THE CLANS
A clan (一族, Ichizoku; Literally meaning "family"), in the loosest sense of the term, refers to a family or group of shinobi who form a basic unit of a shinobi village. Majority of these clans were mercenary military forces even before the First Shinobi World War. The Senju clan and Uchiha clan were the first known clans to have agreed to settle and form a shinobi village, facilitated by creating agreements with the daimyō of the land they inhabit. Many clans would follow the example of the Senju and the Uchiha, later establishing the Five Great Shinobi Countries as they are known today.
Membership in a clan is usually determined by blood relations and genetics, which is vital in the usage of kekkei genkai and secret techniques.
Aburame Clan - one of the four noble clans of Konohagakure. At birth, members of this clan are offered to a special breed of insects such as kikaichū as a nest, residing just under their host's skin. These insects will then live in symbiosis with their host from that point on. Because of this, its members are characterised by their use of insects as weapons.
Akimichi Clan - one of the four noble clans of Konohagakure.
