Jofuku forest.
The Jofuku Forest (徐福の森, Jofuku no Mori, literally meaning: Gradual Good Fortune Forest) is a location on Mount Jofuku on the border of Land of Fire. It is known for Jofuku flower, which is used for medicine purpose. An old lady from the nearby village said that the forest is haunted. Furofuki lives in the forest inspecting the flower. Naruto, Sakura and Ino were sent to the forest to deliver a message to Furofuki from Tsunade, telling her to give them the Jofuku flower so Might Guy could make a medicine for Rock Lee. This forest is known as the Lost Forest.
