Gaki (Japan)

Gaki are the Japanese counterpart of e gui. They are ghosts of individuals who committed grave sins linked to greed and extreme parsimony. They were once humans who refused to share anything they owned, even with those in dire need, despite having the means to help. These individuals were critical of any acts of charity and benevolence.

Following death, they are reincarnated as gaki—eternally tormented ghosts, cursed with insatiable hunger and thirst. Gaki are depicted as ugly humanoids with sorrowful, anguished expressions. Their bodies are emaciated, save for their massive bellies.
