The prospectus of the Japanese Society for Active Fault Studies established in September 2007, refers to significance of active fault studies in Japan. Each scientist, engineer and person related to this filed has own views and expectations about future of active fault studies. In this short paper I emphasize my view on the selected fields and their importance for future active fault studies, including comprehensive understanding of active faults, official compilation of detailed active fault maps and inventories, Active Fault Acts for mitigation of seismic hazards, simulation of earthquakes based on active fault data, active fault studies related active folding, submarine active faults and roles of the Japanese Society of Active Fault Studies.
