Uzushiogakure

was the shinobi village of the Land of Whirlpools. Its ninja were renowned for their fūinjutsu to the point that it led to its destruction in war. Those who survived the village's destruction scattered across the globe. The people of Uzushiogakure were noted to have notoriously long lives, so it gained the epithet.

In terms of appearance, the village seemed to have been composed of several cylindrical buildings, similar to those of Kirigakure. A wide river seemed to cut through the village and was gapped by large bridges. The surrounding countryside was dominated by steep hills.

Uzushiogakure had close ties with Konohagakure, due to Uzushio's Uzumaki clan and Konoha's Senju clan being distant relatives. Because of this, all chūnin and jōnin vests of Konoha shinobi bear the crest of Uzushiogakure, symbolizing the strong friendship that resided between both villages.
