Cooperation Ninjutsu

, called in the anime, is the combination of two or more  jutsu  to create a new jutsu with a strength greater than the sum of its components. This "strength" can be measured in terms of the new jutsu's range or destructive power.

Cooperation ninjutsu are little-explored in the series. Although there are numerous examples of characters working together and/or jutsu being performed in combination, Kiba Inuzuka's partnership with Akamaru being a prime example, these are never labelled "cooperation ninjutsu" and do not seem to exactly fit the definition. The few explicit examples are typically combinations of nature transformations, where one nature is used to make another nature even stronger, such as the Scorch Release: Halo Hurricane Jet Black Arrow Style Zero, a combination of fire and wind.

The anime explores cooperation ninjutsu during the Three-Tails' Appearance. During the arc, Jiraiya states that cooperation ninjutsu requires synchronisation between those whose jutsu are being combined. This synchronisation can be achieved either through familiarity with each other or mere like-mindedness. For example, because both Naruto Uzumaki and Gamatatsu are "simple", they are ideal collaboration partners.
