This sealing technique completely blocks the target's chakra with a sealing formula (封印式, fūin-shiki) drawn on the ground or a wall. This is done by closing all the tenketsu of the person caught in the middle. When the target is sealed, a stylised kanji for "close" or "shut" (閉, hei) appears in the middle of the sealing formula.

To successfully seal the target, one has to get them exactly inside the sealing formula. This requires great accuracy and is very difficult. Various methods can be used to make this easier. For instance, one can prepare a puppet or a ninja tool like the Lion-Headed Kannon with this sealing formula.
