A technique that uses a crystal ball to track a particular individual anywhere they are. There are a few restrictions about the person that is subjected to pursuit. The user must know that person's chakra pattern. If someone can be targeted for pursuit, they may be very far away, the crystal ball will be able to confirm their position. As this technique is infallible for intelligence purposes, the Third Hokage used it to maintain public order in the village.
- In the movie tie-in specials Road to Naruto the Movie and Prologue of Road to Ninja, Obito used this technique to gather information for his Limited Tsukuyomi and used the ball to serve as a medium to cast and host the alternate world.
- In Naruto Shippūden: Kizuna Drive, Gensui also used this technique to control his false tailed beasts and to shoot spheres of energy.
