About this spring
Katayamazu Onsen sits on the shore of Lake Shibayamagata in the Kaga district of Ishikawa Prefecture. The lake is known to pass through seven distinct colors at different points throughout the day. Among the four Kaga Onsen towns, Katayamazu is the youngest, though the broader region carries more than 1,300 years of bathing tradition.
Highlights
History
In 1653, the feudal lord of the Daishoji Domain observed waterfowl congregating repeatedly at a single point on the lake surface.
The birds were drawn by heat rising from the lakebed, and the lord recognized this as a sign of a spring below and ordered the site to be excavated. The drilling methods of the period were not capable of reaching the source, however. It was not until the Meiji era that advances in drilling technology made it possible to finally bring the spring water to the surface. The reclamation of part of Lake Shibayama around the same period produced the land on which the present town was built.
Local guide
Coming from Kaga Station on the Hokuriku Shinkansen, you travel by bus for about twenty minutes through flat rice country before the road swings south and Lake Shibayama appears through the windshield, low and silver and hemmed in by low forested hills. Katayamazu Onsen lines the northern shore of the lake, a compact strip of traditional inns and bathhouses that face the water across a narrow promenade. The lake is not large, but it does something unusual. Locals say the surface changes color seven times a day as the light shifts and the wind moves across it, going from pale grey to deep blue to a flat copper at sunset. A fountain in the middle of the lake fires up thirteen times daily, a thin white column visible from almost any outdoor bath in town.
The spring itself was discovered by accident in 1653 when the daimyo of Daishoji, Maeda Toshiaki, was falconing near the lakeshore and noticed birds congregating over a patch of open water. Closer investigation revealed hot springs seeping up from the lake bottom. Access to those springs required more than two centuries of patience, and it was not until a major land reclamation project partially filled in the lake that the water became properly accessible for bathing. The spring is a sodium chloride type, and the water it produces is clear and noticeably heavy, with a mild saltiness you can taste if you get a mouthful. On your skin it feels dense and warming, the kind of heat that does not let go quickly.
The cultural artifact that catches you off guard in Katayamazu is a wooden building called Hanayakata, constructed in 1920 as a practice hall for the geisha and maiko who once entertained guests in the town's larger inns. No geisha remain in Katayamazu today, and the hall has been converted into a workshop space for visitors interested in tofu making or cloth dyeing, but the building itself is beautiful. The cypress floors and low practice mirrors speak to a period when this lakeshore town was considerably more fashionable than it is now.
From the outdoor baths of most hotels here you look directly out at Lake Shibayama and, on clear days, at the sharp white shape of Mount Hakusan rising behind the lake to the southwest. The Hokuriku coast gets its share of winter snow, and from a hot outdoor pool with snowflakes falling into the steaming water and the fountain catching what light there is in the middle of the silver lake, Katayamazu becomes a different place entirely. Come in December if you can manage it.
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.

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.

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.

Tsuru-no-yu is the oldest of the seven inns at Nyuto, set deep in a beech forest in Akita Prefecture. The main draw is a large outdoor mixed-bathing pool fed by opaque, milky-white sulfurous water. Many regard it as the most beautiful onsen setting in Japan. People come here to put some distance between themselves and the rest of the world for a while.

The village also contains world-class ski slopes, a pairing that is genuinely uncommon anywhere in the world.

Ito sits along the eastern shore of the Izu Peninsula, facing the ocean and ranking among Japan's most productive hot spring districts by volume. More than 1,500 individual springs feed the town's supply, together pushing out around 30,000 kiloliters of water each day. Palm-lined avenues, tropical parks, and botanical gardens set the tone here, giving Ito a resort atmosphere that reads as distinctly its own compared to inland onsen destinations.
