Ame-no-Nuboko

[1] According to the Kojiki, Shinto's genesis gods Izanagi and Izanami were responsible for creating the first land.

[3][4] Yamato Katsuragi Hozan-ki, the Shinto book of Shugendo, explains that Amenonuboko is a mystical object generated at the time of the creation of heaven and earth, which is an incarnation of Bonten, and that it is regarded as a vajra which has a power to smash the evil and has another name Amanomagaeshi no hoko.

The Shinto book further explains that Ninigi, the sun goddess's grandson who descended to earth, is a deity of a vajra or a mallet decorated with gems, and that he is 天杵尊, also known as Kidoku-o, who has pacified the land using the mallet as a weapon.

Being influenced by these Shinto books, "Senguin Himon" describes that the grandson of the sun goddess descended from heaven carrying a sacred treasure Amenonuboko.

Other legends describe that Amenosakahoko was thrown down from heaven by Amaterasu or was transferred from Okuninushi to Ninigi.
