Giving shape to reliability, giving shape to dreams and pursuing new technologies for a better tomorrow



Industrial tools offered by NISHIGUCHI CO., LTD. are used for manufacturing critical components including engines, brakes, transmissions, steering systems and the like, which are genuinely life-critical components. For this reason, manufacturing of such industrial tools in itself is a mission consigned only to highly reliable manufacturers. We constantly question ourselves “How can we attain a special geometry while pushing the boundaries of precision?” We at NISHIGUCHI CO., LTD. approach developing cutting-edge industrial tools by keeping an eye on the world’s most advanced technical intelligence. All of the industrial tools we offer are custom-made exclusively for machining precision components, which are not attainable through the use of ordinary shop-bought tools. Our policy is to assume an unshrinking and uncompromising attitude even toward highly demanding technical requirements. We design and develop products like no other company by examining optimal materials and designs and infusing them with our own ideas in a professional manner. Also, by responding to our customers’ requirements, our technical staff will grow significantly as humans as well as professional engineers. We pride ourselves on being able to give all of our effort to develop cutting-edge technologies while developing ourselves.
