While mayor of Izumo, Japan, Tetsundo Iwakuni, a former investment banker for Merrill Lynch, was voted the most popular mayor in Japan. Having lived abroad (in England, France, and the United States) as an investment banker, Iwakuni had left his corporate career to pursue public service. After a productive term as mayor of Izumo, he ran unsuccessfully for mayor of Tokyo. This case describes his personal life and career and ends with his election to the Japanese Diet (Parliament) from a Tokyo district. The case provides students with an opportunity to explore leadership style, career-management issues, and international management principles from a Japanese point of view. A teaching note is available to registered faculty, along with a video interview with Testundo Iwakuni to enhance student learning.
