The UN emphasis the importance of building a bridge between science and policy*. The Mishima Numazu and Shimizu (MNS) environmental movement in 1963-1964 is really really turning point in Japan. After the movement, the Japanese environmental movement was spreading out all over Japan. Establishing the Japanese Environmental Impact Assessment (EIA) Law was delayed because of this movement. The core story related to science and policy is the conflict between the governmental EIA research group and the local EIA group. The government group used high-tech machines and money, but the local research group used high school students, local people, and local knowledge. For example, the government group did research by using a helicopter to check the wind direction, on the other hand, the local group used a carp-shaped streamer for examining the direction around the 5th of May in 1963. Japanese people usually raise carp-shaped streamers in front of the house to celebrate their children’s prosperity. Finally, local people, including farmers and fishermen studied hard to recognize the environmental impacts of their living areas and chose the local research group results.
