Water Prison Technique

This jutsu is used to trap a victim inside a virtually inescapable sphere of water. The only downside to this technique is that the user must keep at least one arm inside the sphere at all times in order for the victim to remain imprisoned. Clones can be used in place of the actual person, provided that the clone is the one that performed the technique. This jutsu can't be performed without a sufficiently large body of water to supply the water for it. Neji Hyūga has been able to use his ability to release chakra from all of his pressure points simultaneously to disrupt the flow of chakra inside the prison and break free.

It appears to be two versions of this technique, one to keep a prisoner safe inside a air filled sphere of water and one where it doesn't matter. Zabuza used the first on Kakashi, allowing Kakashi to move, breath and talk as normal. Kisame used the second version on team Guy, trapping them into a sphere of water, leaving them to drown.
