A sodium-calcium chloride spring — salty and heat-retaining, the kind of water that holds warmth well after the bath. Weakly alkaline and soft on the skin, it carries a fair amount of metasilicic acid (62 mg/kg) that lends a smoother feel. At the source the water shows a faint yellow tint and is slightly turbid.

Yukai-no-yu Neyagawa is a big day-use bathing complex in Osaka's Neyagawa with real hot-spring water outdoors: a three-tier rotenburo (露天風呂) where clear, faintly salty water spills from the top tub through the middle and lower ones. Indoors there's a hot bath, a milder one, and a carbonated bath, plus a stone-lined cold plunge and a jet bath with a notably strong current. Two different saunas sit side by side, a bright infrared dry sauna overlooking the baths and an herbal steam sauna built like a kiln. Beyond the baths it runs more like a day out than a quick soak: a free manga library, a bouldering wall, a fitness room, and a five-room rock-bed sauna, the ganbanyoku (岩盤浴), themed around salt, herbs, lava and loess, plus a lounge looking onto a garden to cool down in. A restaurant is open to non-bathers too. It's a casual neighborhood spot mostly used by local families for a whole afternoon.
A slightly tired but solid super-sento in the suburbs of Osaka
In the indoor area there are three baths with different temperatures:
1. Warm carbonated bath, 39.5°
2. Hot bath, 41.5°, with an electric corner in it that really massages your sides instead of bending you into an arch.
3. Hot bath, fairly deep, listed as 44-45°, but in fact it was 43.5°
There is a dry sauna, large and with lots of steps, so you can choose your own level of heat. The thermometer at chest level showed 82°, under the ceiling, 88°. The sauna comes with a large cool plunge bath, 17.5°
In the washing area there is the standard soap-shampoo-conditioner, but it seems that for summer they put menthol soap into the bottles, because after washing there was an unexpected feeling of freshness.
In the outdoor area there is a three-level outdoor stone bath, 41.5°, a reclining bath, 39.5°, three barrels, a standing bath, 90 cm, loungers, and chairs. There is also a herbal steam sauna, but it was not operating today, it said it was under maintenance.
In the relaxation area there is a restaurant, a kids' area with a small climbing wall (outside in the courtyard), fitness, and a computer corner. There is also ganban-yoku and massage.
Pros:
- large baths with a variety of temperatures
- inside and outside it looks fairly authentic
- 5 hours of parking when visiting the onsen
Cons:
- impossible to get there without a car, the shuttle from the station was canceled in June
- broken lockers in the changing room
- overall everything is old and tired, and with it being +37° outside, the air conditioners can no longer keep up with cooling the relaxation area, so it feels hot.
