Tsurugi Clan

History
It is a break off of the Yama Clan. Like the Yama Clan, it was a clan that originated in the Land of Mountains. They are very powerful Earth Jutsu users. They have a Clan Leader instead of a Clan Council. When Itachi, Sasuke, Ryun Uchiha created the Village Hidden in the Mountains they moved in and established their base in the village.
