This technique was designed by Tsunade for the purpose of sealing a tailed beast. The technique is performed with four separate scrolls and a sample of blood similar to a Summoning Technique. Shizune mentioned that good chakra control and concentration are needed to perform the sealing technique. To use this technique, a scroll is needed to seal the numerous amounts of chakra. This technique was supposed to seal the Three-Tails in its own dimension, permanently. This technique has three stages:

1. "Search"- the barrier is erected to locate the target.
2. "Bind"- the barrier is then stretched out above the target.
3. "Lock"- the barrier is lowered and the sealing begins.
