Abstract
This paper introduces the efforts toward the practical use of wave generation system. Firstly outline of the property of wave energy itself is briefly explained. Then the quantity of wave energy around Japan and the seasonal variation are indicated with focus on the contrast between the sides faced to the Sea of Japan and Pacific Ocean. Also, various apparatuses devised in order to extract wave energy are introduced pointing out the advantages and disadvantages. Then project for developing wave energy conversion technique held in Yamaguchi University is indicated. Basic idea, dynamic model for designing the apparatus are given, then the proposal is given for utilization with little disadvantages of unstable energy gain inevitable to natural energy.
