PurposeBuilding on the institutional theory perspective on corporate governance change and based on interviews with investor relations (IR) managers in large Japanese companies, this study aims to examine Japanese IR managers’ perceptions of the influence of foreign shareholders on Japan’s corporate governance reform and stakeholder-based system. The paper examines tensions, conflicts and collaborations among different stakeholders involved in corporate governance changes in Japan, especially in the areas of firm ownership, employment relations and boards of directors. The paper explains why convergence does not happen in some large Japanese companies by investigating Japanese managers’ responses to and perceptions of foreign shareholders in multiple corporate contexts.Design/methodology/approachThe author conducted in-depth interviews with ten IR managers at large, listed Japanese companies in Kyoto and Tokyo and two managers at foreign investment banks in Tokyo, between 2018 and 2021.FindingsThis paper explores five themes that emerged from my interviews: Chief executive officers’ (CEOs’) mixed perceptions of foreign investors, the effectiveness of CEO compensation and outside directors, managers’ reluctance to accept stock price-driven business strategies, foreign investors’ engagement vs investments in index funds and gender patterns, including the effectiveness of token female outside directors. The Japanese companies the author looked at incorporated foreign shareholders as consultants and adopted a few major shareholder-based customs, such as CEOs communicating with investors, having outside directors, increasing CEO compensation and slimming down unprofitable parts of the business via restructuring and downsizing. Simultaneously, they resisted a few major shareholder-based practices. Foreign shareholders’ pressure revealed tensions and contradictions between the Japanese stakeholder system and shareholder primacy-based customs.Originality/valueThis paper is one of the few qualitative studies that explores Japanese IR managers’ responses to and perceptions of foreign shareholders in corporate governance reform, with a particular focus on ownership, employment relations and board members. This paper provides examples of tension, conflict and cooperation between Japanese managers and foreign investors, as seen through the eyes of Japanese IR managers. Examining changes in Japan’s stakeholder-based system of corporate governance reform enables us to better understand the processes by which, with vigorous pressure from government and foreign shareholders, a non-western country like Japan may adopt shareholder-based customs and how such a change may also lead to institutional changes.
