Tucked away in the mountains of Nagano Prefecture, Shibu Onsen is a nostalgic hot spring town where cobblestone streets, wooden ryokan inns, and the gentle scent of sulfur evoke Japan’s ancient spa culture.
Famous for its nine public baths and traditional atmosphere, this onsen village invites travelers to experience the Japan of a bygone era — a world of yukata robes, wooden geta clogs, and steaming bathhouses beneath the mountain mist.
Just minutes from the famous Jigokudani Snow Monkey Park, Shibu Onsen blends natural beauty, historic healing waters, and authentic local hospitality, making it one of Japan’s most atmospheric and culturally rich hot spring destinations.

A Thousand Years of Healing History
The origins of Shibu Onsen date back over 1,300 years, to the Nara Period (8th century), when a wounded warrior is said to have discovered its curative hot springs.
During the Edo Period, the town flourished as a rest stop for samurai and monks traveling along the Zenkoji Kaido route.
The area’s mineral-rich waters became famous for treating nerve pain, fatigue, rheumatism, and skin conditions, and many people came to “take the cure” by bathing in its multiple springs.
Even today, local residents continue this tradition, visiting the baths daily as part of their lifestyle and community ritual.
The Nine Public Baths (九湯めぐり – Kyu-tō Meguri)
One of the highlights of Shibu Onsen is the “Nine Bath Pilgrimage”, a unique experience where visitors can soak in nine different public baths, each fed by a separate natural spring and believed to offer specific health benefits.
Each bath is small, cozy, and steeped in tradition — and every one has a number carved into its wooden entrance.
-
Ichino-yu (一の湯) – Eases gastrointestinal ailments.
-
Nino-yu (二の湯) – Relieves fatigue and helps muscle recovery.
-
Sanno-yu (三の湯) – Promotes smooth skin.
-
Yonnno-yu (四の湯) – Good for arthritis and neuralgia.
-
Gono-yu (五の湯) – Aids digestion and blood circulation.
-
Rokuno-yu (六の湯) – Helps with high blood pressure.
-
Nanano-yu (七の湯) – Improves joint pain.
-
Hachino-yu (八の湯) – Relaxes the body and mind.
-
Kono-yu (九の湯) – The most sacred, believed to bring spiritual and physical renewal.
Only guests staying at local ryokan receive a special wooden key that grants access to all nine baths.
Locals say that bathing in all nine brings good fortune and long life — a ritual known as “九湯巡り” (Kyu-tō Meguri).
Walking the Town in Yukata
Part of the charm of Shibu Onsen is simply wandering its narrow lanes in a yukata (cotton robe) and geta (wooden sandals), moving from one bathhouse to another.
The town is lined with over 30 ryokan, many over a century old, their wooden façades glowing warmly under paper lanterns at night.
Steam drifts from vents in the street, and the rhythmic clack of geta on stone adds to the timeless atmosphere.
Everywhere you go, you’ll find onsen symbols, guardian statues, and hand-carved signs, preserving the aesthetics of Japan’s Taisho and early Showa eras.
Staying in a Traditional Ryokan
Shibu Onsen’s ryokan are among the most traditional in Japan, offering tatami rooms, futon bedding, and kaiseki (multi-course) dinners featuring local Nagano cuisine.
Many inns, such as Kanaguya Ryokan, are historical landmarks themselves — some claim to have inspired the bathhouse designs in Studio Ghibli’s “Spirited Away.”
Guests typically bathe in their inn’s private baths before venturing out to complete the nine-bath pilgrimage.
At check-in, you’ll receive:
-
A yukata and obi belt for wearing around town.
-
A wooden key to the public baths.
-
A bath towel and small map showing each bath’s location.
Some ryokan also offer private open-air baths (rotenburo) with views of the surrounding mountains — especially beautiful in winter.
Seasonal Beauty
Shibu Onsen’s atmosphere transforms dramatically with each season:
-
Spring: Cherry blossoms bloom along the Yokoyu River, framing the town’s bridges and ryokan.
-
Summer: Lantern festivals and cool mountain breezes make evening strolls magical.
-
Autumn: Maple trees turn the valley vivid red and gold.
-
Winter: Snow blankets the rooftops, steam rises from the streets, and the world seems to slow down — a quintessential Japanese winter scene.
Winter also brings visitors heading to the nearby Jigokudani Snow Monkey Park, where wild monkeys bathe in natural hot springs — one of the world’s most iconic wildlife spectacles.
Local Cuisine
The cuisine of Shibu Onsen is deeply connected to the region’s mountains and pure water. Popular local dishes include:
-
Shinshu Soba (buckwheat noodles): A Nagano specialty served with wasabi and dipping sauce.

Oyaki Dumplings: Handmade buns stuffed with seasonal vegetables or sweet bean paste.

Bathing in Shibu Onsen follows traditional Japanese customs:
-

-
No swimsuits. Bathing is done nude.
-
