Abstract: Abstract The periphery area of Japan has experienced outflows of young people as well as the aging of population ahead of the core area. The Sanriku coast, which we pay attention to as the most severely affected area by the Great East Japan Earthquake, consists of small cities that demonstrate the typical demographic characteristics of the periphery. Chapter 4 showed that the earthquake gave further impetus for a negative feedback of population decline and the weakening of agglomeration forces. Population outflow is occurring because of negative self-organization driven by increased dispersion forces after the earthquake, triggered by housing problems, delay in restoring central business districts (CBD), and employment mismatches. Reconstruction policy should not be aimed at recovering the original population size, but at the realization of optimal population size for supporting an affluent life while effectively using the natural advantage existing in each region. To take in the vigor of robust external demand, it is necessary to use creativity to differentiate products and strengthen ties with regional core cities.
