Raijin (雷神), also known as Raiden-sama, Yakusa no ikazuchi no kami, Kaminari-sama, and Narukami, is a god of lightning, thunder and storms in the Shinto religion and in Japanese mythology. The name "Raijin" is derived from the Japanese words kaminari (雷, "thunder") and kami (神, "god"). He is typically depicted as a demon-looking spirit beating drums to create thunder, usually with the symbol tomoe drawn on the drums.
Raijin was created by the divine pair Izanami and Izanagi after the creation of Japan. There is a legend which says the eight lightning gods were charged with protection of the Dharma by the Buddha. This kind of syncretism, called Shinbutsu-shūgō, is not unusual in Japan, even after the 1868 order that formally separated Shinto and Buddhism. Raijin's companion is the demon Raiju. In Japanese art, the deity is known to challenge Fūjin, the wind god.
Some Japanese parents tell their children to hide their belly buttons during thunderstorms. This is due to a folk belief that Raijin is sometimes credited with eating the navels or abdomens of children, and in the event of thunder, parents traditionally tell their children to hide their navels so that they are not taken away.
