Rent Seized by Landlord's Creditor in Japan: Can Our Company Set Off Debts and Deposit a Lower Amount?

Imagine your company leases commercial property in Japan. You diligently pay rent to your landlord. However, one day, you receive a formal notice: a creditor of your landlord has legally seized the rent payments your company owes. This means you're now instructed to pay the rent not to your landlord, but to this seizing creditor, or potentially deposit it with a legal affairs bureau. Now, suppose your company also has its own legitimate claims against the landlord – perhaps for a loan you provided them, unreimbursed repair costs, or pre-agreed deductions from a large security deposit. Can your company set off these claims against the seized rent and legally pay or deposit only the reduced amount? This complex issue sits at the intersection of set-off rights and debt execution law in Japan.

Understanding Set-Off (相殺 - Sōsai) under the Japanese Civil Code

Set-off (sōsai) is a fundamental legal mechanism in Japan, allowing two parties who have mutual monetary obligations (or obligations of the same kind) to extinguish these debts up to the amount of the smaller claim. Its purpose is to simplify settlements, provide a form of security for mutual claims, and ensure fairness.

The key conditions for a valid set-off are outlined in Article 505 of the Civil Code:

1. Mutual Debts: Each party must be both a debtor and a creditor to the other.
2. Same Kind of Obligations: Typically, both debts must be monetary or for fungible goods.
3. Active Claim is Due: The claim that the party initiating the set-off wishes to use (their "active claim" or jidō saiken 自動債権) must be due and payable. The claim against which the set-off is being made (the "passive claim" or judō saiken 受動債権, e.g., the rent owed by the tenant) does not necessarily need to be due yet, as the party whose claim it is can effectively waive the benefit of time.
4. Nature of Debts Permits Set-Off: The debts must not be of a nature that prohibits set-off (e.g., certain claims related to torts committed in bad faith or claims for wages necessary for livelihood, though the latter is less relevant in typical commercial rent scenarios).

A set-off is effected by a unilateral declaration from one party to the other (Civil Code Article 506); the other party's consent is not required for the set-off to take legal effect, provided the conditions are met.

The Impact of Seizure on Set-Off Rights: The General Rule (Civil Code Article 511)

When a debt is seized by a creditor (the "seizing creditor"), the rights of the third-party obligor (the party who owes the seized debt, e.g., the tenant) to set off their own claims can be restricted. Civil Code Article 511 is pivotal here. It states that an obligor whose debt has been seized cannot assert a set-off against the seizing creditor using an active claim that the obligor acquired after the seizure of their debt (the passive claim). This rule prevents a third-party obligor from opportunistically acquiring claims after learning of a seizure simply to reduce their payment to the seizing creditor, thereby undermining the effectiveness of the seizure.

Scenario 1: Rent Seized by a General Creditor of the Landlord (via Civil Execution)

This involves a standard creditor of the landlord (not a mortgagee exercising special rights) obtaining a court order to seize the rent owed by the tenant.

• Tenant's Active Claim Acquired Before Rent Seizure:
  A landmark Supreme Court (Grand Bench) judgment on June 24, 1970, provided significant clarity on this issue. The Court held that if the third-party obligor (the tenant) possessed a claim against their creditor (the landlord) before their debt (the rent) was seized, the tenant could generally exercise their right of set-off against the seizing creditor. This right persists even if the formal conditions for set-off (such as both claims being due) were only met after the seizure took place, as long as the claims eventually reached a state suitable for set-off (sōsai tekijō 相殺適状).
  The rationale is to protect the third-party obligor’s pre-existing expectation and reliance on being able to set off their claim. The seizure by the landlord's creditor should not retroactively diminish the tenant's established set-off position regarding claims they already held.
  • Implication: In this situation, the tenant can validly declare a set-off using their qualifying pre-existing claim against the landlord. If an enforcement deposit (shikkō kyotaku) of the rent is then required (for example, if there are multiple competing seizures of the remaining rent amount, or if the tenant opts for a "rights deposit" under Article 156, Paragraph 1 of the Civil Execution Act), the tenant would typically deposit the net amount of rent due after the set-off.
• Tenant's Active Claim Acquired After Rent Seizure:
  Consistent with Civil Code Article 511, if the tenant acquired its claim against the landlord after the rent was seized, set-off against the seizing creditor is generally not permitted. The tenant would be required to pay the full seized rent amount to the seizing creditor (or deposit it as required) and would need to pursue their newly acquired claim against the landlord separately.

Scenario 2: Rent Seized by a Mortgagee of the Leased Property (Exercising Rights over Collateral Proceeds - Butsujō Daii)

Commercial properties are often subject to mortgages. If the landlord defaults on their mortgage obligations, the mortgagee (lender) can, under certain conditions, exercise a right over the proceeds of the mortgaged property (teitōken no butsujō daii 抵当権の物上代位), which includes seizing rent payments directly from tenants. This scenario has specific rules regarding set-off.

• Key Precedent: Supreme Court, Third Petty Bench, March 13, 2001. This crucial judgment established that a tenant cannot assert a set-off against a seizing mortgagee using a claim against the landlord if that claim (the tenant's active claim, e.g., for a loan to the landlord or for repair costs the landlord should have borne) was acquired by the tenant after the mortgage on the leased property was registered with the Legal Affairs Bureau. This rule applies even if the tenant acquired their claim before the mortgagee actually initiated the specific act of seizing the rent, as long as it was after the mortgage registration. The public registration of the mortgage serves as a critical cut-off point, putting subsequent acquirers of claims against the landlord on notice regarding the mortgagee's potential priority over rental income.
• However, if the tenant's active claim against the landlord was acquired before the mortgage was registered, the tenant can generally still assert this pre-existing set-off against the seizing mortgagee.
• Implication: When a mortgagee seizes rent, the tenant's ability to set off is significantly more restricted. The date of mortgage registration, not just the date of rent seizure, becomes paramount. Tenants entering into leases for mortgaged properties, or acquiring claims against their landlords after a mortgage is in place, must be aware of this limitation.

Special Cases: Construction Cooperation Money and Security Deposits

Certain types of financial arrangements common in Japanese commercial leases can also interact with set-off rights and rent seizures:

1. Construction Cooperation Money (Kensetsu Kyōryokukin 建設協力金):
   This often involves a significant upfront payment by a prospective tenant to the landlord, which the landlord uses to help fund the construction or fit-out of the leased premises. The agreement typically provides for this "cooperation money" to be returned to the tenant over time by way of deductions from (or offsets against) future rent payments. This is effectively a pre-agreed amortization or a "set-off reservation" (sōsai no yoyaku).
   The argument often made is that if this agreement for rent offset was established at the inception of the lease (or even a pre-lease agreement), and particularly if this occurred before the property was mortgaged by the landlord (or before a subsequent mortgage was registered), the tenant's right to this pre-agreed rent reduction (set-off) should be assertable against a mortgagee who later seizes the rent. The tenant's significant upfront contribution and reliance on this amortization schedule are strong equitable factors.
2. Security Deposits (Shikikin 敷金 / Hoshōkin 保証金):
   While typically returned at the end of a lease after deducting for damages or unpaid rent, some large commercial leases, particularly those involving substantial security deposits, might include provisions for the periodic return or amortization of portions of the deposit by offsetting them against ongoing rent payments.
   • If such a set-off mechanism regarding the security deposit was agreed upon, and the tenant's claim to this periodic offset (as a form of pre-agreed partial refund) arose before a mortgage on the property was registered, this set-off may be assertable against a seizing mortgagee.
   • Conversely, if the lease containing such an amortizing security deposit set-off was entered into after a mortgage was already registered on the property, the tenant would likely not be able to assert this set-off against the seizing mortgagee. The tenant would be considered to have taken the lease subject to the prior rights established by the mortgage.

Making an Enforcement Deposit After a Valid Set-Off

If, based on the rules outlined above, a tenant has a valid right to set off a claim against the rent owed:

1. The tenant effectively reduces the amount of rent payable for that specific period.
2. If an enforcement deposit is subsequently required (e.g., because there are multiple competing seizures for the remaining net rent, or if the tenant is making a voluntary "rights deposit" under Article 156(1) of the Civil Execution Act perhaps due to one seizure on the net amount), the tenant should deposit the net amount of rent due after the valid set-off has been applied.
3. The deposit application form (kyotakusho) should clearly state the original gross rent amount, the amount of the claim being set off (and a brief basis for it), and the resulting net amount being deposited. This transparency is crucial for the court and other creditors to understand the basis of the deposited sum.

Practical Guidance for Tenants Facing Rent Seizure

If your company is a tenant in Japan and faces a situation where rent payments are seized by a landlord's creditor, and you believe your company has claims against the landlord that could be set off:

• Thoroughly Document Your Claims: Maintain clear and dated records of all claims your company has against the landlord (e.g., loan agreements, invoices for repairs you covered, relevant clauses from the lease regarding security deposit amortization or construction cooperation money). The date your claim arose is critical.
• Review Your Lease and Property Title Information: Understand the terms of your lease. If possible, ascertain (e.g., through a property registration search) if the leased property is subject to a mortgage and, if so, when that mortgage was registered. This is vital for assessing set-off rights against a seizing mortgagee.
• Formal Declaration of Set-Off: When exercising a right of set-off, it is best practice to issue a clear, written declaration of set-off to the landlord. If rent has been seized, consider also notifying the seizing creditor of the set-off exercised, explaining its basis (though the legal effect on the seizing creditor will depend on the rules discussed above).
• Identify the Nature of the Seizing Creditor: Pay attention to the details in the seizure order. As background materials sometimes note, court case numbers for general civil execution seizures in Japan might use a "(ル)" (ru) designator in their case number, while seizures by mortgagees exercising their security rights (like butsujō daii) might sometimes use a "(ケ)" (ke) designator. While not definitive, this can be an initial clue. The seizure order documents themselves should clarify the basis of the creditor's claim.
• Seek Prompt Legal Advice: The rules surrounding set-off against seized claims, especially when differentiating between general creditors and mortgagees, are complex and fact-dependent. Obtaining advice from legal counsel in Japan experienced in civil execution and real estate law is crucial to correctly determine your company's rights and obligations and to decide the appropriate amount to pay or deposit.

Conclusion: A Complex Interplay of Rights and Priorities

A tenant's ability to set off its own claims against rent that has been seized by a landlord's creditor in Japan is not absolute. It is a nuanced area of law where the timing of when the tenant's claim arose, when the rent was seized, and—most critically in the case of seizures by mortgagees—when the mortgage was registered on the property, all play decisive roles.

The general principle, supported by a 1970 Supreme Court ruling, offers reasonable protection for tenants to set off pre-existing claims against seizures by general creditors of the landlord. However, a subsequent 2001 Supreme Court decision significantly curtails this right when the seizing party is a mortgagee whose mortgage predates the tenant's claim. Pre-agreed set-off mechanisms within lease agreements, such as for construction cooperation money or amortizing security deposits, may withstand seizure if they were firmly established before the relevant third-party rights (like a mortgage) came into existence.

Given these complexities, tenants in Japan who find their rent obligations subject to seizure and who believe they have valid grounds for set-off must navigate carefully. A thorough understanding of their claims, the landlord's secured debt status (if any), and the specific nature of the seizing creditor, ideally guided by professional legal advice, is essential to protect their interests and ensure compliance with Japanese law when deciding how much rent to pay or deposit.
