Komagata Jinja is the ichinomiya — the leading shrine — of the former Rikuchu Province, in present-day Iwate. It has a car park (about 30 spaces), free. Opening hours end at 16:30 (prayer rites). Without a car, the shrine's own website gives 1 route from a station (on foot), one of them a walk of 10 min; the station names are listed below. Its principal annual festival (reisai) falls on September 19 every year. The nearest other ichinomiya is Shiwahiko Shiogama Jinja, 92 km to the south in a straight line.
