Yamaha Corporation of America has officially named Seiichi Yamaguchi as its new President, effective April 1, 2026. Yamaguchi will take the helm of the Buena Park-based subsidiary, which oversees the distribution of musical instruments and professional audio products across the United States. He succeeds Tom Sumner, who is scheduled to retire from the company later in the year.

Yamaguchi currently serves as the Managing Executive Officer and Executive General Manager of the Musical Instruments Business Unit at Yamaha Corporation in Japan. His extensive background in global instrument sales and business strategy is expected to drive the company’s next phase of growth in the American market. The appointment marks a significant transition for the division, which remains a cornerstone of Yamaha's global operations.

Outgoing President Tom Sumner has been a fixture at Yamaha for decades, having first joined the organization in 1988. Since stepping into the presidency in 2018, Sumner has overseen significant shifts in the industry, including the expansion of Yamaha’s digital footprint and professional audio divisions. Reports from the Orange County Business Journal and Mixonline indicate that the leadership transition is designed to ensure stability as the brand continues to innovate in the musical technology landscape.
