The respective vegetation cover ratios (VCRs) around 42 elementary schools in Kawasaki, Japan, were calculated by a process employing airborne remote sensing data. In addition, we obtained ranked scores evaluating various environmental conditions around each school using results from a written questionnaire completed by teachers at 111 elementary schools there. It was found that the relationship between the logarithm of the VCRs determined for a 150-m radius and the ranked scores evaluating the amount of existing vegetation surrounding each school could be predicted to fall between two regression lines. Those lines were calculated for the cases in which large, public-accessible areas with vegetation were present or not present. We also found that about 20% of VCRs corresponded to the neutral of ranked scores evaluating (i) the amount of existing vegetation and (ii) the overall environmental conditions sorrounding each school in the case large, public-accessible areas with vegetation were not present.
