As for the downstream area of Susobana River, large-scale river development was done by the vassalry with Tadateru Matsudaira at the Edo period beginning. However, as for this, the written historical records do not exist only with a few traditions. With the urban development in recent years, there are few traces that the river structure in Keicho period can be confirmed and investigated in the present Susobana River basin. In this paper, by inductive method it is tried to identify the early development mode of Susobana River in Keicho age on the basis of induction analysis of some obtained materials. These materials include the documents in the locally existing Edo period, the Nagano City map in Taisho era with that the figure of the river channel can be checked, the public administration documents in the early years of Meiji era which is taken into consideration with the map and added to the figure analysis. As a result, it is possible to estimate that the development of Susobana River was proceeded by the government officials from Koshu with the method of construction which is descended from the riparian work technology of the Koshu style to have arranged the double levee structure and the open levee structure used. Because together Hokkoku-Kaido Tanbajima-Zenkojijyuku route were constructed in the old River Susobana's flood zone, Kubodera irrigation was excavated at the same time, these were the comprehensive development which included flood control work, water utilization and a highway construction.
