Imperial University of Tokyo (present the University of Tokyo), which was the first educational organization for studying and learning these fields. After the laboratory was established, two foreign teachers were invited and taught SABO until 1909. In 1909, Dr. Moroto went to Vienna, Austria, to study SABO under F. WANG. He not only studied in Vienna but also visited many places where SABO projects were executed, for example, in France, Germany, Switzerland, Italy, Czech, Poland, Croatia and Montenegro. Through these studies, he gained much knowledge and technology concerning SABO. Just after coming back to Japan, Dr. Moroto became a professor at the Laboratory of SABO, the Imperial University of Tokyo. He produced some technical books and introduced new technology from Europe in many places in Japan. As a professor, he brought up the next generation and promoted research on erosion control technology and forest hydrology. In this paper the footprint Dr. Moroto left are described in the incipient period of modern SABO on the basis of a large literature and field investigation. This paper will contribute to future exchanges between Japan and European countries in the field of SABO based on these historical relationships.
