Signing the Property Purchase Agreement in Japan: A Complete Guide for Foreigners

Signing the property purchase agreement in Japan is one of the most important — and often most nerve-wracking — steps in the home-buying journey. If you are a foreigner buying property in Japan, you will encounter unfamiliar legal documents, a mandatory pre-signing explanation session, and contracts written entirely in Japanese. Understanding what to expect before you sit down at the signing table can save you from costly mistakes and give you the confidence to proceed smoothly.

This guide walks you through every aspect of signing the 売買契約書 (baibai keiyakusho — the Sales and Purchase Agreement), from the legally required Important Matters Explanation to the costs you must pay on signing day.

What Is the Property Purchase Agreement (売買契約書)?

The 売買契約書 (baibai keiyakusho), or Sales and Purchase Agreement (SPA), is the legally binding contract between buyer and seller in a Japanese real estate transaction. Once both parties sign, the agreement creates binding obligations — the buyer is committed to purchase and the seller is committed to sell under the agreed terms.

The agreement typically covers:

• The agreed purchase price and how it will be paid
• The deposit amount and conditions for its return or forfeiture
• The scheduled closing date and possession transfer date
• Conditions for cancellation and remedies for breach
• Details of any included fixtures, appliances, or structures
• Any known defects or encumbrances on the property

Key fact: All contracts in Japan are written in Japanese, and all terms are governed by Japanese law. If you request a translated copy, the Japanese version always takes legal precedence over any translation. Work with a bilingual agent or lawyer to make sure you understand every clause before signing.

Step 1: The Mandatory Important Matters Explanation (重要事項説明)

Before you can sign the purchase agreement, Japanese law requires that a licensed real estate agent deliver and verbally explain the 重要事項説明書 (juyo jiko setsumei-sho) — commonly called the "Explanation of Important Matters" or just "Juyo Jiko."

This session is mandated by Japan's Real Estate Brokerage Act (宅地建物取引業法) and must take place before the contract signing. The document itself can run anywhere from 20 to 100 pages and covers:

The explaining agent must hold a valid 宅地建物取引士 (takken-shi) license. As the buyer, you are required to sign and seal a receipt confirming you received and understood the explanation. For foreign buyers, this session can take two to three hours if bilingual interpretation is needed.

Tip: Ask your real estate agent to share a draft copy of the Important Matters Explanation at least a few days before the meeting so you have time to review it with a translator or bilingual lawyer.

Step 2: Reviewing the Contract Before Signing Day

Do not wait until the meeting table to read the purchase agreement for the first time. A well-prepared buyer reviews the draft contract in advance and prepares a list of questions.

Key clauses to scrutinize:

Deposit and cancellation terms: Under standard Japanese contracts, if the buyer cancels after signing, they forfeit their deposit. If the seller cancels, they must return double the deposit amount. Make sure you understand these conditions clearly.

Financing contingency clause (ローン特約, loan tokuyaku): If you are financing your purchase with a mortgage, ensure a financing contingency clause is included. This allows you to cancel without penalty if your loan application is rejected.

Handover condition: Confirm exactly what will be included at handover — whether the previous owner will remove all furniture, whether certain fixtures are included, and in what condition the property should be delivered.

Defect liability (瑕疵担保責任): Under Japanese law, sellers may be liable for undisclosed defects discovered after closing. Newer contracts increasingly use the term "契約不適合責任" (contractual nonconformity liability) since the civil code update in 2020.

Step 3: What Happens on Signing Day

The signing meeting typically takes place at the real estate agency's office on a weekday and can last several hours. Here is what to expect:

1. Review of the Important Matters Explanation (if not done in a prior session)
2. Review of the Purchase Agreement — the agent walks through each clause
3. Execution of the contract — both buyer and seller sign and affix their seals to every page
4. Payment of the deposit — typically 5–10% of the purchase price
5. Payment of the real estate agent's commission — typically 3% of the purchase price plus ¥60,000 plus consumption tax (this may be split between signing and closing)

For foreigners, the signing process requires:

• If you are a resident of Japan: Residence card (在留カード), passport, and your personal seal (印鑑/inkan) or a signature depending on the agent's requirements
• If you are a non-resident: A notarized affidavit sworn before a notary public in your home country, verifying your identity and signature

The contract is executed when both parties have signed all pages and delivered their respective obligations (buyer pays deposit; seller confirms acceptance). You will leave with a fully executed copy of the contract and the Important Matters Explanation document.

Costs and Taxes Due at Signing

One of the most important things to budget for is the costs payable on or around signing day. These are separate from the final closing costs.

Important note about the deposit: In Japan, there is no neutral escrow system like in some Western countries. The deposit (手付金) is typically paid directly to the seller as a sign of good faith. This is standard practice and reflects Japan's high-trust business culture. However, it does mean that if the seller becomes insolvent before closing, recovering the deposit can be difficult — one reason due diligence before signing is critical.

Stamp Duty on the Purchase Agreement

Every purchase agreement in Japan must have a 収入印紙 (revenue stamp / inshi) affixed to it to be legally valid. The amount is determined by the contract value:

The revenue stamps are typically purchased at a post office or convenience store, then affixed and cancelled (by pressing a seal across the stamp and the document) at the signing meeting. Your agent will usually handle this logistics, but the cost is the buyer's responsibility.

Post-Signing Obligations for Foreign Buyers

If you are a non-resident foreigner purchasing property in Japan, you have an important legal obligation after signing:

Notification to the Bank of Japan / Ministry of Finance: Under the Foreign Exchange and Foreign Trade Act (外国為替及び外国貿易法), non-resident foreign buyers must submit a post-facto report to the Bank of Japan (通常の事後報告) or the Minister of Finance within 20 days of acquiring the property. This report includes:

• Your full name, address, and nationality
• The property address and purchase price
• The transaction date

Your real estate agent or a 司法書士 (judicial scrivener / shiho shoshi) can assist with this filing. Failure to report can result in fines, so do not overlook this step.

Working with Professionals: Why Bilingual Support Matters

For foreign buyers, the most valuable investment you can make is in strong bilingual professional support. The purchase agreement and Important Matters Explanation are dense legal documents in Japanese. Even buyers with intermediate Japanese skills can miss critical nuances.

Consider engaging:

• A bilingual real estate agent who regularly works with foreign clients and can explain documents in English
• A 司法書士 (judicial scrivener) who handles registration of the title transfer after closing — some also provide bilingual services
• A 弁護士 (bengoshi / lawyer) for complex transactions, particularly commercial properties or properties with legal complications

From Signing to Closing: What Comes Next

After the purchase agreement is signed and the deposit is paid, the timeline to closing (the final settlement and title transfer) typically runs 30 to 60 days. During this period:

1. Mortgage processing (if applicable): Your lender finalizes the loan; an appraisal may be conducted
2. Pre-closing inspection: You may request a walkthrough of the property
3. Closing meeting: Held at the bank or the title agent's office, usually with a judicial scrivener present; you pay the remaining balance, all closing taxes and fees, and sign the title transfer documents
4. Title registration: The 司法書士 registers the ownership transfer at the Legal Affairs Bureau (法務局) on the closing day
