Founding Story

Masaru Ibuka and Akio Morita founded Tokyo Tsushin Kogyo in a bombed-out Tokyo department store in 1946. An early rice cooker failed, but the company built Japan's first magnetic tape recorder and, after licensing transistor technology from Western Electric, launched the TR-55 transistor radio in 1955. It adopted the name Sony in 1958, listed ADRs in New York in 1961 and later created the Trinitron TV, the Walkman, the CD with Philips, and PlayStation.

Masaru Ibuka

Co-founder 1946

Background

Masaru Ibuka possessed an incredibly rigorous, deeply resilient background in advanced electrical engineering, complex telecommunications research, and mass-market technological innovation. Having successfully graduated from Waseda University and operating as a fiercely dedicated researcher who developed highly complex thermal guidance systems for the Japanese military during the war, this intensely technical foundation provided the exact engineering mastery required to successfully pioneer the incredibly massive Sony technology pipeline.

Role at Sony Group Corp.

Masaru Ibuka was an absolutely legendary Japanese electrical engineer, fiercely visionary industrial pioneer, and the profoundly influential technical patriarch fundamentally responsible for inventing the highly revolutionary electronics that built the massive Sony corporate empire. Operating as an incredibly talented engineer in the devastating aftermath of World War II, Ibuka aggressively launched a small radio repair shop in a bombed-out Tokyo department store in 1946. Relentlessly partnering with Akio Morita to formally incorporate the Tokyo Telecommunications Engineering Corporation (later Sony), he fiercely drove the massive internal R&D that resulted in Japan's first magnetic tape recorder and the incredibly massive global commercialization of the transistor radio. His absolutely rigorous technical leadership completely revolutionized global consumer electronics, permanently establishing the absolute historic bedrock for the multi-billion dollar Sony monopoly.

Masaru Ibuka was born in 1908.

Akio Morita

Co-founder 1946

Background

Akio Morita was born on January 26, 1921, in Nagoya, Aichi Prefecture, Japan, into a sake-brewing family that had operated for fourteen generations. He studied physics at Osaka Imperial University and served as a naval research officer during World War II. After the war, despite family expectations that he would join the sake business, he invested family funds into Ibuka's fledgling electronics company and became its commercial driving force. Morita's skill was in international brand building, he was among the first Japanese business leaders to understand that Japanese companies could compete not on price but on quality and innovation, and he pursued that insight with remarkable strategic clarity and personal energy.

Role at Sony Group Corp.

Akio Morita co-founded Tokyo Tsushin Kogyo (Sony) in 1946 and served as its chairman and chief executive through much of the company's global expansion phase. He was the architect of Sony's American market strategy, relocating to New York with his family in 1963 to personally oversee the company's US operations and build retail relationships. He championed the decision to brand all Sony products under the Sony name rather than accepting private-label arrangements, a conviction that proved foundational to the company's global brand equity. Morita drove the Walkman project to completion in 1979 over the internal skepticism of engineers who doubted the commercial market for a headphone-only audio device. He orchestrated the acquisitions of CBS Records and Columbia Pictures in the 1980s, arguing that Sony needed to control software content as well as hardware. He suffered a cerebral hemorrhage in 1993 while playing tennis and never fully recovered, dying in October 1999. He was posthumously awarded the Presidential Medal of Freedom by President Clinton in 1999. Akio Morita was born in 1921.

Who Founded Sony? FAQ

Who were the co-founders of Sony and when did they establish the company?

Sony was co-founded by Masaru Ibuka (an engineer and inventor) and Akio Morita (a physicist and entrepreneur) on May 7, 1946, under the name Tokyo Tsushin Kogyo K.K. (Tokyo Telecommunications Engineering Corporation) in Tokyo, Japan.

How did Masaru Ibuka and Akio Morita first meet before founding Sony?

Ibuka and Morita first met during World War II while serving on a secretive Japanese military-civilian research committee tasked with developing thermal guidance systems for airborne weapons. Despite an age difference of 13 years, the two formed an immediate mutual bond based on respect for science and innovation.

What was the central philosophy in Masaru Ibuka's famous Sony Founding Prospectus?

Written by Ibuka in 1946, the prospectus stated the company's purpose: "To establish an ideal factory that stresses a spirit of freedom and open-mindedness, where engineers with sincere motivation can exercise their technological skills to the highest level, and to reconstruct Japan through technology without chasing mere profits."

What was Masaru Ibuka's background and educational training?

Born in 1908 in Nikko, Tochigi Prefecture, Ibuka graduated in 1933 from Waseda University's School of Science and Engineering. Known among his peers as "the genius inventor," he worked in photo-chemical laboratories and operated an instrument manufacturing business before founding Tokyo Tsushin Kogyo.

What was Akio Morita's family heritage and background?

Born in 1921 in Nagoya, Morita was the eldest son and 15th-generation heir to a prestigious sake, miso, and soy sauce brewing dynasty (Nenohi). Expected to take over the family brewing business, Morita was captivated by physics and electronics, convincing his father to allow him to study physics at Osaka Imperial University.

How did Ibuka and Morita divide their responsibilities in running Sony?

Ibuka served as the quiet, contemplative chief technologist and inventor who asked "Can we build this breakthrough device?", while Morita acted as the charismatic global marketer, financial negotiator, and diplomat who answered "Here is who will buy it and how we will brand it across the world."

How did Akio Morita pioneer global marketing for Japanese brands in America?

Morita recognized that post-war American consumers associated Japanese goods with cheap trinkets. In 1960, he established Sony Corporation of America, moved his family to Fifth Avenue in New York in 1963 to master American consumer psychographics, refused private-label OEM manufacturing contracts, and insisted on selling only premium Sony-branded products.

What role did Masaru Ibuka play in the creation of the Walkman?

In 1978, Ibuka enjoyed listening to classical opera on portable tape recorders during international flights, but found existing machines too heavy and bulky. He asked tape recorder engineer Nobutoshi Kihara to modify a Pressman reporter recorder by removing the recording circuit and adding stereo playback with lightweight headphones, creating the Walkman prototype.

What were Masaru Ibuka's contributions to early childhood education?

Beyond electronics, Ibuka was deeply passionate about early childhood cognitive development. In 1969, he founded the Early Development Association and authored the international bestseller "Kindergarten is Too Late!", arguing that the human brain develops its most critical neural connections before age three.

What international honors and recognitions did Akio Morita receive?

Morita received prestigious honors worldwide: he was awarded the Albert Medal from the Royal Society of Arts in the UK, appointed an Honorary Knight Commander of the British Empire (KBE) in 1992, awarded the French Legion of Honour, and was the sole Asian business leader named to Time Magazine's 20 most influential business titans of the 20th century.

How did Morita and Ibuka handle the naming of the company "Sony"?

In 1958, Morita proposed changing the company name from Tokyo Tsushin Kogyo to "Sony." The company's main bank, Mitsui Bank, strongly opposed dropping the word "Tsushin" (Telecommunications) from the corporate title, but Morita refused to compromise, arguing that a short, universally pronounceable trademark was essential for global brand identity.

What was the lasting cultural impact of the Ibuka-Morita partnership on global industry?

The Ibuka-Morita partnership fundamentally transformed the global perception of Japanese industry from low-cost copycats into world leaders in miniaturization, aesthetic design, and high-fidelity consumer electronics, laying the foundation for modern portable consumer technology.
