When selling property in Japan, the baikai keiyaku (媒介契約, brokerage agreement) you sign with a real estate company is the first decision that shapes whether the sale succeeds. Japan recognizes three distinct types of these agreements, and among them the sennin baikai keiyaku (専任媒介契約, exclusive brokerage agreement) is the balanced middle option most first-time sellers choose.
This is a distinctively Japanese arrangement: unlike the single, broadly similar listing agreement used in most English-speaking markets, Japanese law defines three separate, legally distinct contract types with different registration deadlines and reporting duties. For an overseas investor selling a Japanese property, knowing which type applies is not a formality — it determines how widely your property is marketed and how exposed you are to a Japan-specific risk called kakoikomi (explained below). This guide covers the exclusive agreement, its pros and cons, commission costs converted to US dollars, and how to spot kakoikomi.
What Exactly Is a Sennin Baikai (Exclusive Brokerage) Agreement?
A sennin baikai keiyaku (専任媒介契約) lists your property with only one real estate company at a time. It still permits jiko hakken torihiki (自己発見取引, a self-found transaction) — you remain free to find your own buyer, say a friend or existing tenant, without owing the listing agent a commission on that sale. Of Japan’s three agreement types, this is the most balanced.
Channeling the listing through one company gives it a clear incentive to commit budget and effort, since no rival agent competes for the same fee. Unlike a market where signing with any licensed agent is fairly low-stakes, in Japan vetting the agent’s track record matters enormously before you sign.
The Three Types of Brokerage Agreement in Japan
Property sales in Japan use three agreement types: ippan baikai keiyaku (一般媒介契約, open listing), sennin baikai keiyaku (専任媒介契約, exclusive listing), and senzoku sennin baikai keiyaku (専属専任媒介契約, sole-exclusive listing). This three-tier system has no direct equivalent in most English-speaking markets, where one standard listing agreement is the default. Here is how the three compare.
| Feature | Open Listing (Ippan Baikai) | Exclusive Listing (Sennin Baikai) | Sole-Exclusive Listing (Senzoku Sennin Baikai) |
|---|---|---|---|
| Contracting with multiple companies | Allowed | Not allowed (one company only) | Not allowed (one company only) |
| Self-found transaction (jiko hakken torihiki) | Allowed | Allowed | Not allowed |
| REINS registration | Optional | Mandatory within 7 days | Mandatory within 5 days |
| Progress reporting | Optional | At least once every 2 weeks | At least once every week |
| Contract term | No legal limit (3 months is typical) | Maximum 3 months | Maximum 3 months |
An exclusive listing suits properties that need extra selling effort — a less convenient location, an older building, or restricted road frontage (an access-width constraint that can affect rebuilding rights under Japanese building codes). One company concentrating its resources can outperform several agents each spreading thin effort, whereas a highly desirable property in a popular area may sell better under an open listing instead.
The Mandatory REINS (レインズ) Registration
REINS (レインズ, Real Estate Information Network System) is the property database run by distribution organizations designated by Japan’s Minister of Land, Infrastructure, Transport and Tourism (MLIT, 国土交通大臣) — an agents-only database broadly comparable to a US-style MLS, though participation and disclosure rules differ. Once you sign an exclusive agreement, your agent must register your property on REINS within seven days (excluding non-business days) of signing.
Once registered, real estate companies nationwide can view your listing, which dramatically widens your pool of potential buyers. The seller then receives a toroku shomeisho (登録証明書, registration certificate), letting you verify the registration and transaction status at any time — one of the seller’s few practical defenses against kakoikomi, the buyer-blocking practice discussed later.
Why the Choice of Agreement Shapes the Entire Sale
A brokerage agreement is not administrative paperwork. Which type you choose determines how widely your property’s information travels, and how seriously your agent works for you. Listings are now compared instantly across portal sites, so pricing, presentation, and how fast an agent responds to early inquiries directly affect final price and time on market. Compared with a market where sellers mainly choose between similarly structured listing agreements, a Japanese seller’s choice among three legally distinct types has an outsized effect on outcome.
