In the context of the Japan Takken Exam (Real Estate Transaction Specialist), dual agency—often referred to in practice as Ryogawa Chukai—occurs when a single real estate broker represents or acts as an intermediary for both the seller and the buyer in the same transaction. While common in the Japanese market, it is strictly regulated to prevent conflicts of interest and the exploitation of consumers.
The core rule for the Takken Exam is found in Article 108 of the Civil Code of Japan, which generally prohibits "self-contracting" and "representation of both parties" unless the principal has given prior consent or the act involves the fulfillment of an obligation. For Takken practitioners, navigating this requires a precise understanding of the distinction between "Agency" (Dairi) and "Intermediation" (Baikai), as well as the commission limits established under the Building Lots and Buildings Transaction Business Act.

The following official resources provide the statutory basis for real estate agency and brokerage rules in Japan. Candidates should treat these as the final authority on legal definitions and practitioner requirements:
What Dual Agency Means in the Takken Exam
For the purpose of the Takken Exam, "Dual Agency" is analyzed through two distinct legal lenses: the Civil Code (general rules of agency) and the Takken Business Act (specific industry regulations).
1. Civil Code Article 108 (The Prohibition)
The Civil Code focuses on Dairi (Representation/Agency). It stipulates that a person cannot act as an agent for the other party in a contract to which they are already a party (self-contracting), nor can they act as an agent for both parties (dual agency). However, there are two major exceptions:
- If the principal(s) provided prior consent to the arrangement.
- If the act is merely the performance of an obligation (e.g., the final signing of a document where all terms were previously agreed upon).
2. Intermediation (Baikai) vs. Agency (Dairi)
Most real estate transactions in Japan are Baikai (Intermediation). Unlike Dairi, where the broker has the power to sign on behalf of the client, an intermediary simply introduces parties and facilitates the deal. Dual intermediation is generally permitted and is the standard model for many large Japanese brokerages, provided the broker fulfills their duty of disclosure.
Compliance Note: Even in dual intermediation, the broker owes a fiduciary-like duty to both parties. They must provide the "Explanation of Important Matters" (Article 35) honestly to both the buyer and the seller.
Commission Limits and Dual Agency
One of the most frequent calculation questions on the Takken Exam involves commission (Houshu) limits. In a dual agency or dual intermediation scenario, the broker must not exceed the statutory cap.
| Scenario | Seller Side Fee | Buyer Side Fee | Total Statutory Limit |
|---|---|---|---|
| Single-Sided (Standard) | 3% + 60,000 JPY* | N/A | 3% + 60,000 JPY |
| Dual Intermediation (Ryogawa) | 3% + 60,000 JPY* | 3% + 60,000 JPY* | Double the single-sided cap |
| Dual Agency (Dairi) | Varies | Varies | Double the single-sided cap (Total) |
*Note: This applies to transaction values over 4 million JPY, excluding consumption tax. Please verify current consumption tax rates and minor fee adjustments on the MLIT website.
What Candidates Get Wrong
In the heat of the exam, candidates often conflate the rules of the Civil Code with the business practices of the Takken Act. Avoid these common pitfalls:
- Assuming Dual Agency is Illegal: Many students think Article 108 is an absolute ban. It is not. With consent, it is legally valid.
- Confusing Agency and Intermediation: If the exam question uses the word Baikai (Intermediation), Article 108’s prohibition on dual representation does not apply in the same way it does to Dairi.
- Mathematical Errors in Commissions: In a "Dual Agency" (Dairi) situation, a broker can receive a total commission up to twice the amount of a standard single-sided intermediary fee, but they cannot collect this "double fee" from a single party unless specifically agreed and within the total cap.
- Ratification: Remember that even if a broker acts as a dual agent without prior consent, the contract is not automatically void; it is "unauthorized agency" (Mugen Dairi) and can be ratified later by the principals.
Practical Exam-Prep Takeaways
- Keyword Identification: When reading a question, immediately identify if the broker is acting as an "Agent" (Dairi) or an "Intermediary" (Baikai).
- Consent is King: In Civil Code questions regarding Article 108, "prior consent" is almost always the factor that makes a dual-party action legal.
- Article 35 & 37: Even in dual agency, the broker must deliver the Article 35 (Important Matters) and Article 37 (Contract Document) papers to both parties. You cannot skip one side just because you represent both.
