The Tree of Rebirth is a hidden sacred tree cultivated under the authority of Enma-ō, the judge of the dead in Japanese Buddhist tradition. Unlike widely known sacred trees such as the Goshinboku or the Tree of Ages, the Tree of Rebirth is not part of public myth, worship, or legend. It exists as a secret failsafe, created for rare cases where the normal cycle of death, judgment, and reincarnation cannot properly proceed.

The Tree governs neither life nor death directly. Instead, it governs continuation. It allows souls that should have ended, but cannot, to persist in a new form. This is not resurrection in the common sense. It is not mercy. It is correction.

Among gods and high-ranking yōkai, the Tree is considered Enma’s most private domain. It is spoken of rarely, and only when absolutely necessary.
