The specie of Fagacea in the conpound of 24 shrines in Toyota-cho and 21 shrines in Kikugawa-cho was investigated. Eleven species belonging to four genera, 7 broad-leaf evergreen species and 4 broad-leaf deciduous species, were identified: Q.glauca (in 36 shrines), Q.acuta (in 3), Q.gilva (in 4), Q.salicina (in 8), Q.myrsinaefolia (in 14), Q.sessilifolia (in 4), Castanopsis cuspidata (in 34), Q.aliena (in 1), Q.acutissima (in 2), Q.serrata (in 11), and Castanea crenata (in 9). The average number of species per a compound in Toyota-cho and Kikugawa-cho was 3.2 and 2.3, respectively. In this area, Q.glauca and C.cuspidata are dominant and common species; Q.glauca was observed in 80% of 45 shrines. C.cuspidate was in 76% of 45 shrines. To addition this, Q.gilva is found in 9% of 45 shrines in this area, although it has appeared in only 2% of 960 shrines which had been studied. These two also seem to be characteristic species in this area.
