Kumamoto Bath Run: Four Hot-Spring Roadside Stations from Yamaga to the Kuma Coast
A 2-day north-to-south crossing of Kumamoto in which every stop has a hot-spring bath: Yamaga's riverside complex, Misato's Samata no Yu, the Itsuki valley above the Kuma River, and Oono Onsen near the Ashikita coast — two of the four with rooms on site.
Kumamoto has more hot water than it knows what to do with, and an unusual number of its roadside stations were built around a bath rather than a shop. String four of them together and the drive becomes a bath run: 150km from the rice plain north of Kumamoto city down to the Shiranui Sea, with a soak every two or three hours and a bed waiting at two of the four stops.
The first, Suihen Plaza Kamoto, sits on the Kikuchi River outside Yamaga — a 2015-vintage complex with lodging, a park and a bath, and the Kikuchi Castle earthworks 3km away. From there the route crosses the city and climbs into Misato, where Samata no Yu keeps its bath open to 21:00 and the old Kumanobi railway tunnel survives as a walkable 'time tunnel' a few hundred metres from the car park. Day two runs up the Kawabe valley to Itsuki, a village best known for a lullaby and for having been rebuilt above the waterline of a dam that was finally cancelled; the station's bath looks out over the new village. The last leg crosses to the coast at Ashikita, where Oono Onsen keeps its bath running to 20:00 — close enough to the Ashikita interchange to make a late finish practical.

Route tips
- Confirm last entry rather than closing time: Samata no Yu stops admitting at 20:30 for a 21:00 close, and Oono Onsen shuts at 20:00.
- Kamoto and Samata no Yu both have rooms on site — the natural split is a night at one of them, which keeps each driving day under three hours.
- The Itsuki leg is a mountain road along the Kawabe River with few shops; buy lunch at Misato or eat at the Itsuki station restaurant, which closes mid-afternoon.
- Yamaga's own historic bathhouse and the Yachiyoza kabuki theatre are 15 minutes from the first station — the obvious half-day add-on if you start in the morning.
