Commercial Agents & Distributors: Competition Law Traps in Japan

Foreign companies entering the Japanese market through agents or distributors typically arrive with contract templates designed for other jurisdictions. Those templates usually contain provisions — price controls, territorial exclusivity, sales restrictions — that are standard practice in the US or Europe. In Japan, several of them create antitrust risk that the company is often entirely unaware of.

Japan’s Antimonopoly Act (Dokusen Kinshi Hō — commonly called the “Dokkin Hō” or “AMA”) regulates a category of conduct called “unfair trade practices” (fusei na torihiki hōhō), which applies directly to distribution arrangements. Resale price maintenance, exclusive dealing obligations, and tying arrangements that might be legally unproblematic in a foreign company’s home market can constitute per se or near-per se violations under Japanese competition law. The Japan Fair Trade Commission (JFTC) enforces these rules actively and has taken action against foreign companies operating distribution networks in Japan.

The problem is compounded by the fact that the violations are often invisible at the contract drafting stage. A clause that instructs a distributor to sell at a “suggested retail price” looks like standard brand management. Under Japanese law, if that suggestion carries any practical compulsion, it is resale price maintenance — and resale price maintenance is treated as one of the most serious categories of unfair trade practice under the AMA.

Many of these risks ultimately arise from the way distribution agreements are drafted. For a broader discussion of contract drafting considerations under Japanese law, see our guide on How to Draft Contracts in Japan: Key Clauses for Foreign Businesses.

Why Distribution Agreements in Japan Need a Competition Law Review

In the EU, vertical agreements between suppliers and distributors are assessed under a block exemption framework — many standard distribution arrangements are presumptively lawful below certain market share thresholds. In the US, most vertical restraints are assessed under a rule of reason standard that gives considerable latitude to non-price restrictions. Japan does not have an equivalent block exemption, and the AMA’s unfair trade practices category covers certain vertical restraints on a near-per se basis. The result is that agreements that cleared legal review in Europe or the US can still contain provisions that are problematic in Japan.

The JFTC has published guidelines on distribution and business practices (ryūtsū torihiki kankō ni kansuru dokusen kinshi hō jō no shishin) that set out in some detail how it analyses vertical distribution arrangements. These guidelines identify the categories of restriction most likely to raise concerns. Foreign companies building distribution networks in Japan — and their HQ legal teams reviewing contract templates — should be familiar with the main risk categories before the agreement is signed, not after a JFTC inquiry has been opened.

The four categories that account for the majority of distribution-related competition law issues for foreign companies in Japan are: resale price maintenance, exclusive dealing and territorial restrictions, abuse of superior bargaining position, and — in certain supply relationships — Subcontract Act obligations. Each is addressed in the sections below.

Resale Price Maintenance: The Rule Foreign Companies Most Often Break

Resale price maintenance (RPM) — requiring a distributor to sell at a price set or approved by the supplier — is treated as a near-per se violation of the AMA. Unlike in the US, where RPM is analysed under a rule of reason following the Supreme Court’s 2007 decision in Leegin, or in the EU, where it is a hardcore restriction under the Vertical Block Exemption but subject to individual exemption arguments, the JFTC’s approach leaves very limited room for justification. If a distributor is required — or, in practice, compelled — to sell at a specified price, that is RPM regardless of the label applied to it in the contract.

The “suggested retail price” trap:

The most common pattern foreign companies encounter is the suggested retail price (kibou kourigakaku — literally “hoped-for retail price”). Communicating a suggested price to a distributor is not itself a violation. The violation arises when the suggestion is backed by practical enforcement — through monitoring, pressure on distributors who deviate, de-listing, reduced allocation, or termination threats. The JFTC looks at the commercial reality, not the contractual label. A “suggestion” that no distributor in practice deviates from, because the supplier’s commercial behaviour makes deviation commercially punishing, is treated as RPM.

The pattern that creates risk for foreign companies is typically this: the HQ marketing team insists on price consistency across markets as part of brand management. The Japan distributor is told the “recommended retail price.” The regional sales team monitors compliance and flags deviations. When a distributor discounts, it receives a communication from the supplier expressing concern. Over time, no distributor discounts because they have learned not to. None of this appears in the contract — but the commercial conduct constitutes RPM under Japanese law.

Minimum resale price clauses:

Some distribution agreements contain a floor price clause — the distributor may not sell below a specified minimum. This is RPM on its face. Whether the supplier’s rationale (protecting brand positioning, preventing free-riding) might mitigate the violation is a question that in practice rarely produces a clean clearance. The clause creates risk from the moment it is signed.

