Barrier Ninjutsu

is the incorporation of barriers into technique. Essentially these techniques allow the users to manipulate barriers. The user can erect barriers that can be used to protect themselves or to trap an opponent amongst other various uses.

There are also several species of animals that make use of barrier techniques such as the Gourd Toad of Mount Myōboku which tiles the Barrier: Toad Gourd Prison. Barriers have also been incorporated into the form of tags for both offensive and defensive purposes.
