The purpose of this study was to clarify the salt-water tolerance of broadleaved trees on the basis of their damage and recovery in premises forests, shrine and temple groves. The superiority or inferiority of salt-water tolerance for each tree species was judged by the extent of flooding of trees due to a tsunami and by the growth condition based on the rate of leaves on the trees at each site, and the salt-water tolerance in the sites was ranked by collating the rankings at each site. As a result, it was inferred that Euonymus japonicus has a similar salt-water tolerance to Pinus thunbergii ; it is likely that such trees with high salt-water tolerance will be used in the replanting of coastal forests in the future. In addition, it was inferred that Zelkova serrata and Celtis sinensis have salt-water tolerance from the recovery of trees by progress of time. The superiority or inferiority of trees and the ranking of salt-water tolerance were performed using strict definitions with no logical inconsistencies, although few trees were investigated. Moreover, an objective conclusion without site-specific factors (i.e., microtopography and growth conditions) and with a limited influence at each site was reached by conducting an investigation of many sites.
