YUKAWA HOT SPRING
Watch the water spill over the tub,
then settle into the quiet.
This day-use bath wins you over with fresh spring water, not elaborate decoration.
Kiyomon-yu is a day-use hot spring in Yukawa, Nachikatsuura. Water pours continuously from the source and flows over the rim of the bath, creating the simple scene that defines the place. Stop after walking the Kumano Kodo or visiting Nachi Falls, or use it as a calm final chapter after exploring Katsuura.

100% free-flowing source water, best enjoyed without rushing.
Five moments at Kiyomon-yuFive ways to unwind5 Ways to Enjoy

Watch the spring overflow
Fresh water pours in continuously and spills over the edge of the bath. The pleasure of a free-flowing onsen is visible before you even sit down.

Breathe in the mineral scent
A gentle sulphur scent and smooth-feeling water help the body loosen up. The soft feel of your skin afterwards is part of the appeal.

Choose a private family bath
There are three private family baths. A 50-minute session works well for families with small children and for travellers who prefer privacy.

Rest beside Yukashi Lagoon
Take a quiet break after bathing while looking toward Yukashi Lagoon. The pause before moving on is part of the experience.

End the day in hot water
Open from noon until 11:30 p.m., Kiyomon-yu is easy to visit after sightseeing or dinner and gives a Kumano day a gentle ending.

After Nachi Falls,
after the Katsuura coast, finish the day in hot water.
Take one plan off the schedule
Kiyomon-yu is open from noon until 11:30 p.m. That makes it easy to visit after a full day of sightseeing. Once you have bathed, all that remains is the short journey back to your accommodation.



SOURCE × LOCAL HISTORY
A spring woven into local life for about 1,500 years
Kiyomon-yu is introduced as one of Kishu’s historic hot springs, with a story stretching back roughly 1,500 years. The main attraction is not theatrical decoration but abundant, fresh source water. The baths are cleaned daily, the spring keeps flowing in, and the excess runs away over the rim. That honest rhythm is the reason to come.
