Ryūchi Cave (龍地洞, Ryūchidō; Literally meaning "Dragon Ground Cave") is a legendary place that is equally as famous as Mount Myōboku and Shikkotsu Forest. It is the residence of the snakes — including the sacred White Snake Sage — and is also where Orochimaru uncovered the source of Jūgo's clan's abilities. Orochimaru and Kabuto Yakushi trained here to achieve Sage Mode, though only the latter was successful in this endeavor. Unlike the toads of Mount Myōboku, the snakes of Ryūchi Cave don't seem to have any affiliation with Konohagakure, despite at least two of their summoners originating from the village. Also, three of their snakes seemed to show no hesitation in destroying the village itself.
