Abstract:The author analyzes the various conditions concerning on the environmental planning of Japanese rivers and proposes the future research directions, based on these analyses. At first, from a morphological viewpoint, river planning should be based on long time scales, especially on the engineering facilities, as being illustrated by several examples of dams. Secondary, any environmental river planning should be taken consideration as a part of the regional planning. And finally, the author claimed a river should be treated as a field of flowing regime, before consideration on biological preservation, by reviewing flow conditions, which are used to be decided by the traditional water usage right for irrigation purposes.

Key words: river restoration, morphology, environmental river planning, water usage right, return period
