We want to spread the fantastic qualities of Japanese paper files made with an unwavering commitment to Japanese paper

Our a company sells a wide range of paper, focusing on Japanese paper. We manufacture and sell processed paper products. Since its founding, we have focused on selling Japanese paper. We have endeavored to expand sales channels for special paper, processed paper, and general paper from that time. In 1959 (Showa 34), the manufacturing and sales division of foodservice industry-related products such as "chopstick bags” was established to respond to changes in the social environment, such as increasing awareness for health in today’s society and the "Japanese style" boom and the sophistication and diversification of corporate needs.
Paper products such as chopstick bags made by our company have been used for many years at many restaurants, including major Japanese bar chains and long-established restaurants. We have also been working on making products that are conscious of environmental issues.In recent years, we have acquired the FSC (CoC) certification system. We are developing FSC certified products for all of our products. We were among the first to develop antibacterial Japanese paper and manufacture and sell various paper products such as antibacterial Japanese paper files and antibacterial mask cases, which are in high demand due to COVID-19. We also handle many products related to shrines and temples and animation SP products with Japanese motifs. Our Japanese paper files, pocket bags, one-stroke paper, coasters, colored paper are highly popular.

We have been involved over the years in printing and processing Japanese paper

Our printing supports a wide range of printing, from offset printing to on-demand printing and letterpress printing. We also perform post-processes such as bag pasting, die cutting, folding, and foil stamping in-house, allowing us to meet the diverse needs of our customers. Unlike ordinary paper, Japanese paper contains a significant amount of paper dust. It has a rough surface, making it challenging to produce good-quality prints. This is why exceptional technology and ingenuity are required to make outstanding products. Thorough inspections are a must even for us, which boasts many years of experience. What makes us unique is our ability to provide original Japanese paper due to our business with Japanese paper manufacturers across the country. We can adjust the thickness, size, and drying speed of Japanese paper, and develop antibacterial Japanese paper using antibacterial agents. Our original Japanese paper is also available. Even for Japanese paper files, we use the maximum thickness of Japanese paper that can be made without producting waste, resulting in paper files that are not easily torn by specifying a special thickness and size.
Offset printing starts from 1,000 sheets. Orders below that are produced using an on-demand printing machine.
