Land of Fangs

is featured in episode 177 of the anime. There was, at one point, tension between this nation and the Land of Claws. The two sides barely averted a war thanks to Jiraiya's Icha Icha novel, which was delivered to the Land of Fangs' daimyō by mistake. The Fang Daimyō, who was an Icha Icha fan, thought it was a gift from the Claw Daimyō and avoided the war. This land is seemingly marked by numerous steep peaks, probably leading to its name.
