The Land of Water (水の国, Mizu no Kuni) also known as the "Land of Mist" (霧の国, Kiri no Kuni). It is composed of many islands, with each having its own unique traditions. The country's weather is typically cool and the islands are usually covered by mist. The islands themselves also feature many lakes. In some places, like the area where Haku grew up, it is very cold and snows quite a bit. The nation is oriented towards the element of water. Its government leader is the Water Daimyō.
Little is currently known about the country and it apparently leaves itself out of most political affairs, which is understandable considering that it is composed of vast islands relatively remote from the continent containing the other four major countries. What is known, however, is that the country used to be ravaged by many civil wars, during which clans with kekkei genkai were used extensively, causing many to view them as harbingers of war and death, leading to purges and genocide to the point of parents killing their own children. Many clans went into hiding, such as the Yuki clan. Fifteen years after the Fourth Shinobi World War, the Land of Water grew uneasy with the Land of Waves and Land of the Sea over their continued expansion, to the point of not wanting to sign a treaty that would give them further stability, even against the wishes of Kirigakure, who would also benefit from more stability.
Main article: Kirigakure Kirigakure (霧隠れの里, Kirigakure no Sato, Literally meaning: Village Hidden by Mist) is the hidden village of the Land of Water. As the village of one of the Five Great Shinobi Countries, Kiri has a Kage as its leader known as the Mizukage, of which there have been six in its history. Befitting its name, the village is surrounded by a thick mist, with several mountains in the background, making it difficult to find by foreigners.
- In matters of land area, the Land of Water is undoubtedly the smallest of the five great nations.
- "Kirin Nectar" (麒麟蜜, Kirin Mitsu, English TV: Unicorn Nectar) is a regional speciality of the Land of Water.
