Oura functions as Yamada Beach's forgotten appendix—technically continuous with the town's main strand, but separated by a kilometer of seawall and a psychological boundary where maintained facilities give way to reconstruction staging areas. The sand here is finer than Akahama's, almost grey in dry patches, and the beach slopes gradually toward a bay that can retreat a hundred meters at low tide.

Tetrapod barriers line the upper beach in staggered rows, concrete pyramids softened by barnacles and sea lettuce. They're tsunami mitigation, installed after 2011, and they create a distinctive rhythm along the backshore—human geometry against the organic curve of the coastline. Between the barriers and the waterline, you have unobstructed sand, marked only by the tracks of shorebirds and the occasional beachcomber.
The bay's shallow depth keeps the water relatively warm by Sanriku standards, and the color shifts from milky jade near shore to deeper teal toward the mouth. On calm days, the surface reflects the fishing boats working the outer channels, their hulls appearing as inverted silhouettes. The only sounds are the mechanical clatter of equipment from Yamada's working harbor a kilometer south and the steady, unhurried wash of low waves. This is a beach defined by adjacency—near enough to town for convenience, far enough for effective solitude.
