Delegation of Authority in Japan Subsidiaries: How to Control Risk

A foreign parent company sets up an approval matrix for its Japan subsidiary. Contracts above a certain value require HQ sign-off. The policy is documented, circulated, and acknowledged by the representative director. Everyone assumes the company is protected. Then the representative director signs a major contract without asking — and HQ discovers that the contract is binding on the company regardless of what the internal policy said.

This scenario surprises foreign HQ teams more than almost any other feature of Japanese corporate law. Under the Companies Act, a representative director (daihyō torishimariyaku) holds comprehensive authority to represent the company in all judicial and extrajudicial acts. That authority is, by statute, comprehensive — and critically, internal restrictions on that authority cannot be asserted against a third party acting in good faith. An approval matrix that the representative director ignores does not make the resulting contract void. It makes the representative director a problem for HQ to deal with internally — but the company is still bound.

This article works through what HQ can and cannot control over a Japan subsidiary’s representative director, why internal policies alone do not solve the problem, and how to build a governance framework that actually constrains risk rather than creating a false sense of security.

Why HQ Cannot Simply “Limit” a Representative Director’s Authority in Japan

Article 349, paragraph 4 of the Companies Act provides that a representative director has the authority to engage in all judicial and extrajudicial acts relating to the business of the company. This is not a default that can be narrowed by contract or internal policy in a way that affects third parties. The same article specifies that any restriction on this representative authority cannot be asserted against a third party acting in good faith. In practical terms: the representative director’s power to bind the company is comprehensive from the perspective of anyone the company does business with, regardless of what the company has decided internally about who needs to approve what.

Foreign companies entering Japan tend to bring an assumption from their home jurisdiction that a documented authority matrix is itself a legal control — that if a manager exceeds their delegated authority, the resulting transaction can be challenged or unwound. In some jurisdictions, particularly where corporate authority is more narrowly defined by statute or where counterparties are expected to verify a signatory’s authority, this assumption holds more weight. In Japan, the legislative choice runs the other way: the law prioritises the reliability of transactions with the company over the company’s internal governance preferences. A counterparty dealing with a Japanese company’s representative director is generally entitled to assume that director has full authority to bind the company, and does not need to investigate the company’s internal approval rules.

There is a narrow exception: if the third party actually knew, or should have known through gross negligence, that the representative director was acting outside an internal restriction, the company may be able to avoid being bound. In practice, this exception is difficult to establish. A counterparty who received no notice of the company’s internal approval matrix, and who had no obvious reason to suspect the representative director was exceeding their authority, will generally be treated as acting in good faith — and the transaction stands.

The broader institutional structure that governs how Japanese companies allocate decision-making between shareholders, the board, and the representative director is covered in Corporate Governance in Japan: Boards, Statutory Auditors, and Shareholder Meetings. Understanding that structure is the necessary foundation for understanding why HQ’s control options are narrower than they initially appear.

What an Internal Approval Matrix Actually Controls — and What It Does Not

None of this means an internal approval matrix — a shokumu kengen kitei, or rules of authority, that sets out which decisions require which level of internal sign-off — is worthless. It performs a real function. It simply does not perform the function many foreign HQ teams assume it performs.

What an approval matrix does control:

It establishes the internal standard against which the representative director’s conduct can be measured. If the representative director signs a major contract without the required internal approval, that conduct can be the basis for an internal disciplinary action, a damages claim against the director personally for breach of their duty of care, or grounds for removal. The approval matrix is also useful evidence in establishing what the company expected, which matters for internal accountability and, in some circumstances, for the analysis of whether a counterparty’s good faith should be questioned.

What an approval matrix does not control:

It does not, by itself, prevent the representative director from binding the company to a transaction that violates it. It does not give HQ a basis to unwind a contract simply because the internal process was not followed. And it does not transfer any of the comprehensive representative authority away from the representative director to anyone else — the authority remains with that office regardless of what the matrix says about who should be consulted.

The gap between these two categories is exactly where foreign companies get into difficulty. They treat the approval matrix as a legal control on the company’s exposure to third parties, when it is actually a tool for internal governance and after-the-fact accountability. The two are related but not the same thing, and the difference only becomes visible when the representative director actually acts outside the matrix.

Where Foreign Companies Discover the Gap: Real Scenarios Where Internal Rules Failed

The gap between internal policy and external enforceability tends to surface in a recurring set of situations. Recognising the pattern is useful both for HQ teams reviewing their existing structure and for those designing a new one.

