Yin–Yang Release

The 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. According to Yamato, the manipulation of Yin and Yang is the source of non-elemental jutsu such as the Shadow Imitation Technique, Multi-Size Technique, medical ninjutsu, genjutsu, etc.

The Sage of the Six Paths had such a mastery over the Yin-Yang Release that he was able to create Izanagi. He used Yin to make his dreams take form, and then used Yang to make his fantasies real. He could even make them come to life. According to Madara Uchiha, the Sage used Izanagi to create the tailed beasts out of the chakra from the Ten-Tailed Beast. Nagato also had mastery of the Yin-Yang Release, as well as all other elements at age 10, which was completely unprecedented.
