"Jinchūriki Confinement!!" (人柱力監禁!!, Jinchūriki Kankin!!, Viz: The Jinchūriki, Detained!!) is chapter 491 of the original Naruto manga.
Summary[]
Naruto returns to the Ramen Ichiraku. Two Konoha ninja ask for his autograph, but he doesn't know how to respond. Three days later the Kage meet again to discuss how they should start pooling their resources. As the first matter of business, Naruto and Killer B are to be given constant protection. Tsunade objects since they would both be invaluable in the war with Akatsuki, but is forced to agree. Naruto and B are sent to a secret island in the Land of Lightning, the only country that has yet to have any connections to Akatsuki. Naruto witnesses B's control over the Eight-Tails firsthand soon after arriving, and decides to seek his help in taming the Nine-Tails.
