Abstract
Kamikochi is one of the most famous places with alpine landscape in Japan. Various constructions, which mainly aim to disaster prevention, destroy the nature systems in Kamikochi. The Research Group for Natural History in Kamikochi was founded to contribute to solve the nature conservation problems in Kamikochi. Although natural history is getting clear by the researches of the group, the proposals of the group, which aimed to stop the constructions or to change the ways for disaster prevention, do not have accepted. It is important to find the ways to combine the results of the researches with the nature conservation activities.
