YAMAOKA Sanshiro


Visiting Professor




Sanshiro Yamaoka received his MBA from the Graduate of School of Business, Stanford University in California, and his BA from the International Christian University in Tokyo.

Professor Yamaoka has more than twenty years of experience in the financial industry as an investment analyst, banker, and asset manager. He was formerly a vice president of Capital International Research Inc. (CIRI), a research arm of one of the world's largest institutional investors, Capital Group Companies. During his nine years with CIRI, he served as an equity investment analyst, based in Tokyo, covering close to 120 domestic demand-driven Japanese companies in a wide range of fields including retailing, miscellaneous services, food, beverages and tobacco, cosmetics and household goods, as well as real estate.

Prior to joining Capital, Professor Yamaoka worked for ten years with the Industrial Bank of Japan (IBJ, now Mizuho Financial Group), where he spent his initial years as a statistical analyst of the bank's in-house business operations. After returning from his MBA studies at Stanford, Professor Yamaoka began his investment career at IBJ's subsidiary, IBJNW Asset Management Co. (now Asset Management One Co., Ltd.), where he was a fund manager of global fixed income and Japan's small cap equities.

Professor Yamaoka has been on AIU campus every autumn since 2014 to teach "ECN 450 -MBA Essentials." He also started instructing "ECN 300 - Management Principles and Practices" in 2021.

Outside of AIU, Professor Yamaoka runs Yamaoka & Co., his own consulting and investment firm. He also instructs management courses at Hitotsubashi University's Business School as well as Waseda University's Graduate School of Sports Sciences. He is also a professional theatrical actor.

Message to Students

I teach both advanced and basic courses on management at AIU by bringing all of my business experience as an ex-MBA student, professional investor, active CEO of a company and instructor of graduate schools, into the classes. However, "management" is not only about business. It is not only about top executives or senior managers of profit-oriented companies, either. Instead, it is closely related to your everyday activities on and off campus. Learning about management will improve your quality of life, too ;-). I look forward to the journey with you to explore the essence of management!
