Raijin, also known as Kaminari-sama, Raiden-sama, Narukami Raikou, and Kamowakeikazuchi-no-kami is a god of lightning, thunder, and storms in Japanese mythology and the Shinto religion. He is typically depicted with fierce and aggressive facial expressions, standing atop a cloud, beating on den-den daiko drums with tomoe symbols drawn on them. Iconography of Raijin are often found in Japanese temples and shrines. He is usually depicted alongside Fūjin, the god of wind.
The name "Raijin" is derived from the Japanese words 雷 and 神.
Raijin is often depicted with a fierce, frightening face and a muscular figure with gravity-defying hair. He is surrounded by Taiko drums that he plays to create the sound of thunder. Raijin holds large hammers in his hands that he uses to play the drums. In some cases, Raijin is portrayed with three fingers which are said to represent the past, present and future. Two of the most notable sculptures of Raijin are located in the Sanjusangendo temple and the Taiyuin Rinnoji temple.
Raijin and Fujin reside side by side in the Kaminarimon gate that guards the entrance to the Sanjusangendo temple. These sculptures are made of wood with lacquer, gold leaf and paint along with crystal, inlaid eyes. The Raijin and Fujin sculptures in Sanjusangendo are considered national treasures.
In the Taiyuin Rinnoji temple, Raijin and Fujin are located in the Niten-mon gate. They are made of wood with paint and are seen with their token talismans, Raijin's drums and Fujin's wind bag.
Raijin is also often seen in the company of his brother, Fujin, and his son, Raitaro. He is often seen fighting with Fujin, mending his drums, or causing mischief. He is also shown in the company of Raiju, a thunder-beast or thunder demon which also acts as his totem animal and usually a dog or wolf.
In the myths recorded in the Kojiki, after Izanami died from the wounds inflicted on her by the birthing of Hinokagutsutchi, her husband Izanagi followed her down into Yomi no Kuni, the land of darkness.
