Japanese Insolvency Proceedings and Their International Effects: What US Companies Need to Know?

When a Japanese company with international operations, assets located abroad, or foreign creditors enters into domestic insolvency proceedings—such as bankruptcy (破産 - hasan), civil rehabilitation (民事再生 - minji saisei), or corporate reorganization (会社更生 - kaisha kōsei)—a host of complex international issues arise. Understanding how Japanese law addresses these cross-border dimensions is crucial for foreign stakeholders, including U.S. companies that may be creditors, investors, or contractual counterparties. This article examines the key international aspects of domestic Japanese insolvency proceedings, including the jurisdictional reach of Japanese courts, the intended extraterritorial effect of Japanese insolvency orders, the rules governing creditors who recover assets outside Japan, and Japan's framework for cooperating with foreign courts and insolvency representatives in situations involving parallel proceedings.

The Shift from Territoriality in Domestic Japanese Insolvency Law

Japan's approach to the international aspects of its own insolvency proceedings has undergone a significant evolution.

Historical Stance: Strict Territoriality (属地主義 - Zokuchi Shugi)
For many decades, Japanese insolvency law, as exemplified by provisions in the old Bankruptcy Act (e.g., former Article 3), was characterized by a strict principle of territoriality. This generally meant that Japanese insolvency proceedings were considered to have effect only with respect to the debtor's assets located within Japan, and, conversely, foreign insolvency proceedings were not typically recognized as having any direct legal effect on assets in Japan.

Modern Approach: Embracing Modified Universalism and Extraterritorial Intent
The comprehensive insolvency law reforms undertaken in Japan around the year 2000 and 2001, which included significant amendments to the Bankruptcy Act, the Civil Rehabilitation Act, and the Corporate Reorganization Act, marked a fundamental departure from this insular approach. These reforms embraced a more outward-looking perspective, often described as "modified universalism," which acknowledges the global nature of modern commerce and the need for international cooperation in insolvency matters.

• Worldwide Scope of the Insolvency Estate:
  • Under the current Bankruptcy Act (Article 34(1)), the bankruptcy estate (破産財団 - hasan zaidan) is now explicitly defined to comprise all property belonging to the debtor at the time of the commencement of the proceedings, regardless of whether such property is located in Japan or abroad.
  • Similarly, under the Civil Rehabilitation Act (Article 38(1)) and the Corporate Reorganization Act (Article 72(1) for trustees, implicitly for DIPs under their general management powers), the authority of the debtor-in-possession (DIP) or the appointed trustee to manage and dispose of the debtor's property is intended to extend to all of the debtor's property, wherever situated, including assets located in foreign countries. (Note: Art. 32(1) of the Corporate Reorganization Act relates to the provisional administrator; Art. 72(1) establishes the trustee's broad powers).
• Practical Realization Depends on Foreign Recognition: It is crucial to understand that while Japanese law asserts this worldwide scope for its insolvency estates and the authority of its appointed insolvency practitioners, the practical ability of a Japanese trustee or DIP to actually exercise control over, or recover, assets located in a foreign jurisdiction depends heavily on the laws of that foreign jurisdiction and whether its courts will recognize and give effect to the Japanese insolvency proceeding. This is where international treaties or domestic laws in other countries based on principles of comity or on models like the UNCITRAL Model Law on Cross-Border Insolvency (which Japan itself has adopted for incoming foreign proceedings via its Recognition and Assistance Act) become critically important.

International Insolvency Jurisdiction of Japanese Courts (国際倒産管轄 - Kokusai Tōsan Kankatsu)

A key element of the modern framework is the establishment of clear statutory rules determining when Japanese courts have international jurisdiction to open main (or primary) insolvency proceedings against a debtor with international connections. Prior to the reforms, these rules were less explicit and often inferred from domestic venue provisions, which was not always satisfactory for international cases. The current laws provide specific jurisdictional gateways:

