Kuriharu Clan

The Kuriharu Clan (くりはる一族, Kuriharu no Ichizoku)  is an minor clan at Iwagakure formed by blacksmiths and inventors of weapons and that after the creation of Ishigakure, it moved to the Land of Gravels. Although a minor clan, its importance to Iwagakure was big because the largest share of arms created for the village came from the clan's blacksmiths. Its fame also came from members who were able to perform the Kekkei Genkai: Land Release.

Migration to the Land of Gravels
The output of the Kuriharu Clan from the Land Earth and Iwagakure occurred because the daughter of the deputy leader of the clan, Niwa Kuriharu, be bride of the founder of Ishigakure, Daitan Futekina and have abandoned the village along with her fiancé. Thus, wishing to become a leader of a great expression clan in a new country, Tankō Kurihaku, a former leader of the clan and Niwa's father brother-in-law, faced Ishigakure as a beneficial opportunity for his clan, and thus didn't think much before leaving Iwagakure.
