Saving the “Last Natural River in Japan” and Nagara River Estuary Dam

Debate over Building a Dam over Japan's Last Virgin River


Description:

The Ministry of Land, Infrastructure, Transport, and Tourism (MLIT) planned to build a dam on the Nagara River in the 1960s as part of nation's comprehensive water resources development policy. This policy corresponded with the trend of water policies at the time, including U.S. reclamation policies, in which rivers like the Missouri and Columbia were regarded as resources to be fully used for human beneficial purposes. When the Japanese government promulgated law to promote the development of water resources in 1961 and established the Japan Water Agency, it identified five major watersheds for comprehensive development, including the Kiso River-Nagara-River watershed that runs through the Nagoya industrial area. Other prominent watersheds were the Tone River watershed in the Tokyo area and the Yodo River watershed in the Osaka area. A series of dams were planned mainly to secure water supplies to expanding urban areas and industries.

On July 2, 1991, the New York Times published a half-page ad for the opposition group. This galvanized a number of letters to the Ministry of Land, Infrastructure, Transport and Tourism, asking it to stop the construction. Many Japanese books were published in the 1990s both by opposition groups and promoters.
