Uzamaki Kushina's technique comes from inside Naruto to bind the Nine Tails. A characteristic of the Uzamaki Clan is powerful Fūinjutsu. Chains are released and the opponent is bound head to foot, moving about is sealed. The chain's, strong point, is how overwhelmingly sturdy (durable basically) they are, the Nine Tails was quickly suppressed. It was this power that made the Jinchūriki Kushina the perfect seal for the Nine Tails. Uzamaki Karin's technique only shows a mere glimpse of this technique (Basically Karin's technique is a glimpse of this technique's true ability, and I guess that's why Karin was not listed as a user)
