Board Meetings & Written Resolutions in Japan: Practical Rules

After establishing a Japanese subsidiary, many foreign parent companies quickly encounter practical governance questions:

• Is a board meeting always required?
• Can decisions be made by written consent instead?
• Does head office approval automatically validate corporate actions in Japan?

Under the Japanese Companies Act, board procedures are structured but flexible. However, misunderstandings—particularly around written resolutions and representative director authority—can expose companies to internal governance weaknesses and legal risk.

This article explains how board meetings and written resolutions operate in practice under Japanese law, and what foreign-owned companies should pay attention to.

1. When Is a Board of Directors Required?

In Japan, not all companies are required to have a board of directors.

There are two primary structures:

• Company with a Board of Directors (Torishimariyaku-kai Setchi Kaisha)
• Company without a Board (single or multiple directors)

A company with three or more directors may establish a board, but it is not mandatory unless certain governance structures are adopted.

Many foreign-owned subsidiaries operate with:

• One representative director, or
• A small number of directors without formally establishing a board.

In companies without a board:

• Each director generally has authority to represent the company
• Decisions are made at the director level rather than through formal board meetings

Understanding which structure applies is critical, as procedural requirements differ significantly.

2. Board Meetings: Core Legal Requirements

Where a board is established, the Companies Act sets out formal requirements.

Key procedural elements include:

Notice of Meeting

• Directors must generally receive notice at least one week in advance
• The period may be shortened by the articles of incorporation

Quorum

• A majority of directors must participate

Voting

• Resolutions require a majority of attending directors

Minutes

• Minutes must be prepared and signed or sealed
• Proper recordkeeping is legally required

Board meetings may be held in person or remotely, provided directors can communicate in real time.

Japanese board practice is typically document-based and structured, with emphasis on formal resolution documentation.

3. Written Resolutions (Unanimous Consent Under Article 370)

One of the most frequently misunderstood aspects of Japanese governance is the written resolution system.

Under Article 370 of the Companies Act, a board resolution may be deemed adopted without holding a meeting if:

• All directors consent in writing (or electronically)
• Any statutory auditor does not object (if applicable)

This means that unanimous consent is required.

Unlike some jurisdictions where majority written consent is sufficient, Japan requires full agreement of all directors.

If even one director withholds consent, a formal board meeting must be convened.

In practice, written resolutions are commonly used for routine matters such as:

• Bank account openings
• Appointment of officers
• Approval of standard contracts
• Minor corporate changes

However, companies must carefully confirm that:

• The company has adopted board structure permitting Article 370 use
• No director has been excluded
• All required consents are properly documented

Failure to comply may render the resolution procedurally defective.

4. Board Meetings vs Written Resolutions: Practical Differences

From a legal standpoint, both methods produce valid corporate resolutions if properly executed. However, their risk profiles differ.

Board Meetings

• Allow discussion and clarification
• Create stronger evidentiary records
• Reduce future dispute risk

Written Resolutions

• Faster and administratively efficient
• Suitable for uncontested matters
• Require unanimous consent

For sensitive matters—such as major transactions, director compensation, or conflict-of-interest issues—formal meetings are often advisable.

5. Representative Director Authority and Internal Controls

Japanese law grants broad authority to the representative director.

Externally, the representative director can bind the company unless third parties are aware of internal limitations.

However:

• Internal approval policies do not automatically limit external authority
• Parent company instructions alone do not substitute for Japanese corporate procedures

This creates a common compliance gap for foreign subsidiaries.

For example:

• Head office approval without formal Japanese resolution
• English-only internal approvals without Japanese documentation
• Informal email approvals treated as corporate authorization

These practices may create governance weaknesses or evidentiary challenges.

6. Common Compliance Mistakes in Practice

Foreign-owned subsidiaries frequently encounter issues such as:

• Failing to prepare board minutes
• Using written resolutions without unanimous consent
• Confusing head office approval with valid Japanese corporate authorization
• Not maintaining Japanese-language corporate records
• Over-relying on representative director discretion without internal safeguards

Such weaknesses may surface during:

• Due diligence reviews
• Bank compliance checks
• Investor audits
• Shareholder disputes

Conclusion 

Board procedures in Japan are structured but not overly complex. However, their practical application often depends on the company’s specific governance structure, director composition, and internal approval practices.

For foreign-owned subsidiaries, risks typically arise not from intentional non-compliance, but from assumptions—such as believing that head office approval automatically satisfies Japanese corporate law requirements.

The distinction between board meetings and written resolutions may appear procedural, yet it can have significant implications in disputes, audits, or transactions.

Ensuring that board processes are properly aligned with Japanese legal requirements—and appropriately documented—remains an important part of maintaining sound governance and reducing long-term corporate risk.
