The ichinomiya of Shima Province

What the Japanese sources say

Izawanomiya (伊雑宮) and Izawa Jinja (伊射波神社) are both called the ichinomiya of Shima Province, but Izawanomiya does not call itself an ichinomiya. On the official website of the Jingu (Ise Jingu) it is placed as a betsugu (an auxiliary shrine) of the Kotai Jingu, and as a tonomiya (遙宮, written with characters meaning ‘distant shrine’).

For Izawa Jinja, Ise-Shima Kanko Navi, run by the Ise-Shima Tourism and Convention Organization, calls it the ichinomiya of Shima Province.

— The placing of Izawanomiya as an ichinomiya appears to come from the pilgrimage side rather than from the Jingu (this site’s view). The basis for it, however, could not be confirmed.
