Every property purchase in Japan passes through a single legal checkpoint that has no direct equivalent in the United States, the United Kingdom, Australia, or most of continental Europe. Before a sales contract can be signed, a licensed specialist must sit with the buyer, document in hand, and explain the material facts of the transaction in full. Miss this step, and the broker commits a criminal offence under Japanese statute. For foreign buyers approaching Tokyo’s luxury market, understanding this process before you reach the signing table is not optional housekeeping. It is the difference between a clean acquisition and a costly dispute.

What Juyou Jikou Setsumei Actually Is

The 重要事項説明 (juyou jikou setsumei, the statutory pre-contract disclosure meeting) is mandated by Article 35 of the 宅地建物取引業法 (Takuchi Tatemono Torihiki Gyoho, Japan’s Real Estate Brokerage Act), administered by the 国土交通省 (Ministry of Land, Infrastructure, Transport and Tourism, known as MLIT). The document itself is called the 重要事項説明書 (juyou jikou setsumei-sho, the written Important Matters Explanation Document), and is colloquially shortened to 重説 (jusetsu) in professional usage.

The legal requirement is precise: a 宅建士 (takken-shi, Japan’s licensed real-estate transaction specialist) must personally explain the document’s contents to the buyer before the sales contract is executed. The buyer cannot waive this right. The takken-shi must be present, must identify themselves with their licence, and must answer questions. Failure by the brokerage to conduct the session is a criminal violation of the same statute.

For foreign buyers, the immediate practical implication is significant. The document is issued in Japanese only. No statutory obligation exists requiring brokers to provide an English translation. Buyers who do not read Japanese are legally entitled to the same session as everyone else, but the content will arrive in a language most of them cannot parse independently. Retaining a bilingual takken-shi or independent legal counsel to review the document before the session is not a luxury at this price point. It is due diligence.

For a broader orientation to how property acquisition works in Japan from a foreigner’s perspective, the Koukyuu guide to buying property in Japan as a foreigner covers the full transaction sequence, including mortgage access for non-residents and visa considerations.

What the Document Must Disclose

Article 35 specifies a minimum checklist of disclosure items. For Tokyo luxury マンション (manshon, Japanese usage: freehold condominium, distinct from the English word ‘mansion’) purchases, the relevant categories include the following.

Property identification and registry records. The 登記 (touki, the transfer of legal title recorded at the Legal Affairs Bureau) history, existing 抵当権 (teitouken, mortgages), liens, and easements must all appear. If the seller carries an outstanding mortgage, the document must confirm it will be discharged at settlement. Buyers should read this section with particular attention: an undisclosed encumbrance that survives closing is a title defect. Statutory restrictions. The 用途地域 (yoto chiiki, zoning classification) determines what can be built on or done with the land. For buyers considering short-term rental income, this section is critical. 民泊 (minpaku, short-term residential rental under Japan’s Minpaku Law) is prohibited in many residential zones across Minato-ku (港区) and Shibuya-ku (渋谷区). The document must state the zoning class, the 建蔽率 (kenpei-ritsu, building coverage ratio), and the 容積率 (yoseki-ritsu, floor-area ratio). Management fees and repair reserves. For high-end Tokyo condominiums, 管理費 (kanri-hi, monthly building management fees) and 修繕積立金 (shuuzen tsumitate-kin, the long-term repair reserve fund contribution) are often substantial. Combined monthly charges of ¥50,000 to ¥200,000 or more are common in premium buildings across Azabu (麻布), Hiroo (広尾), and Roppongi Hills. The jusetsu must state current amounts and any scheduled increases. Buyers should also request the 長期修繕計画 (chouki shuuzen keikaku, the long-term repair plan) and verify the reserve fund balance separately. Flood hazard map disclosure. Added to the mandatory checklist in April 2020 following amendment of the 水防法 (Suibo-ho, Flood Control Act), brokers must now show the buyer the property’s location on the municipal 水害ハザードマップ (suigai hazard map, flood risk map). This applies to every transaction regardless of perceived flood risk. Embankment regulation status. From November 2023, following enactment of the 盛土規制法 (Mori-do Kisei-ho, Embankment Regulation Act), brokers must disclose whether a property falls within a 規制区域 (kisei kuiki, regulated embankment zone). As of April 2026, municipalities are still completing zone designations. Hillside properties in Minato-ku, 目黒区 (Meguro-ku), and 世田谷区 (Setagaya-ku) are particularly relevant here. Buyers of properties on elevated or terraced sites should verify current zone status directly with the relevant 都道府県 (to-do-fu-ken, prefectural authority). Contract cancellation and cooling-off rights. The document must state the クーリングオフ (cooling-off) conditions. Under Article 37-2 of the Real Estate Brokerage Act, buyers who conclude a purchase away from the broker’s registered office, including at a hotel or via video call, retain an 8-day right to rescind the contract without penalty. This right must be disclosed in the jusetsu and is directly relevant to foreign buyers transacting remotely. Defect liability. Following revision of Japan’s 民法 (Minpo, Civil Code) effective April 2020, defect liability is now framed as 契約不適合責任 (keiyaku futekigo sekinin, liability for non-conformity with contract). The jusetsu must state the scope and duration of this liability as agreed between the parties. For resale properties, buyers should confirm what inspection reports, if any, have been conducted and whether results are attached.

The 2026 Regulatory Landscape: What Has Changed

Three developments from the past two years are directly relevant to foreign buyers transacting in Tokyo in 2026.

IT重説: Remote Sessions Are Now Permanent

Effective May 18, 2022, MLIT amended the Real Estate Brokerage Act to permit 電磁的方法 (denjitek-teki hoho, digital/electronic delivery) of the jusetsu document, provided the buyer consents in writing. The mandatory explanation session can now be conducted via video conference under the IT重説 (IT-jusetsu, remote important-matters explanation) framework, made permanent for all transaction types from that date. As of 2026, electronic signatures on the jusetsu document are also accepted, removing the final barrier to a fully remote closing.

For buyers based in Singapore, Hong Kong, London, or New York who are acquiring Tokyo property without being physically present, this is consequential. The session can proceed via video call, provided the buyer has received the document in advance and confirms receipt before the session begins. The takken-shi must still hold a valid licence and must be identifiable on screen.

Embankment Zone Designations Still Incomplete

The Mori-do Kisei-ho has been in force since May 26, 2023, but as of April 2026, many municipalities have not yet finalised their regulated zone maps. This creates a disclosure gap: a broker may state that no designation has been confirmed, which is technically accurate but does not mean the property is clear. Buyers of properties on slopes or filled land should commission an independent site investigation rather than relying solely on the jusetsu disclosure.

FY2026 Tax Reform and Investment Property Considerations

The 令和8年度税制改正大綱 (FY2026 Tax Reform Outline, published December 19, 2025) announced that rental properties acquired within five years of inheritance or gift will be assessed at close to market value, approximately 80% of acquisition price, rather than the traditional 路線価 (rosenka, road-frontage assessed value) basis. While this is a tax rule and does not appear as a line item in the jusetsu itself, it materially affects the economics of investment acquisitions structured around inheritance planning. Buyers in this category should take independent tax advice before contract.

What Foreign Buyers Should Do Before the Session

The jusetsu session is not a formality to be signed through. It is the buyer’s primary statutory opportunity to surface problems before the contract is binding. The following four steps apply specifically to foreign buyers at the ¥300 million and above price point.

First, obtain the document at least 48 hours before the scheduled session. There is no statutory minimum notice period, but a serious broker will provide the document in advance. Read it, or have it read by a bilingual professional, before you sit down with the takken-shi.

Second, confirm the encumbrance position. Every 抵当権 (teitouken, mortgage) and lien on the register must be scheduled for discharge at or before settlement. Ask for written confirmation of the discharge mechanism and timing.

Third, scrutinise the repair reserve fund. Request the most recent 管理組合 (kanri kumiai, building owners’ association) financial statements alongside the jusetsu. A reserve fund deficit in a building of 20 or 30 floors can translate into a special levy of several million yen per unit within a few years of purchase.

Fourth, verify the zoning classification against your intended use. If you plan to redevelop, add a floor, or operate any form of short-term rental, the 用途地域 and 容積率 figures in the jusetsu determine what is legally possible. A broker’s verbal assurance is not a substitute for the registered figures.

For buyers who are also evaluating property type, the Koukyuu guide to types of Japanese houses explains the structural and legal distinctions between detached 一戸建て (ikkodate, standalone residential houses) and manshon units, which affects which jusetsu items are most material to your transaction.

At Koukyuu, every engagement is handled from initial consultation through to contract signing by a licensed 宅建士 (takken-shi), not a sales coordinator who steps aside at closing. For transactions at the ¥300 million floor and above, the jusetsu session is conducted with the buyer’s brief in mind, not the seller’s timeline. The bilingual review of the document is part of the standard engagement, not an add-on.

The 手付金 and What Happens After the Session

Once the jusetsu session is complete and the buyer has acknowledged the disclosure in writing, the sales contract is executed. At that point, the 手付金 (tetsuke-kin, the earnest-money deposit, typically 10% of the purchase price) becomes due. On a ¥500 million acquisition, that is ¥50 million payable at signing.

The tetsuke-kin is not merely a booking fee. Under Japanese contract law, if the buyer withdraws after paying the deposit, the deposit is forfeited. If the seller withdraws, they must return double the deposit amount. The jusetsu must state the deposit amount and the conditions under which each party may rescind. Buyers should read this section carefully and confirm that the cooling-off provisions, if applicable, are correctly stated.

After contract execution, the transaction moves toward the 残代金決済 (zankin-kessai, the final settlement and balance payment), at which point 登記 (touki, transfer of legal title) is recorded at the Legal Affairs Bureau. The full sequence from jusetsu to title transfer typically takes four to eight weeks for resale properties in Tokyo, though new-build completions can extend the timeline considerably.

For buyers who are unfamiliar with how Japanese property is described and measured before reaching the contract stage, the Koukyuu guide to Japanese apartment layouts explains floor-plan notation and the difference between 専有面積 (senyuu menseki, the registered floor area) and the actual usable space, a distinction that regularly surprises buyers accustomed to gross internal area measurements.

The One Thing the Jusetsu Cannot Do

The jusetsu is a disclosure mechanism, not a guarantee. It records what the broker knows and is required to investigate. It does not certify the physical condition of the building beyond what inspections have been commissioned and attached. It does not guarantee the accuracy of the seller’s representations about the property’s history. And it does not replace independent legal, structural, or tax advice.

For a ¥300 million to ¥2 billion Tokyo acquisition, the jusetsu session should be the beginning of due diligence, not the end of it. Structural surveys, review of the building’s 管理規約 (kanri kiyaku, the condominium management rules and bylaws), verification of the repair reserve fund balance, and independent tax analysis are all steps that sit outside the statutory disclosure framework but are essential to a clean transaction.

Foreign buyers who treat the jusetsu as a checkbox to be cleared, rather than a primary source of transaction intelligence, are the ones most likely to surface problems after title has transferred. The document runs to 30 or 40 pages in most Tokyo transactions. Every page warrants attention.
