Iyahiko Jinja stands at the edge of Nakajima Park in Sapporo. Settlers from Niigata founded it in 1912 with a spirit divided from Yahiko Jinja in their home province, enshrining Ame-no-Kaguyama, and in 1970 it received Sugawara no Michizane from Dazaifu Tenmangu. The grand festival falls on 27 July.
