Regeneration of a mature mexed Fagus crenata-Fagus japonica forest on the Pacific side of Japan was studied on Mt. Mito, Okutama, west of Tokyo. From the structure of the forests, the regeneration pattern itself was similar to that of the beech forests on the Japan Sea side. In the mature stands two species of beeches (F.crenata and F. japonica) and Quercus mongolica var. grosseserrata were dominant, while in the younger stands Acer spp. and other canopy forming species prevailed. The density of F. crenata seedlings was quite low as compared with the beech forests on the Japan Sea side, indicating that F. crenata is declining. The species composition of the forests seemed to change from the dominance of two beech species with Q. mongolica var. grosseserrata to a co-occurrence of various deciduous species with a slight dominance of F. japonica and Acer spp.
