Shikantaza

Considered a very simple, but effective, technique, Gyouzen (凝然; Literally meaning "Frozen in Place") is Ichida's signature technique.

Overview
The user gets within close range to the target. Once close, the target must look into the user's eyes, paralyzing them afterwards. What this technique also does is link the user and the opponent's chakra together so that the user can replenish their own chakra reserves as well. The genjutsu only last at least 10 seconds but the chakra link remains unless it is severed.

Ichida's use of the technique allows him to completely absorb all of the opponent's chakra with one glance.
