Mitama (みたま) is one of Amaterasu's three sacred treasures.
Mitama has lightly colored hair that is parted in the middle and cut into a straight bob. He has one dark eye and one pale eye.
Mitama is loyal to Amaterasu and Heaven. He is capable to remaining calm and stoic even while awaiting judgement during the covenant ritual.
- Historically, the Three Sacred Treasures of Japan were symbols of the emperor's divine right to rule over Japan. The three items are a jewel, a mirror, and a sword. Mitama represents the jewel, as "tama" can refer to a spherical gem. The other sacred treasures used by Amaterasu, Mikagami and Mitsurugi, represent the mirror and the sword, respectively.
- Mikagami as one of the Three Sacred Treasures can reincarnate, but in a different way from the gods.
- The names of the Three Sacred Treasures, Mitama included, are written using hiragana. This sets them apart from other shinki in the series, whose names are written using kanji only.
