Complete Guide to Raiden Shrines: A Thorough Explanation from the Head Shrine to Major Shrines Nationwide
Raiden Shrines (Raiden Jinja) are a general term for shrines that include “Raiden” in their name, and are numerous, mainly distributed in the Kanto region. They are widely worshipped as gods of protection against lightning and have also been revered as gods that bring blessings to agriculture and water. This article will provide a detailed explanation of the history, enshrined deities, blessings, and cultural properties of major Raiden Shrines throughout Japan, focusing on the head shrine, Raiden Shrine in Itakura-machi, Gunma Prefecture.
What are Raiden Shrines?
Raiden Shrines are a general term for shrines that include “Raiden” in their name, and are numerous in the Kanto region, particularly in Gunma, Saitama, Tochigi, and Ibaraki prefectures. While they are uniformly worshipped as gods of protection against lightning, the enshrined deities and history are not necessarily consistent across individual shrines.
Similar shrines include Raijinja (Thunder Shrine) and Denjinja (Electric Shrine), which are also worshipped in various locations as shrines based on the worship of the thunder god.
Historical Background of Raiden Worship
The worship of the thunder god has existed in Japan since ancient times. Thunder has been feared as a symbol of the wrath and power of the heavenly gods. At the same time, thunderstorms brought beneficial rain to crops, so they were also objects of prayer for bountiful harvests. Lightning strikes were particularly frequent in the Kanto Plain, and it is believed that the worship of Raiden Shrines spread as a way to protect oneself from lightning damage.
Raiden Shrine Headquarters (Itakura Town, Gunma Prefecture)
Located in Itakura Town, Ora District, Gunma Prefecture, Raiden Shrine is known as the head headquarters of Raiden Shrines scattered throughout the Kanto region, especially in the middle and upper reaches of the Tone River. It is also called “Itakura Raiden Shrine” to distinguish it from other Raiden Shrines.
Founding and History
The founding of Raiden Shrine is attributed to Prince Shotoku, and it is said to have begun in 598 AD (the 6th year of Emperor Suiko’s reign) when a shrine was built on a floating island on the shore of Inara Marsh. Later, during the reign of Emperor Tenmu, it is believed to have been moved to its current location. In 1674 (Enpō 2), a major renovation of the shrine buildings was carried out by order of Tokugawa Tsunayoshi (later the 5th Shogun of the Edo Shogunate), who was the lord of the Tatebayashi Domain in Kōzuke Province. As a result of this achievement, Raiden Shrine received the patronage of the Tokugawa family and was granted the honor of being permitted to use the Tokugawa family crest, the three-leaf hollyhock.
Deities and Blessings
The main deities enshrined at Raiden Shrine are the following three:
- Ōikazuchi no Ōkami: God of thunder, offering protection from lightning
- Honoiikazuchi no Ōkami: God who governs fire and thunder
- Wakeikazuchi no Ōkami: God who divides thunder, god of protection from lightning
Due to these deities, Raiden Shrine is believed to offer the following blessings:
- Protection from lightning and lightning strikes
- Prayers for rain and bountiful harvests
- Blessings of water
- Protection from evil and misfortune
- Family safety
- Good health
- Protection from negative influences
