Land of Water

is oriented towards the element of water. Its government leader is the Water Daimyō. It is composed of many islands, with each having its own unique traditions. The country's weather is typically cool and full of mist and lakes. In some places, like the area where Haku grew up, it is very cold and snows quite a bit. Little is currently known about it 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.

is a regional speciality of the Land of Water.
