This study aims to define site selection characteristics of shrines affected by tsunamis in the coastal areas of the Sanriku region, to understand the differences between the locations of shrines that did or did not survive the disaster through field surveys and historical reviews. First, through the field survey, this research demonstrates that shrines in the area are generally located on ridge of mountains less likely to be affected by tsunamis and the destroyed shrines tend to be located near the low-lying coastline or on flatlands. Second, through the historical reviews, the characteristics of shrine locations have greatly changed since the middle of the 12th century. This research indicated that shrines were mostly positioned along the ridge line during the time of the ancient belief system and became more diverse during the medieval period from the mid-12th century onwards, when the culture of “kanjo,” the ceremonial transfer of a divided tutelary deity to a new location according to the enshrined deity's character, was introduced to the area. In addition to this general site selection characteristics, the experience from earlier tsunamis affects the re-selection of shrine sites. In conclusion, the site selection system for the shrines consists of global and local mechanisms. Finally, the author suggests the possibility of utilizing the shrine's site selection characteristics as a way to hand down the tsunami experience to the next generations.
