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' daimyo by mistake. The Fang Daimyo, who was an Icha Icha fan, thought it was a gift from the Claw Daimyo and avoided the war.
