Masaru Ibuka

Ibuka popularised in Japan and abroad the idea that the first years of life were critical to development and that parents could strongly stimulate language, music, reading and other abilities during that period. His book and an association he supported helped trigger a genuine early education boom, sometimes summarised deterministically as "three years old is already too late".

Sony became involved in the major US controversy over dumping of Japanese televisions. The company participated in Japanese minimum export price arrangements and an exporters' association, elements invoked in antitrust proceedings. US measures had initially included Sony in a general finding of dumping.

Corporate trade policy controversy during Ibuka's presidency; no finding of personal wrongdoing

Gulf & Western, which had inherited Chromatron patents through Paramount, sued Sony in a US federal court, claiming that the company had breached a 1964 licensing agreement by refusing to provide technical information about Trinitron and its developments. The claimant sought access to technical records and possible damages.

Corporate litigation linked to Ibuka-led technology programme

Ibuka refused to adopt the dominant shadow-mask colour picture tube immediately and committed Sony to Chromatron. Despite years of development, the technology remained extremely difficult to manufacture: low yields, complex processes and relentlessly rising costs. Sony's official history states that the more the company tried to manufacture, the greater its losses became, to the point that Ibuka considered returning to shadow-mask technology.

Sony's rapid growth transformed its labour relations. In May 1961, on the company's fifteenth anniversary, the progressive faction of the trade union organised a strike. Sony's official history acknowledges that the episode forced Ibuka and Morita to confront the internal employment problems of a company that had become much larger.

After deciding to purchase a transistor licence from Western Electric, Ibuka sought authorisation from Japan's Ministry of International Trade and Industry. MITI responded that a company still regarded as a small workshop had no realistic prospect of manufacturing such complex technology and considered his plan imprudent, while major Japanese groups entered the sector through more comprehensive technology transfers.

Sony archival account documenting government resistance and subsequent authorisation

In the founding prospectus written in 1946, Ibuka explained that at Japan Precision Instrument he had worked with several engineers to develop and manufacture "new military equipment". He also participated in a wartime research committee where he met Akio Morita, then a technical lieutenant representing the Navy.
