I want to know Japan’s three major artifacts! Please elaborate! The origins of the three great artifacts!

Japan’s three major artifacts are: Kusanagi Sword, Yata Mirror and Yasaka Qiongqudama. Grass pheasant sword: The grass pheasant sword is hidden in the body of a big snake with eight heads and eight tails (some say it only has eight heads). The Kusanagi sword that is still preserved in Japan is respected as a national treasure by the Japanese. It not only has cultural relic value in Japan, but is also worshiped as a sacred object or sacred object. It was first called "Tian Cong Yun". The "Nihon Shoki" also records the story of the Kusanagi sword's appearance. Among the three treasures used as tokens (equivalent to jade seals) by Japanese emperors when they came to the throne, there is also the Amancongyun Sword - of course, as Rune Benedict, the author of "The Chrysanthemum and the Sword" said, the original sword has been in a turmoil It sank to the bottom of the sea, and now the royal family only uses imitations. Yata Mirror: Yata means big or beautiful. The Yata Mirror originated from the Chinese water mirror, also known as "Jian". Just put water in a metal basin and use it to shine on your face. Later, it gradually developed into a bronze mirror, with auspicious patterns such as pine, bamboo, plum, turtle and crane painted and engraved on the back. During the Yayoi period, mirrors were introduced to Japan from China. At that time, the Japanese regarded mirrors as sacred objects and hung them on their chests as tools to ward off evil spirits. After that, the types of mirrors increased. Among them, the Yata Mirror, as the royal spirit of Amaterasu, is enshrined in Ise Jingu Shrine, the ancestor of Japanese shrines. Mirrors play an important role in Japanese folklore. The Japanese believe that the fact that a mirror reflects things and people reflects its mystery and magic, so there are many beliefs and legends about mirrors. It is said that it can bring good luck, reflect the human heart, reveal the nature of the devil, and predict good and bad luck in life and death. As a result, some people in Japan still believe that a broken mirror is a bad omen. You cannot cross the mirror and cover the mirror on non-auspicious occasions.

The origin of "Yata Mirror": Same as above Yasaka Qiongquyu: Source:

The earliest ancestors of the Japanese are Izanagi Ming (male) and Izanami Ming (male) Female) Two gods, these two are like Adam and Eve in the Bible who created the Japanese archipelago, and also cooperated to give birth to the sons of God who are in charge of all walks of life (is this simply the Eastern version of the Bible)? Among them is Amaterasu, the god of the sun who was born from Izanagi's left eye (it is unclear whether this person is a boy or a girl). This neither male nor female god is still the ultimate leader of Japanese Shinto and enjoys similar Zeus-level treatment in Greece. Susanoo (Poseidon), who was also born from the nose of Heavenly Father Izanagi, was expelled from the divine world by his sister (or brother?) Amaterasu because he was too lawless. As a result, he accidentally completed the beheading in the mortal world. The great achievement of killing Yamata no Orochi. (The so-called Yamata no Orochi is a giant monster with eight snake heads in Japanese legend). The three descendants of Suzuo are responsible for taking care of three artifacts. These three artifacts are the Kusanagi sword, the eight-foot magatama and the Yata mirror. Their surnames also changed to Kusanagi along with these three artifacts. Bachi Qiong and Bata. The three major families are also responsible for monitoring the sealed Yamato no Orochi. However, out of jealousy towards Kusanagi, Yachiqiong betrayed his ancestors and took refuge with Yachi no Orochi and changed his surname to Yagami.