The Advantages of an Exclusive Brokerage Agreement
An exclusive agreement offers sellers three main advantages, all flowing from the same feature: entrusting the sale to one company.
Regular, Legally Mandated Progress Reports
Under an exclusive listing, the Building Lots and Buildings Transaction Business Act (宅地建物取引業法, Takken Gyōhō) requires the agent to report on progress at least once every two weeks. Reports cover inquiry volume, viewings, and buyer feedback, giving you a regular basis for adjusting price or presentation. Unlike an open listing, where reporting is optional, the guaranteed cadence is itself reassuring.
A Stronger Incentive for the Agent to Market Actively
The company knows it will earn the commission with certainty if the sale closes, since no other agent can undercut it. This makes it far more willing to spend its own budget on advertising, portal listings, and flyers to nearby residents, and one company designing the whole campaign tends to produce more consistent marketing than several competing agents.
Optional Extras Some Companies Offer Exclusive Clients
Some companies offer added services to exclusive-listing sellers, such as:
- Professional house cleaning or home staging
- A building condition survey (inspection)
- A buy-back guarantee if the property has not sold within a set period
- Coverage for equipment repair costs discovered after handover
These perks are offered at each company’s discretion and vary widely. Do not choose on perks alone — treat them as a bonus on top of a genuine assessment of selling capability.
The Drawbacks and Risks to Watch For
An exclusive agreement is not without real downsides. Being upfront about them, not only the advantages, is the first step in protecting a seller’s interests.
The Risk of Depending on a Single Company
Because an exclusive listing binds you to one company, the sale’s outcome depends heavily on that company’s competence. A company lacking marketing reach can leave you without a buyer while the term simply runs out. The remedy: before signing, compare valuations, strategy, and track record across several companies, and choose for concrete, evidence-based reasons — not the highest quoted price.
Kakoikomi: Japan’s Buyer-Blocking Risk, and How to Spot It
Kakoikomi (囲い込み) is a practice unique to Japan’s brokerage system, in which a company turns away other agents’ viewing or purchase inquiries to secure a ryōte chūkai (両手仲介, dual-agency deal) — commission from both seller and buyer on the same transaction. This has no direct equivalent in markets where dual agency is banned or tightly regulated with disclosure; in Japan it is legal but widely criticized, and is the abuse most associated with exclusive listings. Tactics include falsely claiming another offer is already in negotiation, or delaying REINS registration to keep the listing invisible — either way, you lose the chance to meet a buyer who might offer better terms, so your agent can double its fee.
What to check for:
- Confirm the REINS registration status: request the registration certificate and verify the transaction status shows as on the market, not quietly marked pending.
- Watch the viewing response rate: a well-located, relatively new property drawing almost no viewings suggests other companies’ inquiries are being blocked.
- Ask the company’s dual-agency (ryōte chūkai) rate directly: whether it answers openly is itself a useful gauge of transparency.
Brokerage Commission and Other Costs, Converted to US Dollars
Whichever agreement type you sign, once a sale closes you pay a chūkai tesūryō (仲介手数料, brokerage commission), capped by the Building Lots and Buildings Transaction Business Act. The table shows the standard formula; figures are pre-tax, with consumption tax added separately. Yen below is converted at approximately 155 JPY/USD (so ¥10,000 ≈ US$65) — check a current rate for any real transaction.
| Sale price (before tax) | Maximum commission (quick-calculation formula) |
|---|---|
| Portion up to ¥2,000,000 (approx. US$12,900) | Sale price × 5% |
| Portion from ¥2,000,000 to ¥4,000,000 (approx. US$12,900–US$25,800) | Sale price × 4% + ¥20,000 (approx. US$130) |
| Portion above ¥4,000,000 (approx. US$25,800) | Sale price × 3% + ¥60,000 (approx. US$390) |
For example, on a ¥30,000,000 (approx. US$193,500) sale, the ceiling is ¥30,000,000 × 3% + ¥60,000 = ¥960,000 (approx. US$6,200), plus consumption tax. That is strictly the legal maximum; the actual fee depends on negotiation and company policy. Because an exclusive agreement guarantees the commission, many agents compete less on discounting the fee and more on bundled service value.
