Company information
Since our founding in 1927, we have gained the trust of many through the manufacturing and sales of machine tools, screws, and industrial machinery and equipment. In addition, since being appointed as a specialist committee member for JIS standards for hexagon socket screws, steel taper pins, and oilers by the Industrial Technology Institute in 1955, we have been dedicated to the development of the industrial sector for over 50 years. Currently, we focus on the manufacturing and sales of machine tools, precision cutting tools, and high-quality screws, which have been our core business since our inception, and we have expanded our global product offerings to include OSG cutting tools, Ambraco products from the U.S. company SPS, and JST-branded industrial machinery and equipment, establishing a solid position in the industry. As the 21st century becomes increasingly complex and diverse, we aim to continue our efforts based on our fundamental principle of "sound management" since our founding, striving to be of service to everyone.
