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.

Trivia

• Tobi used this technique in the one-shot manga Road to Naruto The Movie.
