From the Tokugawa period (1760) onward Kochi City was famous for the production of papers, and paper manufacture has been a major industry there. As time went on, the rivers of Kochi became more and more polluted by paper-manufacturing discharges, and the people, particularly the fishermen, were increasingly threatened by the problem. According to the excellent description in the UNU report (1992) "Industrial Pollution in Japan" edited by Jun Ui, in the 1930s a pulp-processing plant was constructed, releasing even more effluent into the environment. In 1948 a new pulp complex was proposed for the old pulp plant site. The city administration and prefectural government supported the project while the local fishermen and the citizens were against it. The site was located within city limits and the plan included no facilities for treating industrial waste. The plan meant that the river running through residential areas to Urado Bay would be thoroughly polluted and there would be sulphur dioxide air-pollution problems to contend with as well. This groundswell of opposition continued after construction of the factory had begun in January 1949. In July of the same year the anti-factory citizens' movement and the company came to an agreement in relation to pollution prevention. The agreement read in part as follows: (a) The company will assume responsibility for damage done to the environment by factory operations, and will pay compensation.
