Background
Masaru Ibuka was born on April 11, 1908, in Nikko, Tochigi Prefecture, Japan. He studied electrical engineering at Waseda University, graduating in 1933, and spent the prewar and wartime years developing military communications equipment. He is widely credited as the technical visionary behind Sony's early breakthrough products, including Japan's first tape recorder and the transistor radio. After the war, he rented space in a bombed-out Tokyo building and formed the nucleus of what would become Sony with a small group of engineers. His philosophy — that engineers should be given freedom to pursue technical excellence rather than simply filling market orders — shaped Sony's corporate culture for decades.
Founding Story
Masaru Ibuka co-founded Tokyo Tsushin Kogyo (later Sony Corporation) with Akio Morita in 1946, investing his technical expertise and wartime engineering experience into building Japan's first commercial tape recorder and transistor radio. As the company's chief engineer and eventual chairman, Ibuka established Sony's culture of technical innovation over incremental product improvement — a philosophy that produced the Walkman, the first commercial CD player, and the Trinitron television. His partnership with Morita was one of the most complementary in corporate history: Ibuka provided the engineering direction; Morita provided the commercial and marketing vision. After Sony's formal IPO and global expansion through the 1960s and 1970s, Ibuka gradually transitioned away from operational leadership, becoming chairman in 1971 and honorary chairman in 1976. He died in December 1997, having lived to see the company he founded become one of the world's most recognized brands.
