A historical study on interaction between the water flowing in the Kakehashi river and the Komatsu-tenmangu shrine has been made. The Komatsu-tenmangu shrine was founded by the third dynast of Kaga-clan, Toshitsune Maeda in 1657 and was designated as a national important cultural property in 1961. This shrine is located at the water edge of the Kakehashi river. Recently, it has become clear that the location of the Komatsu-tenmangu shrine was determined on the basis of principles of the positive and negative, and the five natural elements, which originate in China. It is found that the ideal interaction between the water flowing in the Kakehashi river and the Komatsu-tenmangu shrine was hampered to some extent by the embankment works in 1936, but is still maintained. After a series of riparian works of the Kakehashi river in 1943, the Komatsu-tenmangu shrine never suffers from any flood due to the break on the embankment of the Kakehashi river, but experiences several floods of the tributary rivers, agricultural channels or drainage canals. An effective measure to improve the present state of interaction between the water flowing in the Kakehashi river and the Komatsu-tenmangu shrine has been introduced and discussed.
