This defensive jutsu creates a wall of water around the user. Enemy attacks are completely intercepted by a fence of water blown out from the mouth, and is raised from below with tremendous might. The water is blown out in the form of a circle around the user, and it makes for a defence without openings. It is also possible for the user to control the amount of water and duration at will. The wall's strength and resistance change following the quantity of chakra poured down into the water, so a skilful shinobi will be able to build a sturdy one. Furthermore, because the field of vision is maintained even while defending one can easily go on to the next move, which is a great advantage. The wall can also be formed from a pre-existing water source.
Tobirama Senju was able to produce one without a pre-existing water source, which was a testament to his skill and one of the reasons why he was selected as Hokage. In the manga the hand sign sequence for this technique ends in the same seal that activates the Byakugan, though Tobirama only needs one to use this technique. Furthermore, the anime creates a completely original and far more elaborate set of hand seals when Tobirama uses it in the form of having the right hand cupping the left hand with a thumbs-up.
