Overview
Ōno Shima is a sandbar island in the lowest reaches of the Chikugo River, straddling Ōkawa City in Fukuoka Prefecture and Saga City in Saga Prefecture. Though a single island, it changes its name by prefecture: the northern half in Fukuoka is called Ōno-shima, while the southern half in Saga is called Ōdakuma—an unusual arrangement. The fields and fishing harbors spread across this low-lying delta, where river meets sea, still convey the bounty of the great river flowing into the Ariake Sea and the lives of the people rooted here.

History
Ōno Shima is a sandbar formed at the lowest reaches of the Chikugo River as it empties into the Ariake Sea, and its origin is said to date back to 1601. On land built up from silt carried by the river, people settled and, through repeated reclamation and flood control, created fields and villages. Behind the fact that one island is called Ōno-shima on the Fukuoka side and Ōdakuma on the Saga side lies a history particular to this area of tangled prefectural borders, telling the story of a land that has lived alongside the river.
Access
The island lies at the southwestern edge of Ōkawa City, Fukuoka, at the mouth of the Chikugo River. It is usually reached by car across a bridge from central Ōkawa or the Saga City direction, with flat surroundings of fields and fishing harbors. Public transport is limited, so a rental or private car is realistic. Confirm exact routes and the status of bridges or ferries via official information before you go.
Best season
Early summer, when the fields turn green, and the harvest season of autumn are fine times to enjoy the peaceful scenery unique to a river-mouth sandbar. Close to the Ariake Sea, the views of the river surface and tidal flats change with the seasons. To enjoy the bustle of the harbor and seasonal produce, check local or official information for timing before visiting.

Did you know?
💡 That the north and south of a single island belong to different prefectures, changing even its name between Ōno-shima and Ōdakuma, is unusual across Japan. That people's lives have accumulated here since 1601, at the very mouth of the Chikugo River where water and land contend, is itself the essence of a walk around this island.
