On November 1, 2013, we changed our company name from "Maeda Metal Industry Co., Ltd." to "TONE Co., Ltd." with a determination to leap and grow as a further global company. We have expanded our field from professional working tools to torque management equipment and bolt fastening equipment, and we are also developing a new field of bolting equipment that combines the strengths of these products.
