Samurai Country

The Samurai Country (武士の国, Bushi no Kuni) is a massive nation inhabited by the Samurai that spans outwards toward the west and north of the Five Great Shinobi Nations. It is a nation composed of various provinces, each ruled by a "general" (大将, taishō) that serves as the province's political and military ruler. They are constantly in a state of civil war, in which each province seeks to unify the country under their banner, while some seek to remain isolated.

Land of Iron
Normally estranged from the other provinces, the Land of Iron serves as the gateway between the Samurai Country and the Shinobi World.
