Kochi paper factory producing pollution, Japan

After many decades of air and water pollution, citizen and fishermen groups in Kochi city initiated a movement to remove the paper pulp factory. They resorted to direct action. The factory closed down in 1972.


 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.

Project Details and Actors
Project DetailsResponding to an initiative from the Daio Seishi (pulp) Company of Ehime Prefecture, this neighbouring prefecture provided funds for the project and the Nishi Nippon Pulp Factory went into operation in 1951.

In the 1970s, an environmental group in Kochi City and a group formed to protect Urado Bay initiated a movement to remove the paper pulp factory. Urado Bay was polluted by the factory wastes flowing into the sea (some 13500t per day at that time) until residents stood up to apply mortar to the canal and stopped it. Since those days back in 1971, the water quality has improved

The factory closed down in 1972.

Development of AlternativesMany years later, in the 2000s, the Eco-Town Kochi City Business Plan aims to further expand a cluster of

recycling industries within the city’s harbour and industrial complex (which has a focus on wood, paper and related industries). Eco-Towns are planned in other formerly polluted industrial cities also.
Do you consider this as a success?Yes
Why? Explain briefly.The direct action of citizens (stopping toxic discharges by pouring cement to block the pipes) led to a court case against the activists. The mild sentences was considered a victory. The factory closed down in 1972.
