Raiden, the father of Raitaro, is the god of thunder (rai) and lightning (den) in the Shinto and Japanese folklore...
He is fond of eating human navels.
Some Japanese parents tell their children to hide their belly buttons (or navels) during thunderstorms, so that they are not taken away...
It is said that the only protection against him is to hide under a mosquito net.
Raiden is also known by the following names:
>> Yakusa no ikazuchi no kami: Yakusa (八, eight) and ikazuchi (雷, thunder) and kami (神, spirit or deity)
>> Kaminari-sama: kaminari (雷, kaminari, thunder) and -sama (様, a Japanese honorific meaning "master")
>> Raiden-sama: rai (雷, thunder), den (電, lightning), and -sama (様, master)
>> Narukami: naru (鳴, thundering/rolling) and kami (神, spirit or deity)
Raiden is portrayed as a muscled sharp-clawed demon with red skin, sitting on a cloud, shooting arrows at the enemies of the people.
Raijin's companion is the demon Raiju. In Japanese art, the deity is known to challenge Fūjin, the wind god.
