History of Tosoh America

In 1964, Madoka Tashiro, who would go on to become a 53-year veteran of Tosoh, and Tosoh Corporation's chairman and CEO from 2001 to 2009, opened the company's first overseas office in New York. 

That office was the start of a 40-year expansion by the company. By 1989 Tosoh had accumulated a good number of subsidiaries in North America, and it established Tosoh America, Inc. in that year to function as a holding company for several of those subsidiaries. Later in 2001, Tosoh America, Inc. itself was enlarged as a regional headquarters.
