Land of Predators

The Land of Fangs (牙の国, Kiba no Kuni) 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.

History
There isn't much known about the Land of Fangs other than at one point it almost went to war with the Land of Claws before defusing the situation after one tiny mistake with a Icha Icha book. It was later revealed that the Unubore Jungle is located in this country.
