Debris flow and its countermeasures in Japan
Summary Japan is an island lying off the east border of the Asian Continent. Its total area is about 370,000 $ km^{2} $ 75% of the whole land area of Japan is mountainous. The lowlands, chiefly plains and alluvial fans, that constitute the remaining 25% are formed from sediments which have flowed there from the mountains in the past. In these lowlands live 85% of our population of 110 million people. Geologically, japan is extremely fragile and her topography is very steep. Under these conditions, sediment disasters caused by debris flow have occurred by torrential downpours, typhoons or the seasonal rain front in every year somewhere in Japan. These sediment disasters are the most harmful natural disaster to human life and property in Japan. For this reason the Sabo Law (Erosion Control Law) was enacted in 1897, and the government has exerted every effort to prevent such disasters. Thus Japan is one of the most advanced countries with regard to the study and research of sediment disasters and to the development of countermeasures.
