The second in an ongoing series designed to guide foreign companies through the critical steps of establishing operations in Japan. While Part I focused on strategic planning and market entry considerations, this instalment examines the key legal entity types available to foreign businesses. Selecting the appropriate structure—whether branch, subsidiary, or hybrid—can significantly affect your operational flexibility, tax exposure, regulatory obligations, and long-term scalability. As with any overseas expansion, integrating financial and legal planning from the outset is essential to ensuring a smooth and successful launch.
II. Defining the Legal Structures
Understanding the fundamental nature of each available structure is crucial before undertaking a comparative analysis.
A. Prioritise Financial Integration from the Outset
Before deciding on a legal structure, it’s critical to align your financial planning with your overall Japan entry strategy. Bringing your finance team into the process early—rather than as an afterthought—will help avoid common pitfalls. Many companies significantly overestimate the costs of entering the Japanese market, leading to overly conservative budgeting and inefficient allocation of resources. Remember, your Japanese entity is not an isolated venture but a functional extension of your global operations. Taking a structured, financially informed approach from the beginning will smooth the path to regulatory compliance, ensure realistic forecasting, and support long-term sustainability.
B. Branch Office (Shiten - 支店)
A Branch Office, or Shiten, established by a foreign company in Japan is legally considered an extension of the parent entity, operating under its corporate umbrella. It does not possess its own separate legal personality under Japanese law; rather, it functions based on decisions and instructions flowing from the foreign head office. Despite being an extension, a branch office is empowered to conduct continuous business transactions and sales activities within Japan.
Functionally, a registered branch office can operate much like a domestic company. It can enter into contracts, generate revenue, open Japanese bank accounts, lease office space and equipment, and hire local employees, all under its registered name. Employees hired by the branch are subject to Japanese labor laws.
To operate legally, a foreign company establishing a branch must register it with the relevant Legal Affairs Bureau. A key requirement for this registration is the appointment of at least one Representative in Japan who must be a resident of the country (though not necessarily a Japanese national). This resident representative acts on behalf of the foreign company concerning the branch's operations.
C. Subsidiary: Kabushiki Kaisha (KK - 株式会社 - Joint-Stock Corporation)
A Kabushiki Kaisha (KK), often translated as a "stock company" or "joint-stock corporation," is a distinct legal entity incorporated under the Japanese Companies Act. Crucially, it possesses a legal personality separate and independent from its foreign parent company or any other shareholders. This separation is the foundation of the limited liability principle associated with subsidiaries.
The KK is the most traditional, prevalent, and widely recognized form of corporation in Japan, dating back to the late 19th century. All publicly traded companies in Japan adopt the KK structure, contributing to its high level of prestige and credibility within the business community.
Structurally, a KK is owned by its shareholders, who provide capital in exchange for shares. Management is typically entrusted to directors appointed by the shareholders. The establishment of a KK requires the drafting and, importantly, notarization of its Articles of Incorporation (Teikan), which define the company's purpose, structure, and rules. Depending on its size and governance choices, a KK may be required to have a board of directors (typically comprising at least three individuals for certain structures) and statutory auditors. KKs are also obligated to hold regular general meetings of shareholders, usually annually after the close of the fiscal year, to approve financial statements and make key decisions.
D. Subsidiary: Godo Kaisha (GK - 合同会社 - Limited Liability Company)
Similar to the KK, a Godo Kaisha (GK) is also a distinct legal entity incorporated under Japanese law, possessing a legal personality separate from its foreign parent or other members. It is often described as Japan's equivalent of a Limited Liability Company (LLC) found in other jurisdictions. The GK structure was introduced relatively recently under the Companies Act revision in 2006.
The defining characteristic of a GK lies in its simpler and more flexible internal structure compared to a KK. In a typical GK, the investors (referred to as "members" rather than shareholders) are also the managers of the company. This fusion of ownership and management allows for potentially faster decision-making and less formal governance procedures. Unlike KKs, GKs are generally not required to hold annual member meetings or publicly disclose their financial results. Establishing a GK also requires Articles of Incorporation (Teikan), but critically, these do not need to be notarised, simplifying the setup process.
