Land of Birds

From Narutopedia

The Land of Birds (鳥の国, Tori no Kuni) is a small country located between the Land of Wind and the Land of Earth. In the anime, Naruto, Neji, and Tenten were sent to country to investigate the rumor of the ghost of Cursed Warrior, as well as protect the daimyo, Sagi. They eventually learned that a group of wandering ninja called the Watari ninja was hoping to take over the country through a complex conspiracy. These ninja were defeated in the end. This land gets its name from the large number of birds that migrate to it each year.