• The trusted local representative director who signs without asking. A common pattern: HQ appoints a long-tenured, well-regarded local executive as representative director, trusts their judgment, and treats the approval matrix as a formality rather than an actively enforced process. The representative director, accustomed to a degree of autonomy, signs a significant lease, a major supply contract, or a guarantee without going through the approval steps. The counterparty has no reason to know an internal process was bypassed. The contract is binding. HQ’s only recourse is against the director personally, not against the validity of the contract.
• The post-acquisition surprise. A foreign buyer acquires a Japanese company and retains the existing representative director during a transition period. The buyer assumes that its new approval matrix, circulated immediately after closing, constrains what the incumbent representative director can do. The representative director, operating under old habits or in active disagreement with the new ownership’s direction, enters into transactions the buyer would not have approved. Because the representative director’s statutory authority does not change simply because new internal rules have been issued, these transactions are generally binding on the company.
• The JV partner’s nominee director acting independently. In a joint venture where the Japanese partner’s nominee holds the representative director title, the foreign minority shareholder discovers that contractual reserved matters in the shareholder agreement — which would require the foreign party’s consent before certain decisions are made — do not prevent the representative director from binding the company if those reserved matters are violated. The foreign shareholder’s remedy is against the Japanese partner for breach of the SHA, not against the third-party transaction itself.
• The seal (inkan) handed to the wrong person. Japanese business practice still relies heavily on the company seal (jitsuin) for executing significant documents, and the representative director’s registered seal carries particular weight in establishing the authenticity of a document. Where the seal is not tightly controlled — kept accessible to staff beyond the representative director, or used by a deputy without clear authorisation — the company can find itself bound to documents executed by someone who appeared, from the seal’s presence, to have the requisite authority.

Whether a specific transaction can be challenged on the basis of a counterparty’s bad faith or gross negligence in failing to verify the representative director’s authority is a fact-specific question, and the threshold for establishing this is generally high. Specific situations involving unauthorized transactions should be reviewed by Japanese corporate counsel promptly, as the available remedies and their viability can be time-sensitive.

Board Resolutions and Shareholder Approval: How to Build in Structural Control

If internal policy alone does not bind third parties, the more durable forms of control come from mechanisms that are embedded in the Companies Act itself — because these operate at the level of corporate authority, not internal preference, and in some cases their absence can itself affect the validity of a transaction.

Board resolution requirements under the Companies Act:

For a company with a board of directors, the Companies Act itself requires board approval for certain categories of significant transaction — including the disposition or acquisition of material assets, large borrowings, and transactions involving a conflict of interest with a director. Where a transaction falls into one of these statutory categories and the required board resolution was not obtained, the legal analysis is different from a simple internal policy breach: the transaction’s validity may genuinely be open to challenge, particularly where the counterparty knew or should have known that board approval was required and had not been obtained.

However, the effect on the transaction’s validity as against a third party is not automatic: Japanese courts have generally held that a missing board resolution does not in itself render a transaction void against a third party who was not aware of, and had no obvious reason to investigate, the board approval requirement. The stronger position arises where the counterparty knew or should have known that the statutory approval had not been obtained — but establishing this is fact-specific and often difficult.

This grounding in statute does make the analysis more nuanced than a purely internal policy breach, but it should not be treated as a reliable mechanism for unwinding transactions with third parties who acted without notice of the deficiency.

Whether a specific transaction can be challenged on the basis of a missing statutory board resolution, and what the counterparty’s state of knowledge must be shown to be, requires case-specific legal analysis.

Designating categories as board matters in the articles:

Beyond the statutory minimum, a company’s articles of incorporation can expand the categories of decision that require board approval. Embedding additional categories at the articles level — rather than leaving them solely in an internal policy document — may be a more structured internal approach, but it does not by itself create the same level of protection as a statutory board requirement. As against a third party, the enforceability of an articles-based restriction remains subject to the same good-faith analysis described earlier: a counterparty who had no notice of the requirement, and no particular reason to investigate it, is generally not bound by what the articles say about internal approval.

HQ board representation:

The most direct way for HQ to gain a real-time check on significant decisions is to ensure that material matters genuinely pass through the board, and that HQ holds board seats sufficient to participate meaningfully in those resolutions. For a wholly-owned subsidiary, HQ controls board composition entirely. The practical step many foreign parents miss is ensuring that the board actually convenes and resolves on the matters that the articles or internal policy say should go to the board — rather than the representative director treating board approval as a formality to be obtained after the fact, or not at all.

Shareholder-level reserved matters:

Certain fundamental matters — amendments to the articles, mergers, large-scale share issuances — require shareholder approval as a matter of statute, and for a wholly-owned subsidiary HQ controls this entirely through its shareholding. This does not solve the day-to-day authority problem, but it is a meaningful structural backstop for the most consequential categories of corporate action.

The categories of transaction that statutorily require board approval, and the circumstances under which a missing board resolution affects a transaction’s validity as against a third party, are fact-specific and depend on the size and nature of the transaction relative to the company. The interaction between a counterparty’s knowledge and the enforceability of a missing board resolution requires case-specific legal analysis.

How to Design the HQ-Subsidiary Authority Framework So It Actually Works

Given that internal policy cannot, on its own, prevent a representative director from binding the company, an effective authority framework for a Japan subsidiary combines several layers — accepting that no single layer is sufficient on its own.

