Japanese billionaire Takemitsu Takizaki is the Founder and Chairman of Keyence Corporation, and has an estimated net worth of $16.8 billion as of May 2019.

Takizaki's estimated net worth of $8 billion comes from the establishment of Lead Electric in 1974. The company was later renamed Keyence, and creates sensors, barcode readers, vision systems, digital microscopes, and other electronic components for factory automation systems. Even though Keyence is labeled as the manufacturer, it specializes solely in product planning and development. It does not manufacture the final products, which are mainly manufactured at qualified contract manufacturing companies.

Since Keyence was founded in 1974, it has developed and built up a substantial pool of technology patents from its large R&D investments. It is now a global company with a network of 16 international corporations and more than 3,000 employees around the world. It has annual sales of $2 billion, and its stock price was up by 50% over the past year with the rising sales in the auto industry. Takizaki has further boosted its operations after he became the largest shareholder in JustSystems, one of the major software development companies in Japan.
