Japan\u2019s Kabushiki Kaisha share many features with global corporate governance concepts, but they also have unique institutional design and practical operation based on the Companies Act. Below, we explain the basic governance structure and key legal points under the Companies Act.<\/p>\n
<\/p>\n
1\uff0eMain Corporate Bodies o<\/span>f a Kabushiki Kaisha and Their Roles<\/strong><\/span><\/p>\n Under the Companies Act, the basic approach is the \u201cseparation of ownership and management,\u201d clearly distinguishing the roles of owners (shareholders) and managers (directors). However, in small companies, it is common in practice for the shareholder(s) and director(s) to be the same person(s), i.e., \u201cunity of ownership and management.\u201d<\/p>\n <\/p>\n Name<\/strong><\/p>\n<\/td>\n Role Description<\/strong><\/p>\n<\/td>\n<\/tr>\n Shareholder (Kabunushi)<\/strong><\/p>\n \u00a0<\/strong><\/p>\n<\/td>\n An investor in the company who constitutes the shareholders\u2019 meeting, the highest decision-making body. Shareholders have the authority to decide important matters for corporate governance, such as amending the articles of incorporation (Teikan) and appointing or removing officers.<\/p>\n<\/td>\n<\/tr>\n Director (Torishimariyaku)<\/strong><\/p>\n \u00a0<\/strong><\/p>\n<\/td>\n Appointed at the shareholders\u2019 meeting, directors are responsible for deciding and executing the company\u2019s business operations (day-to-day management). The relationship with the company is based on a mandate-type relationship(\u201cInin-Keiyaku\u201d), and directors owe the duty of care and the duty of loyalty. The term is generally two years, which may be extended up to ten years for a \u201cPrivate Company\u201d (Hi-koukai-kaisha). *Private Company means a company whose Articles of Incorporation restrict the transfer of all its shares.<\/p>\n<\/td>\n<\/tr>\n Representative Director (Daihyou-Torishimariyaku)<\/strong><\/p>\n \u00a0<\/strong><\/p>\n<\/td>\n Selected from among the directors, the representative director is legally vested with authority to represent the company in all judicial and non-judicial acts relating to its business. Although internal restrictions may be imposed on this authority, such internal restrictions generally cannot be asserted against a third party acting in good faith.<\/p>\n In Japanese practice, the representative director (Daihyou-Torishimariyaku) is required to register the company\u2019s representative seal with the Legal Affairs Bureau. Important contracts commonly require affixing the registered seal and attaching a seal certificate, reflecting a practice that is closely associated with Japan\u2019s seal system.<\/p>\n<\/td>\n<\/tr>\n Board of Directors (Torishimariyaku-kai)<\/strong><\/p>\n \u00a0<\/strong><\/p>\n<\/td>\n If a board of directors is established, at least three directors are required.<\/p>\n The board of directors makes decisions on day-to-day business execution, and the representative director carries out the execution. This structure provides organizational checks and balances.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n 2\uff0eLimited Liability as Shareholders vs. Potential Unlimited Liability as Managers<\/strong><\/span><\/p>\n The greatest advantage of choosing a Kabushiki Kaisha is the shareholders\u2019 \u201climited liability.\u201d Even if the business fails and the company becomes insolvent, shareholders\u2019 legal liability is, in principle, limited to the amount they invested. In other words, shareholders are not legally required to repay company debts to creditors using their personal assets. This strong liability shield allows investors to invest boldly and take on new market challenges without undue fear of unexpected losses.<\/p>\n <\/p>\n However, as noted above, in small Japanese companies it is common for the same person to serve both as shareholder (investor) and director (manager). In such cases, one may not be able to fully enjoy the practical benefit of \u201climited liability\u201d as a shareholder and may instead face situations in which the manager bears substantial personal responsibility.<\/p>\n The first example is fundraising. In Japanese lending practice, when a small company borrows from a bank or financial institution, the management, such as the representative director, may be required to act as a joint and several guarantors (Rentai-Hoshounin) (often referred to as \u201cmanagement guarantees\u201d). In such cases, if the company goes bankrupt, the manager may be obligated to repay the company\u2019s debt using personal assets based on the guarantee obligation. Although Japanese government guidelines have promoted lending that does not rely on management guarantees, this remains a practical issue that companies often face.