• For Bankruptcy (破産 - Hasan) and Civil Rehabilitation (民事再生 - Minji Saisei) Proceedings (Bankruptcy Act, Art. 4; Civil Rehabilitation Act, Art. 4):
  • If the debtor is an individual, Japanese courts have jurisdiction if the individual has their business office (営業所 - eigyōsho), domicile (住所 - jūsho), residence (居所 - kyosho), or any property located in Japan.
  • If the debtor is a corporation or other legal entity/association, Japanese courts have jurisdiction if the entity has its business office (営業所 - eigyōsho), administrative office (事務所 - jimusho), or any property located in Japan.
    The inclusion of the "presence of any property" as a sufficient basis for asserting main insolvency jurisdiction is relatively broad. It is intended, in part, to protect domestic Japanese creditors who may have extended credit relying on the existence of assets within Japan.
• For Corporate Reorganization (会社更生 - Kaisha Kōsei) Proceedings (Corporate Reorganization Act, Art. 4):
  The jurisdictional threshold for commencing Corporate Reorganization proceedings is somewhat more stringent. The debtor company must have a business office (営業所 - eigyōsho) located in Japan. The mere presence of assets in Japan, without an operational business office, is generally not sufficient to found jurisdiction for these more intensive and complex reorganization proceedings. This reflects the nature of Corporate Reorganization, which deeply impacts the company's governance, secured creditor rights, and often involves significant operational restructuring, thus warranting a stronger connecting factor to Japan than simply having isolated assets in the country.
• Principle of Equal Treatment for Foreigners (内外人平等の原則 - Naigaijin Byōdō no Gensoku):
  It is also important to note that modern Japanese insolvency laws explicitly uphold the principle of equal treatment for foreign nationals and foreign corporations. Foreign individuals and entities generally have the same legal standing as their Japanese counterparts to be debtors in Japanese insolvency proceedings, or to participate as creditors in such proceedings (Bankruptcy Act, Art. 3; Civil Rehabilitation Act, Art. 3; Corporate Reorganization Act, Art. 3). This marked a departure from older rules that sometimes imposed conditions of reciprocity.

The "Hotchpot" Rule: Ensuring Creditor Equality in Global Recoveries (ホットチョップ・ルール - Hotchopotto Rūru)

When a Japanese company with assets in multiple countries enters insolvency proceedings in Japan, there is a risk that some creditors, particularly those with a strong international presence or knowledge of foreign legal systems, might seek to recover their claims by seizing the debtor's assets located outside Japan through separate enforcement actions in those foreign jurisdictions. If such actions are successful, these creditors could potentially recover a larger proportion of their claims than other creditors who rely solely on distributions from the Japanese insolvency estate.

To counteract this potential for unequal treatment and to promote the principle of creditor equality on a global scale, Japanese insolvency laws incorporate a version of the "hotchpot" rule (sometimes referred to as a "claw-back" or equalization principle in other legal systems). This rule is found in the Bankruptcy Act (Art. 201(4)), the Civil Rehabilitation Act (Art. 89(2)), and the Corporate Reorganization Act (Art. 137(2)).

• How the Hotchpot Rule Works:
  If a creditor, after the formal commencement of the Japanese insolvency proceedings, receives a payment or recovers value by exercising rights against the debtor's property located outside Japan, that creditor is generally not entitled to receive any distributions from the main Japanese insolvency proceeding until other creditors of the same class or rank have received distributions from the Japanese estate that are proportionately equivalent to what the first creditor recovered from the foreign assets.
• Illustrative Example: Suppose a creditor has a JPY 100 million claim against a company in Japanese bankruptcy. After the Japanese bankruptcy proceedings commence, this creditor manages to seize and recover JPY 30 million (30% of their claim) from the debtor's assets located in Country X. If the general distribution rate to unsecured creditors from the Japanese bankruptcy estate is expected to be, say, only 20%, then this creditor will not receive any further distribution from the Japanese estate on their remaining JPY 70 million claim (their original JPY 100m less the JPY 30m recovered abroad). If the Japanese distribution rate was, for example, 40%, the creditor would only be entitled to receive a further 10% on their original JPY 100 million claim from the Japanese estate (i.e., JPY 10 million), to bring their total global recovery up to the 40% level enjoyed by other creditors from the Japanese estate. The rule prevents them from unfairly "double-dipping" or exceeding the general recovery rate.
• Filing of Full Original Claim: Despite any foreign recoveries, the creditor is generally entitled to file a proof of claim in the Japanese proceeding for the full original amount of their debt as it existed at the time of commencement (before deducting the subsequent foreign recovery). This establishes their baseline entitlement for calculation purposes (Bankruptcy Act, Art. 109; Civil Rehabilitation Act, Art. 89(1); Corporate Reorganization Act, Art. 137(1)).
• Limitation on Voting Rights: However, for the purpose of voting on a rehabilitation or reorganization plan, the creditor's voting right is typically based on the amount of their claim after deducting the value of any payment or recovery they have already received from foreign assets (Bankruptcy Act, Art. 142(2); Civil Rehabilitation Act, Art. 89(3); Corporate Reorganization Act, Art. 137(3)).
• Rationale: The hotchpot rule is designed to promote equality among creditors of the same class on a worldwide basis, discouraging a "race to the courthouse" in multiple jurisdictions and reinforcing the collective and orderly nature of the main Japanese insolvency proceeding. It is important to note that current Japanese law achieves this equalization primarily through adjusting distributions from the Japanese estate; it does not generally have an explicit "disgorgement" rule that would actively require a creditor who has recovered more than their ultimate pro-rata share from foreign assets to pay back the excess into the Japanese estate (though complex issues of unjust enrichment might arise in extreme cases).

