Yasuura Shrine seems like it was a fairly major shrine in the past. Founded in 938 on the waterfront, aound the end of the 12tch Century it was moved a little inland to its current location in a wide, wooded hill.
The three kami enshrined here are Ikutsuhikone no mikoto, Amatsuhikone no mikoto, & Kumanokusubi no mikoto, 3 of the 5 males born when Susano chewed up and spat out Amaterasu's jewels.
There is a line of 13 secondary shrines that were moved here in 1912 when the government closed down half the shrines in the country.
There was some evidence of recent ritual activity for the new year, but being somewhat removed from the center of Yukuhashi it lacked the lanterns and banners at other shrines I had visited that morning.
