About this spring
Hyotan Onsen sits in Beppu's Kannawa steam district and ranks among the city's most beloved public bathhouses. The facility draws on seven separate spring waters and brings them together across a range of bathing options, including a hot-sand bath, a waterfall pool, private family rooms, and an open-air rotenburo, all within a single complex surrounded by rising geothermal steam. It is the only onsen in Japan to have received three Michelin Stars.
Highlights
History
In 1911, a man named Junsaku dug a hot spring on his own land with one purpose: relieving his wife's chronic arthritis.
The water proved effective, and word reached the neighbors, who began coming to use it. By 1922 the family had converted the operation into a commercial bathhouse under the name Hyotan Onsen. The gourd shape of the original rock bath was deliberate. Junsaku admired Toyotomi Hideyoshi, whose personal emblem was the gourd, and he carved the first bath in that form as a tribute. In 1927 an eighteen-meter observation tower called the Hyotan Pavilion was constructed on the grounds. Junsaku gathered bent trees from around the country to build it in the same gourd silhouette. Beppu was at that time cementing its standing as Japan's foremost hot spring city, and Hyotan Onsen grew alongside that rising reputation.
Local guide
The bus ride from Beppu Station into the Kannawa district takes about twenty-five minutes, and you spend most of it watching white steam columns rise from vents in the road and sidewalks, sometimes right between parked cars. By the time you step off at the Kannawa stop and walk three minutes east, the air has a faint sulfurous edge and the whole neighborhood feels like it is sitting on top of something alive. That is the feeling Hyotan Onsen runs on.
The facility opened in 1950 and earned its name from the distinctive gourd-shaped outdoor pools at its entrance, hyotan being the Japanese word for gourd. What makes this place genuinely unusual, even by Beppu's crowded standards, is the range of water on offer in a single visit. Seven different spring types flow through the complex, each with its own mineral character and temperature. The main baths carry a mildly alkaline sodium-chloride water at around forty-two to fifty-five degrees, clear and almost silky against the skin. The bamboo cooling system the owners built drops the source temperature from one hundred degrees to a usable range without diluting the water with tap, so what you are soaking in is pure Kannawa spring from start to finish.
The sand bath, taki-no-yu waterfall pool, and steam bath are all separate experiences within the same grounds, and it is common to spend two hours working through them in sequence. The sunamushi here uses sand from Beppu Beach only, heated by geothermal steam rather than direct fire, which keeps temperatures moderate enough that first-timers can stay buried comfortably for fifteen minutes without feeling dizzy or overheated. You put on the provided cotton yukata, lie down on the dark sand, and a staff member shovels it over you up to the neck. The weight is surprising, close to a firm, warm pressing sensation over your whole body.
The most specific thing about Hyotan Onsen is the stone drinking fountain in the courtyard, shaped like a gourd, where the spring water flows directly from the source. The water is safe to drink, though it has a faint mineral edge. Locals call it lucky spring water and claim drinking it on days that fall on the number eight brings good fortune. Whether you believe that or not, standing in the steam-thick courtyard of a facility that has won three Michelin Green Guide stars seven consecutive times, cupping your hands under a gourd-shaped spout to taste the water that also heats the sand bath, is about as Beppu as Beppu gets.
Mineral chemistry
Water character inferred from mineral type — verify on site.
Sodium chloride springs, essentially natural saltwater baths, are celebrated for their warming and moisturising effects. The salt forms a thin film on the skin that slows moisture evaporation, keeping skin hydrated longer than a freshwater bath.
Those with high blood pressure or heart conditions should consult a doctor before bathing, as the warming effect increases circulation. Avoid immersing open wounds.
Calcium chloride springs share the heat-retaining property of sodium chloride springs but with a stronger warming effect. Prized for muscle and joint relief.
The strong warming effect means those with cardiovascular conditions, high blood pressure, or pregnancy should limit soak duration and consult a doctor if in doubt.
Simple thermal springs have lower dissolved mineral content but are valued for the pure therapeutic effect of heat immersion itself — easing muscle tension and improving circulation. Considered the gentlest introduction to hot spring bathing.
Standard precautions apply: avoid bathing within 30 minutes of eating, keep soaks to 10–15 minutes for first-timers, and hydrate before and after.

FREEThe valley occupies the center of Noboribetsu Onsen in Hokkaido. Jigokudani translates as Hell Valley. The crater covers 11 hectares and releases roughly 10,000 tonnes of hot spring water each day. Fumaroles vent steam across the floor of the valley, boiling pools bubble at the surface, and the surrounding cliffs carry heavy mineral staining. A walking path winds through the area in about 20 minutes and is open to all visitors at no cost. It ranks among the most striking landscapes accessible on foot anywhere in Japan.
Dogo Onsen ranks among the oldest hot springs in Japan, with written records documenting its use for more than 1,300 years and oral traditions pointing back considerably further. The landmark Dogo Onsen Honkan is a three-storey wooden bathhouse finished in 1894, widely credited as the inspiration for the bathhouse depicted in Studio Ghibli's Spirited Away. The spring water is mildly alkaline and has long been valued for its ability to soften and smooth the skin.
Beppu is the most geothermally active city in Japan, with more than 2,900 hot spring vents located within the city limits and eight distinct thermal spring zones collectively known as the Beppu Hatto. The variety on offer is wide, ranging from grand hotel bathhouses to modest neighborhood public facilities to the celebrated Hells, a collection of brilliantly colored boiling pools scattered across the city. The Hells run far too hot for bathing, but they draw visitors who come to walk among them and take in the spectacle.
Arima Onsen sits in the hills above Kobe, close to Mount Rokko, and ranks among the oldest hot spring towns in Japan. The town draws visitors for two entirely different spring types that coexist within its compact footprint. Kinsen is the iron-rich golden water that stains surrounding rocks a rusty orange, while ginsen runs clear and carries both carbonation and mild radioactivity. Few other onsen destinations in Japan bring together two such distinct water types within a single small town.

A peaceful artsy onsen town at the foot of Mt. Yufu in Oita Prefecture. The town is known for boutique galleries, craft shops, and ryokan with private outdoor baths. Lake Kinrin sits at the heart of it all. On quiet mornings, steam rises off the lake's surface in a way that seems almost designed to make you stop and stand still.
Set on a wooded slope in Beppu's Myoban district, this resort draws visitors for its yunohana, a term meaning hot spring flowers, which are white crystalline deposits that collect on surfaces where steam from the springs cools and condenses. The spring water itself is strongly sulfurous and acidic, rising at high temperatures from one of the eight volcanic source zones that make up Beppu Hatto.
