Tsuyoshi Mitsuboshi

Tsuyoshi Mitsuboshi has been a portfolio manager at Dalton Investments, a firm known for value investing with activist tendencies in Japan. Dalton was one of the early foreign investment firms to engage Japanese company management on corporate governance issues — including cross-shareholdings, excess cash hoarding, and inefficient capital allocation — years before the Japanese government began pushing these reforms through Tokyo Stock Exchange requirements. The firm's long experience in Japan gave it deep cultural knowledge needed to navigate Japanese corporate culture while advocating for change. Dalton's patient approach — holding positions for years while engaging management in private dialogue before escalating to public campaigns — proved particularly effective in Japan, where cultural norms favor private resolution over public confrontation, and where patient investors who built genuine relationships with management often achieved better outcomes than more confrontational Western activist approaches.
