There are a few clans who naturally have more affinity to it than others, like the Akimichi and Uzumaki clan who, respectively changes the size of their bodies and have incredible regenerative abilities. The Sage of Six Paths, Hagoromo Ōtsutsuki used Yin Release and Yang Release to create Yin-Yang Release, which allowed him to split the Ten Tails into the nine tailed beasts.
