Among the 300 species in the Orchidaceae that have been shown to grow in the Japanese Archipelago, more than
110 have been identified in the Mt. Fuji region. Mt. Fuji, located at 35.4 ° N, is a globally unusual site of high orchid
species diversity. The reason for this is the existence, under a humid climate, of eight botanical zones, namely: the oak
zone, chestnut zone, beech zone, Abies homolepis zone, Abies veitchii zone, Larix kaempferi forest limit, herbaceous
zone, and moss zone, from the lowland to the mountain crest at an altitude 3776m. In the present study, the negative and positive effects of various human activities, such as theft, arable and pastoral land use, second-home construction, and artificial afforestation in the Mt. Fuji region over a 76-year period from 1945 to 2021, on orchids were evaluated based on species. This present study is the first report on 31 unique species, including the endangered Cypripedium species, saprophytic orchids named after Mt. Fuji. In addition, the following were discussed in relation to Cypripedium species: status of theft since 1945, actual and current growth status, appropriate nature protection activities, and proposed conservation measures.
