Mt. Fukino is a 550-meter-high mountain that rises near the boundary between Matsuzaki and Nishi-Izu towns, northeast of Matsuzaki City, along with Mt. Chokuro in Amagi. Located at the top of the mountain, the Soto School Fukino Mountain Treasure House is an ancient temple opened by Kukai (Kobo Daishi) in the 3rd year of Datong as a sacred place for esoteric Buddhism, and was originally called Fukino Jizo Secret Temple. In the Muromachi period, it flourished as a large sacred site with 88 temples, but after that, it was deserted and rebuilt by the monk Iwanaka. In the Bunki year (1501~04), the 4th generation monk Kiyoyasu of Kawazu and Fumon-in converted from Shingon Buddhism to Soto School, and from this time on, it became Hozoin. In the precincts, the largest cedar in Minami-Izu (circumference 6.5 m, height 34 m), which is estimated to be about 400 years old, and Oshima cherry trees that are 150 years old are densely grown, and it is rare to see more than 180 "wild Buddhas" lined up around the approach. Dainichi Nyorai, Yakushi Nyorai, Amitabha Buddha, Jizo, Kannon, Kobo Daishi, etc., all of which look like mossy stone Buddhas, seem to be singing a chorus of heartlessness in the human world. It is also the 7th sacred site of "Izu Yokodo 33 Kannon".
