This report addresses various issues related to slope disaster prevention in Japan in terms of analysis and design techniques. First, mechanical problems in analysis and design technology in practice were explained, and then, as peer-reviewed issues related to analysis and design technology in the field of slope disaster prevention, papers published in academic journals up to around 2000 and recent changes were described. In addition, the author typified and explained the errors in mathematical formulas in academic journals, which have been frequently observed even in recent years. In this connection, the importance of observing the laws of physics in academic fields is described. The applied research on analysis and design techniques is mainly focused on the field of performance-based design. The issues of research on performance-based design in the field of slope disaster prevention are explained in comparison with the field of port and harbor engineering and the field of geotechnical engineering. Next, examples of overseas applied research on slope protection are introduced, and the direction of applied research in the Japan Landslide Society is discussed.
