Hitoana Fuji-ko Iseki

Hitoana Fuji-ko Iseki is a sacred cave formation on Mount Fuji that penetrates deep into the mountainside. Inside, a central volcanic pillar rises through the space, with religious structures and stone objects arranged throughout the cave.

In the 16th century, religious leader Kakugyo performed ascetic practices in this cave and made it central to the Fuji-ko movement. The location later became a pilgrimage site, drawing followers who wanted to practice the spiritual methods he established.

The grounds hold 233 memorial stones placed by Fuji-ko followers between the late 18th and early 19th centuries. These stones show how central this location was to the spiritual lives and shared beliefs of the community.

The site is reached by hiking paths that are easiest to navigate during warmer months. Visitors should wear sturdy footwear and check current conditions, as the cave itself is not open to enter due to safety concerns.

The cave holds three memorial towers and four stone Buddha statues arranged together with a shrine inside. These objects were added over generations by devoted followers and remain visible reminders of sustained spiritual practice.
