About Tetsuo

Tetsuo leads our RTS Practice in Japan, where he advises clients on making rapid and significant performance improvements in both domestic and global markets. He has more than 30 years of experience working with Japanese companies of all sizes and at all stages of maturity, helping to drive strategic, operational, and governance changes. During his career, Tetsuo has held roles as president, chief transformation officer, and chief strategy officer.

Tetsuo first joined McKinsey in 1994 and served telecom, high-tech, and consumer-product industry clients until he left the firm in 1999. He spent 9 years at Goldman Sachs advising Japanese technology companies on major transitions through M&A. He was also appointed vice president of Sanyo Electric and Fujita through periods of major transformation. In 2009, he joined M3, a fast-growing medical internet venture led by McKinsey alumni. He went on to spend 5 years developing a new business as president of a group company where he helped drive growth in key strategic areas. Just before rejoining McKinsey in May 2016, he led an IPO for a Japanese manufacturing company owned by a private-equity firm.

Now returned to McKinsey, Tetsuo is playing a pivotal role in large scale RTS projects of Japanese companies, working closely with the CEO and CTO (Chief Transformation Officer) to drive transformations