<\/p>\n The second example is legal liability where management failure causes harm to third parties. Directors are obligated to perform their duties faithfully in compliance with laws and the articles of incorporation, including the duty of care and the duty of loyalty. If a director, in performing their duties, causes damage to a third party (e.g., a business counterparty) through \u201cbad faith or gross negligence,\u201d the director may be directly liable to compensate that third party from the director\u2019s personal assets. This is a heavy statutory responsibility imposed directly on an individual serving as a manager (director), separate from the principle of limited liability as a shareholder.<\/p>\n <\/p>\n 3\uff0eThree Key Rights of Owning Shares<\/strong><\/span><\/p>\n Holding shares means not only making an investment but also having strong rights protected by law. Key shareholder rights include the following three:<\/p>\n Name<\/strong><\/p>\n<\/td>\n Description of the Right<\/strong><\/p>\n<\/td>\n<\/tr>\n Voting Rights<\/strong><\/p>\n \u00a0<\/strong><\/p>\n<\/td>\n The right to vote at the shareholders\u2019 meeting on key corporate matters, such as amendments to the company rules (articles of incorporation), appointment or removal of directors, and other important resolutions.<\/p>\n<\/td>\n<\/tr>\n Right to Receive Dividends<\/strong><\/p>\n \u00a0<\/strong><\/p>\n<\/td>\n The right to receive dividends in proportion to the number of shares held when the company generates profits. Under the Companies Act, dividends are not automatically paid every year; they are subject to the legally distributable amount and the relevant corporate decision-making procedures.<\/p>\n<\/td>\n<\/tr>\n Right to Receive Residual Assets<\/strong><\/p>\n \u00a0<\/strong><\/p>\n<\/td>\n When the company is dissolved, the right to receive a distribution of the remaining assets after all debts have been repaid, in proportion to shareholding.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n Japan\u2019s Companies Act is relatively flexible. By issuing different classes of shares, it is possible to design various capital policies aligned with shareholder preferences (e.g., a foreign parent company), such as restricting voting rights or granting dividend preferences.<\/p>\n <\/p>\n 4\uff0eCommon Corporate Organization Models in Japan<\/strong><\/span><\/p>\n When incorporating in Japan, a common choice, especially at the early stage of a foreign company\u2019s entry into Japan, is a simple organizational model without a board of directors or a company auditor.<\/p>\n Item<\/strong><\/p>\n<\/td>\n Simple Model<\/strong><\/p>\n<\/td>\n Governance-Enhanced Model<\/strong><\/p>\n<\/td>\n<\/tr>\n Number of Directors<\/strong><\/p>\n<\/td>\n One or more (incorporation is possible with one)<\/p>\n<\/td>\n Three or more (if a board of directors is established, at least three directors are required)<\/p>\n<\/td>\n<\/tr>\n Board of Directors (Torishimariyaku-kai)<\/strong><\/p>\n<\/td>\n No (decisions can be made very quickly)<\/p>\n<\/td>\n Yes (organizational checks and balances function)<\/p>\n<\/td>\n<\/tr>\n Company Auditor* (Kansayaku)<\/strong><\/p>\n \u00a0<\/strong><\/p>\n<\/td>\n No (if no board of directors is established, appointing a company auditor is optional)<\/p>\n<\/td>\n Yes (in principle required if a board of directors is established)<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n *A company auditor (Kansayaku) is one of the audit bodies established under the Companies Act and is an officer who audits directors\u2019 execution of duties.<\/p>\n <\/p>\n 5\uff0eSummary<\/strong><\/span><\/p>\n The Kabushiki Kaisha structure is highly effective for gaining trust in Japanese society while controlling risk. Keeping in mind the two perspectives of \u201cownership (shareholders)\u201d and \u201cmanagement (directors)\u201d is key to business success in Japan.<\/p>\n <\/p>\n <\/p>\n Contact Us<\/span><\/strong><\/span><\/p>\n In our Japan Business Law Guide, we will continue to share useful information tosupport your business expansion and operations in Japan. <\/p>\n <\/p>","protected":false},"excerpt":{"rendered":" One of the most widely used corporate forms when starting a business in Japan is the \u201cKabushiki Kaisha (Kabush … <\/p>\n\n
