Yushima no Yu: An Outdoor, Source-Flowing Bath in Hayakawa
Yushima no Yu’s outdoor pools use source water; adult entry is ¥700 for non-residents, usually 10 a.m.–6 p.m., weather permitting.
Checked: September 27, 2026
Yushima no Yu keeps things simple: outdoor pools, mountain air and spring water without added water or reheating. There is no indoor main bath listed, so rain, wind and cold are real trade-offs rather than minor details. If you want a sauna, indoor pool or an all-weather spa, choose somewhere else.
Hours, rates and the Monday rotation
| Item | Current listing |
|---|---|
| Adult day admission | ¥700 |
| Child admission | ¥300 |
| Regular hours | 10 am–6 pm |
| July and August | 10 am–7 pm |

| Bath layout | All outdoor; rock bath on one side, wooden and stone baths on the other |
The two bathing areas rotate between men and women on Mondays. The operator’s public listing does not promise which side will be assigned on a particular visit, so check if a specific bath layout matters to you.
Hayakawa Town’s 2026 spring table lists a sodium-sulfate/chloride spring at 47°C and pH 9.2, supplied by source flow. The bathing temperature may differ from the source temperature, particularly in an outdoor pool exposed to the weather.
A short soak or a longer break?
The basic ¥700 ticket suits a straightforward bath stop. The ¥1,500 day-rest plan includes admission and access to the shared rest area from 10 am to 3 pm.
There is also a daytime cottage option listed at ¥1,500 per adult, also including bathing, but the operator notes it may be unavailable when cottages are occupied. Confirm before counting on private rest space.
This facility also has five self-catering cottages for overnight stays. They do not include meals, so bring food or plan where to eat before arriving; do not assume a full-service hotel restaurant is part of the bath visit.
The bus is the part to plan first
The nearest stop is Yushima no Yu on Hayakawa’s shared-bus route between Minobu and the Narada area. Service is infrequent, and the ride follows a long mountain road. Check departure times in both directions and look for road restrictions after heavy rain or snow. It is easy to spend longer getting here than in the bath itself, so build the outing around a confirmed return connection.
For a different day-use bath in the same town, compare Healthy Misato or Villa Amahata. The broader Hayakawa day-use guide separates visitor baths from inns that do not accept walk-ins.
