Hokkaido Onsen Guide: Best Hot Springs, Towns, and Tips

Published: 2026-09-20 / Updated: 2026-10-28 ・ 7 min read

Hokkaido onsen represent some of the most dramatic and mineral-rich geothermal waters in all of Japan, set against wild northern landscapes and heavy winter snowfall. Whether you seek the sulfuric volcanic calderas of Noboribetsu or a quiet forested river gorge outside Sapporo, Japan’s northernmost island offers an exceptional hot spring culture accessible to international travelers.

Because Hokkaido is geographically vast, planning an onsen trip requires understanding regional transit hubs, bathhouse etiquette, and the seasonal weather conditions that shape winter travel.

Top Onsen Towns in Hokkaido

Hokkaido features distinct volcanic regions, each producing spring waters with unique mineral compositions, colors, and histories.

Noboribetsu Onsen (登別温泉)

Located in southwestern Hokkaido, Noboribetsu is widely regarded as the island’s most famous onsen resort. The town sits directly above Jigokudani (地獄谷), or "Hell Valley," an active geothermal crater where steam vents, bubbling sulfur streams, and volcanic fissures create an otherworldly atmosphere.

Noboribetsu is unique for hosting up to nine different water varieties across its resort ryokan (traditional inns) and public day spas, ranging from milky-white sulfur springs to acidic alum pools.

• Travel Time from Sapporo: Around 1 hour and 15 minutes by JR limited express train to JR Noboribetsu Station, plus a 15-minute connecting local bus. Direct highway buses from central Sapporo take roughly 1 hour and 40 minutes.
• Best For: Travelers wanting classic volcanic scenery and large, multi-bath facilities.

Jozankei Onsen (定山渓温泉)

Nestled inside Shikotsu-Toya National Park along the Toyohira River gorge, Jozankei serves as the primary hot spring escape for residents of Sapporo. Founded in the late 19th century by a monk named Jozan, the town features dense forests that turn vibrant shades of red and gold in autumn and accumulate deep powder snow in winter.

The water here is predominantly clear sodium chloride spring water, which retains heat well.

• Travel Time from Sapporo: Approximately 60 to 75 minutes via the Kappa Liner express bus departing directly from Sapporo Station.
• Best For: Quick weekend trips, day trips without heavy luggage, and picturesque river views.

Toyako Onsen (洞爺湖温泉)

Perched on the southern edge of Lake Toya—a massive caldera lake that rarely freezes in winter—Toyako Onsen combines sweeping water vistas with active volcanism. