Abstract During the over half Century after the Second World War, Japan has experienced drastic transition on the river management with the surprising economical growth and the severe urbanization. Under these condition , the conflict of people between upstream and downstream regions has been arisen in several river basins where dam projects have planned. Over forty years, the Circumstances of the conflict from the upstream peopleís side. Based on our research, results on the conflict, we introduce three different examples as follows; First case is Kaneyama Town on the Tadami River Basin located in Tohoku District (Northern Japan). The town has a serious history since 1960ís, hydro-electric dam boom on the Tadami River, flood damage caused probably by dam-reservoir operation, removal of the part of hydro-electriceqipment, the environmental destruction with the lapse of the changeable socio-economical condition with the population decrease. Second case is Horai Town on the Toyo River Basin located in the Central Japan near Nagoya. As the town has suffered from the continuous dama projects nearly the half Century, the people were always worrying about their life establishment. Third case is Kitagawa Town on the Gokase River Basin located in Kyushu (Southern Japan). The town has been suffered from inundation throughout the history. It is very difficult to establish the flood control project in the flood-prone district. The population of above-mentioned towns are decreasing and always sacrificing against the neighboring towns. Three cases are the reverse side story with the economical growth in the urban regions in Japan.
