Tsukuyomi (月読) or Tsukuyomi-no-Mikoto (月夜見の尊), also known as Tsukiyomi or Tsuki no Miya, is the god of the moon and night in Japanese Shintoism and mythology. He lived in the heavens, called Takama-ga-hara, with his sister, the goddess of the Sun, Amaterasu.
The name Tsukuyomi is a combination between the kanji for moon (tsuki) and reading (yomu). Another interpretation says that the name comes from the combination between "moonlit night" (tsukiyo) and the verb to look (miru). This deity has several names:
Tsukuyomi-no-Mikoto (月読命, 月弓尊, 月讀尊, 月夜見尊), Tsukutsumi-no-Mikoto (都久豆美命), Tsukuyomi-Otoko (月読壮士, 月人壮士). As this last name indicates, Tsukuyomi is traditionally considered a male kami, but some interpretations, probably influenced by the Chinese metaphysics of yin and yang, consider him a female or androgynous deity.
Tsukuyomi appears very little in Japanese mythology.
He first appears in the myth of Mihashira-no-Kami (三柱の神) also called Mihashira-no-Uzunomiko, the three noble divine children of Izanagi. He is the second of the three children born when Izanagi, the god who created the world, was cleansing himself of his defilements by taking a bath at the mouth of the Tachibana River in Himuka (present-day Miyazaki Prefecture).
It is said that he was born when Izanagi washed his right eye. But it is sometimes said that he was born from a copper mirror that Izanagi held in his right hand. Tsukuyomi then climbed the heavenly ladder to join the heavens, Takama-ga-hara, and his sister, Amaterasu.
However, he made her angry when he killed Uke Mochi, the goddess of food. Amaterasu did not want to see Tsukuyomi anymore and moved to another part of the sky. The legend explains that this is why day and night are never together. In other more recent versions, it is Susanoo, the god of storms, who kills Uke Mochi.
In the Kojiki, it is said that when Tsukuyomi was born from the right eye of Izanagi, the same Izanagi gave him the Night Kingdom.
