In Inuyasha, there seems to be a higher class of Yokai, where Inuyasha's father belonged, called "Dai-Yokai" (or "Great Yokai").
What qualifies you (the average Yokai) to be a Dai-Yokai? Are you born like it? Do you earn the status somehow?

Inuyasha wiki says the following about daiyōkai:
Most daiyōkai have long lifespans, possibly even longer than those of normal yōkai. They tend to remain calm in battle even if the situation is dire or their life is threatened. Daiyōkai vary in shape and size, just like normal yōkai. Some have, or are able to transform into, human-like forms, such as the Inu no Taishō and Sesshōmaru. Others, like Ryūkotsusei, are very large in size and don't at all resemble humans. Though it is not clear whether this applies to all Daiyōkai, it seems that some became feudal rulers over vast territories, commanding lesser demons. They sometimes wage war against other yōkai and humans alike.
About what qualifies one as such, is more controversial. It may be possible that it's both possible to be born like one, and to become one.
For example, Inu no Taishō's son from an unnamed demoness, Sesshōmaru, is a daiyōkai, and even Inuyasha, while being half-human, possesses power beyond those of an ordinary yōkai, so "being born with it" is plausible.
