Overview
The Atoda River is a Class A river flowing through Nakatsu City in Oita Prefecture, part of the Yamakuni River system. Also known locally as the Koto River, it is the second-largest tributary of the Yamakuni after the Yamautsuri River. It is a gentle countryside stream that changes character between its upper and lower reaches, threading through the quiet rural landscape of inland Nakatsu rather than any flashy sightseeing spot.

History
As part of the Yamakuni River system, the Atoda has long nourished the mountain hamlets of Nakatsu. Above its confluence with the Nishitani River, the stream is called the Higashitani River, formed where several valley brooks gather into one course. The elegant alternate name Koto River hints at a long-standing bond between the local people and their water. For details on flood control and place-name origins, check official Nakatsu City information.
Access
The river runs through Nakatsu City in Oita Prefecture, near 33.49 N and 131.17 E. Aim for the inland area reached by following the Yamakuni River upstream from central Nakatsu. Public transport is limited, so a rental car is the practical way to visit. Confirm exact routes and parking with Nakatsu City or local official sources before you go.
Best season
The fresh green of early summer and the clear water and mountain colors of autumn are the most pleasant times to visit. After the rainy season or heavy rain the river can swell, so watch the weather and the state of the water when approaching the banks.