Selling in Japan also involves inshi-zei (印紙税, stamp duty), mortgage-discharge registration costs, and, on a capital gain, jōto shotoku-zei (譲渡所得税, capital gains tax on the transfer). Unlike a flat capital-gains rate, Japan’s calculation depends heavily on acquisition cost, holding period, and applicable exemptions, so confirm your specific tax liability with a licensed Japanese tax accountant (zeirishi) or your local tax office — especially important for overseas owners, whose acquisition-cost records and residency status can change the calculation.
How to Choose the Right Real Estate Company for an Exclusive Listing
The single most important factor in making an exclusive agreement succeed is choosing the right real estate company, since for the full term you have no other agent to fall back on. Compare candidates against the following.
| Selection criterion | What to check |
|---|---|
| Sales track record | Number of transactions in the area, closed deals on comparable properties |
| Basis for the valuation | Whether it cites concrete data, such as comparable closed sales |
| Marketing strategy | Whether advertising methods, target buyers, and pricing-review policy are specific |
| Agent responsiveness | Speed of response, precision of answers, willingness to disclose downsides |
| Attitude toward kakoikomi | Whether the dual-agency rate is disclosed, cooperation with other agents’ buyers |
What we most want overseas sellers to weigh is whether an agent is honest enough to explain the risks, not only the upside. One who conceals inconvenient information may, when it matters, prioritize their own profit over yours. Judge the honesty of the explanation, not the height of the quoted valuation.
The Process, From Signing to Handover
It helps to know the typical path from signing to handover. As a rough guide, listing to handover often runs several months, varying with the property and market.
- Valuation and choosing a company: Request valuations from several companies, compare reasoning and strategy, and select one.
- Signing the brokerage agreement: Confirm terms, validity period, perks, and commission conditions in writing.
- REINS registration and listing launch: The property is registered within the deadline and advertising begins.
- Managing viewings and adjusting price: Using the regular progress reports, revise presentation and pricing as needed.
- Sale contract and handover: Once terms are agreed, sign the sale contract and complete settlement and handover.
INA&Associates’ View: Choosing a Brokerage Agreement Honestly
At INA&Associates K.K., we place trust and honesty above all else. In choosing a brokerage agreement, we consider it essential to disclose not just the benefits to the seller but the drawbacks too, without holding anything back. An exclusive listing suits many sellers, but it is not automatically right for every property or seller.
The decision should never be exclusive equals safe on its own. What matters is weighing your property’s characteristics, how urgently you need to sell, and the competence of the company you entrust, together. Over the long run, a partner who stays honest through to the end matters more than the highest initial valuation.
In short, an exclusive agreement lets one company concentrate its full effort on your property — efficient if you choose well, a path to kakoikomi or a stalled sale if you choose poorly. Comparing valuations from several companies, and judging them on strategy and honesty, is the key. We publish related perspectives in our full column archive.
Frequently Asked Questions
Can I cancel an exclusive brokerage agreement early?
The term runs a maximum of three months and ends automatically if not renewed. You can cancel during the term, though the company may bill actual costs already spent, such as advertising. With a legitimate reason — a failure to deliver mandated reports, or discovered kakoikomi — cancellation without penalty is generally reasonable. Check your contract’s specific clauses if unsure.
What happens if I find my own buyer?
An exclusive agreement permits jiko hakken torihiki (self-found transactions). Depending on your contract terms, though, you may still owe a fee even then, for instance if the contract ties a fee to costs the agent already incurred. Review the self-found-transaction clause carefully before signing.
Should I choose an open listing or an exclusive listing?
For a well-located, highly desirable property in a popular area, an open listing letting several companies compete can sell it perfectly well. For a property needing extra selling effort, or if you want one company driving the process quickly, an exclusive listing tends to fit better. Work backward from your property’s characteristics and how urgently you need to sell.
Will I always pay the maximum commission?
No. The law sets only a ceiling; the actual fee depends on company policy and negotiation. Because an exclusive agreement guarantees the commission, some companies offset the lack of a discount with services like house cleaning or a sale guarantee instead. Compare total value offered, not the headline number alone.
