YomiYomi or Yomi-no-kuni is the Japanese word for the land of the dead (World of Darkness). According to Shinto mythology as related in Kojiki, this is where the dead go in the afterlife. Once one has eaten at the hearth of Yomi it is (mostly) impossible to return to the land of the living. Yomi in Japanese mythology is comparable to Hades or Sheol and is most commonly known for Izanami's retreat to that place after her death. Izanagi followed her there and upon his return he washed himself, creating Amaterasu, Susanoo, and Tsukuyomi-no-Mikoto in the process.
Nihon ShokiThe Nihon Shoki, sometimes translated as The Chronicles of Japan, is the second-oldest book of classical Japanese history. The book is also called the Nihongi. It is more elaborate and detailed than the Kojiki, the oldest, and has proven to be an important tool for historians and archaeologists as it includes the most complete extant historical record of ancient Japan. The Nihon Shoki was finished in 720 under the editorial supervision of Prince Toneri with the assistance of Ō no Yasumaro and presented to Empress Genshō.
Izanami, formally known as Izanami-no-Mikoto, is the creator deity of both creation and death in Japanese mythology, as well as the Shinto mother goddess. She and her brother-husband Izanagi are the last of the seven generations of primordial deities that manifested after the formation of heaven and earth. Izanami and Izanagi are held to be the creators of the Japanese archipelago and the progenitors of many deities, which include the sun goddess Amaterasu, the moon deity Tsukuyomi and the storm god Susanoo.
IzanagiIzanagi (イザナギ/伊邪那岐/伊弉諾) or Izanaki (イザナキ), formally known as Izanagi-no-Mikoto, is the creator deity (kami) of both creation and life in Japanese mythology. He and his sister-wife Izanami are the last of the seven generations of primordial deities that manifested after the formation of heaven and earth. Izanagi and Izanami are held to be the creators of the Japanese archipelago and the progenitors of many deities, which include the sun goddess Amaterasu, the moon deity Tsukuyomi, and the storm god Susanoo.
