Ryūchi 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. Unlike the toads of Mount Myōboku, the snakes of Ryūchi Cave doesn't seem to have any affiliations with Konoha, despite at least two of their summoners originating from the village. Also, three of their snakes seems to show no hesitation in destroying the village itself.
