Established in Tokyo, Japan Cosmotec Corporation was founded by Rokuro Sekiguichi in 1992. Mr. Sekiguchi quickly developed a reputation for his uncompromising commitment to quality and reliability. He strongly believed that if he gave his word to a client, it must be kept - there were no exceptions. He also believed that if his work consistently exceeded the clients' expectations, then his business would grow. He was right.Today, Cosmotec is Japan's leading manufacturer of ultra high vacuum products. His son, Taku Sekiguchi is now the proud CEO of the company that he founded more than 20 years ago. Taku Sekiguchi shares his father's vision and is dedicated to manufacturing only the highest quality components. Each component is always designed with precision, quality and reliability in mind. Taku also has a keen interest in testing new materials and has been the driving force behind Cosmotec's ongoing commitment to innovation. What was once a small, family-run business is now Japan's leading manufacturer of ultra-high vacuum components.
