Tatsuo Yasunaga

Tatsuo Yasunaga is the kind of guy who lets the résumé do the talking — and what a résumé it is. He joined Mitsui and Co. straight out of Tokyo University's engineering faculty in 1983, quietly grinding through one of Japan's most storied trading houses for over three decades, then in 2015 leapfrogged 32 colleagues in seniority to become president. Thirty-two. That's not luck; that's someone the people at the top looked at and said, this one's different. He ran the company through some genuinely choppy global waters, handed off the president title in 2021, and stepped up to chairman while also taking a vice-chair seat at Keidanren. He's a guy from Kikuma in Imabari, Ehime, who decided the boardroom was his arena and stayed in it. I find that kind of low-profile, long-game seriousness quietly compelling.
