According to Kojiki, Ame no Minakanushi no Kami first came into being in Takamagahara (the Plain of High Heaven) at the time of the creation of heaven and earth (Japanese mythology), and then appeared Takamimusubi no Kami together with another kami called Kamimusubi.
古事記によれば、天地開闢(日本神話)の時、最初に天御中主神が現れ、その次にカミムスビと共に高天原に出現したとされるのが高皇産霊神という神である。
