The myth of the origin of the Japanese nation begins with sex and love. The natural god in historical legends is closely related to human nature, and God is also the desire of some people. The ancient Japanese worship of sex was combined with the worship of God, and their worship of sex was very frank and serious. For example, Xie Yiqina and Isobo Er Shen, men and women described in Historical Records and Riji, fell from the sky and saw a pair of pigeons kissing, so they also learned to kiss; I was even more excited when I saw a couple mating.
Xie Yiqina male god asked, "How is your body?" The goddess Isobo replied, "My body has gradually become complete, except for one place that is not closed." Xie Yi Zener said, "I still have room in my body, so I'll give it to you (referring to my penis)!" " Isobo agreed, and the couple enjoyed sex to the fullest. Goddess and goddess naturally merged into one, and finally eight million gods such as Japanese islands, mountains, rivers and plants were born. Xie Yi Na Zhi also gave birth to the Sun Goddess (the God of Heaven and Earth), who was in charge of the islands and everything in the world. The sexual union of two gods is called "God Marriage", which has been passed down from generation to generation. Japanese gods can enjoy love and sexual pleasure calmly, and there is no sexual taboo based on religious reasons.
In Japan, "convex and concave" refers to male and female reproduction, and also refers to sex. The word comes from the combination of Xie Yi Zener and Xie Yi Nami. It is sacred, but not obscene. Therefore, some Japanese people take "convex and concave" as their surnames, and some shrines are also named after "convex and concave". There are many objects of sexual worship on display in the shrine. There was also a saying in ancient China, "Why should I be convex and why should I be concave?" ? It is beautiful to try concave with convex, but it is not as emphasized as in Japan.
Another feature of Japanese primitive belief is the worship of genitals, which has a very long history. Stone sticks symbolizing male genitalia and female sexual organs protruding from clay dolls can be found in the ruins of the rope-writing era (from the eighth century BC to the fourth century BC). In the Yayoi period (4th century BC to 4th century AD), in the sacrificial ceremony of farming, sexual organs became the symbol of agricultural productivity and the object of worship.
Of course, people worship not only human organs, but also many symbols of sexual organs, such as natural stones shaped like male roots and female genitals. People think it is natural, so it has more magical power. This kind of worship exists in many places in Japan, some on the roadside, some in shrines or gardens. Up to today, there are still a large number of small and medium-sized cities in Japan, which are called "yin and yang stones" or "convex and concave stones". This is rare in China. Many Japanese gods show their genitals. The male god shows the roots of men, while the goddess shows the genitals of women. Later, the gods of this goddess gradually evolved into a Japanese-style "Guanyin". In Japanese mythology, there is also a Yin-deficiency god named Ape Tian Gu Kun, which symbolizes exuberant vitality. (Liu Dalin: Japanese god of childbirth)
