Birth of the"OK Green ��� Series"

1949

The origins of the machine-made paper (newsprint paper and printing paper) business can be traced back to the establishment of Shoshi
Kaisha advocated by Eiichi Shibusawa in 1873, which laid the foundation for the Oji Group. Tomakomai Mill began operations in 1910 andestablished a domestic self-sufficiency system for newsprint paper. We continued to provide a stable supply of newsprint paper and printing
paper, supporting Japan's economic growth. Since then, paper has been developed to meet the requirements of the times, such as lighter
weight, colorization, multi-functionality, and environmental friendliness, and continues to evolve today.
