This summer, head to an Onsen. Set the water temperature just the way you like it.
“Isn’t an Onsen too hot in summer?” Many people think so.
What sets CaroCaro Tobaura Annex apart is that every guest room comes with its own Onsen, and upon request we can adjust the water temperature to your preference.
In summer, we recommend a lukewarm bath of around 38°C.
It’s gentle on the body, and before you know it, you’ll find yourself soaking for a long time.
Precisely because it’s lukewarm, you can take your time—this may be the true pleasure of an Onsen in summer.
[Why We Recommend Lukewarm Baths]
Water close to body temperature is also known as “neutral-temperature bathing” and is said to help activate the parasympathetic nervous system. Especially in hot summer weather, taking a long soak can help you Clear both mind and body.
