Land of Fangs

is featured in episode 177 of the anime. There was, at one point, tension between this nation and the Land of the Claw. The two sides barely averted a war thanks to Jiraiya's Icha Icha novel, which was delivered to the Land of the Fang's 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.
