Abstract
Mikura Island, a small island 200 Kilometers south of Tokyo city, is known for giant trees thousands of years old that grow there. The objective of this study is to examine the feature of water and soil environment in which the giant trees could grow up, and to look for the way we can do for the preservation of nature. The various chemical microanalyses are mainly carried out on the water, rain and soil. Based on the analytical results, the national environment in Mikura Island is discussed.
