Ryūchi Cave

is one of the big three unexplored sage regions, a legendary place that is equally famous as the other two, 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 endeavour. Unlike the toads of Mount Myōboku, the snakes of Ryūchi Cave don't seem to have any affiliation with Konohagakure, despite at least three of their summoners originating from the village. Also, three of their snakes seemed to show no hesitation in destroying the village itself.
