The most famous episode about Omoikane is that at the time of Iwato-gakure (the hiding of Amaterasu Omikami, the sun goddess, in the heavenly rock cave), Omoikane gave Yao yorozu no Kami (eight million gods) who gathered at Ama-no-Yasuharae the wisdom to let Amaterasu go outside the rock cave.
最も有名なエピソードは岩戸隠れの際、天の安原に集まった八百万の神にアマテラスを岩戸の外に出すための知恵を授けたことだ。
