Ectomycorrhizal fungi are known to play an important role in the ecosystems of forests. However, their ecological aspects have not been demonstrated clearly because of the difficulties of long-term fieldwork in a forest. In the present study, the occurrence of sporocarps of ectomycorrhizal fungi was recorded for 20 years in the several different coniferous forests on the mountainside of Mt. Fuji and their quantitative, qualitative changes were analyzed in relation to the age of trees that composed the forests. In the north slope of Mt. Fuji, various coniferous forests are observed between 1,700m to 2,300m above sea level. Three experimental plots (two rectangular plots of 4 m x 50 m and one square plot of 20 m x 20 m) were fixed in two natural and two planted forests of Larix kaempferi, two natural forests of Abies veitchii-Abies mariesii, three planted forests of Abies veitchii, and three natural forests of Tsuga diversiforia for field investigations, respectively.
