Japan's Retail Investors Embrace Shareholder Activism

Shareholder activism is gaining traction among Japanese retail investors, with a recent survey showing that a majority support activists and other stock owners in pushing for changes in corporate management and other initiatives. Many listed companies in Japan see individual investors as stable shareholders and have been eager to increase this base as they accelerate the unwinding of cross-shareholding arrangements with business partners. While these efforts have led to a sharp rise in the number of individual shareholders, the strategy can backfire if retail investors begin to question management decisions and align their votes with activist campaigns. One company seeking to attract more individual investors is major supermarket operator Blue Zones Holdings (417A.T), which carried out its first stock split in about 10 years earlier in April. "We aim to build a more stable shareholder base by attracting a wider pool of retail investors," said Sumito Kawano, president of the company formerly known as Yaoko. Blue Zones is not alone. "Behind the trend are efforts by companies to build a stable shareholder base after reducing their cross-shareholding ties," said Yuki Seto, a researcher at the Daiwa Institute of Research in Tokyo. The cumulative number of individual shareholders reached a record 84 million at the end of March 2025, according to the Japan Securities Dealers Association. Another survey by the association indicates that, as of last year, about 80% of individual investors had held their shares for an average of at least one year, with the holding period largely unchanged over the past two decades. Many individuals hold onto their shares in anticipation of shareholder perks and other loyalty rewards, while the 2024 launch of the Nippon Individual Savings Account, a revamped tax-exempt program, has helped fuel the trend. The number of individual investors seeking quick profits remains limited, although it has increased since the introduction of online stock trading. Yet individual investors can no longer be considered stable shareholders. A survey by Nomura Securities shows that the proportion of individual investors exercising their voting rights at shareholders meetings rose to 72% in 2025, up around 20 percentage points from two decades earlier. The finding suggests that individual investors, long seen as silent shareholders, are beginning to change. Retail investors are increasingly stepping into corporate management battles. A proposal by Japanese company Bold Investment to overhaul the management of Ekitan (3646.T), a train timetable information service provider, secured about 80% support at an annual meeting in June, reflecting backing from individual shareholders, who make up roughly 60% of its ownership base. A 2024 survey by Link Saussure, an investor relations support provider, found that more than 50% of individual investors backed shareholder proposals at annual meetings held over the preceding year, citing "disregard for shareholder returns" and "distrust of corporate governance." However, even if companies improve earnings, it is by no means easy to retain individual shareholders. An analysis by Nikkei shows that the ratio of individual shareholders tends to drop once listed companies improve their returns on equity (ROE). As a company's earnings improve and its stock price rises, retail investors are often tempted to sell their holdings. This behavior has persisted since it first emerged during the prolonged stock price declines that began after the bursting of the bubble economy in the early 1990s. The trend also underscores individual investors' limited financial means. "Without the financial wherewithal of institutional investors, individuals tend to sell appreciated shares to finance subsequent investments," said Risa Imanishi, a consultant at Mitsubishi UFJ Trust and Banking. When companies view retail investors as silent shareholders and assume their support, management discipline can slacken. In fact, companies with a growing number of individual investors often experience slower improvements in ROE and sales growth, according to a study by Hiroyuki Ishikawa, a professor at Osaka Metropolitan University, and other researchers. "Eager to protect their positions, managers tend to prioritize securing stable shareholders through perks and other loyalty programs rather than focusing on growth," Ishikawa said. The key to gaining long-term investors is to provide clear explanations of growth strategies and management philosophies aimed at enhancing corporate value, thereby winning shareholders' trust and turning them into "fans" of the company's policies. Retail giant Aeon (8267.T), where individual investors account for about 30% of all shareholders, has been working toward this goal by holding annual sessions that encourage direct exchanges of opinions between top executives and shareholders. "I felt the company could continue to grow, so I won't sell my shares anytime soon," said a 30-something participant at such a meeting. Tsukasa Ojima, an adviser to Aeon, said, "Successfully cultivating 'fans' among shareholders depends on how deeply a company considers the benefits of both customers and shareholders in its management approach." Japanese companies may have little choice but to engage in dialogue with retail investors now that an increasing number of these shareholders are siding with activists.
