Finding the right real estate agent is the single most consequential decision in a Japanese property purchase for a foreign buyer. Japan's property transaction system concentrates almost all critical information and process control through the agent. If your agent cannot — or will not — explain what is happening at each step, you are exposed. This guide explains how Japan's agent system works, how to identify trustworthy foreigner-friendly agents, what fees you will pay, and what the key documents mean.
How Japan's Agent System Works
Japan's real estate market does not use the formal buyer's agent model common in the United States or Australia. The standard structure in Japan is dual agency or split agency:
- Dual agency (双方代理, sōhō dairi): One agent represents both the seller and buyer in the same transaction. This is entirely legal in Japan and is common practice, particularly in new-build condominium sales. The agent receives commission from both sides.
- Split agency (片手, katate): The seller's agent and buyer's agent are from different companies and each represents one side. Commission is split between them.
The practical implication: in a dual agency situation, the agent's financial interest is to close the transaction, not necessarily to surface problems that would cause you to walk away. This is not unique to Japan, but the legal framework does not impose the same fiduciary duty standards on agents that some Western jurisdictions do. Your protection against this structural conflict lies in understanding the key documents yourself and asking specific questions throughout the process.
Working with an agent who specifically handles foreign buyers — and who is compensated by you for that representation — is the most reliable way to balance this dynamic. The commission is legally capped regardless of which agent you use, so there is no cost premium for working with a foreigner-specialist.
License Requirements and How to Verify Them
Japanese real estate agents must hold a 宅地建物取引士 (takuchi tatemono torihiki shi, commonly abbreviated as takken) license to conduct property transactions. This is an individual license — each licensed agent has a registration number. Brokerage offices must additionally hold a 宅地建物取引業 license issued by the relevant prefectural government or the Ministry of Land, Infrastructure, Transport and Tourism.
Offices are legally required to display their brokerage license prominently. The license number is in the format: (都)第XXXXX号 (Tokyo Governor's license) or (国土交通大臣)第XXXXX号 (Minister of Land license, for companies operating across multiple prefectures). You can verify license status through the 不動産ジャパン portal (fudousanjapan.jp) operated by the Real Estate Association of Japan.
If an agent cannot show you their office license or their personal takken certificate on request, that is a serious red flag. Licensed agents in Japan are regulated and subject to disciplinary action; unlicensed operators are not.
Types of Transactions: New Construction vs Resale
Your agent's role differs substantially depending on whether you are buying new or resale.
New Construction (新築, Shinchiku)
New-build condominiums are sold directly by the developer or through the developer's designated sales company. The agent at the model room showroom represents the developer. There is no separate buyer's agent in most new-build transactions; the buyer pays no agent fee because the developer absorbs the commission cost.
The trade-off: the agent at a developer's sales office has no incentive to flag concerns about the project, the location, or the developer's track record. Due diligence is entirely your responsibility. Ask for the 重要事項説明書 (jūyō jikō setsumeisho) in advance and review it carefully before signing any reservation agreement.
Resale Properties (中古, Chūko)
Resale transactions involve agents from licensed brokerage firms. Both dual-agency and split-agency structures occur. You will typically pay an agent commission; the seller usually pays an equal amount to their agent. The buyer's agent fee is capped by law.
For foreign buyers, the resale market is generally more transparent once you understand the key documents — the property's history, building inspection records, and management fund status are all disclosed in the jūyō jikō setsumeisho.
Agent Fees: What You Pay
Agent commissions in Japan are capped by law under the Real Estate Brokerage Act (宅地建物取引業法). The maximum fee a buyer's agent can charge is:
3% of purchase price + ¥60,000 + consumption tax (10%)
For a ¥40,000,000 property: ¥1,200,000 + ¥60,000 = ¥1,260,000 + ¥126,000 consumption tax = ¥1,386,000 total
This fee is negotiable in practice, though the statutory maximum is rarely discounted significantly in a competitive market. New-build purchases typically involve no buyer's agent fee, as the developer pays the sales commission directly.
Budget for this fee as part of your total acquisition cost. Our full condo buying guide breaks down all closing costs including agent fee, taxes, and registration expenses.
