Tengoku, the Celestial Heavens is one of the known Spirit Realms. It is here that Amerterasu and Onnnotangu, Lady Sun and Lord Moon, the Fortunes and the Kami make their home. It is rare for any mortal to ascend to the Heavens, but it has happened. Most mortal’s spirits go to Yomi, the Realm of Blessed Ancestors. Tengoku is in conflict with Jigoku and that conflict usually plays out in Ningen-do.
