佐久島

The ferry from Isshiki takes about twenty-five minutes, and by the time the engine slows, the black coal-tar walls of the western settlement come into view, packed in a fan across the slope. Sakushima sits near the middle of Mikawa Bay, two settlements connected by narrow lanes, the hills behind them low enough that you can cross the island on foot. There are no rivers here. The coastline simply turns and turns again.

In the older quarter near the west port, houses lean toward each other along paths too narrow for cars, and the dark-walled townscape — sometimes called the black pearl of Mikawa Bay — carries the weight of the island's earlier life as a shipping waypoint. Hachiken Shrine stands quietly above its old precinct; Amidaji and Sūunji keep their calendars of Yōkakō and the August bon dance, the latter held on the fifteenth, a practice continued across generations. Contemporary artworks appear at the edges of fields and along the harbor walls, less an exhibition than a layer added to what was already there.

Walking the Yabutsubaki trail, the camellias close overhead like a tunnel, and the burial mounds of the Sakushima kofun group surface in the brush without much signage. Konowata and hamadaikon turn up on local tables; the ferry timetable is short; winter brings strong winds rather than snow. Such places, perhaps, ask less of a visitor than they offer — a slower clock, a smaller geography, and the steady company of the sea on every side.
