Summary
There are stories of hunters wandering into the deep mountains, arriving by chance, hearing weaving and rice making in the mountains, and chopsticks and bowls flowing from the top of the river. The residents live peaceful lives without conflict, and the climate is warm, and visitors from outside spend pleasant days with kind hospitality, but even if they try to visit again, they will never be able to visit again. In the background of such tradition, the existence of a village where Heike's fallen people are said to have lived in hiding, and there are villages that are actually said to be heike valleys and heike hideaways. In addition, it can be inferred that the simple mountain worship and the idea of the utopia before the introduction of Buddhist Pure Land thought are influenced. The hidden village is a separate land that is imagined to be deep in the mountains, in the mound hole, and in the far upper stream of the river, and at the bottom of the abyss. It is said that it is a Hinden Hyakushomura, but the hidden village is a peaceful world without any sorrow, and there is a flow at times different from the human world. Ordinary people can't go there, but good people sometimes have a chance to get a glimpse of the world.[1] In any case, Eiko Arima, a member of the National Society of Japan, said that the people's desire for a utopia was put in place.