How to Find Foreigner-Friendly Agents
National Chains with International Desks
Several major real estate chains maintain dedicated international buyer desks and are a reliable starting point:
- Mitsui Fudosan Realty (三井不動産リアルティ): Large inventory, well-established English-speaking team in major urban offices
- Sumitomo Real Estate (住友不動産販売): Strong presence across the Tokyo metropolitan area including Chiba
- Century 21 Japan (センチュリー21): Franchise network, variable quality across branches, but international desk offices in major cities are typically competent
Foreigner-Specialist Boutique Agencies
For buyers who want an agent specifically focused on international clients:
- Plaza Homes (プラザホームズ): Long-established English-language agency, primarily handles higher-end properties in metropolitan Tokyo and Yokohama; Chiba coverage more limited
- Ken Corporation (ケン・コーポレーション): Specializes in high-end rentals and sales for international executives; appropriate for premium property tier
Chiba-Specific Recommendation
For Chiba property specifically, local agencies near your target station will consistently outperform Tokyo-headquartered chains in practical knowledge. An agent who operates primarily in Funabashi will know which buildings have well-funded repair reserves, which landlords in the area are responsive, and which micro-locations have had recent issues — information that no national database captures. When evaluating local agencies, ask directly whether they have handled transactions for foreign buyers before and request an example (even anonymized) of how they handled the jūyō jikō setsumeisho explanation for a foreign client.

Red Flags and Green Flags
Red Flags
- Pressure to decide within the viewing: Legitimate properties in Chiba's market do not disappear within hours. An agent who says "you need to decide today or lose it" is using pressure tactics, not managing real scarcity.
- Reluctance to share the 重要事項説明書 in advance: The jūyō jikō setsumeisho must be provided before contract signing, but there is no legal reason it cannot be shared for review earlier. An agent who resists early disclosure may be managing information flow to prevent you from identifying problems.
- Pushing specific properties without asking about your needs: An agent who emails you listings before understanding your requirements, budget, and timeline is working from inventory, not from your interest.
- Unable to explain building management fund status: For condo purchases, an agent who cannot tell you the current balance of the 修繕積立金 (shūzen tsumitatekin, repair reserve fund) has either not looked or does not know what to look for. Both are problems.
Green Flags
- Asks detailed questions about your life situation: Commute requirements, work-from-home frequency, family plans, noise sensitivity — a good agent uses this information to filter their recommendations genuinely.
- Proactively explains the 重要事項説明書: A foreigner-experienced agent will walk you through the disclosure document section by section without being prompted. This is where deal-breaking information lives.
- Patient with timeline: Foreign buyers often need more time to arrange financing, consult with overseas family members, or simply understand the market. An agent who is comfortable with a longer search cycle and does not rush you toward a commitment is working in your interest.
- Connects you with other service providers: A well-networked agent can refer you to a bilingual judicial scrivener, a home inspector, and a tax accountant — not because they receive referral fees (which is regulated), but because they maintain professional relationships for their clients' benefit.
The 重要事項説明書 — Property Disclosure Document
Every buyer in Japan must receive the 重要事項説明書 (jūyō jikō setsumeisho, commonly abbreviated JJS) before signing the purchase contract. This document is prepared by the licensed takken agent and must be explained verbally in a face-to-face meeting.
The JJS is where material facts about the property are legally disclosed. Key sections to review:
- Legal designation of the land: zoning category (用途地域), building coverage ratio, floor area ratio — these determine what can be built on and around the property
- Encumbrances: any mortgages, liens, easements, or registered rights on the property that will survive transfer
- Building specifications: construction date, structural type, earthquake resistance standard (pre- or post-1981 seismic code)
- Building management information (for condos): management fee amounts, repair reserve fund balance, outstanding special assessments, history of large repairs, upcoming planned repairs
- Surrounding development plans: known planned construction projects near the property that could affect light, noise, or views
- Defects and known issues: any disclosed structural defects, water damage history, or legal violations
If you cannot understand the JJS in Japanese, you need either an agent who explains it in English or an independent translator to review it before you sign. This document is your primary legal protection in the transaction. Treat it as such.
Working Without Japanese
Some agents offer English-language contracts; others work entirely in Japanese and use professional translators at the JJS explanation stage. Before you spend time viewing properties with an agent, confirm:
- Whether the JJS explanation will be available in English
- Whether the sale contract (売買契約書) will be provided in both languages
- Who covers translation costs (typically the buyer if a third-party translator is engaged)
Professional real estate translators with Japan market knowledge are available in Tokyo and Chiba for these purposes. A ¥30,000–¥50,000 translation fee for a ¥30,000,000+ property transaction is a justified expense.
Bottom Line
Japan's dual-agency norm means your agent may not be working exclusively for you. Protect yourself by understanding the jūyō jikō setsumeisho before you sign, verifying your agent's takken license, and choosing an agent with documented experience handling foreign buyer transactions. For Chiba specifically, local agents near your target area will outperform national chains on local market knowledge. The statutory commission cap of 3% + ¥60,000 + tax applies regardless of which agent you use — so there is no cost reason to compromise on expertise and foreign-buyer experience.
