Deities and History
Main Deity: Ikonahime-no-Mikoto
The main deity of Ikonahime-no-Mikoto Shrine is, as the name suggests, Ikonahime-no-Mikoto. This goddess is revered as the goddess of love, wisdom, and beauty, and is believed to grant blessings for matchmaking and good relationships.
According to legend, Ikonahime-no-Mikoto was the beloved consort of Mishima Daimyojin (Mishima-no-Kami), the pioneering deity of the Izu Islands, and is said to have nurtured her love with Mishima Daimyojin, who came from the southern seas, in this Shirahama area. This mythical story makes Ikonahime-no-Mikoto Shrine a popular power spot for matchmaking.
Enshrined Deities
Besides the main deity, Ikonahime-no-Mikoto, the following deities are enshrined at Ikonahime-no-Mikoto Shrine:
- Mishima Daimyojin (Mishima-no-Kami): God of courage, prosperity, and development. This is the same deity enshrined at Mishima Taisha (Mishima City, Shizuoka Prefecture), the Ichinomiya (first-ranked shrine) of Izu Province.
- Mime-no-Kami
- Wakamiya-no-Kami
- Tsurugi-no-Mikoto-no-Kami
Because these deities are enshrined together, the shrine was formerly known as “Gosha Myojin” (Five Shrine Deities).
The Story of Mishima-no-Kami and Ikonahime-no-Mikoto
Understanding the history of Ikonahime-no-Mikoto Shrine requires understanding the legend of Mishima Daimyojin and Ikonahime-no-Mikoto.
According to tradition, Mishima-no-kami was originally a deity enshrined on Miyakejima Island in the Izu Islands, and is considered the god who pioneered the Izu Islands. It is said that Mishima-no-kami, along with his beloved consort Ikonahime-no-mikoto, moved from Miyakejima Island to Shirahama (this area), and finally to Mishima Taisha (Mishima City, Shizuoka Prefecture), the Ichinomiya (first-ranked shrine) of Izu Province.
This legend of relocation demonstrates the deep historical connection between the Izu Islands and the Izu Peninsula, and tells of the fusion of ancient maritime and volcanic worship.
Records of the Heian Period and Natural Disasters
The *Nihon Kōki* (Later Chronicles of Japan) contains interesting records concerning Ikonahime-no-mikoto. In the early Heian period, in the 9th year of the Jōwa era (832 AD), it is believed that the wrathful Ikonahime-no-Mikoto caused natural disasters. To appease the goddess’s anger, the imperial court designated Ikonahime-no-Mikoto, along with Mishima-no-Kami, as a “Myōjin” (a shrine of exceptional status worshipped by the state) to be enshrined at a special shrine.
This natural disaster is interpreted as the volcanic eruption on Miyakejima Island in 832 AD. This record offers a glimpse into the ancient worldview that linked volcanic activity in the Izu Islands with the wrath of a god. As a result of this event, Ikonahime-no-Mikoto Shrine became a Myōjin Taisha (a major shrine) receiving special reverence from the imperial court.
History of Ikonahime-no-Mikoto Shrine
The Oldest Shrine in Izu with a 2400-Year History
Ikonahime-no-Mikoto Shrine boasts a history of over 2400 years since its founding, and is considered the “oldest shrine in Izu Province.” Throughout this long history, the shrine has played a crucial role as the center of faith in the Izu region. The rituals at Hitatsuyama have continued since ancient times, and its value as an ancient ritual site is recognized archaeologically. This place, which functioned as a site for worshipping the Izu Islands from afar, is thought to have been deeply connected to the beliefs of seafaring peoples.
Status as a Myojin Taisha (Great Shrine) in the Engishiki Jinmyocho (Register of Shrines in the Engi Era), completed in 927 AD, lists Ikonahime-no-Mikoto Shrine as “Ikonahime-no-Mikoto Shrine, Kamo District, Izu Province, Myojin Taisha.” Myojin Taisha are shrines that received special rituals from the state due to their particularly powerful spiritual efficacy, and there are only a limited number of them throughout the country.
This high status indicates that Ikonahime-no-Mikoto Shrine was considered important at the national level from ancient times.
