Located in Taketa City, Nagayu Onsen is often referred to as "Japan's number one carbonated onsen." Rich in carbon dioxide, the waters here create delicate bubbles that cling to your skin during a soak, providing a pleasant and gentle stimulation. This unique feature promotes blood circulation, alleviates fatigue, and helps relieve cold sensitivity. The onsen also offers drinkable carbonated water, which is believed to stimulate digestive health and enhance metabolism. Scattered throughout the onsen town are several spots where you can taste the carbonated spring water while enjoying a leisurely stroll.

This area has a long history as a popular therapeutic onsen destination. Its relatively cool water temperature, characteristic of carbonated springs, allows for extended bathing sessions, making it ideal for slow and relaxing therapeutic stays. Situated in a lush, natural setting, Nagayu Onsen features inns and bathhouses along the river, providing a serene environment for exploration and relaxation. Take time to wander through the charming town and discover the unique appeal of this exceptional carbonated onsen.
