Amaterasu-ōmikami means "the great august kami (deity) who shines in the heaven." Why is it specifically august? What does the goddess name meaning august mean?
- Re: Why "august"
I'm not finding anything on Amaterasu referencing mortal beginnings, so we can probably discard the Roman association with deified rulers, and focus on the literal meanings of the term "consecrated, sacred, reverend, venerable, majestic, magnificent, etc."
