Yomotsu Hirasaka is a pathway in Japanese mythology connecting Yomi with the human world.
This place is somewhat similar to the Road to Yomi in Chinese mythology, but it is not the entrance to Yomi; it is the exit from Yomi.
Moreover, this place was blocked by Izanagi with the Senzui Stone in ancient times, separating Yomotsu no Oni Kuni from the human world, preventing any ghosts and monsters from Yomi from entering the human world, and also keeping mortals from entering Yomi.
Although this place is the boundary between the human world and Yomi, it does not exist in the present world. But since it connects the human world and Yomi, naturally it can be entered from the human world into Yomotsu Hirasaka.
And the place to enter Yomotsu Hirasaka from the human world is what is now Shimane Prefecture, Japan, also known in Japanese history as Izumo Province.
