Ikisu Jinja

History

According to shrine tradition, Ikisu Jinja’s origins trace back to the reign of Emperor Ojin, when it was first established at a site called Hikawa, somewhat west of its present location (now Hikawa, Kamisu). In 807, early in the Heian period, Fujiwara no Uchimaro, acting on the orders of Emperor Heizei, relocated the shrine to its current site in Ikisu, close to the Tone River. This date of relocation, April 13, is still observed today as the date of the shrine’s most important festival, the Reitaisai.

The principal deity is Kunado no Kami (also written with characters meaning “diverging paths”), long worshipped as a guardian of crossroads and boundaries, a protector against misfortune and of safe travel, and a god of wells. Enshrined alongside as secondary deities are Ame no Torifune no Kami, who in Japanese mythology’s kuniyuzuri story guided Takemikazuchi and Futsunushi, and the Three Sumiyoshi Deities (Sokotsutsu no O, Nakatsutsu no O, and Uwatsutsu no O), gods of maritime safety fitting for a shrine that once stood at a key point on the Tone River’s water transport routes.

Ikisu Jinja is counted, together with Kashima Jingu (Kashima, Ibaraki) and Katori Jingu (Katori, Chiba), among the “Togoku Sansha,” the Three Shrines of the Eastern Provinces. In the Nihon Shoki’s account of the kuniyuzuri myth, Kashima’s Takemikazuchi and Katori’s Futsunushi were sent down to pacify the land of Ashihara no Nakatsukuni, guided by Ikisu’s Kunado no Kami — a shared origin that binds the three shrines together in mythology as well as geography. When water transport on the Tone River flourished during the Edo period, it became popular among ordinary pilgrims returning from Ise Jingu to complete their journey with a purification visit to all three shrines, known as the “Shimo-sangu Meguri” or Togoku Sansha pilgrimage — a custom that continues to draw visitors as the “Togoku Sansha Meguri” today.

Highlights

The feature that best symbolizes Ikisu Jinja is the great torii standing on the bank of the Tone River, flanked by the twin wells known as Oshioi. Each square well contains a small torii of its own; the eastern well is called the “male jar” and the western the “female jar.” Together with Ise Jingu’s Akebono-i and the Naoi well of old Yamashiro Province, Oshioi is counted among Japan’s “Three Sacred Springs” — a remarkable freshwater source that is said to have kept flowing clear for over a thousand years despite sitting in this brackish, tidal stretch of river. Tradition holds that a woman who drinks from the male jar and a man who drinks from the female jar will be bound together, and Oshioi is accordingly also known as a spot for blessings in relationships.

Beyond the approach and through the shrine gate lies a quiet compound centered on the haiden (worship hall) and honden (main hall). The honden was rebuilt in 1723, destroyed by fire in 1960, and reconstructed in 1963. The grounds also include a chikaraishi (traditional strength-testing stone) and several subsidiary shrines, including an Inari shrine associated with business prosperity and bountiful harvests, all reflecting Ikisu Jinja’s standing as one of the Togoku Sansha.

Visiting Tips

The grounds can be visited at any hour, but the shrine office, which handles goshuin and amulets, is open 8:30–16:00, with goshuin issued 9:00–16:00 and prayer requests (gokito) accepted 9:00–15:30. Free parking for 82 standard vehicles is available on the grounds, with room for large tour buses as well. Many visitors combine a trip here with Kashima Jingu and Katori Jingu as part of a full “Togoku Sansha” circuit in a single day; each leg of the drive between the three shrines takes roughly 30–40 minutes.

Annual Festivals

• Reitaisai Grand Festival (April 13 each year): Held on the anniversary of the shrine’s relocation to Ikisu in 807, this is Ikisu Jinja’s most important festival. The chief priest of Kashima Jingu serves as officiant and recites the ritual prayers, a tradition reflecting the deep ties between the two shrines.
• Kinensai (Prayer Festival, spring): Held as the agricultural season begins, praying for a bountiful harvest of the five grains.
• Mikoshi Procession: A portable-shrine procession through the parish neighborhoods that draws a lively crowd from the local community.

Nearby Food & Sightseeing

• Kashima Jingu: A fellow member of the Togoku Sansha, about a 30–40 minute drive from Ikisu Jinja; many visitors combine a visit to both.
• Katori Jingu: Also one of the Togoku Sansha, about a 30-minute drive from Ikisu Jinja.
• Suigo-Tsukuba Quasi-National Park irises: The wetlands along the Tone River bloom with irises in early summer, and boat tours of the waterways are also available.
