Jesper Koll has been in Japan since 1985, when he arrived as a PhD researcher studying global finance. What began as an academic year at Kyoto University became a long-term professional and personal commitment to Japan. Over the decades, he built a distinguished career as one of Japan's most recognised economic and investment commentators, including senior roles as Chief Economist and Chief Strategist at Merrill Lynch Japan and Head of Research at JPMorgan. He has also worked in hedge funds, built his own company, and moved between large institutions and smaller entrepreneurial environments. His career arc reflects a deep adaptability to Japan's business culture, an ability to interpret Japan for global markets, and a leadership style grounded in credibility, humility, local insight, and trust.

Jesper Koll's leadership philosophy is rooted in one central belief: in Japan, numbers alone never tell the full story. Behind every figure sits a leader, a team, a community, and a set of relationships that must be understood before meaningful judgement can be made. His experience leading highly skilled research teams in Japan taught him that the Anglo-American model of purely empirical, numbers-first analysis was insufficient in the Japanese context. In Japan, insight came not only from data, but from the human relationships that allowed analysts to understand the people behind the companies they covered.

Koll argues that foreign executives in Japan must not assume that global best practice can simply be transferred into Tokyo. What works in New York, London, or Hong Kong will not necessarily work in Japan. The most successful leaders understand the importance of local adaptation. They defend the Japanese way of doing things to headquarters rather than merely transmitting headquarters' orders to Japan. This is where concepts such as nemawashi, consensus-building, ringi-sho, and uncertainty avoidance become important. They are not obstacles to leadership; they are part of the operating system leaders must learn to respect and use intelligently.

His own credibility as a leader came from being both a player and a coach. As head of research, he still wrote reports, met clients, appeared on television, spoke at conferences, answered difficult questions, and risked being wrong in public. This gave him standing among a team of highly specialised, confident, and sometimes prima donna analysts. Leadership, for Koll, was not about title or positional power. It was about showing that he could perform, protect the team, make others look good, and take responsibility when things went wrong.

Trust, in his view, is created through consistency, humility, and one-on-one relationships. He believes leaders should give credit to the team and take blame themselves. He also stresses the importance of psychological safety, especially in Japan, where fear of failure can limit creativity. Koll deliberately discussed his own mistakes and encouraged analysts to examine failed reports, not as shameful episodes but as learning opportunities. This approach helped reduce defensiveness and made it easier for talented people to speak openly.

Creativity, he believes, exists in Japanese teams j
