Chōon Falls Park (Chōon-no-Taki Kōen) is a summer nature stop in the mountains of Ukiha, about an hour and a half east of central Fukuoka by car. Visitors come for the 27-metre waterfall, a cold-water flowing pool and seasonal nagashi-sōmen noodles.

What to see at Chōon Falls Park
Chōon Falls

Chōon Falls is about 27 metres high. Together with Uogaeri Falls and Onobuchi Falls, it forms the Kose Three Falls area. Shaded paths and the sound of water make it a pleasant break from summer heat, but wet rocks and paths can be slippery. Wear shoes with secure soles.
The cold-water flowing pool

The seasonal pool uses cold river water and includes a slide. It often feels much colder than a normal outdoor pool. For a future season, bring dry clothes, a large towel and a light outer layer, and give children frequent breaks. The 2027 schedule has not yet been announced.
Seasonal nagashi-sōmen

Nagashi-sōmen is a Japanese summer experience in which chilled thin noodles are served in flowing water. The 2026 service costs ¥600 per serving, does not accept reservations and finishes when the day’s noodles sell out. It closes in rain. Outside food cannot be eaten in the sōmen venue; follow staff instructions for drinks and personal necessities.

Access and parking
A car is the most practical way to reach the park. Allow roughly 25 minutes from Haki IC on the Ōita Expressway, then continue on local mountain roads. International travellers using a rental car should plan the return drive before entering the hills and avoid a tight schedule after dark.
- Standard cars: 107 spaces
- Large vehicles: 2 spaces
- Accessible parking: 1 space
Summer weekends can be busy, and rain or lightning may change operations at short notice.

Turn the visit into a Ukiha day trip
Because the park is outside central Ukiha, it works best as part of a driving route. Stop at Michi-no-Eki Ukiha for seasonal fruit and local products, or walk through the white-walled historic streets of Chikugo-Yoshii.
After cold-water play in a future pool season, change into dry clothes before driving. Chikugogawa Onsen and Harazuru Onsen both offer options for a warming bath on the return route. Compare other nature spots in the Fukuoka river-play guide.
