The "Three Wolves" mountains where the Land of Iron resides.
The Land of Iron is an icy, snow-covered country lead by Mifune. It is politically unusual in that has remained neutral and never been involved in the ninja wars. Despite this, it is said to have an incredibly strong military which, instead of ninja, is manned by Samurai.
The Kage Summit will be held in the Land of Iron due to its security and neutrality, which it has prepared for by strengthening it's guard. According to the Tsuchikage Ōnoki, it has it's own distinct culture, and there is "nothing fun about" meeting there.
