Obito's Laboratory

Tobi's laboratory is located within the Mountains' Graveyard headquarters of the Akatsuki. It was first seen when Tobi teleported himself and Danzō Shimura's corpse there in an attempt to retrieve Shisui Uchiha's eye only to discover that the elder had crushed it before his death — an action which Tobi cursed him for. This was also where Tobi transplanted Itachi Uchiha's eyes into Sasuke.

A massive wall decorated with the Uchiha clan symbol stores a large collection of Sharingan eyeballs, which are suspended in fluid inside built-in labeled glass containers. The laboratory is also equipped with an operating table for surgical use lying opposite to the Sharingan repository.
