Epiphytic cyanobacteria were observed on the moss communities growing in the alpine zone of Mt. Fuji (3776 m alt.). Nitrogen-fixing activities of these cyanobacteria were investigated by the acetylene reduction method. Weak or no nitrogen-fixing activity was detected for moss communities growing in the xeric habitat on the southwestern slope. The dominant cyanobacteria in these moss communities were Stigonema minutum and Gloeocapsa magma. Nostoc sp. was also observed for some communities. Moss communities growing on the moist northeast-facing cliff showed high nitrogen-fixing activities. Nostoc sp. was the dominant epiphyte on these moss communities. These moss-cyanobacteria associations were similar to those of the continental Antarctic in several points.
