Years passed, and the hearts of the two became sorely troubled. But then, at last, in the 96th month, Isanami entered her labour, and the deity Amateru was born.
He was born as the sun rose on the first day of the year kishiye, in the 125th branch of the 21st suzu. He was born in the shape of an egg: for when he emerged from the womb, he was still covered in an egg-like membrane. This was a source of wonderment and consternation to all around.
The nine stars known as the Ametokotachi heavenly deities were invoked for worship at the Ayuki shrine. At their centre was Ameminakanushi ("Lord of the Centre of Heaven"), the primordial creator deity, also called Amemiwoya. The other eight were the amoto deities To-Ho-Ka-Mi-Ye-Hi-Ta-Me. Meanwhile, the eleven earthly deities known collectively as Umashiashigaihikochi were invoked for worship in the Wasuki shrine. They were the five deities who protected the cardinal directions (east-west-centre-south-north), and the six Amiyashinau deities. Having reported Amateru's accession to these nine heavenly deities and eleven earthly deities, he now officially acceded to the throne with a full mandate from heaven, earth, and people.
