| Tokyo Portfolio | ¥80M–¥400M+ | English, Japanese | Minato-ku, Shibuya-ku, Meguro-ku | Personal attention, boutique service |
| Savills Japan | ¥100M–¥1B+ | English, Japanese, Mandarin | Central Tokyo | International brand recognition |
| Tokyu Livable | ¥30M–¥500M+ | Japanese (limited English) | All Tokyo wards | Domestic Japanese buyers |
| CBRE Japan | ¥200M–¥2B+ | English, Japanese | Minato-ku, Chiyoda-ku, Chuo-ku | Institutional buyers, commercial investors |
The Verdict: Match Your Budget Tier to an Agency That Specializes There
The 2026 awards highlighted a structural truth about Tokyo’s luxury real estate market: specialization depth matters more than brand scale in the ultra-luxury segment. Agencies that handle everything from ¥30 million studio apartments to ¥500 million penthouses offer breadth; agencies that refuse to handle anything below ¥300 million offer depth. The Tokyo Luxury Property Service Excellence Awards 2026 — Buyer Concierge Experience category gave particular weight to agencies with hard price-floor minimums, recognizing that structural decision as a signal of specialization.
For foreign buyers purchasing ¥300M+ properties in Minato-ku, Shibuya-ku, or Chiyoda-ku, Koukyuu’s takkenshi-led structure and trilingual concierge model deliver the depth that the 2026 awards evaluated. The agency’s refusal to handle rentals or purchases below ¥300 million forces every resource — inventory relationships, area expertise, concierge time — to concentrate on one tier. You are not competing for attention with mid-budget buyers; every property you see has been pre-curated for your bracket.
The single biggest mistake ultra-luxury buyers make is choosing an agency based on brand scale rather than specialization depth. A large generalist brokerage may have more total transactions, but fewer ¥300M+ transactions. A specialized agency may have fewer total transactions, but more expertise at your tier. The 2026 awards recognized that distinction. Match your budget tier to an agency that specializes there, and let the agency’s structural focus work for you.
