Sand Coffin jutsu

The Sand Coffin jutsu is a technique that is unique to Gaara. Using his gourd sand, also increasing the amount at times, Gaara encases his opponent with sand, immobilizing them and, if he so desire, suffocating them. This jutsu is always used in combination with Gaara's Sand Burial jutsu to crush his opponent to death as part of his "catch and crush" tactic. It has a larger variant called Sand Tsunami.