• Choose the representative director carefully, and reconsider the assumption that local autonomy is automatically appropriate. Because the representative director’s statutory authority is so broad, the selection of who holds that title is the single highest-leverage decision HQ makes in the governance structure. Some foreign parents appoint a HQ-based executive as a co-representative director alongside the local executive, which can add a practical layer of involvement in day-to-day workflows, but does not restrict either person’s statutory authority as against third parties: each co-representative director individually retains full authority to bind the company, and a third party dealing with either one is not required to obtain the other’s agreement.
• Push significant categories into the articles and the board, not just an internal policy document. As discussed above, decisions embedded at the articles and board-resolution level carry more weight than an internal approval matrix. Identify the small number of truly consequential categories — major contracts, borrowings, asset disposals, guarantees — and ensure those specifically pass through formal board process, not just internal sign-off.
• Control the seal. Restrict access to the registered company seal and establish a clear internal process for when and how it is used. This is a practical, not purely legal, control, but it remains one of the more effective day-to-day mechanisms for preventing unauthorised execution of documents in a system that still relies heavily on seals for significant transactions.
• Use term limits and active reappointment as a recurring point of leverage. Directors of a KK have a statutory maximum term under the Companies Act: the default maximum is two years (one year in certain company structures), which can be extended in non-public companies up to a maximum of ten years under the articles of incorporation., requiring active reappointment by shareholder resolution.For a wholly-owned subsidiary, this gives HQ — as the sole shareholder — a recurring, structurally guaranteed opportunity to reassess whether the existing representative director should continue, rather than relying solely on an ad hoc removal process if problems arise. Legal Compliance for Foreign Directors and Shareholders in Japan covers the broader scope of what a foreign shareholder can and cannot do in this position.
• Build escalation and notice clauses into key counterparty contracts where leverage exists. For the subsidiary’s most significant ongoing relationships — major suppliers, lenders, key customers — the company itself can negotiate provisions requiring particular forms of internal authorisation evidence before certain categories of amendment or commitment are accepted.This shifts a portion of the practical risk by giving the counterparty actual notice of the internal requirement, which is relevant to the good-faith analysis discussed earlier. How to Draft Contracts in Japan: Key Clauses for Foreign Businesses covers the broader framework for structuring these kinds of approval-related provisions into Japanese commercial contracts.

No combination of these measures eliminates the underlying fact that a representative director’s statutory authority is broad and difficult to displace as against third parties. What this combination achieves is a meaningful reduction in both the likelihood of an unauthorised decision occurring and the consequences if one does.

When Things Go Wrong: What HQ Can Do After an Unauthorized Decision

When an unauthorised decision has already happened, the available responses fall into two categories: challenging the transaction itself, and holding the representative director accountable. The two are not equally available, and understanding which applies is the first step toward an appropriate response.

Challenging the transaction: As discussed above, this is generally difficult unless the transaction falls into a category that statutorily required board approval, or unless there is credible evidence that the counterparty knew or should have known the representative director was acting outside their authority. The first step is establishing exactly which category the transaction falls into and gathering any evidence bearing on the counterparty’s knowledge. Time matters here: delay in raising the issue can itself be read as evidence that the company accepted the transaction.

Holding the representative director accountable: This is the more reliably available path. A representative director owes the company a duty of care and a duty of loyalty under the Companies Act. Acting outside an approved authority framework, particularly where it causes the company loss, can support a damages claim against the director personally. The company can also remove the representative director, which for a wholly-owned subsidiary is a matter of shareholder resolution that HQ controls directly. Removal does not undo the transaction, but it stops the same problem from recurring and signals internally that the conduct was not acceptable.

Reviewing whether the gap was structural: An unauthorised decision is often a signal that the underlying authority framework relied too heavily on internal policy and not enough on the structural mechanisms described above. The response to a specific incident should generally include a broader review of whether board approval requirements, seal controls, and director selection were adequate — not just a resolution of the immediate transaction.

The viability of a claim against the representative director for breach of duty, the standard for establishing such a breach, and the availability and timing of any challenge to the underlying transaction are all fact-specific and require prompt review by Japanese corporate counsel once an unauthorized decision has been identified.

Conclusion

The comprehensive authority that Japanese law gives a representative director is not a loophole or an oversight — it is a deliberate legislative choice to protect the reliability of transactions with Japanese companies. For HQ, the practical implication is that an internal approval matrix, however carefully drafted, is not a substitute for structural control. It is one layer in a framework that also needs to include thoughtful selection of who holds the representative director title, genuine use of board-level approval for consequential decisions, disciplined control of the company seal, and active use of the shareholder’s recurring leverage over director appointment.

The companies that discover this gap the hard way are usually the ones that built a detailed internal policy, assumed it functioned as a legal safeguard, and never tested that assumption against how Japanese corporate law actually allocates authority. The companies that avoid the problem are the ones that build the structural layers in from the start — and treat the internal policy as what it is: useful, but not sufficient on its own.
