Yin–Yang Release (陰陽遁, In'yōton, Onmyōton) techniques make simultaneous use of Yin Release and Yang Release. Yin relates to one's spiritual energy and Yang relates to one's physical energy, and it's necessary to utilize both of these in order to mold chakra for ninjutsu. As such, the basis of simply kneading chakra and using techniques is based in Yin-Yang Release. Furthermore, Yin–Yang Release is suggested to be connected to Six Paths.
