大多府島

The breakwater at Otabu Island still holds its original line of stones, low and patient against the Seto Inland Sea. Built under the direction of Tsuda Nagatada in the Genroku era, the Genroku Hato was raised when the Okayama domain opened the harbor as a wind-shelter port along the sankin-kotai route. Three centuries later, the stones have not been rearranged. They simply continue their work, holding the small bay on the island's northern side where boats still come in from Hinase port, six kilometers north across the water.

Walking the island takes very little time, but the texture asks for slowness. A hexagonal stone-framed well, once the only source of drinking water for trading ships, sits where it has always sat. The Toro-do, a wooden square tower rebuilt in the late twentieth century, marks the summit as a night beacon for passing vessels. On the southern side, the cliffs turn rougher: the Meoto-iwa, two rocks leaning together, and the cave called Kanzaburo, with its quiet legend of counterfeit domain notes. Kasuga Shrine, built in the early eighteenth century, keeps its own corner of the woods.

What distinguishes this island from the mainland coast of Bizen is the scale of its silence. There is no through-traffic, no train, no convenience store rhythm. A second residence here would mean accepting the ferry timetable as the day's true clock, and a longer stay would mean learning which mornings the sea allows departure. For a shorter visit from abroad, the island offers something the Inland Sea rarely shows so plainly: a working Edo-period port still doing, in its modest way, what it was built to do.
