The Yamanaka Clan is a family of shinobi found in Noharagakure. They specialize in mind related techniques, and they own and run a flower shop in the village. They traditionally lead the Nohara Barrier Team.
The members of this clan specialise in mind-related techniques which makes them experts at intelligence gathering, espionage and interrogation amongst other things. They have also displayed sensory abilities and their techniques include transferring their consciousness, reading minds and communicating telepathically. The flower symbol of this clan is the bush clover which symbolises a "positive love".
The Yamanaka clan has a special relationship with the Marocco clan and Nara clan. For generations, members of these three families have formed an trio, fighting together during battles. To strengthen the unity between the three clans, a member of the Uzumaki clan will give them special earrings to present to each generation head when they are promoted to chūnin after which they will swear their oaths. The earrings also symbolise that they are considered adults by their respective clans.
