Youkai or Yokai.

Yokai are a diverse class of spirits and demons in Japanese folklore. They often manifest as distortions or exaggerations of natural phenomena or human characteristics. These beings can be found in various forms, from shape-shifting foxes to grotesque giants. While some yokai are mischievous, others can be quite dangerous.

Culture

Yokai are deeply rooted in Japanese culture, representing the fears, hopes, and beliefs of the people. They are often depicted in art, literature, and film, and have evolved over centuries to reflect changing societal values. Encounters with yokai are frequently used to explain unusual events or to teach moral lessons.
