Otogakure (Otogakure no Sato, Literally meaning: Village Hidden by Sound) was the personal hidden village of Orochimaru, which was founded for the express purpose of collecting ninja for his experiments and his quest to learn all techniques. In actuality, Otogakure is not really a village, but a giant laboratory composed of various hideouts and bases scattered throughout the Land of Sound and various other countries. Otogakure' s shinobi use a diverse number of techniques, which are mostly centered around the modifications resulting from Orochimaru' s human experimentation.
