From the Tsuma town center, local signage points toward the dam; the drive from the town center takes roughly 10 minutes on a well‑maintained rural road.
- Parking: A small free parking lot sits near the dam’s visitor area. Space is limited, so arriving early—especially on weekends or holidays—is advisable.
By Public Transport
If you prefer trains and buses:
- Train: Take the JR Kyushu Nippō Line from Miyazaki Station to Tsuma Station (approximately 30 minutes).
- Bus/Taxi: From Tsuma Station, a local bus runs a few times a day toward the dam, or you can hire a short‑distance taxi (≈ 5 km).
Because the bus schedule is infrequent, checking the latest timetable on the Miyazaki City Bus website before you travel is essential.
Walking & Cycling
For the adventurous, the route from Tsuma town center to the dam is a pleasant 2‑kilometer walk or bike ride through gentle countryside. The path is relatively flat and offers occasional viewpoints of rice paddies and forested slopes.

- Respect Local Rules – Swimming is not officially permitted in the reservoir, but the nearby waterfall does allow a quick splash. Keep the environment clean; dispose of trash in designated bins.
