Company information
Our company has celebrated its 70th anniversary as a paper trading company. In addition to paper, we also handle packaging materials based on flexible packaging. We have also focused on the sale of LED lighting and have started selling several original products. We offer not only standard LED lighting but also high color rendering LED lighting, LED base lighting for hospitals, and high ceiling LED lighting that can be used in harsh environments such as factories and warehouses. In recent years, we became the first distributor in Japan for ICWUSA, an American monitor arm manufacturer. Known for its robust construction designed for professional use, it stands out in terms of originality compared to other products. We have actual units on display in our showroom on the first floor of our headquarters. We invite you to visit us and experience them firsthand.
