Nagayu Onsen: Day-Use Hot Spring Baths & Prices (Oita)

Rising in the mountains of Taketa City, Nagayu Onsen is a celebrated spring known for its high concentration carbonated water, a rarity in Japan. When you soak, fine bubbles cling to your skin, giving a distinctive fizzing sensation. There is also a long tradition of drinking the water here, making it an unusual village where you can enjoy the spring both inside and out.

Highlights

The water, rich in carbon dioxide, sometimes takes on a brownish tint from its iron content. The Ramune Onsen Kan, designed by the architect Terunobu Fujimori, is a signature facility using a spring of around thirty two degrees rich in free carbon dioxide, where you can experience a distinctive carbonated bath. Along the river there is also the free open air bath Gani no Yu, where soaking while listening to the babbling stream feels wonderful. Drinking fountains are provided as well, where you can taste the spring water with its distinctive flavor.

Enjoying the Seasons

Spring brings fresh greenery and autumn dresses the valley in beautiful foliage, letting you take in nature from the riverside open air baths. In winter the warmth of the carbonated water reaches deep into the body and is said to keep you from chilling afterward. You can enjoy the baths alongside the changing scenery of the mountain village.

The water is a bicarbonate and carbon dioxide spring, and drinking it is said to benefit the stomach and internal organs. Access by car is convenient, and the location pairs well with sightseeing on the Kuju Highlands.

Practical Travel Notes

The carbonated springs are characterized by cooler sources in the thirty degree range, and the longer you soak, the more the bubbles cling to your skin, said to make the effect easier to feel. Since facilities such as the Ramune Onsen Kan and Gozenyu differ in temperature and carbonation, comparing two lets you enjoy the differences. The drinking water has a distinctive flavor, so follow each facilitys guidance. Allow two to three hours for bathing, drinking, and a riverside stroll. Combined with a Kuju Highlands drive or nearby nature sightseeing, it makes for a full day itinerary. Budget wise, day use bathing runs from a few hundred yen to around one thousand yen.

A Quick Tip

For carbonated springs, soaking slowly in cooler water is said to be most effective. Drinking the water follows different customs at each facility, so taste it by following the local guidance.
