T. Hasegawa was established in 1903 as Hasegawa Totaro Shoten in Tokyo, Japan by Totaro Hasegawa. In 1941, Shozo Hasegawa succeeded his father at the company. In 1961 T. Hasegawa Co., Ltd. was founded with Shozo Hasegawa as President and took over all business of Hasegawa Totaro Shoten. The new company established headquarters in the prestigious Nihon-bashi district of Tokyo. The strong demand for Hasegawa products resulted in establishing Hasegawa’s first overseas production facilities in California in 1978 and the formation of T. Hasegawa USA.
