Tomoko Namba

Tomoko Namba's resume reads like someone who had already won. Born in 1962 in Niigata Prefecture, she went from Tsuda University to McKinsey, took an MBA at Harvard, and became the first woman to make partner at McKinsey's Japan office. Most people would have stayed there. Instead, in 1999, she founded DeNA and built one of Japan's largest mobile gaming and social network companies, proof that she was never merely an adviser to other people's businesses. The decision I keep returning to is 2011, when she stepped down as chief executive to focus on her family. Very few founders can put that seat down voluntarily. What impresses me more is that she came back, later serving as vice chair of the Japan Business Federation, one of the most senior seats in corporate Japan. She refused the usual trade-off between the company and a private life, and somehow kept both.
