The Nara clan's forest.
This forest is a large expanse of land owned by Konohagakure's Nara clan. Located on the outskirts of Konoha, it is a unique forest within the Land of Fire. Many deer reside here as the clan looks after them and often times use their antlers in medicines, one such being the remedy to the Akimichi clan's Three Coloured Pills. According to Shikamaru Nara, no one but members of the clan are allowed to step foot into the forest without permission.[1]
The Akatsuki member Hidan — though currently still alive — is buried here, trapped in a grave made for him by Shikamaru. As he buried him, Shikamaru swore to Hidan that the Nara would keep him buried there for all eternity.[1] In the anime, Kabuto Yakushi was able to sneak into the forest and collect some of Hidan's DNA for later use.[2]
