Nagayu Onsen 3
Nagayu Onsen is renowned for its rare carbonated hot springs, a unique feature even within Japan. When you soak in the water, tiny bubbles gently cling to your skin, promoting blood circulation and warming your body from the core. The spring water is also drinkable and has long been praised for its therapeutic effects, famously described as “effective to drink and soak, a remedy for the heart, stomach, and blood.” It continues to be a popular destination for therapeutic bathing (touji) and relaxation.