Cooperation with Foreign Insolvency Proceedings and Representatives (並行倒産の際の協力 - Heikō Tōsan no Sai no Kyōryoku)

Modern Japanese insolvency law explicitly recognizes that a single debtor may become subject to insolvency proceedings in Japan and simultaneously in one or more foreign jurisdictions. These are known as "parallel proceedings" (並行倒産 - heikō tōsan). To manage the complexities and potential conflicts arising from such situations, the main Japanese insolvency statutes (Bankruptcy Act, Civil Rehabilitation Act, and Corporate Reorganization Act) now contain dedicated chapters and provisions designed to foster international cooperation and coordination between the Japanese proceeding and any concurrent foreign proceedings.

Key cooperative measures include:

• A. Duty and Power of Japanese Insolvency Practitioners to Cooperate with Foreign Representatives (Bankruptcy Act, Art. 245; Civil Rehabilitation Act, Art. 207; Corporate Reorganization Act, Art. 242):
  • The Japanese bankruptcy trustee (or the debtor-in-possession (DIP) or its supervisor in a Civil Rehabilitation, or the reorganization trustee in a Corporate Reorganization) is statutorily empowered to request necessary information and cooperation from a foreign representative (e.g., a foreign trustee, liquidator, or administrator) who is conducting a foreign insolvency proceeding concerning the same debtor.
  • Conversely, and significantly, the Japanese insolvency practitioner is also placed under a duty to endeavor to provide necessary information and cooperation to the foreign representative for the purpose of facilitating the proper and efficient conduct of the foreign proceeding. This establishes a clear legal basis for two-way communication and mutual assistance between Japanese and foreign insolvency administrations.
• B. Presumption of Grounds for Commencing Domestic Japanese Proceedings Based on an Existing Foreign Proceeding (Bankruptcy Act, Art. 17; Civil Rehabilitation Act, Art. 208; Corporate Reorganization Act, Art. 243):
  • If a foreign insolvency proceeding has already been formally commenced against a particular debtor in another country, this fact creates a rebuttable legal presumption that grounds for commencing a corresponding domestic Japanese insolvency proceeding (e.g., inability to pay debts) also exist with respect to that debtor in Japan.
  • This provision simplifies the process for a foreign representative, or for domestic creditors, to initiate a parallel Japanese insolvency proceeding if it is deemed necessary (for example, to administer assets located in Japan, to deal with local Japanese creditors, or to seek specific relief available under Japanese law). It avoids the need for them to fully re-prove the debtor's underlying insolvency from scratch before the Japanese court.
• C. Specific Rights Granted to Foreign Representatives in Domestic Japanese Proceedings (Bankruptcy Act, Art. 246; Civil Rehabilitation Act, Art. 209; Corporate Reorganization Act, Art. 244):
  Even if a foreign representative has not sought or obtained formal recognition of their foreign proceeding in Japan under the separate Recognition and Assistance Act, they are still granted certain specific rights to participate in a domestic Japanese insolvency proceeding that concerns the same debtor. These typically include:
  • The right to file a petition with the Japanese court for the commencement of Japanese bankruptcy, civil rehabilitation, or corporate reorganization proceedings against the debtor.
  • The right to attend creditors' meetings (or general stakeholder meetings in Corporate Reorganization) held in the Japanese proceeding and to state their opinions.
  • In Civil Rehabilitation and Corporate Reorganization proceedings, the right to propose a rehabilitation or reorganization plan for the debtor.
  • To facilitate these participation rights, the foreign representative is entitled to receive formal notices of key procedural steps and developments in the Japanese proceeding.
• D. Mutual Participation in Proceedings ("Cross-Filing" of Claims by Insolvency Practitioners) (Bankruptcy Act, Art. 247; Civil Rehabilitation Act, Art. 210; Corporate Reorganization Act, Art. 245):
  • This is a particularly noteworthy and progressive feature of Japan's cross-border insolvency framework. It provides a mechanism for insolvency practitioners to act on behalf of creditors in each other's jurisdictions.
  • A Japanese bankruptcy trustee (or DIP/supervisor in Civil Rehabilitation, or reorganization trustee in Corporate Reorganization) is authorized, with the permission of the Japanese court, to participate in a foreign insolvency proceeding concerning the same debtor on behalf of those creditors whose claims have been duly filed and allowed in the Japanese proceeding. For example, the Japanese trustee could file proofs of claim for Japanese creditors in the foreign proceeding.
  • Symmetrically, a foreign representative conducting a foreign insolvency proceeding is authorized, with the permission of the Japanese court, to participate in the Japanese domestic insolvency proceeding on behalf of those creditors whose claims have been primarily recognized or dealt with in that foreign proceeding. For instance, the foreign representative could file proofs of claim for foreign creditors in the Japanese proceeding.
  • This system of "cross-filing" by official insolvency practitioners aims to simplify the complexities of international claim filing for individual creditors, especially smaller creditors who may lack the resources or expertise to navigate multiple foreign legal systems and languages independently. It promotes more comprehensive creditor participation on a global scale and helps to ensure that distributions from all available assets worldwide are made more equitably. This provision is considered to be at the forefront of international insolvency cooperation.

