Abstract: We investigated the infestation of the termites to living cultivated Cryptomeria japonica trees and the distribution of termites on Yaku-shima Island. Leucotermes speratus was distributed in Cr. Japonica stands throughout the Island while, Coptotermes formosanus was restricted to Cr. japonica stands under 300m in altitude. Most important species, which infested living Cr. japonica, was Co. formosanus whose infestation reached at 6.5m above the ground in the nested tree. The percentage of infested trees by Co. formosanus in the Cr. japonica plantations was generally low, but some plantations were infested severely. The area of gallery of Co. formosanus in the stem decreased with height, and their galleries didn't extend upper than 50cm above the ground in stems where the termites did not construct a nest.
