Formed in 937 AD when molten lava enveloped fallen trees on Mount Fuji's northern slopes, the Funatsu-Tainai lava tree mold is an intriguing natural tunnel steeped in sacred history. Its undulating, organic interior evokes the shape of a human womb, prompting centuries of Fuji-ko pilgrims to crawl through its depths seeking spiritual purification before ascending the holy volcano. Expectant mothers also historically journeyed here to pray for safe childbirth at the entrance shrine dedicated to the goddess Konohanasakuya-hime. Today, this quieter corner of the Mount Fuji World Heritage Site offers adventurous visitors a rare, tactile glimpse into Japan's ancient volcanic folklore.