The Interplay with Japan's Recognition and Assistance Act

It is important to see these provisions within Japan's domestic insolvency laws as complementary to Japan's Act on Recognition and Assistance for Foreign Insolvency Proceedings (RAA), which was discussed in a previous article.

• A foreign representative might primarily use the RAA to seek formal recognition of their foreign proceeding by the Tokyo District Court and to obtain specific types of judicial assistance in Japan (such as a stay on local litigation or an order for the turnover of local assets).
• If, in addition to the foreign proceeding, a full domestic Japanese insolvency proceeding is also initiated against the same debtor (either before or after the RAA recognition), then the cooperation provisions embedded within the relevant domestic Japanese insolvency statute (Bankruptcy Act, Civil Rehabilitation Act, or Corporate Reorganization Act) will govern the direct interaction and mutual assistance between the Japanese insolvency practitioner (trustee or DIP) and the foreign representative, and between the Japanese court overseeing the domestic proceeding and the foreign court.
• As outlined in the discussion of the RAA, that Act contains specific rules for coordinating which proceeding should take precedence if a domestic Japanese proceeding and a recognized foreign proceeding are running concurrently. While domestic proceedings are often given priority, there is a significant exception allowing a recognized foreign main proceeding (one in the debtor's COMI) to take precedence under certain conditions that promote international comity and the general interests of creditors globally.

Conclusion

Japan's domestic insolvency laws have made a decisive shift from a historically territorial approach to one that acknowledges the global realities of modern business and finance. By asserting an intended worldwide scope for Japanese insolvency estates, implementing the "hotchpot" rule to foster equality in global creditor recoveries, and embedding robust statutory frameworks for direct cooperation and mutual assistance between Japanese insolvency officials and their foreign counterparts (including innovative provisions for representative cross-filing of claims), Japanese law strives to achieve more coherent, efficient, and equitable outcomes in the increasingly common and complex scenarios of cross-border corporate distress. For U.S. companies and their legal advisors, understanding these outward-looking aspects of Japanese insolvency law is just as vital as understanding how Japan recognizes and provides assistance to incoming foreign proceedings. This knowledge is essential when dealing with Japanese business entities that have an international operational or asset footprint, or when involved as creditors or other stakeholders in a Japanese insolvency proceeding that has international ramifications.