Whether specific commercial conduct — including pricing communications, monitoring practices, and responses to distributor discounting — constitutes RPM under the AMA requires assessment of the actual facts against current JFTC guidelines and enforcement practice. The analysis above reflects general JFTC policy as of the date of drafting.

Companies selling products through distributors should also consider how pricing practices interact with broader consumer-facing regulations. For more on this topic, see our guide on E-commerce and Consumer Protection Laws in Japan.

Exclusive Distribution Rights and the Line Between Legal and Illegal

Granting exclusive distribution rights to a single Japan distributor — appointing one company as the sole authorised distributor for a product or territory — is not inherently unlawful under the AMA. Exclusivity is a common and commercially legitimate arrangement. The competition law issue arises not from the exclusivity itself, but from the obligations attached to it that restrict competition more broadly.

Exclusive dealing (haitateki torihiki joken)

A condition requiring the distributor not to handle competing products — exclusive dealing — is regulated under the AMA as a potentially unfair trade practice. The JFTC’s analysis focuses on whether the restriction substantially restrains competition in a relevant market. Where the supplier has a significant market position in Japan, or where the exclusive dealing obligation covers a substantial part of the distribution network for a product category, the risk of a competition law concern increases. A supplier with a modest Japan market share applying an exclusive dealing obligation to a distributor in a competitive market is in a different position from a market-leading brand foreclosing access to its distributor network.

Territorial restrictions on resale (kōsoku jōken tsuki torihiki)

Restricting where a distributor may resell — for example, prohibiting sales outside a defined territory or to certain customer categories — falls under the AMA’s “restrictive dealing” category. Whether a particular restriction is unlawful depends on whether it substantially restrains competition. Active sales restrictions (prohibiting the distributor from proactively selling outside the territory) are more likely to raise concerns than passive sales restrictions (not requiring the distributor to fulfil unsolicited orders from outside the territory). Cross-territory sales to prevent parallel imports are a specific area where the JFTC and courts have applied scrutiny, particularly for branded goods.

The “we just got legal clearance in Europe” problem

Foreign companies frequently present distribution agreements to their Japan operations that have been reviewed and cleared under EU or US competition law. That clearance does not extend to Japan. The EU block exemption framework that permits exclusive dealing below a 30% market share threshold has no equivalent in Japan. An agreement structured to fall within the EU safe harbour may still contain provisions that trigger AMA concerns in a Japan context, and the HQ legal team’s sign-off under European competition law does not provide cover.

Whether a specific exclusive dealing or territorial restriction substantially restrains competition under the AMA requires assessment of the supplier’s market position in Japan, the scope of the distribution network affected, and current JFTC enforcement practice. Market share thresholds used in other jurisdictions are not directly applicable in Japan.

Abuse of Superior Bargaining Position: A Risk Large Foreign Companies Often Miss

The AMA’s prohibition on “abuse of superior bargaining position” (yūetsu-teki chii no ran’yō) is one of the provisions that most surprises foreign companies. It has no direct equivalent in US antitrust law, and while the EU has introduced a concept of relative economic dependence in some member states, it does not map cleanly onto the AMA provision. In Japan, it applies in the B2B context where one party’s superior bargaining position allows it to impose conditions that the other party cannot practically refuse.

The key elements the JFTC examines are:

Superior bargaining position: the supplier is in a position of relative economic power — due to brand strength, market position, or the distributor’s dependence on the relationship — such that the distributor cannot reasonably refuse the supplier’s demands without significant business harm.

Imposition of unjust disadvantage: the supplier uses that position to impose conditions that are disadvantageous to the distributor and that the distributor accepts only because of the power imbalance.

Conduct that the JFTC has identified as problematic: requiring the distributor to accept products it did not order; unilaterally reducing the agreed purchase price after delivery; requiring the distributor to bear costs that should be the supplier’s responsibility; and imposing obligations (such as participation in promotions or marketing activities) without adequate compensation.

For large foreign companies with strong brand recognition in Japan, the superior bargaining position element is not difficult for the JFTC to establish. The conduct that gives rise to the abuse is often normalised commercial practice in the supplier’s home market — requiring distributors to fund promotional activities, insisting on product returns, adjusting payment terms unilaterally. In Japan, where a distributor’s business is substantially dependent on the supplier’s product, these practices can constitute an AMA violation.

When Distribution Arrangements Trigger Additional Regulatory Risks

The Subcontract Act (Shitauke-hō): Where a distribution arrangement involves the manufacture, processing, repair, or provision of certain services by a smaller counterparty for a larger company — and where specific capital size thresholds are met on both sides — it may fall within the scope of the Subcontract Act rather than, or in addition to, the AMA. The Subcontract Act imposes mandatory obligations on the “ordering party” (the larger company), including requirements to issue written orders, pay on time, and refrain from unilaterally reducing the agreed price, returning goods, or buying at below-market prices. Violations are handled by the JFTC and the Small and Medium Enterprise Agency, and the Subcontract Act has stricter enforcement teeth than the general AMA unfair trade practice provisions in many practical situations.

