6.6 Commercial transactions

Overview of commercial law

Commercial law in Japan governs business transactions and relationships between entities. It blends civil law traditions (inherited largely from German and French models) with modern commercial practices developed through Japan's postwar economic growth. The goal is to facilitate economic activity while maintaining fairness and stability across stakeholders.

Key principles of transactions

Four principles form the foundation of Japanese commercial transactions:

• Good faith and fair dealing (shingi seijitsu no gensoku) underpins all commercial dealings, requiring parties to act honestly and reasonably throughout the relationship.
• Freedom of contract (keiyaku jiyū no gensoku) allows parties to set their own terms, subject to legal restrictions and public policy limits.
• Consensualism means contracts can be formed by mutual agreement alone, with less emphasis on written formalities than in many Western legal systems.
• Duty of care (chūi gimu) requires parties to exercise reasonable care when fulfilling contractual obligations.

Types of commercial entities

Japan recognizes four main types of commercial entities under the Companies Act:

• Kabushiki Kaisha (KK) is the standard corporation, offering limited liability to shareholders. It's the go-to structure for large-scale businesses and publicly traded companies.
• Godo Kaisha (GK) is a more flexible structure similar to an LLC, popular among small and medium-sized enterprises. Members enjoy limited liability with fewer governance requirements than a KK.
• Gomei Kaisha is a general partnership where all partners bear unlimited liability. It's uncommon today but still used in some traditional businesses.
• Goshi Kaisha is a limited partnership that combines general partners (unlimited liability) with limited partners (liability capped at their contribution).

Contract formation

Contract formation under Japanese commercial law follows a structured process emphasizing mutual agreement and clear communication. The Japanese Civil Code and Commercial Code provide the legal framework, supplemented by industry-specific regulations and established trade customs.

Offer and acceptance

• An offer (mōshikomi) must be sufficiently definite and show the offeror's intention to be bound if the other party accepts.
• Acceptance (shōdaku) must be unconditional and match the offer's terms exactly. A response that changes the terms counts as a counter-offer, not acceptance.
• Japan follows the arrival rule (tōtatsu shugi) under the Civil Code as revised in 2020: acceptance becomes effective when it reaches the offeror, not when it's dispatched. This differs from the older "dispatch rule" that previously applied.
• Irrevocable offers (kakutei mōshikomi) bind the offeror for a reasonable period. Other offers can generally be revoked before acceptance arrives.

Consideration and capacity

A major difference from common law systems: consideration is not required in Japanese contract law. There's no need for each party to provide something of value for the contract to be enforceable. Instead, the contract simply needs a lawful purpose and mutual consent.

• Legal capacity (nōryoku) determines who can enter binding contracts. Minors (miseinen, under 18) and adults under guardianship (seinen kōken) have limited capacity, and contracts made by these individuals can be rescinded under specific rules set out in the Civil Code.

Performance and breach

Japanese courts generally prefer specific performance over monetary damages when a contract is breached. This reflects a broader preference for maintaining business relationships rather than simply compensating losses with money.

Contractual obligations

• Primary obligations (shutaru gimu) are the core duties explicitly stated in the contract.
• Ancillary obligations (fuzui gimu) are implied duties like providing necessary information or cooperating in good faith, even if not written into the agreement.
• Force majeure (fuka kōryoku jijō) may excuse performance when circumstances are both unforeseeable and unavoidable (natural disasters, for example).
• The duty to mitigate (songai keigen gimu) requires the non-breaching party to take reasonable steps to minimize their losses after a breach occurs.

Remedies for breach

Remedies available to the non-breaching party include:

• Specific performance (genjō hōfuku) compels the breaching party to fulfill their original obligations. Courts favor this remedy when performance is still possible.
• Damages (songai baishō) compensate for losses caused by the breach:
  • Expectation damages (kitai rieki no baishō) aim to put the injured party in the position they'd have been in had the contract been performed.
  • Reliance damages (shinrai rieki no baishō) cover losses incurred because the party relied on the contract.
• Termination (kaijo) lets the non-breaching party end the contract in cases of material breach. Under the 2020 Civil Code reforms, termination no longer requires fault on the breaching party's side; it focuses on whether the breach is sufficiently serious.
• Liquidated damages clauses (yaku'atsu baishōkin jōkō) set predetermined amounts payable upon breach. Courts can review these for reasonableness and may reduce excessive amounts.

Sale of goods

The sale of goods is primarily governed by the Civil Code and the Commercial Code. For international sales involving Japanese parties, the United Nations Convention on Contracts for the International Sale of Goods (CISG) applies unless the parties expressly exclude it.

Transfer of ownership

• Ownership transfer (shoyūken no iten) occurs at the time of the parties' agreement under the Civil Code's default rule, though commercial practice often ties it to delivery.
• Risk of loss (kiken futan) typically passes to the buyer upon delivery but can be modified by contract terms or Incoterms.
• Retention of title clauses (shoyūken ryūho jōkō) let sellers keep ownership until full payment is received, providing security in credit sales.
• Delivery (hikiwatashi) can be actual or constructive, with several recognized methods: direct handover, delivery to a carrier, or delivery of documents of title.

Warranties and conditions

• Express warranties (meiji no hosho) are explicitly stated guarantees about the goods' quality or characteristics.
• Implied warranties (mokuteki no hosho) arise by operation of law. The warranty of merchantability (shōhin sei no hosho) is a key example, requiring goods to meet a basic standard of quality.
• Conditions (jōken) are essential contract terms. Breach of a condition may entitle the innocent party to terminate the contract entirely.
• The warranty against defects (kashi tanpo, now reformed under the 2020 Civil Code as "non-conformity with contract") requires the seller to deliver goods that conform to the contract. Buyers who receive non-conforming goods can request repair, replacement, price reduction, or damages.

Secured transactions

Secured transactions give creditors security interests in debtors' assets, reducing lending risk and promoting access to credit. The system balances the interests of creditors, debtors, and third parties.

Types of security interests

• Mortgage (teitō ken) applies primarily to real property and requires registration for perfection. It's the most common form of security for real estate-backed lending.
• Pledge (shichi ken) involves transferring possession of the collateral to the creditor. It's commonly used for tangible movables and securities.
• Assignment of receivables (saiken jōto) allows accounts receivable to serve as collateral, with specific rules for perfection and priority (registration or notice to the obligor).
• Retention of title (shoyūken ryūho) provides security for sellers in credit sales by allowing them to reclaim goods if the buyer defaults.

Priority and perfection

Perfection (taiko yōken) makes a security interest enforceable against third parties, typically through registration or transfer of possession.

Priority among competing security interests follows these general rules:

• The first-to-file-or-perfect rule generally applies, meaning earlier registration or perfection wins.
• Statutory liens (hōtei tanpo ken) may take priority over consensual security interests in certain cases (e.g., tax liens).
• The public notice system (kōshi seido) provides information about existing security interests through registries, allowing parties to check for prior claims.
• For cross-border transactions, conflict of laws rules determine the applicable law, typically based on the location of the collateral.

Negotiable instruments

Negotiable instruments facilitate the transfer of monetary rights in commercial transactions. The Bills of Exchange and Promissory Notes Act (Tegata hō) and the Checks Act (Kogitte hō) provide the primary legal framework.

Promissory notes vs bills of exchange

Promissory notes (yakusoku tegata) contain an unconditional promise by the maker to pay a specified sum to the payee or bearer. They've historically been widely used in Japan for short-term financing and as loan security. A valid promissory note must include specific elements: the words "promissory note," an unconditional promise to pay, the amount, maturity date, and the maker's signature.

Bills of exchange (kawase tegata) work differently: the drawer orders a third party (the drawee) to pay a specified sum to the payee or bearer. The drawee must accept the bill before becoming obligated to pay. Bills of exchange are less common in modern Japanese commercial practice but remain recognized in law.

Rights and liabilities of parties

• A holder in due course (zengi no sojisha) takes the instrument free from most defenses. To qualify, the holder must have acquired the instrument for value, in good faith, and without notice of defects or defenses.
• Liability follows a chain of responsibility based on each party's role (maker, drawer, endorser). All liable parties bear joint and several liability (rentai sekinin), meaning the holder can pursue any one of them for the full amount.
• Presentment (teiji) and notice of dishonor (fuwatari tsūchi) rules govern the procedures for demanding payment and notifying parties when payment is refused.
• The statute of limitations for claims on negotiable instruments is shorter than for ordinary contracts, encouraging prompt resolution.

Agency and partnerships

Agency and partnership structures facilitate business relationships and representation in commercial activities. These arrangements are governed by provisions in the Civil Code, Commercial Code, and specific partnership legislation.

Principal-agent relationships

Agency (dairi) allows an agent to act on behalf of a principal, creating legal rights and obligations that bind the principal directly.

Three concepts define the scope of an agent's power:

• Actual authority (jitsuryoku) arises from express or implied agreement between principal and agent.
• Apparent authority (hyōmenshugi) protects third parties who reasonably rely on an agent's appearance of authority, even if the agent exceeded their actual authority.
• Ratification (ninshō) allows a principal to retroactively approve an agent's unauthorized acts, making them binding after the fact.

Agents owe several duties to their principal:

• Duty of care (chūi gimu): act with reasonable skill and diligence
• Duty of loyalty (chūjitsu gimu): act in the principal's best interests
• Duty to account (keisan gimu): report on transactions conducted on the principal's behalf

Partnership formation and dissolution

General partnerships (nin'i kumiai) are formed by agreement between partners to engage in joint business activities. Partners share unlimited liability for partnership debts, and profits and losses are divided according to the partnership agreement (or equally if not specified).

Limited partnerships (yūgen sekinin jigyō kumiai, or LPS) allow limited liability partners alongside general partners. Limited partners' liability is capped at their capital contribution, but they generally cannot participate in management without losing that liability protection.

Dissolution occurs when any of the following happens:

1. The partnership term expires
2. The partnership's purpose is completed
3. Partners unanimously agree to dissolve
4. A partner dies, goes bankrupt, or withdraws (unless the agreement provides otherwise)

After dissolution, the winding up process involves settling partnership debts first, then distributing remaining assets among partners.

Corporate transactions

Corporate transactions encompass activities that significantly impact company structure, ownership, and governance. They're regulated under the Companies Act, the Financial Instruments and Exchange Act, and industry-specific laws.

Mergers and acquisitions

Mergers (gappei) come in two forms:

• Absorption-type merger (kyūshū gappei): one company survives and absorbs the other(s)
• Consolidation-type merger (shinsetsu gappei): a new company is formed from the merging entities

Acquisitions can take several forms:

• Share acquisitions (kabushiki shutoku): purchasing a controlling stake in the target company
• Asset acquisitions (shisan shutoku): purchasing specific assets or business divisions
• Tender offers (kōkai kaitsuke): required for large-scale acquisitions of shares in publicly listed companies

The due diligence (deyū dirijiensu) process involves thorough investigation of the target's financial, legal, and operational status before completing the transaction. Regulatory approvals may also be required, particularly antitrust clearance from the Japan Fair Trade Commission (JFTC).

Corporate governance issues

• The board of directors (torishimariyaku kai) is central to Japanese corporate governance. There's been a strong trend toward increasing outside directors (shagai torishimariyaku) to enhance oversight and independence, particularly after the 2015 Corporate Governance Code.
• Shareholder protections include derivative actions (daihyō soshō), which let shareholders sue on behalf of the company for directors' breaches of duty, and appraisal rights (kabushiki kaitori seikyūken), which allow dissenting shareholders to demand fair buyout of their shares in certain corporate transactions.
• Disclosure requirements ensure transparency: listed companies must follow timely disclosure (tekiji kaiji) rules and maintain internal control systems (naibu tōsei) for accurate financial reporting and compliance.
• Corporate social responsibility (CSR) and ESG (environmental, social, and governance) factors are playing an increasingly significant role in Japanese corporate governance and investor expectations.

International commercial transactions

International commercial transactions involve cross-border business activities subject to both domestic and international legal frameworks. Japan's participation in trade agreements and conventions shapes how these transactions are governed.

Choice of law

• The party autonomy principle allows contracting parties to choose the governing law for their international contracts. The choice must be express or clearly demonstrated by the contract's terms or circumstances.
• Without a choice, Japanese courts apply the law of the country with the closest connection to the contract, considering factors like place of performance, parties' places of business, and the nature of the transaction.
• Mandatory rules (kyōkō hōki) of the forum may override the chosen law in matters of public policy or consumer protection.
• Renvoi (tensō) is generally not accepted in commercial matters; courts apply the substantive law of the chosen jurisdiction rather than its conflict of laws rules.

Dispute resolution mechanisms

• Litigation in Japanese courts is available for international commercial disputes. Jurisdiction depends on factors like the defendant's domicile, place of performance, or the parties' agreement. Foreign judgments can be recognized and enforced if they meet specific requirements under Japanese law.
• International commercial arbitration is increasingly popular. The Japan Arbitration Act, based on the UNCITRAL Model Law, provides a modern framework. The Japan Commercial Arbitration Association (JCAA) offers institutional arbitration services.
• Mediation and conciliation provide alternatives for amicable resolution. The JCAA offers mediation services, and court-annexed mediation (chōtei) is available in some commercial cases.
• Investment treaty arbitration is available for disputes between foreign investors and the Japanese government under bilateral investment treaties (BITs) and free trade agreements (FTAs).

Consumer protection laws

Consumer protection laws address the power imbalance between businesses and individual consumers. The Consumer Contract Act and the Product Liability Act form the core of Japan's consumer protection framework, supplemented by industry-specific regulations.

Unfair contract terms

The Consumer Contract Act prohibits unfair terms in consumer contracts that unreasonably disadvantage consumers. Courts can nullify unconscionable clauses (futekisei jōkō) that significantly impair consumer interests.

Examples of potentially unfair terms include:

• Excessive liquidated damages clauses
• Unilateral modification rights for businesses
• Unreasonable limitations on consumer rights or remedies

Transparency requirements also mandate that contract terms be clear and understandable for consumers.

Product liability

The Product Liability Act imposes strict liability on manufacturers for defective products that cause damage to life, body, or property. This means the consumer does not need to prove the manufacturer was negligent, only that the product was defective.

Defect (kekkan) is defined broadly to include design defects, manufacturing defects, and warning/labeling defects.

The consumer must prove three things:

1. The product had a defect
2. They suffered damage
3. The defect caused the damage

Statute of limitations for product liability claims:

• 3 years from when the consumer learns of the damage and the liable party
• 10 years from product delivery (extended for latent health effects)

Manufacturers can raise certain defenses, including the state-of-the-art defense (the defect could not have been discovered given the scientific knowledge available at the time of manufacture) and compliance with mandatory standards set by public authorities.

E-commerce and digital transactions

E-commerce in Japan is governed by a combination of general commercial laws and specific regulations for online business. The Act on Special Provisions to the Civil Code Concerning Electronic Consumer Contracts and Electronic Acceptance Notice provides the core legal framework for online transactions.

Online contract formation

Electronic contracts are generally recognized as valid and enforceable in Japan. Click-wrap and browse-wrap agreements are commonly used, though courts assess enforceability based on factors like the visibility of terms and whether the consumer had a genuine opportunity to review them.

A cooling-off period allows consumers to cancel certain online contracts within a specified timeframe (typically 8 days), particularly for transactions covered by the Specified Commercial Transactions Act.

Electronic signatures are recognized under the Act on Electronic Signatures and Certification Business. Qualified electronic signatures carry the same legal effect as handwritten signatures.

Data protection and privacy

The Act on the Protection of Personal Information (APPI) governs the collection, use, and transfer of personal data. Key principles include:

• Purpose limitation: data must be collected and used for specified, explicit purposes
• Data minimization: only necessary data should be collected and retained
• Transparency: individuals must be informed about data collection and processing

Cross-border data transfers are subject to specific APPI requirements, generally requiring adequate protection in the receiving country or the individual's consent.

Organizations must implement cybersecurity measures to protect personal data from unauthorized access or breaches.

Individuals have the following rights under APPI:

• Right to access their personal data
• Right to request correction of inaccurate data
• Right to request cessation of use in certain circumstances

Commercial dispute resolution

Japan's legal system offers various mechanisms for resolving commercial disputes. There's a strong cultural and institutional preference for amicable settlement, and mediation or conciliation is often integrated into formal legal processes.

Litigation vs alternative methods

Litigation in Japanese courts has several distinctive features:

• Heavy emphasis on documentary evidence over oral testimony
• Judge-led fact-finding with limited discovery (no American-style depositions or broad document requests)
• Multiple hearing sessions spread over months rather than a single continuous trial

Arbitration is gaining popularity for complex commercial disputes. The Japan Arbitration Act (based on the UNCITRAL Model Law) provides a modern framework. Advantages include confidentiality, procedural flexibility, and international enforceability of awards.

Mediation and conciliation are widely used. Court-annexed mediation (chōtei) is available for many civil disputes, and private mediation through institutions like the JCAA offers another path. Expert determination is sometimes used for technical disputes, with the expert's decision often binding on the parties.

Enforcement of judgments

Domestic judgments are enforced through court-supervised execution procedures:

• Compulsory execution (kyōsei shikkō) involves seizure and sale of the debtor's assets
• Provisional attachment (kari sashiosae) can secure assets pending final judgment

Foreign judgment recognition and enforcement requires meeting four conditions:

1. Reciprocity between Japan and the country of origin
2. Proper service of process on the defendant
3. The judgment is not contrary to Japanese public policy
4. The judgment is final and conclusive

Arbitral awards, both domestic and foreign, are enforceable under the Arbitration Act. The New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards applies to foreign awards.

Common enforcement challenges include locating the debtor's assets, dealing with complex corporate structures or overseas assets, and a cultural reluctance in some business contexts to pursue aggressive enforcement measures.
