Main article: Chidori

- Hand Seals: Monkey, Dragon, Rat, Bird, Ox, Snake, Dog, Tiger, Monkey, or Ox, Rabbit, Monkey
- Users: Kakashi Hatake, Sasuke Uchiha
Chidori ("One thousand birds") is the only technique (in Part I) in Kakashi's arsenal that is his original creation. It was created as an alternative to adding lighting manipulation to Rasengan, which Kakashi failed to do. The user channels a large portion of lightning-chakra to the hand. The concentration of electricity formed produces a sound similar to that of birds chirping, hence the technique's name. The user will then quickly charge and lunge the technique into the target for a usually fatal blow. Since Chidori is performed at high speeds, it has been classified as an assassination technique despite the loud noise it makes.
Although the technique itself is formidable, the manner in which it is used is impractical and can even pose a threat to the user. The speed required for its use in combination with the fact that the user must charge in a straight path makes it easily subject to a counter-attack. Having the Sharingan, Kakashi and Sasuke are able to avoid this drawback due to their heightened visual perception. Sasuke, over the course of his training with Orochimaru, has developed several variants of this technique using shape manipulation.
Main article: Raikiri
- Type: S-rank, Offensive, Short range (0-5m)
- User: Kakashi Hatake
- Hand Seal(s): Ox, Rabbit, Monkey
Raikiri (lit. "lightning blade") is a stronger variant of Chidori used only by Kakashi. It earned its name through rumors saying that Kakashi once cut through a lightning bolt using the technique. The technique is formed and used in the same manner as Chidori, but differentiates in the damage that it causes, thus being classified as a S-ranked technique rather than Chidori which is an A-ranked technique. Though there are no visual discrepancies between Chidori and Raikiri, Kakashi will often correct someone if he/she refers to his technique as Chidori.
