Takemitsu Takizaki

Keyence was the fortune-creating business

Forbes identifies Takizaki as the founder of Keyence, the Japanese supplier of sensors and electronic components used in factory automation. The reviewed record ties his wealth to the company he created rather than to an inherited operating business or preexisting family fortune. ^[1]

Keyence dates its founding to 1974 and says the company entered the U.S. market in 1985 before expanding globally in the 1990s. That progression turned a domestic automation business into an international supplier across manufacturing and research markets. ^[2]

The company's economic model centers on high-value automation and inspection equipment sold with direct technical support. Keyence says it now serves hundreds of thousands of customers across more than 100 countries, showing how a specialized industrial-products business scaled into the enterprise behind Takizaki's fortune. ^[2]

Founder ownership continued after management succession

Takizaki stepped down as Keyence chairman in 2015 but remained on the board and became honorary chairman, according to Forbes. Keyence's annual report likewise lists him as honorary chairman and director, preserving a formal governance link after day-to-day leadership passed to later executives. ^[1][3]

The evidence therefore supports a primarily self-created fortune built through company formation, international expansion and retained founder ownership. The sources reviewed for this profile do not establish a material inherited wealth base, while they directly connect Takizaki to Keyence from its creation through later governance roles. ^[1][2]
