Examining Causes of Dwellings in the Lowlands from the Upland Relocation Villages due to the Tsunami : Based on the Previous Researches by Yaichiro Yamaguchi and Survey Results before and after the Great East Japan Earthquake in Toni-Hongo
Hongo, Tonicho-cho, Kamaishi-City here at the Toni-Hongo is located in the tsunami-prone area the Sanriku coast, which is also known as the residential relocation to the uplands after the Showa Sanriku tsunami. In a previous study, Yaichiro Yamaguchi pointed out the concern of the “old site return” where the village was located before the disaster, but the “old site” was unable to live due to the construction of the Tsunami seawall. On the other hand, the number of dwellings was increasing in the “lowlands” including the flooded area of the Showa tsunami. In the Great East Japan Earthquake, the “highlands” were spared damage, while the “lowlands” were devastated. Reconstruction projects after the Great East Japan Earthquake legally prohibited residents from living in the tsunami inundation area, and resolved concerns about “dwellings in the lowlands.” In this study, we clarified the transition of the village in Tonicho Hongo after the relocation to a highlands, and the actual condition and factor group of “dwellings in the lowlands”.
