Reviving Rivers, Tracing Memories - Agano River Restoration Progress (June 2004)

The Agano River watershed in Niigata Prefecture is associated with the memory of Niigata Minamata Disease, a serious pollution that occurred in the 1960s. Methylmercury discharged from the Showa Denko Kase factory upstream was blamed as the cause, and residents suffered neurological disorders and other health problems through contaminated fish and shellfish. As a result, the Agano River has long been spoken of as a "negative symbol.

In the 2000s, Niigata Prefecture embarked on the "Agano River Watershed Restoration Project" to overcome this past. The restoration project was not limited to mere water quality improvement, but attracted nationwide attention as a "participatory model" in which watershed residents, government, and research institutions worked together. Specifically, the project involved the construction of sewage treatment facilities, the restoration of riverside reed beds, and the participation of children through environmental education, and the movement to reconstruct the river as a "place of living and learning" progressed.

In addition, activities to rediscover the history and nature of the region and link them to the pride of the local residents were also developed through the "Agano River Etochoda Project" and other projects. These attempts were not merely a matter of cleaning up the river, but a comprehensive approach that also involved changing the awareness of local residents and revitalizing local culture.

However, as of June 2004, there were still sludge in the riverbed and domestic and agricultural wastewater remaining in the watershed. In addition, the social aspects of dealing with past pollution victims and passing on fading memories were also issues that needed to be resolved.

Nevertheless, the challenge of the Agano River is now being used as a reference for other watershed restoration projects as a symbolic effort to link the region's past and future. The river, which has overcome the pain of pollution, is being revived as a place where a new relationship between people and nature can be reestablished.
