Japan sees record wave of shareholder activism in 2026

Governance reforms and investor pressure are reshaping corporate Japan as engagement rates continue to soar.

Japanese companies experienced a record number of activist proposals in 2026, highlighting a significant acceleration in shareholder engagement in one of the world’s most traditionally conservative corporate governance environments.

Activist investors filed 139 shareholder proposals at Japanese companies in the latest proxy season, the highest level on record, according to data from Japanese banking conglomerate Mitsubishi UFJ Trust Bank. The latest figure represents an increase from 112 in 2023, 124 in 2024, and 137 last year.

Japan has long been viewed as a difficult market for activists, with cross-shareholder arrangements and large cash reserves helping to insulate boards and management teams from external shareholder pressure. As a result, activist campaigns were less frequent and often less successful than in the U.S. or Europe.

However, that environment has changed significantly over the past decade following a series of reforms to Japan’s Corporate Governance and Stewardship Codes, as well as efforts by the Tokyo Stock Exchange to improve listed companies’ capital efficiency.

These reforms have attracted both domestic and international investors seeking to unlock value in companies they believe are underperforming or inefficiently managed.

While every campaign is different, common activist demands in Japan include higher dividends, larger share buyback programs, asset sales, spin-offs, and governance reforms such as appointing independent directors or improving board oversight.

The rise in proposals has been driven by a combination of foreign activist hedge funds, domestic institutional investors, pension funds, and proxy advisers.

Hong Kong-based Oasis Management has been among the most active investors, successfully backing the removal of Taiyo Holdings’ chief executive last year and now campaigning for leadership changes at Kyocera, Kadokawa, Tokyo Steel, and SMS.

Meanwhile, Elliott Investment Management recently scored a high-profile victory in its opposition to the terms of Toyota Industries’ buyout of forklift maker TICO, while Dalton Investments and UK-based AVI have pushed for governance reforms at Yakult and Wacom, respectively.

These campaigns highlight the growing willingness of investors to challenge Japanese management teams on issues ranging from capital allocation to corporate governance.

Japanese companies have already begun responding, with share buybacks reaching a record JPY18 trillion ($112.3 billion) in 2024, and many firms increasing dividend payouts.

Despite these changes, activism in Japan remains different from the more confrontational style often seen in Western markets.

Public proxy fights and hostile campaigns are still relatively uncommon, with many engagements taking place privately behind closed doors.

For investors, the trend is significant because it could help improve corporate efficiency and unlock value across a market that has long traded at lower valuations than many global peers.

The record number of shareholder proposals suggests that activism is no longer a niche phenomenon in Japan. Instead, it is becoming an increasingly important mechanism through which investors seek to influence corporate strategy and improve shareholder returns.
