Land of Waves
The Land of Waves (波の国, Nami no Kuni) is a relatively poor nation, and thus does not have a hidden village, however when it was the Land of Whirlpools it used to have one. It is an isolated island, but used to be prosperous nonetheless, until Gatō set his sights on it. He broke the people's will and monopolized the shipping industry, which was crucial for its economy. Team 7's first real mission was to this country, and, with the help of Zabuza Momochi and the townspeople, Gatō's reign of terror was ended for good. Afterwards, a bridge was built to connect the country to the Land of Fire. After the construction of the bridge, commerce and trade increased bringing more revenue to the Land. It is now a prosperous area.
Sasuke Uchiha briefly visits the country in Part II, bringing Suigetsu Hōzuki with him to retrieve Zabuza's Decapitating Carving Knife.
