The user gathers a large amount of water and shapes it into a giant dragon before launching it at the target. While the technique can be performed by using a nearby water source as a medium, if the user is skilled enough, it can performed without one. The amount of water used will be in proportion with the user's skill.
When written as "水流", suiryū means "water current".
During this technique's first appearance, forty-four hand seals were used to perform it; the highest amount of hand seals necessary to use a technique shown in the series so far. Later appearances of this technique, however, have implied that the exact number of seals required isn't fixed.
