Hitoana Fuji-ko Historical Site
A historical site on the site of the Hitoana Sengenjinja Shrine. Here you'll find the Hitoana lava cave formed by the Inusuzumi Yama lava flow as well as over 200 monuments arranged by the Fujiko Shinto devout. The lava cave, the center of the historical site, drops down to a depth of nearly 880 meters. In the Azuma Kagami, a history book compiled by the Kamakura Shogunate, it's stated that this is the residence of the goddess Sengen Daibosatsu, which suggests that the lava cave had a deep connection to the Fujisan faith in those days. It is currently only possible to enter a small portion of the cave where a small shrine, three monuments, and four stone Buddhas have been erected (advance application required).
