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. This is where the sacred White Snake Sage resides and where Orochimaru uncovered the source of Jūgo's clan's abilities. Orochimaru and later Kabuto Yakushi trained here to achieve Sage Mode.
