Very little is known about the Eastern Hideout (東アジト, Higashi Ajito) but it was also built underground. This was where Orochimaru in one last failed attempt, tried to take over Sasuke Uchiha's body. Sasuke, however, was the one to take over Orochimaru's body instead. It was also filled with large glass cylinders with liquids in it. Here was where Suigetsu Hōzuki was kept and experimented on until Sasuke Uchiha freed him from confinement.
