By the age of 34, Akiko Naka has already experienced more career-wise than most people do in a lifetime.

She started by getting hired by Goldman Sachs Group Inc., where she worked as an equity saleswoman. When she left that job, she tried to make it as a professional manga artist. When that didn't work out, she landed a job at Facebook Inc.

And not content to leave it at that, she quit to establish her own company, a recruiting social network called Wantedly Inc. She took it public on the Tokyo Stock Exchange last year, and is one of the youngest women to head a Japanese-listed company.
