立山砂防·与土砂的斗争～世界引以为傲的防灾遗产～

This video begins with an animated drama depicting the people who resolved to battle against sediment after a massive collapse occurred within the Tateyama Caldera due to the Ansei Great Earthquake (Hida-Etchu Earthquake, 1858). The situation in Toyama Prefecture was so dire that when the Dutch civil engineer Johannis de Rijke, invited to Toyama in 1891 (Meiji 24), saw the state of the caldera, he remarked, "The treatment of this collapsed area is beyond remedy" and that "the entire mountain needs to be covered with copper plates." From the Taisho to Showa periods, Dr. Masao Akagi, known as the "Father of Sabo (erosion control)," planned and oversaw the construction of various sabo dams, and sabo engineering works continue to this day. Using a mix of CG and live-action footage, the video explains the role and value of the Tateyama Sabo system. It explores how the Toyama region and its people have confronted repeated historical disasters, and what value the Tateyama Sabo system—built through the efforts of civil engineers, administrators, and other involved individuals—holds. The work is crafted to be easily understandable even for beginners.
