Touch the mystery of nature in the lava tree molds cave

About 68m long Funatsu Tainai lava tree molds were created lava from Mt. Fuji 1000 years ago. A lava flow coated trees and burned the insides leaving lava shells. Inside the molds resemble the inside of a body, were considered a sacred site, where Fuji-ko adherents used to purify themselves and pray for safety before climbing Mt. Fuji. More than 60 tree molds scattering in this area, are designated as a natural monument in Japan.
