Misasa Onsen Ryokan Ohashi
三朝温泉 旅館大橋
A long-established inn of Misasa Onsen whose 1929 building is almost entirely registered as a national tangible cultural property. The water comes from its own spring and a self-flowing source, running full flow-through, and is a simple weakly radioactive radon spring. The famous cave bath switches between men and women by hour, so during the day-bath window there are times when men cannot enter it. Day bathing is 1,500 yen for adults (tax included), accepted from 16:00 to 20:00, paid in cash. It stands at the entrance to the spa street, a pleasant walk past the Mitoku river and its bridge.

Why go
- A building registered almost whole as a cultural property
- Full flow-through from its own and self-flowing springs
- A simple weakly radioactive radon spring
Bathing in a registered cultural property
The building was raised in 1929 and almost the whole of it is registered as a national tangible cultural property. Corridors, stairs and joinery are still used as they were, so the walk to the bath is itself worth seeing. Because alterations are restricted, there are steps and the route to the bathing rooms can be long, so tell the inn when booking if walking is difficult.
The cave bath and its hourly switch
The bath cut through the rock is the symbol of this inn. It alternates between men and women by the hour, and on days when 15:00 to 21:00 is allotted to women, men cannot enter. Day bathing is accepted from 16:00, which overlaps that window, so if the cave bath is the reason for the visit, ask which side is open before you go.
How day bathing works
Day bathing is accepted from 16:00 to 20:00 at 1,500 yen for adults, tax included, and 500 yen for children aged 3 to elementary school. Only cash is taken, so bring some. On busy days and during cleaning or maintenance the counter may be closed, so calling on the day is the surest check. It stands along the road that crosses the Mitoku river into the spa street, which makes it easy to combine with a walk.
Before you go
- No official tattoo policy is published — ask at reception.
