Japan — Registration & Annual Compliance

Japan’s commercial registration system is governed by the Companies Act (会社法, Kaisha-hō) and the Commercial Registration Act (商業登記法, Shōgyō Tōki-hō). This system formally records the existence, structure, and statutory particulars of both domestic and foreign business entities under Japanese law. Registration serves dual critical purposes: it grants legal personality (for domestic entities) and provides public notice, which is indispensable for validating transactions and clarifying liability.

Who must register

• Domestic entities: Joint-stock companies (Kabushiki Kaisha, KK), limited liability companies (Godo Kaisha, GK), partnerships, and other entity types as specified by the Companies Act. Registration is mandatory upon formation.
• Foreign entities: Any foreign corporation establishing a branch or representative office in Japan must register under the Commercial Registration Act before commencing business activities.

Legal effect of registration

• For domestic entities, formal registration with the Legal Affairs Bureau (法務局, Homukyoku) is the act that confers legal personality.
• For foreign entities, registration authorizes the branch to operate and formalizes the authority of the branch’s legal representative.

Registration authority

All commercial and corporate registrations—whether for formation, modification, or branch establishment—are handled by the Legal Affairs Bureau, under the Ministry of Justice (MoJ). The Bureau processes the filings using prescribed forms and maintains a publicly inspectable registry.

The statutes and operation guidelines are published by the Ministry of Justice. Although English-language explanations are sparse, the official Japanese-language resources constitute the definitive authority.

Under the Japanese Companies Act, a foreign company (any entity incorporated or organized outside Japan) must register with the Legal Affairs Bureau before engaging in “continuous transactions in Japan.” This threshold is set out primarily in Companies Act Article 818 and further interpreted by ministry guidance.

Definition of "continuous transactions":

• “Continuous transactions” means more than isolated, one-off activities—examples include maintaining an office, hiring employees, conducting regular sales, or otherwise engaging in lasting business operations.
• Statute and guidance do not define a strict quantitative threshold. However, the requirement is triggered if the company will repeatedly or continuously conduct business (including opening a branch, not just a representative office).

Pre-registration prohibition:

• A foreign company is prohibited from commencing continuous transactions until it completes commercial registration with the Legal Affairs Bureau (Companies Act Art. 818(1)).
• Even preparatory acts—such as signing ongoing contracts or hiring staff for a Japanese office—likely cross the “continuous” line and trigger the registration obligation.

Representative requirement & 3-week rule:

• A foreign company must appoint at least one resident Japan-based representative (Art. 817). Upon decision to open a branch (i.e., once commencing continuous transactions), registration must be filed within three weeks (Art. 818(1)).

Penalties for noncompliance:

• Violating the pre-registration prohibition (e.g., conducting continuous business without registration) exposes the foreign company and its Japan representatives to fines under Art. 979 and possible injunctions. In practice, banks, landlords, and counterparties will refuse business with an unregistered foreign entity.

• Note: Foreign companies opening only a "representative office" (no sales or contracts, strictly information gathering) commonly fall outside this threshold but must watch for factual triggers. Unable to confirm a comprehensive list of exempt activities as of 2024-07-11.

A foreign company—defined as any corporation or other entity incorporated outside Japan—must register with the Legal Affairs Bureau before conducting continuous business activities through a branch in Japan. This requirement is anchored in the Companies Act, Article 818. The law distinguishes between a branch office (which must register before engaging in business) and a representative office (which may limit itself to preparatory or liaison activities and, so long as it does not engage in sales or contracts, is not required to register). Ministry of Justice guidance confirms that activities limited to information gathering or coordination do not trigger the registration obligation; registration is required only if the foreign entity plans to transact business or maintain a branch.

When is registration required?

• The obligation arises if a foreign company will conduct “continuous transactions” in Japan. This includes regularly maintaining a place of business, hiring staff, or selling goods and services (Companies Act Art. 818; MoJ FAQ).
• The filing must be made within three weeks of the resolution to establish a branch (Art. 818(1)).

Who must register?

• Branch offices: Required to register before starting business.
• Representative offices: Not required to register, so long as only non-commercial activities are performed.

Required information and documents: Companies Act Article 933 specifies the information to be registered for a foreign company’s branch:

• Name, address, and governing law of the head company (Art. 933(1)(i)-(ii)).
• Purpose of business in Japan (Art. 933(1)(iii)).
• Name and address of each representative in Japan (must have at least one resident—Art. 817, 933(1)(v)-(vi)).
• Location of the branch (Art. 933(1)(iv)).
• Amount of stated capital, formation date of head office (Art. 933(1)(vii)-(viii)).

Supporting documentation generally includes: certified copy of formation documents, certificate of good standing from the home jurisdiction, Japan representative’s authorization evidence (MoJ FAQ).

Penalties for noncompliance:

• Conducting continuous transactions before registration can result in civil fines imposed on both the company and Japan-based representative(s) (Companies Act Art. 976, 979). The Act does not specify the fine amount in the English translation; unable to confirm the current range as of 2024-07-11.
• In practice, unregistered foreign branches face difficulty with banks, property landlords, and government agencies—these business consequences are industry custom, not statutory penalty.
