A bluish-white bath beneath the folding-screen rock
Kurokawaso sits a little downstream from the village, and its open-air bath faces the towering cliff called Byobu-iwa — a view that keeps day visitors coming. The sodium-chloride-bicarbonate-sulfate water takes on a bluish-white tint in certain light, unlike any other inn here. With a dedicated day-visitor area and three private baths it suits families and couples, and as one of the few open until 21:00 it makes a good final stop on a Nyuto Tegata round.
Tips & cautions
- General bathing starts at 10:30 (no early mornings). Evenings are quiet and the rock is lit up.
- Private baths cannot be booked by phone — check availability at the desk; guests first.
- Nyuto Tegata valid for the regular baths only. Bring a towel.
- Occasional maintenance closures — call 0967-44-0211.
Getting there
About 10 min on foot from the Kurokawa Onsen bus stop (Manganji 6755-1). ~1 h from Hita IC or 1 h 30 min from Kumamoto IC by car. Free parking.

More in this area
Kurokawa Onsen Nyuto Tegata (bath-hopping pass)
One cedar 'nyuto tegata' pass (¥1,500) admits you to any three of the rotenburo at Kurokawa's 26-odd ryokan. Valid for six months, and one of the three stickers can be spent on food or souvenirs instead. Most inns accept bathers roughly 8:30–21:00, but hours vary and some close for cleaning or when full. Buy the pass at any ryokan or the association office 'Kaze no Ya'.
Ana-yu communal bath
A tiny bath hut on the Tanohara River, rebuilt by donations in 2022 after the 2020 floods (now separate men's and women's rooms). Slide the shutters open and it becomes almost open-air. ¥200 in the box.
Jizō-yu (Kurokawa communal bath)
The oldest communal bath in town, next to the Jizō hall that gives Kurokawa its identity. Not covered by the bath-hopping pass, but only ¥200. No soap; the water runs hot.
