The Land of Rivers (川の国, Kawa no Kuni) does not play any particular role in the story until Pakkun discovers the first known Akatsuki hideout in one of the country's caverns, where Akatsuki extracted Shukaku from Gaara's body. The hideout was decimated shortly thereafter during a battle between Sasori, Sakura and Chiyo, and subsequently abandoned.
In the anime, this country also holds the Katabami Gold Mine, village, and processing centre. There is an exclusive shop renowned as the Curry of Life Shop where Naruto, Neji, Tenten, and Rock Lee came to eat. The Takumi Village and Tanigakure also reside here. Sometime after the Ōtsutsuki attack, a team of researchers from this country was sent to investigate Jūgo under the guise of looking into a recent spike in violent bird attacks.
