Masaru Ibuka
Innovation philosopher who founded Sony and invented the Walkman through curiosity and engineer-first spirit
Masaru Ibuka (1908-1997) was a Japanese engineer and entrepreneur, co-founder of Sony Corporation. Born in Tochigi Prefecture in 1908, he was fascinated by machines and radio from an early age, and after graduating from Waseda University, he devoted himself to engineering research. After World War II ended in 1945, he established the Tokyo Telecommunications Research Institute in the ruins of Tokyo, and in 1946 issued the Sony Founding Prospectus, explicitly stating a corporate mission centered on technological innovation. His partnership with Akio Morita is one of the most famous technical+business complementary combinations in Japanese business history. He led the development of epoch-making products including Japan's first tape recorder (1950), transistor radio (1955), Trinitron color television (1968), and in 1979 drove the invention of the Walkman, fundamentally changing how humanity listens to music. In his later years he turned to education, publishing 'Kindergarten Is Too Late' in 1971, which influenced early childhood education concepts worldwide.
Methodologies
- Curiosity-Driven Product Innovation Method - Define products starting from engineers' personal curiosity, not from market research data
- Founding Mission Statement Design Method - Write a mission statement centered on engineer culture at the founding stage, making it the permanent anchor of company culture
Key decisions and timeline
- Graduated from Waseda University School of Science and Engineering with Bachelor of Engineering - Early recognition of engineering talent often comes from unconventional innovation projects, not classroom grades
- Founded Japan Measuring Instruments Company, Developed Optical and Acoustic Equipment for Military - In special historical periods, finding the field with the most urgent technological demand is an effective path for engineer entrepreneurs
- Founded Tokyo Telecommunications Research Institute in the Ruins of Tokyo - Great companies are often born in the most difficult environments; scarce resources actually stimulate the greatest creativity
Beliefs and mental models
- Belief 1 - Masaru Ibuka believed that true technological breakthroughs come from engineers' pure curiosity about the unknown, not from market research or commercial needs. The Walkman was born not from consumer research but from Ibuka's personal desire to listen to music while traveling. He said: We don't do market research; we create markets.
- Belief 2 - In 1946, when founding Tokyo Telecommunications Industry (later renamed Sony), Ibuka wrote the Founding Prospectus, explicitly stating: the company's purpose is to create an ideal workplace for engineers and contribute to Japan's reconstruction through technology. This prospectus became the foundation of Sony's corporate culture and his clearest expression of engineer culture taking priority over sales culture.
- Belief 3 - Ibuka firmly believed that excellent products should be aesthetically beautiful while being technically superior. The Walkman's design was not just about portability but a lifestyle aesthetic statement. He believed engineers should not only focus on function but also pursue the formal beauty of products — a philosophy that profoundly influenced Sony's product design.
