About SABO

In Japan, debris flows, slope failures, and landslides are caused by rainfall and earthquakes and have taken many precious lives and deprived people of their possessions including houses, fields, public facilities and many other things necessary for their livelihoods and social activities. Sediment-related disasters are generally called sediment disasters and the practice of preventing or mitigating these sediment disasters is called “Sabo.”
About 70% of Japan’s land area is mountainous, and the valleys and basins surrounded by mountains, the alluvial fans downstream, and the gentle slopes of the plateaus around volcanoes have been used as places for living and industrial activities for centuries. Given this type of topography, sabo technology has been particularly highly developed and is widespread. Sabo is now a Japanese word known throughout the world.
