Museum Reception

Last night, the campus museum hosted a reception to celebrate the opening of its new exhibits. I think I was the only freshman who went, but there were a lot of faculty and older students in attendance. I bring it up because as I was walking through the exhibits, I noticed this Japanese tsuba, a decorative hand guard for a samurai's katana.

It caught my attention, because its eyes, which were covered with a brighter metal (gold leaf, maybe?), shone in its display. Upon taking a closer look at it, I immediately recognized Raijin, and felt a rush of validation when I looked at the information card and saw that it was, indeed, Raijin being depicted.

Raijin is the Japanese thunder god ("rai" being thunder and "jin" an alteration of "shin", which in turn is the same "shin" in "Shinto", and means "god"). He is often shown with (or competing against) Fuujin, the wind god. According to Shinto mythology, after Izanami and Izanagi created Japan, the Buddha entrusted eight Raijin to protect the Dharma (assigned a variety of meanings, but primarily referring to natural law). This sort of syncretism between Shintoism and Buddhism was and is very common among the Japanese. When there is a storm, Raijin beats his drums (note the drumsticks he holds in the tsuba) and produces thunder. His drums are usually topped with a mitsudomoe symbol, a variant of the tomoe and a trinity figure thought to represent Man, Earth, and Sky. The mitsudomoe is also visible in the tsuba as the circles above and below the central slit for the blade - the top retains its bright metallic covering, making the three-pronged symbol easy to see. Those who are familiar with Japanese mythology might look at Raijin's iconography and assume him to be a demon, or oni. Some versions of the myth do indeed suggest that Raijin is a reformed oni, thus explaining the resemblance. One legend says that Raijin likes to eat children's bellybuttons, and so some parents may warn their children to keep their navels covered during thunderstorms. Another story, found in Judika Illes' Encyclopedia of Spirits, states that Raijin saved Japan from the 1274 Mongolian invasion by firing thunderbolts at the Mongol ships.

Raijin is never found without his loyal companion (and perhaps pet), Raijuu, the thunder beast. This spirit, often taking the form of a white or blue wolf or fox, is the source of electricity and lightning, and has the dubious honor of being the inspiration for the Pokémon, Raichu. Another explanation of the bellybutton story is that Raijuu likes to fall asleep in people's navels, and Raijin must strike him with lightning to wake him up, thus harming the sleeper. Those who believe this version of the story may sleep on their stomachs in bad weather, whereas others say that Raijuu only sleeps in the bellybuttons of people sleeping outside.
Modern practitioners wishing to honor Raijin could call upon him for protection during storms or a power outage. While I imagine there are specific rites one may do to honor the thunder god, a small monetary offering is standard fare among the Japanese kami. Unless you live in Japan, it is unlikely that you live near any sort of shrine to Raijin. If this is the case, money could be donated via the internet to help provide relief for storm victims or to help maintain Japanese shrines which honor the thunder god and associated deities.
