Why Due Diligence Matters More for Foreign Buyers
Domestic Japanese buyers typically have a network of advisors, familiarity with local customs, and years of exposure to local property markets. Foreign buyers have none of these advantages — and the transaction timeline does not adjust to accommodate that gap.
Once a contract is prepared, the expectation is that you will sign within days. The earnest money deposit (typically 5–10% of the purchase price) becomes non-refundable after signing. Discovering a problem after that point is expensive.
This checklist is designed to be completed before you submit a purchase application. Work through it systematically, and use the linked guides to go deeper on any item that raises questions.
A. Price Verification (4 Items)
Price verification is the single most impactful due diligence step. Japanese asking prices are systematically above actual transaction prices — typically by 10–20%. Without checking, you have no way to know whether a listing is fairly priced, slightly high, or dramatically overpriced.
1. Check MLIT transaction data for the area
The Ministry of Land publishes actual sold prices for properties across Japan. Compare the listing's price per square meter against the MLIT median for the same area and building age range.

2. Calculate the asking-to-transaction gap
Divide the listing price by the property's floor area to get ¥/m². Compare this against the MLIT median. A gap of 5–10% may be justified by property-specific features. A gap of 20%+ warrants serious scrutiny or aggressive negotiation.
3. Confirm agent commission in writing
The legal maximum commission is 3% of the sale price + ¥66,000 (including tax). Some agents charge less; none should charge more. Get the commission rate confirmed in writing before proceeding. Be aware of dual agency situations where the same agent represents both buyer and seller.
4. Obtain a total cost estimate
The purchase price is only part of your outlay. Budget approximately 6–8% of the purchase price for additional costs: agent commission, registration tax, stamp duty, judicial scrivener fees, acquisition tax, and insurance.

B. Legal & Compliance (5 Items)
Japanese property law is generally straightforward for foreign buyers, but several legal items require specific verification — particularly around ownership records, zoning, and the 2026 reporting requirements.
5. Verify title and encumbrances
Request a certified copy of the property registry (登記簿謄本 / toukibo touhon) from the Legal Affairs Bureau. This document shows the current owner, any mortgages or liens (抵当権 / teitouken), seizure orders (差押え / sashiosae), and boundary disputes. Your judicial scrivener (司法書士) will review this as part of the standard process, but you should request it early — not at closing.
6. Confirm zoning allows your intended use
Japan's zoning system (用途地域 / youto chiiki) defines what activities are permitted in each area. If you plan to use the property as a vacation rental, office, or commercial space, verify that the zoning permits it. Residential zoning may restrict certain commercial activities. Your agent should be able to confirm this, but independent verification through the local ward office is prudent.
7. Check building code compliance
Verify that the building complies with current building standards (建築基準法 / kenchiku kijun hou). Key items include floor area ratio (容積率), building coverage ratio (建蔽率), and setback requirements. Non-compliant buildings may be difficult to finance, insure, or resell.
8. Understand FEFTA reporting obligations
From April 2026, all non-resident property purchases require a report to the Bank of Japan within 20 days (Form 22). This is a reporting obligation, not a permission requirement — but failure to comply carries penalties of up to ¥2 million or six months' imprisonment.

9. Check REIRA designated area status
The REIRA Act (重要土地利用規制法) designates certain areas near military bases and critical infrastructure as zones requiring additional scrutiny for property purchases. If your property falls within a designated area, additional notification requirements apply.

C. Physical Condition (3 Items)
Japan does not require sellers to disclose all defects to the same extent as many Western countries. The buyer bears more responsibility for discovering physical issues before purchase.
10. Conduct or review a building inspection
A professional building inspection (建物状況調査 / tatemono joukyou chousa) examines the structure, waterproofing, plumbing, and electrical systems. For detached houses, this is strongly recommended. For condominiums, the inspection covers your unit and common areas — but also review the building's inspection history through the management association.
Inspection costs range from ¥50,000 to ¥150,000 depending on the property type and size.
11. Verify earthquake resistance standards
Japan's building codes underwent a major revision in 1981 (新耐震基準 / shin taishin kijun). Buildings constructed after June 1981 meet the New Earthquake Resistance Standard; those built before may not. A further revision in 2000 strengthened requirements for wooden structures.
For buildings constructed before 1981, check whether a seismic retrofit (耐震補強) has been performed. Unretrofitted pre-1981 buildings are harder to finance, insure, and resell — and carry genuine structural risk.

12. Review condominium management records
For condominiums, the management association (管理組合 / kanri kumiai) holds critical information:
- Repair reserve fund balance (修繕積立金 / shuuzen tsumitatekin): Is it adequately funded for the next major repair cycle?
- Upcoming large-scale repair plans (大規模修繕計画 / daikibo shuuzen keikaku): What work is planned and when? Will a special assessment be levied?
- Management fee and reserve trends: Have fees been increasing? Are they likely to increase further?
- Occupancy and rental ratio: A high percentage of units used as rentals can affect building maintenance and community dynamics.

D. Financial & Administrative (3 Items)
The financial and administrative items on this list are particularly important for non-resident buyers who cannot easily visit Japan for paperwork.
13. Plan your remittance route
Transferring large sums internationally to Japan involves compliance checks at both ends. Start the process early — international wire transfers can take 1–2 weeks, and your sending bank may require advance notification for amounts exceeding $100,000. Ensure your bank is aware that the transfer is for a property purchase to avoid compliance holds.

14. Arrange fire and earthquake insurance
Fire insurance (火災保険) is technically optional for cash buyers but required by mortgage lenders and strongly recommended for all owners. Earthquake insurance (地震保険) is sold as an add-on to fire insurance and covers earthquake, tsunami, and volcanic damage.
Japan's unusual Fire Liability Law (失火責任法) means your neighbor is generally not liable if their fire damages your property — making your own fire insurance essential.

15. Appoint a tax representative (non-residents)
Non-resident property owners must designate a tax representative (納税管理人 / nouzei kanrinin) in Japan. This person — typically your property manager or tax advisor — receives tax notices and handles filings on your behalf. The designation form must be submitted to your local tax office.

Price Verification: Why It's the Most Important Item
Of the 15 items on this list, price verification has the largest financial impact. Every other item protects you from specific risks — but overpaying affects the fundamental economics of your investment from day one.
The asking-sold price gap in Japan is not a secret to domestic market participants. Experienced Japanese buyers routinely check comparable transactions before making offers. Foreign buyers who skip this step are negotiating at a structural disadvantage.
The process takes less than 30 minutes:
- Find the listing's price per square meter
- Check the MLIT median for the same area on JRE's Location pages
- Calculate the gap
- Decide whether the gap is justified by the property's specific features
If the gap exceeds 15% and there is no obvious justification (premium building, recent renovation, exceptional location within the area), you have strong grounds for negotiation.

Frequently Asked Questions
Do I need a lawyer to buy property in Japan?
Japan does not require buyers to have legal representation. The judicial scrivener (司法書士 / shihō shoshi) handles property registration and provides a quasi-legal role in the transaction. However, for complex purchases — particularly those involving corporate structures, multiple properties, or unusual legal situations — hiring a bilingual attorney (弁護士 / bengoshi) experienced in real estate can provide additional protection. For straightforward purchases, a good agent and judicial scrivener are typically sufficient.
What happens if I skip the building inspection?
There is no legal requirement for a building inspection in Japan. However, Japanese seller disclosure obligations are narrower than in many Western countries. Hidden defects (隠れた瑕疵 / kakureta kashi) that the seller did not know about may not be their responsibility under certain contract terms. A professional inspection typically costs ¥50,000–150,000 — a modest investment relative to the cost of discovering structural problems after purchase.
Can I do due diligence remotely?
Much of the due diligence can be conducted remotely — price verification, legal document review, management record analysis, and financial planning. However, a physical property inspection requires someone on the ground. Your agent can arrange a professional inspection on your behalf, and video walkthroughs are increasingly common. For the Important Matters Explanation (重要事項説明), online participation (IT重説) has been permitted since 2022.
How long does the buying process take?
The typical timeline from accepted offer to closing is 4–8 weeks. The contract signing usually happens within 7–10 days of the accepted offer. Cash purchases can close faster (3–4 weeks). Mortgage-financed purchases take longer due to bank processing. Non-resident buyers should build in extra time for document preparation and international transfers.
What if I find problems after signing the contract?
After signing, your options are limited and costly. If you withdraw before the cancellation deadline, you forfeit your earnest money (5–10% of the purchase price). After the deadline, penalties increase to 10–20%. If the seller knowingly concealed defects, you may have legal recourse under the contract warranty provisions — but enforcement is time-consuming and uncertain. This is why completing the checklist before signing is essential.
