Space–Time Ninjutsu (時空間忍術, Jikūkan Ninjutsu, English TV: Teleportation Techniques, Literally meaning: Time–Space Ninja Techniques) are techniques that allow the users to manipulate the space–time continuum. By manipulating a specific point of space, the user can warp anything targeted into a dimensional void and teleport it to another location instantaneously. Minato Namikaze, Obito Uchiha, Tobirama Senju, and Kakashi Hatake are all noted as skilled users of space–time ninjutsu.
All summoning-based techniques are space–time manipulation related, as they warp the targets through a dimensional void to the summoner's location. It appears that each specific space-time technique has its own unique dimensional void that no other technique can access.
