Corporate Governance and Financial Performance in Japanese Firms

Corporate governance in Japan has long been shaped by a stakeholder-oriented model, in which firms balance the interests of shareholders, employees, main banks and other key constituencies. This system evolved from the post-war keiretsu networks and the main-bank relationships that provided stability and long-term financing, but it also faced criticism for prioritising internal cohesion over market transparency. Reforms introduced in the 2000s and 2010s, including the Corporate Governance Code and Stewardship Code, sought to enhance board independence, strengthen shareholder rights and encourage engagement from institutional investors. These changes were driven by corporate scandals, sluggish economic growth and pressure to converge with global best practice. Empirical evidence indicates that stronger board oversight, a higher proportion of outside directors and increased institutional ownership have been associated with improvements in return on equity, investment efficiency and risk management. Yet, the transition from a stakeholder to a more shareholder-oriented approach remains gradual and complex, with firms often hybridising governance practices to preserve long-term relationships while responding to market expectations. The interplay between governance structure and financial performance in Japan has significant implications for other economies with bank-centric systems or family-controlled enterprises, illustrating how tailored reforms can foster sustainable growth without abandoning entrenched institutional strengths.
