Company information
Since its establishment in 1898, our company has embraced a spirit of innovation and a focus on technology, tackling new fields. We have grown into a unique paper company with a wide range of technical fields, engaging not only in printing paper but also in information paper, inkjet paper, specialty functional paper, photographic printing paper, and even electronic materials, CTP printing plates, and printing equipment. We have particularly contributed to the development of information media such as printing, publishing, and photography. Currently, the information society is rapidly transitioning to a structure that does not require paper media due to digitalization. There is a demand for the transformation of existing businesses and challenges in new fields in response to these societal changes.
