Represented as a red demon surrounded by a circle of drums (the "thunder"), his image is quite scary, but the Japanese tradition is often surprising: Raijin is also considered a good kami, a god of agriculture, and even its lightning has a good side: it fertilizes the rice plants. That's why, in the Japanese tradition, a place hit by lightning was marked with bamboo and shimenawa, being considered beneficial for the rice crops.
Recently, Raijin's popularity reached even the pop culture, not only in Japan but also in the West, where he is better known with his other name, Raiden (from rai "thunder" and den "lightning").
The most famous and easily accessible place where you will see a beautiful Raijin statue is the Kaminarimon Gate from Asakusa, Tokyo. But from what I visited until now, the most impressive statue of Raijin is the one from the Nitenmon Gate at the Taiyuin Mausoleum, Nikko, photographed here...
