Enforcing Judgments in Japan: Valuing Claims in Execution-Related Lawsuits

Obtaining a favorable judgment or arbitral award is a significant milestone, but it often marks the beginning of another crucial phase: enforcement. In Japan, the process of executing judgments and other "titles of obligation" (saimu meigi) is governed by a detailed legal framework, primarily the Civil Execution Act (民事執行法 - Minji Shikkō Hō). Within this framework, various types of lawsuits can arise, initiated by creditors, debtors, or even third parties, concerning the validity of the title, the propriety of enforcement procedures, or rights to the assets being seized. Understanding how the "Sogaku" (訴額) – the value of the claim – is determined for these specialized execution-related lawsuits is essential for navigating the enforcement landscape, anticipating costs, and strategizing effectively, particularly for businesses seeking to enforce domestic or foreign judgments.

Overview of Execution-Related Litigation in Japan

Before delving into "Sogaku" valuation, it's helpful to understand the context. Enforcement in Japan typically requires:

1. A Title of Obligation (Saimu Meigi): This is the formal document evidencing the enforceable right, such as a final and binding court judgment, a settlement recorded by a court, a notarized deed containing an execution clause, or a recognized foreign judgment/arbitral award for which an execution judgment has been granted.
2. A Writ of Execution (Shikkōbun): Generally, a writ issued by a court clerk (or a notary for certain notarized deeds) is necessary to commence compulsory execution. This writ certifies the enforceability of the title against a specific debtor for a specific claim.

Disputes can emerge at various points: regarding the conditions for issuing a writ, the underlying enforceability of the title itself, or the rights of third parties to assets targeted for execution. These disputes are resolved through specific types of lawsuits, each with its own "Sogaku" considerations.

1. Action Seeking an Execution Judgment for Foreign Judgments or Arbitral Awards (執行判決を求める訴え - Shikkō Hanketsu o Motomeru Uttae)

For businesses holding a judgment from a foreign court or a significant foreign (and sometimes domestic) arbitral award, enforcing it in Japan typically requires obtaining an "execution judgment" from a Japanese court. This procedure is outlined in Article 24 of the Civil Execution Act for foreign court judgments and relevant provisions of the Arbitration Act (仲裁法 - Chūsaihō, Act No. 138 of 2003, e.g., Article 46) for arbitral awards. The Japanese court does not re-litigate the merits of the original case but examines whether the foreign judgment or award meets the conditions for recognition and enforcement under Japanese law (e.g., reciprocity, public policy, due process for foreign judgments).

"Sogaku" Valuation – A Nuanced Approach:

The valuation of "Sogaku" for an action seeking an execution judgment has been a subject of some discussion. A compelling line of reasoning, reflected in detailed legal commentaries, suggests that the "Sogaku" should be one-half (1/2) of the value of the claim as recognized in the foreign judgment or arbitral award.

• Rationale: This approach views the action for an execution judgment not as an attempt to re-establish the underlying substantive claim (which has already been adjudicated abroad), but rather as a procedural step to obtain the Japanese legal system's imprimatur for domestic enforcement. The core benefit sought is "executability" within Japan. This is seen as analogous to seeking a writ of execution for an already existing domestic title, where the full value of the underlying claim is not re-litigated. To calculate this:
  1. First, the value of the underlying claim granted by the foreign judgment/award is determined according to standard Japanese "Sogaku" rules (e.g., for a monetary award, its JPY equivalent; for an order to deliver specific goods, generally one-half of the goods' market value if the claim is based on ownership).
  2. Then, this determined value is halved to arrive at the "Sogaku" for the execution judgment action itself.
• Example: If a U.S. judgment orders a defendant to pay USD 1,000,000, and its JPY equivalent is 150,000,000 JPY, the "Sogaku" for the action seeking a Japanese execution judgment would be 75,000,000 JPY (1/2 of 150,000,000 JPY).
• Non-Property Rights in Foreign Judgments: If a foreign judgment concerns non-property rights (e.g., certain status-related orders that might require domestic registration or recognition for procedural effects, and for which an execution judgment might exceptionally be deemed necessary), the "Sogaku" would typically be the standard deemed value for non-property claims in Japan, i.e., 950,000 yen.

This "half-value" approach contrasts with potentially simpler views that might have taken the full value of the foreign claim, but it better reflects the limited scope of inquiry in execution judgment proceedings.

2. Action for Grant of a Writ of Execution (執行文付与の訴え - Shikkōbun Fuyo no Uttae)

Normally, a writ of execution is issued by a court clerk upon application by the creditor. However, if the enforceability of the title of obligation depends on the fulfillment of a condition that is not proven by simple documentation, or if execution is sought by or against a successor to the original parties and this succession is not self-evident from public records, the creditor must file a lawsuit to obtain the writ of execution (Article 33, Civil Execution Act).

