Takigakure (滝隠れの里, Takigakure; Literally meaning "Village Hidden in a Waterfall") is located in an unnamed country. In terms of the village's appearance, Takigakure seems to be based on mostly Southeast Asian aesthetics. Their current leader is Shibuki. The ninja of this village seem to specialize in water-based jutsu. It is shown to be built around a large tree. It also, predictably, has a waterfall as a defining landmark.
