The Obatake Seto, which locates in the Yamaguchi Pref. in western Japan, is famous for its strong tidal current. It sometimes makes ship navigation difficult. Casualties sometimes happen there because of strong tidal currents and complicated topography. Renewable and environmental friendly energy resources are inevitable to decrease the dependence with fossil fuels or nuclear energy. Authors pay attention the possibility on tidal current electric generation in the Obatake Seto. However, there is very few knowledge on spatial distribution of tidal currents around the Obtake Seto within 100 meters. In this study, properties of tidal currents are clarified through the field observation and numerical simulation from viewpoint of navigation safety and electric power generation.
