HYOGO
Arima Onsen Taiko no Yu
A miraculous hot spring where ancient seawater from 6,000,000 years ago gushes up from 60 km underground
Head to Arima in the mountain foothills of Kobe’s Kita Ward, Hyogo Prefecture. The reddish-brown gold spring, the clear silver spring, and the lava sauna resonate together, quietly drawing you toward the memory of ancient seas and Rokko’s heat, deep into the steam.
The star is the reddish-brown gold spring, said to originate from seawater from 6 million years ago. The salty presence that lingers heavily on the skin speaks to the power of the water. The clear silver spring is gentle, and the more you alternate between the two, the more Arima’s depth comes into view. In the ultimate lava sauna, you are enveloped in the heat of Sakurajima lava and germanium, and in the dimmed löyly only the crystal at the center appears to float. The finishing touch is silver spring rock water. The mellow coolness of the natural hot spring quietly dissolves the heat away.
The weight of the water slowly sinking into travel memories
Arima is a tourist destination, yet the raw character of the water itself remains strong. What makes Taiko no Yu interesting is how it carries that power all the way to the cold plunge bath after the sauna.

One of the country’s finest collections of electric bathsI was amazed at how much a cold plunge bath could change the impression of a place. The spring water soaks into your body after the sauna, and even the sansaikyaki at the dining hall becomes part of the afterglow of the trip.

TOKYO
Spadium Japon
One of Kanto's largest spas where Tokyo's only "100 Famous Waters" spring and a natural hot spring shine
Clear spring water bubbling up in Higashikurume, Tokyo, and the colorless, transparent Musashino Onsen. Heat, bubbles, fragrance, and cool air overlap, making you forget the bustle of Tokyo.
The essence of Spadium Japon is remembered through water before heat. The same water source as the spring water chosen for Tokyo’s only selection in the “100 Famous Waters of the Heisei Era” gives the cold plunge bath its crisp, clear contours. In one carbonated bath, tiny bubbles tickle the skin, and even the cold air from falling ice becomes part of the performance. In the tower sauna filled with pine aroma, the hot blast from auto-löyly races up the tiered interior. The finish is the colorless, transparent Musashino Onsen. Its chloride and bicarbonate-rich water leaves the skin smooth again after sweating.
An afternoon that taught me Tokyo’s hidden strength through the chill of famous water
Even in a lively large-scale facility, the moment you step into the cold plunge bath, the air turns clear. The afterglow of famous water and the heat of aroma stayed in my body all the way home.

03
Lakeside heat to enjoy in privateAfter the sauna, I will never forget the crystal-clear feeling the moment I stepped into the cold plunge bath of Lake Shikotsu water. This is a place where the softness of the water reaches your skin before its coldness does. During the outdoor air bath, even the breeze off the lakeshore felt pure.


Saunas are everywhere in Japan. There are countless of them. What makes one unforgettable is not a place with the newest facilities, but a place where the right conditions come together in a way that can happen nowhere else. We chose these four criteria.

It is not just about being hot, or being new. Saunas that stay in the body’s memory for years share certain qualities.
The sea and the mountains are not something you can add later. Only a landscape that has existed there since ancient times can make a room truly one of a kind.
Today’s sauna is both architecture and a work of art. There are spaces where simply sitting there moves the senses.
Because it is a room cut off from reality, has a quietness been designed in which you can hear nothing but your own breathing?
A good stove creates good heat, and woods like keuro and red cedar create both insulation and fragrance.



Anagura Sauna is a place where, amid raw concrete walls and deep darkness, only the flame of the wood stove draws the outlines. The sound and scent of burning soften the heat. Yamagoya Sauna, by contrast, places the green of the park beyond its large windows, and each time water falls on the stacked stones, the air grows denser. The same firewood, yet a completely different expression. Darkness and light, two memories of wood fire.

A cold bath is the water of its place, plain and simple. How it is drawn and how it flows changes the way your body sinks in. It is not decided by coldness alone. Chosen by four measures, this is water you will never forget.

If it is only about being cold, anyone can make that. The cold baths that make you want to enter that water again had both a source and a way of being handled.
Natural groundwater, spring water, or hot spring water. There is a texture to water drawn from the land itself that nothing else can match.
Fresh water keeps pouring in, overflowing without pause. You can feel how fresh it is the moment you step in.
18 degrees or lower. And if there are cold baths with selectable temperatures, the experience itself changes.
You can step in as soon as you leave the sauna, without waiting. Water you sink into while worrying about everyone else's turn does not stay in memory.


The two cold plunge baths fed by the satoyama’s natural groundwater each have a different edge of chill. One is sharp, cutting off the heat; the other is soft, clinging to the skin. In one, fresh water pours in abundantly, and you can receive the falling stream over your head. Finish with outdoor air bathing, wrapped in the scent of the forest and open views, or step into the indoor air-bathing tent. Even in the spacious lounge, the afterglow of the cold never quite fades.
How little can we alter water that springs from underground before carrying it to the bath? Its color, scent, and texture are utterly different from place to place. We chose waters that have welled up since ancient times, using four measures.
The more water is carried, the more it thins and cools. That is why the day you encounter water as close as possible to its natural state is one you never forget.
Without added water, heating, or circulation, the water that springs forth fills the bath as it is and overflows as it is.
Colorless water turns golden when it meets the air. Water that rich is unmistakable the moment you step in.
Even after you leave the bath, the warmth stays deep in your core. We remember the water that lasted until the next morning's waking.
Its color, scent, and texture are utterly different from place to place. That water can spring only from that land.


Kinjō Onsen No. 2 spring fills the center of the large bath, while Kinjō Onsen No. 1 spring lies beneath the open air outside. The two natural hot springs continually overflow from their respective tubs. The indoor bath, in particular, is a deep brown whose richness is apparent at a glance. Once you sink in, it does not press with stimulation; instead, it gently loosens the whole body and seems to draw you toward sleep. Two vessels, taking in the water as it comes from the land.
After visiting 300+ hot springs and saunas, the curator kept only the places truly worth recommending. Everything beyond here is the full magazine.
