I plotted all the Shinto shrines found in the Yasu river drainage area on a large scale topographic map and tried to find out a functional meaning on the location of each shrine. Historical elements of the area were also taken into consideration. The 374 Shinto shrines studied were classified into 8 categories ; type of mountain summit, type of mountain foot, type of water head, type of river bank, type of breach, type of port, type of irrigation reservoir, type of paddy in narrow.
