Sukayu Onsen is situated on the western foot of the main peak of the Hakkōda Mountains, Mount Odake, which also happens to sit along the ring of fire, and is a high-altitude hot spring located approximately 900 meters above sea level. Surrounded by beautiful scenery and bountiful lands all around, in the spring, high-altitude plants blossom into beautiful flowers, and you can enjoy the brilliant colors of the Momiji in autumn.

Besides this, as one of the places on earth well known for its immense snowfall, Sukayu is also a Mecca for skiers in winter. With snowfall exceeding five meters in some years, there is abundant high-quality snow, attracting skiers from Australia, Europe, and the rest of the world.

The origins of Sukayu Onsen date back about 300 years, to 1684. When local hunters were chasing a deer which they had injured into the mountains, the deer bounded up into the mountains, and the hunters saw it make a lively escape.

They thought it strange that an injured deer should behave like this, and on further investigation, they found the hot spring flowing. After that, the hot spring became known as "Shikayu," which means "deer springs," known for its medicinal properties, and its name was later changed to "Sukayu."

After that, the locals built small houses near the source of the spring waters, and from being a hot spring initially open to foragers and hunters in the mountains, the gentle medicinal properties of the waters together with the alpine climate gained the place a name as a "yujiba" in Japan, a hot spring specifically for healing ailments.

Over the years, ryokan and other accommodations for visiting the hot springs for health reasons increased in number, and in 1954, as a hot spring area with a gentle environment, it was registered as the first Nationally Protected Hot Spring.

The "Su" in "Sukayu" refers to acid, and is a reference to the strongly acidic waters of this hot spring. The acidic sulfurous waters are said to have positive effects on rheumatism, neuralgia, and digestive issues, amongst other healing properties.

Even now, many people visit these famous baths for medicinal reasons. Starting from the 260-square-meter large mixed bath, the "Hiba Sennin Furo," there are a total of five baths available, which have continued to heal visitors over the years.

Though Sukayu Onsen is among the most famous onsen in Japan, it is located deep within the mountains of Hakkōda, so do check access information before going down.

If you're coming from Tokyo or Osaka, it is recommended that you take either take a plane or bullet train to Aomori, and switch to a bus from there. However, when coming by plane, there is no direct bus from Aomori Airport to Sukayu, so you'll have to go to Aomori Station or Shin-Aomori Station, and from there, you can take the JR bus to Sukayu Onsen, which runs all year round including in winter.

Incidentally, if you will be staying at Sukayu Onsen-juku, you can make a reservation for the shuttle bus to come and pick you up from Aomori Station, so do make use of this service if you'll be spending the night there.

When taking the JR bus:
-From Aomori Station east exit to Sukayu Onsen: one hour and ten minutes
-From Shin-Aomori Station east exit to Sukayu Onsen: one hour and twenty minutes

Though rental cars are also recommended, take extra care when driving in winter, as the mountain roads have many curves and are slippery. Four-wheel-drives and tire chains, amongst other anti-slip measures, are a must.

On top of this, in winter, some areas are gated shut at night, and depending on the weather, some areas may remain closed to traffic during the day. Particularly in winter, do check up on information beforehand, and if you're not used to driving on snowy roads, do make use of the buses instead.

After traversing the dangerous roads of Hakkōda, a retro wooden building awaits you at Sukayu Onsen. With the giant words "Sukayu" written on the signboard outside, you can feel a sense of history from it, and it has you brimming with anticipation as you step inside.

The interior of the building is very spacious, and is reminiscent of the accommodations for "yuji-juku," meant for people staying at the hot springs for health reasons. Buy your tickets from the vending machines and head to the reception at the front desk, and you're set to enter the springs.

Incidentally, bath and face towels are provided, so you don't have to bring anything with you when going in. Besides this, the Hiba Sennin Furo is a bath only meant for soaking in, so a washing area is not included. Soap and shampoo are strictly prohibited there too, so do take note.

Once you've changed out of your clothing, head to the Hiba Sennin Furo. Once you head into the bath area, the wide-open space and white steam covering the baths jumps out at you. As the name implies, the Sennin Furo, which means "thousand-person bath," seems large enough to accommodate one thousand people.

It is made of cypress wood from Aomori prefecture, and without a single pillar used in its construction, there is an overwhelming sense of presence, making you feel like you've become one with nature.

Before you make use of the baths, there are two points to take note of. Though the Hiba Sennin Furo is technically a mixed bath, the left side is reserved for the gents, while the right side is for the ladies.

Though there isn't a separation available, there is an area which the men are requested to refrain from entering, so that the ladies may enjoy the baths with peace of mind too. For the gents, do mind your manners when entering the baths.

Besides this, special clothing sold on-site for the ladies that can be worn into the baths are available too, so it's recommended to make use of it. As there are ladies-only timings reserved for the bath as well, from 8:00 a.m. to 9:00 a.m. and 8:00 p.m. to 9:00 p.m., those who would prefer to avoid the mixed baths can go in during those timings as well.

Another point of note is that the bath waters are very acidic, with a pH of 1.7, so when you enter the bath, you'll feel a tingling sensation on your skin. As those with sensitive skin may get inflammation, it's recommended to limit your time in the bath to ten minutes at most and not rub your body when soaking in the waters.

After you've finished your soak there, try a dip in the Netsuyu, which is right in front. The name translates to "hot bath." Though it may seem like a bath with very hot water, it's actually at a comfortable temperature that's easy to enter and warms your body up nicely. With slightly cloudy waters with a smooth feel on your skin, soothe your body in this historically famous bath.

The next bath is deeper inside, the "Shiburokubu-bo-Yu." The name means "the bath of four parts and six parts" and refers to how close the water temperature is to your body temperature. If the Netsuyu is a ten on the scale, this bath is four to six.

The spacious bath interior has an open feel, and with bath waters slightly hotter than the Netsuyu, you can feel yourself comfortably sweating.

After you've washed off the sweat from the baths with cold water, head to the Yutaki. With forceful streams of water, you can concentrate the waters on your shoulders and other problem areas for a massage.

The trick is to allow the strength of the water striking your problem areas to gradually increase in strength, allowing you time to get used to the force of the water.

Finally, head into a hot bath one more time, to warm up your body. Your body will have the slight smell of sulfur left on it, and you'll find your body becoming lighter as a result of the special properties of the bath waters you've been soaking in.

To wrap things up, head back to the building and have some spring water from Hakkōda to replenish the water lost by your body.

Inside the building, besides the Hiba Sennin Furo, is a small bath called the Tama-no-Yu. The bathing area here is separated into small bathing areas for males and females, so ladies can enjoy soaking with peace of mind as well, and you can enjoy spring waters from yet another different source from the Sennin Furo.

A washing area is available, with shampoo, conditioner, and body soap provided, so those who would prefer to have a proper clean-up are recommended to wash up here.

The Sukayu Onsen-juku is comprised of a "ryokan-tō,” with Japanese-style and western-style rooms, as well as a "yuji-tō,” for guests coming for "yuji,” where they use the bath waters to sooth their ailments and illnesses. There is a dining area near the yuji-tō, and kitchen facilities for making food for extended stays are available too.

Especially in winter, there are many guests who come for yuji, and many foreign visitors who come for skiing often make use of the yuji facilities too.

Besides this, the ski season is open from the beginning of December to mid-May, allowing you to enjoy it for about half a year, and the 5-kilometer-long long course with high-quality powder snow is critically acclaimed as well.
