Owari Province Claimant (ronsha)
Omiwa Jinja (Owari)
大神神社
Omiwa Jinja (Owari) is one of the shrines claimed as the ichinomiya — the leading shrine — of the former Owari Province, in present-day Aichi. It has a car park; the sources we checked give neither its size nor a fee. Opening hours end at 15:00 (shrine office). Without a car, a local tourism body gives 1 route from a station (on foot), one of them a walk of 5 min; the station names are listed below. Its principal annual festival (reisai) falls on October 10 every year. The nearest other ichinomiya is Masumida Jinja, 1.9 km to the north-east in a straight line.

Straight-line distances between the shrines, not road distances. Across mountains or water, the drive is much longer.
Why this shrine is called an ichinomiya
Claimed by the shrine
The shrine itself uses the title, but does not name the historical document it rests on.
Listed on the map published by the Ichinomiya Pilgrimage Association.
The shrine’s authorised website says it “was designated the ‘ichinomiya of Owari’ in the Nara period, and is recorded in the register of deities of the Engishiki as a shrine listed in that code.” This does not fit the period of the system the city of Ichinomiya describes, which it traces to the order in which provincial governors made their visits in the Heian period.
