- Slope underworld boundary

Brief Bio 

The myth, which holds that there is a boundary place between the realms where the living and the dead reside, is an idea that is shared by the Sanzu River and others, and can be found throughout the world. In Japanese mythology, Yomotsu Hirasaka is thought to be an impression from the stone structure of kofun and the road leading to the stone chamber that housed the coffin.

In Kojiki, it appears twice in the upper part of the book, and there is a tradition that it is located at Ifuyasaka in Izumo Province.[1] The word "hira" is said to mean "cliff".[
