Important Matters Explanation Document (Juuyou Jikkou Setsumeisho) Guide for Foreign Buyers in Japan

Buying property in Japan involves several critical legal steps, and one of the most important is the Important Matters Explanation (重要事項説明書, Juuyou Jikkou Setsumeisho). This mandatory document — sometimes called the "Article 35 document" — is a detailed legal disclosure that your real estate agent must provide and verbally explain before you sign any purchase agreement. For foreign buyers, understanding this document is essential to protecting your investment and avoiding costly surprises down the road.

This guide breaks down everything you need to know about the Juuyou Jikkou Setsumeisho: what it contains, how to read it, what to watch out for, and how to navigate the process as a non-Japanese speaker.

What Is the Juuyou Jikkou Setsumeisho?

The Juuyou Jikkou Setsumeisho (重要事項説明書) is a legal disclosure document that is mandatory under Article 35 of Japan's Real Estate Transaction Business Act (宅地建物取引業法). It is prepared by the real estate brokerage and must be presented and orally explained by a licensed real estate transaction specialist (宅地建物取引士, takken-shi) before the buyer signs the sales contract.

The document's purpose is to ensure buyers — particularly those with limited knowledge of Japanese real estate law — fully understand what they are purchasing and the legal conditions attached to the property. By law, the licensed agent must show their registration certificate during the explanation.

The document typically runs 20 to 100 pages and covers everything from property title and zoning restrictions to environmental hazards and condo management fees. For foreign buyers, this is often the most daunting part of the purchase process, but it is also your best legal protection.

Key terminology:

  • 重要事項説明書 (Juuyou Jikkou Setsumeisho) — Important Matters Explanation Document
  • 宅地建物取引士 (Takken-shi) — Licensed Real Estate Transaction Specialist
  • 第35条書面 (Dai-sanjuugo-jou Shomen) — Article 35 Document (another name for the same document)

When and How the Explanation Takes Place

The Important Matters Explanation must legally occur before you sign the purchase contract. Traditionally, this was required to happen face-to-face (taimen setsumei), but the rules have been updated:

Online Explanations (IT重説 / IT Juusetsu)

Since regulatory changes were introduced, the Important Matters Explanation can now be conducted online via video conference — a significant improvement for overseas buyers and expats. This is known as IT重説 (IT Juusetsu). The requirements are:

  • Both parties must be able to see and hear each other in real time
  • The buyer must have access to the electronic document
  • The agent must confirm the buyer can read the document before starting

This means you can now participate in the explanation from abroad without needing to fly to Japan, which has made property purchases much more accessible for non-resident foreigners.

Tips for Foreign Buyers During the Explanation

  1. Request the document in advance — Ask your agent to send the document 2-3 days before the explanation session so you can review it at your own pace.
  2. Bring an interpreter — The document is in Japanese. If your Japanese is not strong, hire a professional interpreter or use a bilingual agent.
  3. Take notes and ask questions — The verbal explanation is your chance to clarify anything you don't understand. No question is too basic.
  4. Don't feel pressured to sign immediately — You are legally entitled to take time to review. Never sign on the spot if you have doubts.

The Four Main Sections of the Document

The Juuyou Jikkou Setsumeisho is organized into four broad areas. Understanding this structure will help you navigate even a Japanese-language version:

SectionWhat It Covers
1. Real Estate Company InformationBrokerage license number, agent credentials, transaction specialist registration
2. Property DetailsAddress, land/building size, ownership type, zoning, infrastructure, disaster risk
3. Transaction TermsPurchase price, deposit, payment schedule, cancellation conditions, penalties
4. Other ClausesLoan conditions, seller liability, condo rules, environmental concerns

Section 1: Real Estate Company Information

This section identifies the brokerage handling the transaction and the specific licensed agent (takken-shi) responsible. The agent must present their transaction specialist certificate at the start of the explanation. Verify the license is valid — you can check on Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) database.

Section 2: Property Details

This is the most detailed and critical section. Key items include:

  • Land registration — Ownership type (freehold/leasehold), any provisional registrations
  • Zoning — Classification such as Category 1 Residential, Commercial, Industrial, etc.
  • Road frontage — Properties must front a road of at least 4 meters with at least 2 meters of contact to legally rebuild
  • Utilities — Whether water, sewage, gas, and electricity are connected
  • Disaster hazard zones — Flood, landslide, tsunami, and liquefaction risk designations
  • Earthquake resistance — Whether the building meets post-1981 seismic standards (新耐震基準)
  • Soil contamination — Especially relevant for former industrial, dry cleaning, or pesticide plant sites

Section 3: Transaction Terms

This section covers the financial and contractual details:

  • Earnest money (手付金, tetsukekin) — Amount, and whether it is refundable if the deal falls through
  • Loan approval cancellation clause (融資利用の特約) — Your right to cancel and receive a full refund if your mortgage is not approved
  • Breach of contract penalties — What happens if either party defaults

Section 4: Other Clauses

For condominium purchases, this section is especially important as it covers:

  • Monthly management fees and repair reserve funds
  • Homeowner's association (管理組合, kanri kumiai) rules
  • Planned large-scale repairs and the current reserve fund balance
  • Parking rights and usage conditions

Red Flags and Critical Items to Check

When reviewing the Juuyou Jikkou Setsumeisho, pay special attention to these high-risk items:

  • Existing mortgages — The seller's mortgage must be cleared at the time of transfer. Confirm this will happen.
  • Provisional registrations (仮登記) — These can cloud the title and create legal disputes.
  • Easements (地役権) — Agreements giving neighbors rights to cross or use part of the land.

Property and Building Issues

  • Past suicides or unnatural deaths — Agents are legally required to disclose if someone died on the property within a certain period (typically 3 years for rentals, with no fixed rule for sales but disclosure is expected).
  • Asbestos — Older buildings (pre-2006) may contain asbestos; the document should note whether an investigation has been done.
  • Soil contamination — Former gas stations, dry cleaners, or industrial facilities may have contaminated soil.
  • Building permit violations — Additions or structures built without proper permits (mikansei kensetsu, 未完成建設).

Financial Red Flags

  • Large unpaid repair reserve funds — For condos, check if there is a shortfall in the repair reserve.
  • Planned special assessments — Upcoming large repair projects that will require additional payments from owners.
  • Low-traffic roads below 4 meters — If the road in front of the property is less than 4 meters wide, you may be required to set back the building line (setback, 道路後退), effectively reducing your usable land area.

Documents Required from Foreign Buyers

To complete the transaction, foreign buyers need to provide specific documentation depending on whether they reside in Japan or abroad:

Residency StatusRequired Documents
Living in JapanResidence card (在留カード), residence certificate (住民票), seal certificate (印鑑証明書), passport
Living AbroadNotarized address proof with Japanese translation, signature certificate (from notary or Japanese embassy), passport (certified copy), domestic contact address in Japan

Important 2024 regulatory update: As of April 2024, non-resident foreigners purchasing property in Japan are required to register a domestic contact address (国内連絡先) in Japan. This can be a friend, relative, or professional representative's address.

2025 update: From July 1, 2025, foreigners making certain large land transactions are required to file a report disclosing their residency status with the government under amendments to the Foreign Exchange and Foreign Trade Act.

After the Explanation: What Happens Next

Once the Important Matters Explanation is complete and you are satisfied with the information provided, the next steps are:

  1. Sign the Important Matters Explanation Document — You will be asked to sign and seal (or signature-equivalent for foreigners) to acknowledge receipt and understanding.
  2. Sign the Sales Purchase Agreement (売買契約書, baibai keiyakusho) — This is typically done immediately after or at the same session.
  3. Pay the earnest money deposit (手付金) — Usually 5-10% of the purchase price, paid on the day of contract signing.
  4. Apply for your mortgage (if applicable) — Final loan approval typically takes 2-4 weeks.
  5. Settlement and registration (決済・登記) — Final payment, key handover, and ownership registration at the Legal Affairs Bureau.

Practical Tips for Foreign Buyers

Work with a Bilingual Agent or Lawyer

The single most effective way to navigate the Juuyou Jikkou Setsumeisho is to work with a bilingual real estate agent or hire a bilingual judicial scrivener (司法書士, shiho shoshi) to review the document with you. Many agencies specializing in foreign buyers offer English-language support throughout the process.

Use the IT Juusetsu Option

If you are purchasing from abroad, confirm with your agent that they can conduct the explanation online. Most major agencies now offer this service, and it can save you a costly trip to Japan just for the explanation.

Do Not Rush

The Important Matters Explanation is your strongest legal protection as a buyer. Take the time to understand every section. If something is unclear, ask for clarification or bring in a specialist before signing.

Keep Copies of Everything

Make sure you receive signed copies of both the Important Matters Explanation Document and the Sales Purchase Agreement. These are essential documents for future legal or tax purposes.

For additional perspective on the entire buying experience as a foreigner, the detailed article at Japan Real Estate Resources provides a thorough breakdown from a licensed agent's perspective. You can also read the MailMate guide to the Important Matters Explanation Document for a clear English-language overview.

The Juuyou Jikkou Setsumeisho is one of the most important documents you will encounter when buying property in Japan. It is your legal right to receive a thorough, verbally-delivered explanation of every item it contains — and as a foreign buyer, you should take full advantage of this protection. Request the document early, bring an interpreter or bilingual specialist, and never hesitate to ask questions.

Understanding this document will not only protect you from legal and financial risks, but it will also give you the confidence to complete your Japanese property purchase with clarity and peace of mind.
