Making a fresh start from January 2023 under the new name "Proterial, Ltd."

Since its original founding in 1910, the Company has grown by providing many unique high-performance materials developed with its high technological prowess, principally to markets related to mobility, industrial infrastructure, and electronics.

“Proterial” combines “pro-” with the word “material.”
