The Great East Japan Earthquake 2011 caused not only tsunami damage and a nuclear plant accident, but the world's largest scale liquefaction damage as well. According to the MILT, about 27,000 houses were damaged, the majority of which are located in Chiba Prefecture, the target of this research. This paper analyzes the results of a questionnaire survey of households that suffered damage in two cities affected by major liquefaction. The actual conditions corresponding to damage were recorded, and the impacts of subsidies were analyzed. Even in cases where households suffered the same level of liquefaction damage, administration subsidies differed according to city. The following three types of impact generated by administration subsidies for liquefaction countermeasures were confirmed statistically. (1) Direct impact: The existence of a subsidy affected the implementation of restoration construction. (2) Indirect impact: The existence of a subsidy led to a reduction of construction expense. (3) Indirect impact: The existence of a subsidy carried a consciousness of residential continuation and influenced a willingness to pay for re-liquefaction prevention.
