This research field trip was organized together with my seminar students in order for them to study the cult of Mt. Fuji. This field trip included visits to Fuji Yoshida's main temples and shrines associated with the cult of Mt. Fuji, the museum of cultural history at Fuji Yoshida, and a visit of the "胎内 cave" at the start of the historical pilgrimage road of ascent to Mt. Fuji's summit.
