Company information
Our company was established as Joetsu Sangyo Co., Ltd. in May 1966, with a capital of 1 million yen. Initially, our main business was the sale of concrete secondary products and the sale of cast iron, rebar, and bolts and nuts used in these products. In August 1968, we built a factory specializing in concrete blocks in Fukuhashi, Joetsu City, and began manufacturing, marking the first step in our factory production. Since then, we have faced numerous challenges, and together with our employees, we have worked hard to overcome them and continue to grow. Being needed by someone is very important both as a company and as individuals. To continue being needed by our customers and the local community, we will pursue further internal reforms, improve our services and quality, and develop new products, contributing to society. We kindly ask for your continued support and encouragement in the future.
