佐柳島

The ferry from Tadotsu port runs northwest across the Seto Inland Sea, calling at Takamijima before reaching the narrow island of Sanagishima. Cats move along the stone walls of the alleys, settling into shadows between houses. Two villages anchor the island: Honura at the southern harbor, Nagasaki at the northern one, each with its own port and its own rhythm of arrivals.

What remains here, beyond the cats that have given the island its informal name, is the practice of ryōbosei — the dual grave system — still visible at the burial ground in Nagasaki, designated a prefectural folk cultural property. At Jōrenji temple lies the grave of Hirata Tomizō, a crew member of the Kanrin Maru who died on the island. The hills rise to Kōtōzan above the sea, and the working life of the place — sashiami net fishing, octopus pots, small field crops — turns mostly inward, toward self-consumption rather than export.

Compared with the busier islands of the Shiwaku archipelago, Sanagishima keeps its distances long and its sounds few. The Saturday boat from Kasaoka, routed through Manabeshima, is the only alternative way in. One comes to understand that the island's quiet is not emptiness but a particular density: stone walls, salt air, a cat asleep on a wall, a grave older than memory.
