Amano-Iwato

According to the Kojiki (Records of Ancient Matters) and the Nihon Shoki, the bad behavior of Susano'o, the Japanese god of storms, drove his sister Amaterasu into the Ama-no-Iwato cave.

[1] In order to get Amaterasu out of the cave, the other gods called Yao-yorozu-no-kami threw a party outside with wisdom of Omoikane.

Amaterasu grew curious about the source of amusement and peeked out of the cave entrance.

She became fascinated by her own reflection in the Yata no Kagami mirror which the other gods had crafted and hung before the cave for that purpose, and stood transfixed.

As Amaterasu stepped out of the cave, a holy seal was applied to it so that she could never go back into hiding.

The Takamagahara pantheon is thought to have gathered and discussed how to get Amaterasu out of the cave at this riverside, 天安河原 ( Ama no Yasugawara ) , at Amanoiwato-jinja in Takachiho , Miyazaki Prefecture .