Foreign companies frequently underestimate Subcontract Act exposure because the Act’s capital threshold rules are not intuitive. A foreign parent company’s paid-in capital is relevant for determining the capital size of the Japan operation, and a foreign company with a large balance sheet dealing with a smaller Japanese manufacturer or service provider may find its Japan operations classified as an “ordering party” subject to the Act’s full obligations — regardless of whether the foreign parent considers the Japan arrangement a “distribution” relationship in its own terms.

Regulated industries: In certain product categories — pharmaceuticals, medical devices, food products, financial services, alcohol — distribution arrangements are subject to sector-specific licensing and regulatory requirements that operate alongside, and in addition to, the competition law framework. A distribution agreement that is competition-law compliant may still require the distributor to hold specific licences, and the supplier may need to ensure that distribution is through licensed channels only. Structuring distribution in regulated sectors requires both competition law and regulatory compliance analysis.

Whether a specific distribution arrangement falls within the scope of the Subcontract Act depends on the capital sizes of both parties, the nature of the transaction, and the applicable thresholds. The threshold rules are not straightforward where a foreign parent’s capital is relevant. A specific assessment is required before concluding that the Subcontract Act does or does not apply.

Competition law compliance is only one part of the analysis. Many industries also require sector-specific licenses and regulatory approvals. For more information, see our guide on Business Licenses and Regulated Industries in Japan.

How to Structure Your Distribution Agreement to Reduce Legal Exposure

The starting point is almost always a review of the existing agreement — either the HQ template or a contract already in use in Japan. The goal is not to strip out all commercial terms but to identify the specific provisions that create AMA risk and modify them in a way that achieves the underlying commercial objective without the legal exposure. The following are the modifications that arise most frequently in practice.

On pricing: remove the compulsion, keep the communication. Communicating a suggested retail price to a distributor is not itself a violation. What creates the violation is monitoring compliance with the suggestion and applying commercial pressure on distributors who deviate. Review your commercial conduct — not just the contract text — to ensure that suggested prices are genuinely non-binding in practice. Where maximum price ceilings are used (as opposed to minimum floors), the AMA risk is substantially lower.

On exclusivity: document the commercial rationale. Exclusive distribution arrangements that are proportionate to the commercial need and do not foreclose competition in the relevant market can be defensible. Having a documented rationale — the distributor’s investment in market development, the need for consistent brand representation, the limited geographic scope — is relevant to any JFTC analysis. Where exclusive dealing obligations are included, consider whether they are genuinely necessary or whether “preferred supplier” status (with commercial incentives for focus) achieves the same result with less legal risk.

On superior bargaining position: review your commercial practices, not just your contract. The abuse of superior bargaining position provision is conduct-based, not contract-based. A clean distribution agreement does not immunise commercial practices that impose unjust disadvantage on a dependent distributor. Review what your sales and supply chain teams are actually doing — how returns are handled, how promotions are funded, how price adjustments are communicated — and compare those practices against the JFTC’s published guidance on what constitutes an abuse.

On Subcontract Act obligations: identify whether the Act applies before signing. If the relationship falls within the Subcontract Act’s scope, the mandatory obligations it imposes are not negotiable — they cannot be contracted out of. Identifying applicability at the outset avoids designing a commercial arrangement around terms that the Act makes unenforceable.

Apply Japan-law review to the whole package, not just the contract. The AMA’s unfair trade practice provisions apply to conduct as well as contractual terms. A competition law review of your Japan distribution arrangements should cover both the written agreement and the commercial practices your Japan team and regional management are applying in practice. The two need to be consistent — and both need to be compliant.

Conclusion

The competition law risks embedded in distribution agreements are not visible to HQ teams who are applying the analytical frameworks of other jurisdictions. An agreement that cleared EU competition law review, or that reflects standard practice in the US, can contain provisions that are near-per se violations of the AMA. The JFTC enforces actively, and the violations are not technical — resale price maintenance, exclusive dealing that forecloses competition, and abuse of bargaining position are substantive concerns with real consequences.

The modification required is not typically a complete redesign of the distribution model. It is a targeted review of the specific provisions and commercial practices that create AMA risk, with adjustments that preserve the commercial relationship while removing the legal exposure. Many foreign companies only discover these issues after a distributor relationship has already been established and changing commercial practices becomes difficult. The key is doing that review before the agreement is signed — or before a JFTC inquiry makes the problem visible.
