Who is known as the "August Star of Heaven" in Japanese mythology?

Amatsu-Mikaboshi, meaning the "August Star of Heaven" is the god of evil and of the stars. specifically the pole star in Japanese mythology. Despite being mentioned in Eastern lore, the exact details and characterizations of Amatsu-Mikaboshi are very cloudy or unclear, as he (or it) is rarely if ever mentioned in any of the typically referenced texts of East Asian mythology.

Amatsu-Mikaboshi is a force of absolute domination that feeds off human emotions that, if left unchecked, result in social, emotional, or physical destruction. For instance, a desire for success can lead to greed and lust for power, which is the result of the influence of Mikaboshi's residue. Love for another can lead to obsession or jealousy, also result of its dark influences. In later centuries, certain creatures that are by nature dark or demonic were said to be connected to Mikaboshi in a sort of slave relationship to its power.
