Tetsukage

The Tetsukage (鉄影; Literally meaning "Iron Shadow") are the leaders of Heiwagakure. They are generally the strongest shinobi in the village, although ideology and renown plays a large part in their being chosen for the position. Due to the age of the village, there have been so many Tetsukages that the numeric position of a kage is not as important as it is to other villages. They are usually referred to by name (ex. Tetsukage Hikaru)

First Tetsukage
Kouta Uchiha was Heiwagakure's first Tetsukage. Him and his wife Maiko Senju formed a secret activist group made up of Senju and Uchiha that's main goal was to bring peace between the two clan. When it was realized that an accord was not coming anytime soon, the group decided to leave their clans and recluse to the area that would become the Land of Iron.
