Company information
Since our founding in 1949, in the untapped field of counters (counting devices), our fundamental philosophy has been passed down through the years as we have expanded our business into various sectors. It is people who create products, and it is also people who use those products. No matter how much the times change, we believe that it is people who generate new value, and without connections with others, we cannot create the products that society demands. Our strength lies in the technical skills and connections we have cultivated over many years of history. Each individual strives to improve themselves and holds high aspirations, while valuing connections with all people. By combining diverse insights and experiences, we will contribute to building the future with new ideas that are not constrained by existing frameworks.
