The Land of Iron (鉄の国, Tetsu no Kuni) is an icy, snow-covered country. It is politically unusual in that it has remained neutral and never been involved in the ninja wars. In fact, the shinobi have a rule since long ago that they would not meddle with the land. Despite this, it is said to have an incredibly strong military which is manned by samurai, instead of ninja.

The Land of Iron, is the country home to Jiseigakure no Sato. Economically, it is a very important country as it shares it's borders with no less than four other shinobi nations. It is bordered by the Land of Cloud to the north, the Land of Gas and the Land of Ice to the west. In addition to those nations, it is bordered by the Land of Light to the east. It has provided a trading route for these other nations over the years. When war breaks out, Jisei-nin often act as pseudo peacekeepers and always try to end the war, with defeat to neither side. Generally speaking it is quite a rich shinobi nation.
