Abstract: This paper is a report on the retrospection of flood control projects since 1867, when Japan made a new start as a modern state, and an expression of our view on prospects in futures. Since ancient times, rivers have played an important role in Japanese life, as it is a country that have developed on cultivation of rice in alluvial lowlands. Even before modern times, river projects had been carried out for the purpose of flood control and water utilization. Modern Japan's river projects have been developed on the base of this historical background, though it is an undeniable fact that they are far more developed in comparison with those projects in pre-modern days. For, they are conducted using the method of mechanized construction after making scientific plans based on the comprehension of hydraulic and hydrological phenomena expressed in terms of mathematical quantities and equations. These modern river technologies were introduced from the West and developed through inviting foreign engineers to Japan and sending Japanese engineers to study abroad.
