Tell the truest history in the simplest words.
As a "small country", Japan's development was relatively closed in its ancient times because it was surrounded by the sea on all sides. If closed on an individual, it can only bring about a distortion of personality, and to a large extent, it is also true, so "Shintoism" was born in Japan, which is a religion inherent in Japan.

Shintoism
Since Shintoism is an inherent religion in Japan, the Japanese regard it as "the essence of the country", and "Shinto" means "worship of God". It originated in the nature worship, ancestor worship and witchcraft of Japanese clan society, and after the confrontation between "Shintoism" and "Chinese Taoism", it was deeply aware of its own shortcomings, so it absorbed the part of Chinese Taoism that was beneficial to itself and developed into a "Japanese-style" religion centered on the emperor.
The term "Shinto" first appeared in the Japanese Shogi compiled in 720 AD. Early Shintoism, reflecting the ancient pantheistic ideas, worshipped a variety of gods, believing that There were "8 million gods in heaven and earth" in Japan. Not only do all things such as plains, mountains, flowers, trees, and other things have "spirits", but there is no obvious boundary between gods and people, so outstanding people are often worshipped as gods. If we look back at some of the movie plots, we will find that the ancestors of the Japanese people were often deified, and it was precisely because of this influence.
When Buddhism was introduced to Japan, the Japanese rulers once again absorbed the contents that were beneficial to Shinto, forming the "Two Shinto", "Shingon Shinto" and "Hokke Sutra Shinto". From the 8th century onwards, Shinto gradually absorbed what was beneficial to itself from Confucianism, until the 17th century, when Shinto and Confucianism were further combined to form "Confucian Shinto" in Japan.
Confucian culture, as a means used by Chinese emperors for thousands of years, is because it greatly strengthened the power of the monarch, and the Japanese rulers took this point even more seriously, so they did not hesitate to spend hundreds of years learning to absorb Confucian culture, and then labeled themselves as "the kingdom of god".
During that period, the rulers of the Meiji Restoration vigorously propagated the idea of the Kingdom of God and compiled it into textbooks to indoctrinate the people. He preached that japan was born of the gods and blessed by the gods. The Japanese who live in it, that is, the "Heavenly Son of Heaven and Heavenly Son", are the most outstanding gods in the world and should rule the world, and thus it has become the theoretical basis for watching militarism launch foreign aggression.
Some people will use the "Yellow Descendants" to fight back against me, but if you look closely, when will Chinese call themselves the best nation? "56 ethnic groups and 56 flowers", the Han nationality is very inclusive; in contrast, Japan is like "Xi Shi Gong", only learning the surface.
Emperor Hirohito
Emperor "Living Man God"
Of course, the land created by God must be ruled by the sons of God. Thus, the two creator gods "gave birth to the beginning of the land, and gave birth to the gods." "The most famous of the gods is the Amaterasu god who rules the kingdom of heaven, the moon reading god who rules the sea, and the male god suze who rules the world.
Amaterasu is the beautiful sun goddess and the supreme commander of the gods. She ordered her grandson Qiong Qiong to rule the place of Izumo and gave him three artifacts: the Eight-Foot Goku Jade, the Divine Mirror, and the Grass Cone Sword. These three artifacts became the most precious treasures of the Japanese Imperial Family and a symbol of the imperial throne.
shogunate
After the death of Qiong Qiong, his great-grandson Yan Huo took over his rule and led an army from Kyushu to the Yamato Kingdom of Honshu, where he succeeded to the throne. Yanhuo Izumi is the legendary first emperor of Japan, Emperor Shenmu.
Emperor Shenmu was enshrined by later rulers as the founding king of Japan, saying that he ruled Japan by the will of god more than 2,600 years ago, from a god to a man. Subsequent emperors, all of whom were his descendants, all had the bloodline of the great god Amaterasu, and were "living gods" with supreme authority.
In this way, the rulers of Japan fabricated the myth of "divine right of kings".
Tokugawa shogunate
However, the emperor did not actually hold power in Japan for a long time. At the peak of the Meiji Restoration, after the Meiji Restoration, the emperor became more of a puppet of the "regent" and "shogunate", and his lineage was also questioned by historians. The famous Japanese historian Nan Liangjin believes that not only is it not worth mentioning that Shenwu is changed by a god, but even whether there is a Shenwu or not.
It was not until the end of the Tokugawa shogunate that the Fallen Curtain Faction launched a large-scale curtain-down campaign under the banners of "Honoring the King's Shogi" and "Imperial Government Retro", and finally won the victory. It was only in modern Japan that theocratic imperial system was established. However, after becoming strong, Japan played with fire and self-immolation, launched a crazy war of aggression, and at the end of World War II, it was completely defeated.
After the defeat, the departure of the Japanese emperor became the focus of public attention, as the leader of the theocratic unity, the emperor undoubtedly has an unshirkable responsibility, international public opinion strongly demanded the abolition of the emperor system, and even 30 percent of the public opinion in the United States demanded that Emperor Hirohito be hanged. But the United States wanted to use the emperor's great prestige to rule Japan, eventually leaving behind the "emperor system", but the defeated Japanese emperor after the war had only symbolic power. The divinity of the emperor was also negated by Emperor Hirohito in his Declaration on Earth.
