In 1945, while still a student at Kyoto University, Masao Horiba, the current Supreme Counsel of HORIBA, set up the HORIBA Radio Laboratory in Karasuma-Gojo in Kyoto in order to continue nuclear physics research interrupted by Japan’s defeat in the war. The HORIBA Radio Laboratory built the capacitor needed for the high-speed calculator (computer in today’s terms) for nuclear physics experiments. This capacitor became renowned for its functions and quality, and HORIBA decided to start manufacturing it commercially.
However, construction of the factory was halted by the steep rise in the cost of materials due to the conflict in Korea. The only thing to be done was to market the pH meter they had built to control the pH value of the capacitor’s electrolyte. This pH meter was extremely well-received and before he knew it HORIBA was famous as a maker of pH meters.
In 1953, eight years after the formation of the HORIBA Radio Laboratory, HORIBA, Ltd. was established and took its first steps as a manufacturer of measurement instruments.
