Japan Real Estate Agent Duties and Legal Obligations: What Every Foreign Buyer Must Know

When buying property in Japan as a foreigner, understanding what your real estate agent is legally required to do — and what protections you have — is essential. Japan has a well-regulated real estate industry governed by specific laws that define exactly what agents can and cannot do. This guide breaks down the duties and legal obligations of Japanese real estate agents so you know what to expect throughout your property purchase.

The Legal Framework: Japan's Real Estate Brokerage Law

All real estate agents in Japan operate under the Building Lots and Buildings Transaction Business Act (宅地建物取引業法, commonly called the 宅建業法 or Takken Gyoho). This law was created to ensure that real estate transactions are carried out with honesty and fairness, that properties circulate smoothly through the market, and that buyers' interests are protected.

Under this law, any business that engages in buying, selling, or intermediating real estate transactions must obtain a license. There are two types of licenses:

• Prefectural Governor License — for businesses operating within a single prefecture
• Minister of Land, Infrastructure, Transport and Tourism (MLIT) License — for businesses operating across two or more prefectures

By the end of fiscal year 2023, over 25,000 real estate brokers were licensed by the prefectural governor of Tokyo alone, illustrating the scale of the industry. Around 3,000 brokers held MLIT licenses enabling multi-prefecture operations.

The Real Estate Notary: Japan's Unique Licensed Professional

One of the most distinctive aspects of Japan's real estate system is the Real Estate Notary (宅地建物取引士, Takken-shi), sometimes called a Real Estate Transaction Specialist. This is a nationally licensed professional who must be present at certain critical stages of every property transaction.

Who Are They?

A Real Estate Notary has passed Japan's national real estate examination and is qualified to perform legally mandated tasks that non-certified staff cannot perform. Companies engaged in real estate transactions must maintain a minimum ratio of at least one qualified Real Estate Notary for every five employees. This requirement ensures a baseline of expert oversight across the industry.

What They Must Do by Law

Real Estate Notaries have two primary duties that are legally mandated:

1. Explain the Important Matters Document (重要事項説明, Jūyō Jikō Setsumeisho) — Before a contract is signed, the notary must personally explain the contents of this document to the buyer in detail.
2. Affix Name and Seal to Contract Documents — The notary must sign and seal the important matters document and the transaction contract, creating a formal legal record.

These are not optional procedures — they are required by law for every transaction.

The Explanation of Important Matters (重要事項説明)

The Explanation of Important Matters is the cornerstone of buyer protection in Japanese real estate transactions. This document — typically ranging from 20 to 100 pages — covers all legally required disclosures about the property and the transaction terms. The Real Estate Notary must explain each item verbally to the buyer before the contract is signed.

Key items covered in the Explanation of Important Matters include:

As a foreign buyer, you have the legal right to request a bilingual explanation. While the document itself will be in Japanese, a qualified bilingual agent or interpreter should accompany you. If you cannot understand the explanation, you should request a translation before signing anything.

For more on the legal process, see our Legal Procedures and Documentation for Japan Property Purchase guide.

Agent Disclosure Obligations to Buyers

Beyond the formal Explanation of Important Matters, real estate brokers in Japan have a general legal obligation to provide material information about the property in writing or by electromagnetic means to the buyer. This means:

• No omitting known defects — An agent who knows about a structural problem, past flooding, or legal encumbrance cannot legally withhold that information.
• Written disclosure required — Key information must be provided in documented form, not just verbally.
• Seller fraud doesn't exempt agents — Even if a seller tries to hide information through fraudulent misrepresentation, the broker may still bear liability if they had reasonable means to discover and disclose the issue.

This stands in contrast to sellers themselves, who in Japan have a more limited formal disclosure duty. Brokers fill the gap as the primary vehicle for ensuring buyers receive the facts they need to make informed decisions.

Commission Fees: What Agents Can Legally Charge

Real estate agent commissions in Japan are legally capped and standardized. Agents cannot charge more than the legally permitted maximum, which is calculated as follows:

Important 2024 update: As of July 1, 2024, a new rule raises the brokerage fee cap to ¥300,000 before tax for properties priced up to ¥8 million. Previously this cap only applied to properties under ¥4 million. This change was made to encourage the circulation of vacant homes and lower-priced used properties, which had been sitting unsold due to insufficient incentive for agents to handle low-value transactions.

One unique and important fact: Japan legally permits dual agency, meaning a single real estate company can legally receive commission from both the buyer and the seller in the same transaction. This is called a ryō-te torihiki (両手取引). While this would be considered a serious conflict of interest in many Western countries, it is standard and legal practice in Japan. Be aware that your agent may be simultaneously representing the seller's interests.

Special Duties When Working with Foreign Buyers

Real estate agents working with foreign nationals have additional practical (and increasingly legal) responsibilities:

Language Assistance

All contracts and legal documents in Japan are written exclusively in Japanese. Agents working with foreign buyers have a professional duty to ensure their clients understand what they are signing. In practice, this means:

• Providing translated summaries or explanations of key documents
• Using bilingual staff or certified interpreters for the Important Matters Explanation
• Ensuring you understand cancellation conditions and payment obligations

Real Estate Acquisition Report for Foreign Buyers

When a foreigner purchases land in Japan, the agent is typically responsible for assisting with filing the Real Estate Acquisition Report (土地取得届出) with the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). This is a regulatory requirement for non-Japanese buyers of land.

Upcoming 2026 Nationality Declaration Requirement

Starting in fiscal year 2026 (from April 1, 2026), foreign nationals purchasing property in Japan will be required to declare their nationality when registering the property with the government. Your agent will assist with this process. While this does not restrict the right to buy, it creates a new step in the registration procedure that agents must guide foreign clients through.

What Agents Are Prohibited From Doing

The Building Lots and Buildings Transaction Business Act also defines prohibited conduct. Real estate agents in Japan are legally forbidden from:

• Misrepresentation — Making false statements about property details, prices, or transaction terms
• Incomplete disclosure — Omitting material facts that would affect a buyer's decision
• Overcharging commissions — Charging more than the legally capped maximum
• Conducting transactions without a license — All brokerage activity requires valid licensing
• Forcing or pressuring buyers — Aggressive sales tactics that coerce buyers into unwanted transactions are prohibited

Violations can result in license suspension or revocation by the prefectural governor or MLIT. For red flags and warning signs to watch for, see our Red Flags and Scams to Watch For with Japan Real Estate Agents article.

Choosing an Agent Who Understands Foreign Buyer Needs

Understanding your agent's legal obligations is one thing — but finding an agent who actually fulfills them effectively for foreign clients requires research. Not all agents have experience with foreign buyers or English-language skills.

Key qualities to look for:

• Experience handling transactions for foreign nationals
• Bilingual staff or English-speaking Real Estate Notary
• Transparent fee structure with written commission agreements
• Familiarity with foreign buyer-specific requirements (MLIT reporting, etc.)
• Membership in professional associations such as the All Japan Real Estate Association (全日本不動産協会) or the Japan Federation of Real Estate Transaction Business Associations (不動産流通機構)
