Japanese coastal pine forests have been suffering from pine wilt disease, and thus both disaster preventional and scenery functions might be declining. For the continuity and maintenance of coastal forests by way of pine seedling planting with bio-resources of symbiotic fungi, the project was carried out ectomycorrhizal community in the forests with morphological and genetic methods. Species diversity of ectomycorrhizal fungi was less than that from inland forest ecosystems. Imperfect fungi, Cenococcum geophilum was dominated as ectomycorrhizal roots of pine trees in all of study sites. These result indicated that ectomycorrhizal fungal community is simpler than inland forests.
