Artistic Onsen with Carbonated Water

Why name a hot spring building that was designed with sculptures and sections of charred lumber after a popular summer drink? The word lemonade is reportedly the source of the name for Ramune or Lamune Onsen (ラムネ温泉). Various springs in and around the remote town of Nagayu Onsen, Oita Prefecture, discharge naturally carbonated water that bubbles like a fizzy lemon drink. The artistic surroundings, the greenery, the bath design, and the unique water quality create an incomparable Japanese onsen experience.

Bring along your lover, special friend, or family members and rent one of the family rooms, or kazokuburo (家族風呂）for an intimate experience. We found a changing area, windows with a garden view, and two baths in our kazokuburo. The circular one is filled with constantly flowing carbonated water. It is not as hot as the rectangular bath, whose water comes from a different source.

Carbonation seems to disappear at very high temperatures. Slowly alternating between the two baths and a cold shower for an hour revitalized our bodies and mental outlook. When my wife and I bathed at Lamune, tiny bubbles briefly clung to our bodies before rising to the surface and popping. My friend, who often visits there, told me that the intensity of the carbonation varies daily. Natural hot springs are unpredictable, so visits to the same hot springs on different days may offer dissimilar experiences.

Lamune Onsen also has large communal gender-separated baths. Afterward, you can stroll around the building, which also has an art gallery on the premises, or walk outside and watch ducks in the nearby river. The air in the sleepy hot spring village is clean and fresh, just like the water, and there are many freshwater springs from which you can bottle water for free.  Several high-quality Japanese ryokans with traditional architecture are available if you want to spend the night. There are plenty of other hot springs. One of the most unusual ones is a free bath that is in the middle of a river and visible from many directions. The name is Ganiyu (ガニ湯).

The inside of the hot spring often has art displayed on the walls. A variety of local souvenirs are for sale, too. Souvenirs include t-shirts, bottles of local water, and Japanese sweets. There are also pamphlets about local happenings in Kyushu. Although Nagayu is far from the nearest big city, Oita, visiting is worthwhile. The Lamune Onsen homepage is in Japanese only.
