TOKYO—When Sony said in March that it was offloading its television business to a new joint venture with a Chinese rival, many in Japan felt a pang of nostalgia for the heyday of the country’s consumer-electronics industry. This is true even though he has worked for the company since 1987, and is fluent in corporate lore about when color TV—and later, the Walkman and PlayStation—made Sony a household name. Since taking the top job last year, Totoki has made the TV deal, brought in chip giant TSMC to collaborate on Sony’s valuable image sensor and spun off Sony’s financial arm—a unit he once ran.
