Dr. Seiuemon Inaba
Co-founder 1955Background
Engineer and automation pioneer who led Fujitsu's numerical-control work before FANUC became a separate company.
Role at FANUC Corporation
FANUC possesses a fascinating, unusual founding story, rooted in the state-sponsored technological rebuilding of post-war Japan and the brilliant, eccentric vision of a single engineering genius. The company's foundational origins trace back to 1956 within Fujitsu, the Japanese telecommunications and computer conglomerate. Fujitsu recognized that the future of industrial manufacturing required automation. They assigned Dr. Seiuemon Inaba, a brilliant, disciplined engineer, to lead an experimental research team to develop numerical control (NC) systems to automate machine tools. Dr. Inaba was a visionary who operated with dictatorial authority. He developed the first commercial NC system in Japan in 1958. His foundational philosophy was 'reliability above all else.' He understood that a factory line stopping because a computer crashed was a financial catastrophe. He demanded uncompromising quality control. In 1972, the division had become so successful and specialized that it was spun off from Fujitsu as an independent company named FANUC (Fuji Automatic NUmerical Control). Dr. Inaba's leadership style was legendary and eccentric. He demanded that everything in the company—the factories, the robots, the employee uniforms, and even the fleet of company cars—be painted a specific, bright 'FANUC Yellow' to signify the company's pride and high visibility. He built the company's headquarters deep in an isolated forest at the base of Mount Fuji, sealing the company off from media scrutiny and corporate espionage. Dr. Inaba's obsessive focus on reliability and guarded proprietary technology transformed a small Fujitsu research lab into the indispensable nervous system of the entire global manufacturing sector.