"Sogaku" Valuation:

Consistent with the logic applied to execution judgments for foreign awards, the "Sogaku" for an action to obtain a writ of execution for a domestic title is generally considered to be one-half (1/2) of the value of the claim stated in that title of obligation. The lawsuit is about unlocking the enforceability of an already established claim, not re-adjudicating the claim itself.

3. Action to Oppose the Grant of a Writ of Execution (執行文付与に対する異議の訴え - Shikkōbun Fuyo ni Taisuru Igi no Uttae)

This action, provided for in Article 34 of the Civil Execution Act, allows the debtor or an interested third party to challenge the propriety of a writ of execution that has already been granted. The grounds for objection typically relate to alleged defects in the issuance of the writ (e.g., that the necessary conditions were not actually met, or that it was issued against the wrong party).

"Sogaku" Valuation:

As the "negative" counterpart to the action for the grant of a writ, the economic interest involved is the prevention of enforcement based on an allegedly improper writ. The "Sogaku" is valued symmetrically: one-half (1/2) of the value of the claim stated in the title of obligation for which the contested writ was issued.

4. Action to Oppose Execution (Claim Objection Suit) (請求異議の訴え - Seikyū Igi no Uttae)

This is a crucial remedy for a debtor under Article 35 of the Civil Execution Act. It allows the debtor to argue that the enforceability of a title of obligation should be precluded due to substantive reasons that arose after the title became final and binding (e.g., the debt has since been paid, discharged by set-off or release, or a condition for its enforcement has not occurred).

"Sogaku" Valuation – Dependent on the Scope of the Objection:

• Seeking to Preclude All Enforceability of the Title: If the debtor contends that the entire underlying obligation reflected in the title has been extinguished or is otherwise wholly unenforceable for supervening reasons.
  • "Sogaku" = The full value of the claim as stated in the title of obligation. For instance, if the title is a judgment for 20,000,000 yen, and the debtor claims full payment, the "Sogaku" of their objection suit is 20,000,000 yen. If the title concerns a non-monetary claim (e.g., delivery of property based on ownership, originally valued at half the property's worth), that original "Sogaku" of the non-monetary claim is used.
• Seeking to Preclude Specific, Individual Execution Measures: Sometimes, a debtor might not dispute the entire debt's existence but objects to the seizure of a particular asset (e.g., claiming it is legally exempt from execution, or that its value is grossly disproportionate to a small remaining debt). While the primary route for such issues might be other procedural objections, a claim objection suit focused on precluding execution against a specific asset is sometimes practically allowed.
  • In such cases, the "Sogaku" = The value of the specific object or asset being targeted by the contested execution measure. This can often be significantly lower than the full value of the claim in the title.
• Seeking a Temporary Stay of Execution Based on Supervening Events: If the debtor alleges a temporary reason why execution should not proceed (e.g., the creditor granted a formal grace period for payment after the judgment became final).
  • "Sogaku" = The economic benefit of the requested delay. This is often calculated as the statutory interest on the value of the claim (as per the title) for the duration of the asserted stay period. However, this calculated interest amount is capped by the actual amount the creditor is attempting to recover through the specific execution proceedings being challenged.
• For Titles Concerning Repetitive or Continuous Claims: If the title of obligation is for ongoing payments (e.g., alimony, periodic damages), and the debtor claims that the underlying obligation for future payments has ceased or did not arise (e.g., due to remarriage of recipient in an alimony case).
  • The "Sogaku" = The sum of any accrued unpaid installments being disputed + the value of future installments projected for a standardized period (typically 12 months, by analogy to how such claims are valued when initially brought). This mirrors the valuation for bringing an initial action for such repetitive claims.

5. Third-Party Action to Oppose Execution (第三者異議の訴え - Daisansha Igi no Uttae)

This action, under Article 38 of the Civil Execution Act, is available to a third party (i.e., someone other than the judgment creditor or debtor) who claims ownership of, or another right that would prevent the sale or delivery of, a specific asset that has been seized in execution proceedings against the debtor.

"Sogaku" Valuation:

The third party's economic interest is the protection of their specific right in the seized asset from wrongful execution. The "Sogaku" is therefore based on this interest, but with an important cap:

• Value Based on the Third Party's Right in the Seized Asset:
  • If the third party claims ownership, superficies, or a leasehold right over the seized asset: The "Sogaku" is typically one-half (1/2) of the value of the seized asset.
  • If the third party claims a possessory right over the seized asset: The "Sogaku" is typically one-third (1/3) of the value of the seized asset.
  • If the seized asset is itself a monetary claim (e.g., a bank account garnished) or a security (e.g., shares seized): The "Sogaku" is generally the amount of the seized monetary claim or the value of the seized security.
• Capped by the Creditor's Execution Claim Amount: Crucially, in all these scenarios, the "Sogaku" for the third-party objection suit cannot exceed the amount of the creditor's claim that is actually being enforced through that specific execution procedure against that asset. The third party's benefit is limited to preventing the seizure or sale of their asset for that particular debt of the judgment debtor; they don't gain more than the value of the threat being averted.

6. Action to Oppose a Distribution Plan (配当異議の訴え - Haitō Igi no Uttae)

After assets are seized and sold in execution, the proceeds are distributed among creditors according to a distribution plan prepared by the court. If a creditor or the debtor disagrees with this plan, they can file an action to oppose it (Articles 90, 166, 170 of the Civil Execution Act).

"Sogaku" Valuation:

• If the Plaintiff is a Creditor: The "Sogaku" is the amount of the increase in the distribution that the plaintiff creditor would receive if their objection to the plan is upheld. Calculating this can be complex, as it may involve reallocating funds also claimed by other creditors.
• If the Plaintiff is the Debtor (or the owner of the property, if it was sold to satisfy a debt not their own, e.g., collateral provided by a third party): The "Sogaku" is the amount of the specific distribution being objected to. For example, if the debtor argues that a creditor included in the distribution plan actually has no valid claim or a smaller claim, the "Sogaku" is the portion of the distribution allocated to that contested part of the creditor's claim. Even if a successful objection doesn't result in a larger surplus for the debtor directly, reducing an invalid claim against the proceeds benefits the debtor's overall financial position or the integrity of the distribution.

7. Other Specialized Execution-Related Actions (Briefly)

Japan's legal framework also includes other specialized actions related to insolvency and reorganization proceedings, which have their own "Sogaku" rules often defined by those specific statutes:

• Action to Determine a Bankruptcy Claim (破産債権確定の訴え - Hasan Saiken Kakutei no Uttae): Under Article 252 of the Bankruptcy Act, the "Sogaku" is determined by the court based on the estimated amount of distribution (dividend) the claim is likely to receive. For practical purposes at the time of filing, when the actual distribution rate is often unknown, legal commentaries suggest that a common provisional approach is to use one-tenth (1/10) of the nominal amount of the disputed bankruptcy claim as the "Sogaku."
• Avoidance Actions in Bankruptcy (否認権行使の訴え - Hininken Kōshi no Uttae): When a bankruptcy trustee seeks to avoid (claw back) preferential or fraudulent transfers made by the debtor before bankruptcy, the "Sogaku" of this avoidance action is the value of the property or transaction being avoided or recovered for the benefit of the bankruptcy estate. This is analogous to a fraudulent conveyance action.
• Action to Determine Reorganization Claims or Secured Reorganization Claims (更生債権・更生担保権確定の訴え - Kōsei Saiken / Kōsei Tanpoken Kakutei no Uttae): In corporate reorganization proceedings, Article 156 of the Corporate Reorganization Act states that the "Sogaku" for an action to determine such claims is to be fixed by the reorganization court itself, based on the estimated benefit the claimant is likely to receive under the reorganization plan. The court hearing the determination suit does not independently set this "Sogaku" but is guided by the reorganization court's specific order. (Practices in major courts like the Tokyo District Court have established internal guidelines for the reorganization court's determination, e.g., often using a fraction like 1/3 of an unsecured claim amount or 2/3 of the value of security for a secured claim as a starting point for this judicial determination).

Conclusion: Navigating the Complexities of Enforcement Valuation

The valuation of "Sogaku" in execution-related lawsuits in Japan is a highly specialized field, with rules tailored to the specific purpose and nature of each type of action. It is distinct from the "Sogaku" of the original underlying claim that led to the judgment or title of obligation. Common themes include valuing the "executability" itself (often at half the underlying claim's value, as seen in actions for execution judgments or writs of execution), the value of specific assets when challenging individual enforcement measures or asserting third-party rights (often capped by the creditor's claim), or the direct financial impact of an objection (as in distribution disputes).

For businesses, particularly those involved in cross-border commerce and seeking to enforce foreign judgments or arbitral awards in Japan, or those needing to protect their assets from execution or navigate insolvency-related claim disputes, a clear understanding of these nuanced valuation rules is crucial. It directly impacts the costs associated with these necessary post-judgment proceedings and informs strategic decisions. Given the technical nature of execution law and the specific "Sogaku" principles applicable to each distinct type of enforcement-related lawsuit, seeking advice from Japanese legal counsel with expertise in civil execution and enforcement matters is highly recommended for accurate assessment and effective action.
