How To Check If A Japanese Property Has A Repurchase Clause

What 買戻特約 (kaimodoshi tokuyaku, a registered repurchase clause) means on a Japanese property’s registration record, why it can let the original seller reclaim the property years later — even from a buyer who purchased it from someone else — and how to check before you buy.

Published: September 4, 2026

When the clean owner's name has a string attached

You order a property registration record, find the current owner's name in 甲区, and it looks clean — no mortgage, nothing underlined. But 甲区 is a running history of every past transfer, not just the latest line: a note attached to an earlier ownership-transfer entry — from a sale years before the current owner even bought in — can mean that earlier seller still has the legal right to force a buy-back at the old price, and that right binds the property no matter who owns it now. That note is 買戻特約 (kaimodoshi tokuyaku, a "repurchase clause" or "repurchase special agreement").

This guide explains what a repurchase clause actually reserves under the Civil Code, why it can bind a buyer who wasn't even party to the original deal, where it shows up on the registration record, and how to check for one before you buy. This is a different entry from a mortgage (抵当権, a lien securing a debt — see How To Check If A Japanese Property Has A Mortgage) and from a provisional registration (仮登記, a placeholder for a right that isn't finalized yet — see How To Check If A Japanese Property Has A Provisional Registration). A repurchase clause is a completed, fully valid right from the moment it's registered — it just sits dormant until someone exercises it. If you have not read a registration record before, start with How To Read A Japanese Property Registration Record.

What a repurchase clause reserves, and why it can bind a later buyer

What a repurchase clause actually reserves

Under the Civil Code (民法), a seller can reserve the right to unwind a sale through a special agreement made at the same time as the sale contract (Civil Code Art. 579). If the seller later exercises that right within the agreed window, the sale is cancelled and the property returns to them — in exchange for returning to the buyer the price originally paid (or, if the parties specifically agreed on a different figure, that agreed amount) plus the buyer's contract costs.

The period is capped by law: a repurchase clause cannot run longer than 10 years, and if the contract sets a longer period, the law shortens it to 10 years automatically. If the parties don't specify a period at all, the cap defaults to 5 years. Once a period is set, it cannot later be extended (Civil Code Art. 580).

Why it can bind a buyer who never dealt with the original seller

This is the detail that catches people off guard. If the repurchase clause is registered at the same time as the sale's ownership-transfer registration, it becomes enforceable against third parties (Civil Code Art. 581) — meaning it is a right that runs with the registered title, not a personal arrangement between the original seller and the original buyer. If that first buyer resells the property to you before the repurchase window closes, the original seller can still exercise the buy-back against you as the current owner, even though you were never part of their original deal.

On the record, this means the clause stays attached to the original sale's transfer entry even after later resales — it does not move to, or repeat on, the current owner's own transfer entry. Reading only the newest 所有権移転 line in 甲区 and stopping there is exactly how a buyer misses a clause that is still fully enforceable against them.

Where it appears on the record

A registered repurchase clause is recorded in 甲区 (the ownership section) as a 付記登記 (fuki touki, a subsidiary entry) attached directly to the 所有権移転 (ownership transfer) entry it was created alongside — not as a separate, independently numbered line the way a mortgage sits in 乙区. The Ministry of Justice's own official sample registration entries for repurchase rights show this same structure: the repurchase clause recorded as an annotation on the transfer entry, naming the repurchase amount, the contract costs, and the repurchase period. If the property has been resold since, that transfer entry is an earlier line in 甲区's history — not the entry naming the current owner — so reading only the newest transfer line is not enough. You have to read every 所有権移転 entry in 甲区, from the earliest to the current owner, along with the subsidiary text attached to each one.

The two situations you'll actually run into

Two patterns account for most active repurchase clauses in practice:

  • Subdivided residential land sold by a municipality or developer. These sellers commonly attach a repurchase clause to force the buyer to build a house within a set period. If the buyer doesn't build in time, the seller can exercise the clause and reclaim the land at the original price — a condition aimed at preventing land banking rather than actual housing.
  • An informal substitute for secured lending. Older or family-related transactions sometimes use a sale-plus-repurchase-clause structure as a stand-in for a mortgage: the "sale price" functions as a loan amount, and the "seller" can recover the property by repaying it within the period, similar in effect to redeeming collateral.

Either way, treat a repurchase clause as an unusual right working against you as the buyer, not as evidence of a defect in the property itself.

The practical risk if the clause is still active

If an unexpired, uncancelled repurchase clause is on the record, the person holding that right could force a buy-back at the original price (or the separately agreed figure) within the remaining window — even from you, even years after you bought from someone else. It also complicates financing: because the clause could cause your ownership to unwind, a lender may hesitate to accept the property as collateral, and if the original holder ever does exercise the right, the property reverts to them and any mortgage you placed on it afterward is extinguished along with your ownership.

That risk is tied specifically to the stated repurchase period. Once that period runs out — the agreed term, or the 5-year default if none was set — the seller's right to exercise the buy-back is extinguished by law (Civil Code Art. 580), whether or not the registration has been formally cancelled yet. An uncancelled entry past its own deadline is a paperwork problem, not a live claim: the registry simply doesn't erase entries automatically just because their period has elapsed. Since April 1, 2023, a Real Property Registration Act amendment (Art. 69-2) lets the current registered owner apply alone — without the original seller's cooperation — to cancel a stale repurchase-clause registration once 10 years have passed from the date of the underlying sale contract, regardless of whether the stated repurchase period itself was shorter, such as 5 years. That route only clears entries old enough to qualify; it does nothing for one still inside its window, where the right is genuinely live.

How to check for a repurchase clause before you buy

Here is a practical way to check before you buy:

  1. Order the registration record and read every ownership-transfer entry in 甲区, from the earliest to the current owner — not just the line naming who owns it now. A repurchase clause is a 付記登記 riding on whichever 所有権移転 entry it was created alongside, which can be an earlier sale in the property's history rather than the transfer to the current owner. Skimming straight to "who owns it now" is exactly how this gets missed.
  2. Identify the entry by its purpose. Look for 買戻特約 (or 登記の目的: 買戻権) in 甲区, and read the attached details: the repurchase amount, the contract costs, and the repurchase period stated in the entry.
  3. Confirm whether it's been cancelled. An underlined entry, or one followed by a 抹消 (cancellation) entry, has already been discharged and no longer matters. An entry without either is still on the record — check its dates next before assuming the right behind it is still exercisable.
  4. Check the dates against the caps. Compare the sale-contract date shown in the entry to today: has the stated repurchase period (or the 5-year default, if none was specified) already lapsed on its own terms? If so, the seller's right to exercise the buy-back is extinguished by law (Civil Code Art. 580), even though the entry itself is still sitting on the record uncancelled — the registry does not erase it automatically. Separately, once more than 10 years have passed since the contract date, the owner's unilateral cancellation route under Art. 69-2 opens up — but only if someone actually files it, which is why a lapsed clause can otherwise sit uncancelled indefinitely.
  5. Ask the agent or seller directly who holds the right, the repurchase amount, and whether it will be cancelled before or at closing. Get this in writing rather than relying on a verbal assurance that "it's old, it doesn't matter" — even a clause whose stated period has clearly lapsed should be formally cancelled before you close, since an uncancelled entry can still complicate a title check or financing even after the underlying right has expired.
  6. If the clause traces back to a subdivided-land sale, ask whether the underlying condition — usually building within a set period — was ever satisfied. An unmet construction condition is precisely the situation the original seller could still act on.
  7. Loop in a judicial scrivener (司法書士) for anything that isn't a clean cancellation before closing. Confirming whether an old-looking repurchase clause has genuinely lapsed, negotiating its removal, or filing an Art. 69-2 unilateral cancellation is worth professional handling rather than a guess based on how old the entry looks.

The most common mistake is treating a clean-looking current owner's name in 甲区 as the whole ownership picture — a repurchase clause is attached to whichever transfer entry it was created alongside, which can be an earlier sale in the property's history rather than the current owner's own entry, so reading only the newest line is exactly how it gets missed. The second is skipping the date check in step 4: an entry's repurchase period can already have lapsed by law even though the registration itself is still sitting there uncancelled, so treating "still on the record" as the same thing as "still exercisable" either overstates a genuinely expired clause or, more dangerously, understates a live one if you never actually check the dates.

What the registry shows, what it doesn't, and pricing

What the registration record can and cannot tell you here:

  • What it shows reliably: whether a repurchase clause is registered, the repurchase amount and contract costs, the repurchase period, and — once filed — whether it has been cancelled. All of this sits in 甲区, attached to the ownership-transfer entry.
  • What it does not show: whether the party holding the right still intends to exercise it, or whether an unmet condition behind it (such as a construction deadline) is even still being tracked informally by the original seller. Those depend on the parties' actual conduct, not on anything the registry records.
  • How to order the record: Order the full registration record — ¥1,500 for land, ¥1,500 for building — which already includes the complete 甲区 ownership history and 乙区 in one document, so a single record covers this check with nothing extra required. If the purchase includes both land and a building, order both records: they are legally separate registrations in Japan, a repurchase clause can exist on only one of them, and you cannot know in advance which one carries it — that's the whole point of checking. Repurchase clauses are considerably more common on land, especially subdivided residential lots sold by a municipality or developer, than on buildings, but checking only the more likely record can still miss one on the other. The Ownership Matters extract (+¥500) is not useful for this check: it lists only the current owner's name and address rather than the ownership history and any subsidiary entries, so it cannot show a repurchase clause even when one exists — order the full record instead.

None of this makes a property with a repurchase clause untouchable — plenty of these clauses trace back to satisfied conditions or long-expired windows that just haven't been formally cancelled yet. The point is to catch it before signing rather than after. Our Japan property due diligence checklist covers where this check fits alongside ownership, mortgages, and boundaries.

FAQ about repurchase clauses (kaimodoshi tokuyaku) in Japan

FAQ

What does 買戻特約 mean? It means "repurchase clause" or "repurchase special agreement" — a right the seller reserves, at the same time as the sale, to cancel the sale and reclaim the property within an agreed period by returning the price paid (or an amount the parties agreed on) plus contract costs.

Can the original seller really force a buy-back from someone who bought the property from someone else? Yes, if the clause was registered at the same time as the ownership-transfer registration. That registration makes the right enforceable against third parties, so it runs with the title rather than staying personal to the original buyer — a later purchaser can be bound by it even though they never dealt with the original seller.

How long can a repurchase clause last? Up to 10 years if a period is specified — a longer stated period is automatically shortened to 10 years by law. If no period is specified, the cap defaults to 5 years, and once a period is set it cannot be extended later.

Can I remove an old repurchase clause myself? If more than 10 years have passed since the date of the underlying sale contract, a Real Property Registration Act amendment in force since April 1, 2023 (Art. 69-2) lets the current registered owner apply alone to cancel the registration, without needing the original seller's cooperation. Inside that 10-year window, cancellation generally still requires the right holder's cooperation or a court judgment.

Is a repurchase clause a red flag? It's a reason to ask questions and confirm the details before you rely on it, not automatically a reason to walk away. Many active-looking entries trace back to a satisfied condition or a lapsed window that simply was never formally cancelled — but "probably lapsed" is not the same as "cancelled on the record," and the difference matters if you're relying on clean title to close or to secure financing.
