The Asahikawa Plant focuses on kraft paper bags for Hokkaido industries such as beet sugar, potato starch, powdered milk, flour milling and rice/barley, as well as cut sheets and small roll wrapping paper. The Niigata Plant centers on rice paper bags and is the company's only facility equipped to produce pinch bags, and it also has cleanroom equipment for bags used to package optical products such as materials for computer screens, plus sales of Niigata-produced polished rice. The Maebashi Plant produces heavy-duty polyethylene bags, light single bags and tube sheets, and uses one of only a few converter printing machines in Japan to make high-quality gusset bags with micro-perforation, embossing and gusset processing. The Saitama Plant makes kraft paper bags for food and chemicals and was the first in the company to obtain ISO 9001, producing sewn bags, pasted-bottom bags, easy-open bags and seal/over-tape bags. The company is positioned within the Nippon Paper Group, and in July 2013 the group opened a "Packaging Products Website." It exhibits at trade events such as Tokyo Pack 2012. Its recent public notices reflect active investment and market response: a 2026 notice on business collaboration with Sato Sangyo Co., Ltd. in the heavy-duty bag field; a 2026 notice on acquiring sugar polyethylene bag manufacturing equipment and starting that business; 2026 notices on polyethylene product response to Middle East conditions and kraft paper product price revisions; a 2024 headquarters relocation notice; 2024 and 2022 product price revisions; and 2016 and 2014 headquarters and Asahikawa Plant relocation notices.
