Trivia

 * 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.
 * The full name of the historical and mythological Treasure is Yasakani no Magatama . A magatama is a curved jewel resembling a comma with a hole in the middle.
 * 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.
