Electrical Installation and Piping Series

Since our founding in 1923, we have built over a century of history guided by our founder's spirit: “Never compromise on the quality of our pliers.” We combine the skilled craftsmanship of human hands with the rationality of optimizing processes suitable for automation. Driven by our responsibility to preserve Japan's traditional manufacturing heritage for future generations and share it with the world, we unite the power of tool manufacturing professionals. We develop tool brands that support craftsmen and transform the industry.
