　Yahagi dam was constructed in 1972. Its height is about 100 meters. As the result, a drastic change has occurred in dry riverbed. Huge forest appeared here and there. The huge forest has threatened people s life-environment.

　This study analyses one area in headwaters of Yahagi River. In this area, people unite themselves across the boundary of communities and the border of town-administration. This crossover union is not only recent phenomenon. In Edo era, similar crossover union and medium scale structure have been emerged repetitiously. Thus, it is not citizen’s movement appears in cities after Modernization, but like as Gemeinshaft over rural communities. This Gemeinshaft can be guess as potential to recover rural communities functions lost with depopulation and aging to regulate themselves from environmental changing.
