Uzumaki Clan

The was a prominent clan in Uzushiogakure. Although much is not known about the clan, most of its known members currently reside in Konohagakure, with the Fifth and Seventh Hokage being descendants of the clan.

Overview
The Uzumaki, being descendants of Asura Ōtsutsuki, also shared distant blood relation with the Senju clan. Through the years, the Uzumaki and Senju kept close ties, with members at times marrying between clans, as with Hashirama Senju and Mito Uzumaki. Following the founding of Konohagakure at the end of the Warring States Period, the Senju chose to symoblise their clans' friendship by adding the Uzumaki's emblem to Konoha's flak jackets. Konoha and the Uzumaki's own Uzushiogakure remained close allies over the following decades, with the Uzumaki providing fūinjutsu (among other things) to Konoha whenever there was a need. In time, the Uzumaki Clan's Mask Storage Temple was even constructed on Konoha's outskirts.

The Uzumaki's skill with fūinjutsu earned them both respect and fear throughout the ninja world. At some point after Kushina Uzumaki immigrated to Konoha, some of the world's nations banded together to destroy Uzushiogakure, believing the village was too powerful to be allowed to continue. The survivors of Uzushio's destruction went into hiding and spread throughout the world: Nagato was born and raised in Amegakure; Karin apparently lived in Kusagakure for a time; Kushina in Konoha had a son, Naruto, who years later has children of his own: Boruto and Himawari.

Abilities
Uzumaki naturally possess incredibly strong life forces, allowing them to live long lives; Mito Uzumaki was born before the founding of Konoha yet lived well into the reign of the Third Hokage. This also enables them to recover from injuries and exhaustion in short periods of time, enough to survive the removal of tailed beasts, although they are still left near death afterwards. Karin (and her mother in the anime) can seemingly harness and accelerate the Uzumaki's rejuvenative traits by biting her and sucking her chakra.

The Uzumaki were most famed for their fūinjutsu, the seal of which typically appears as a spiral crest reminiscent of the Uzumaki's symbol. Both Kushina and Karin have been shown producing Adamantine Sealing Chains made of their own chakra, but it's not known if this is common to all Uzumaki.
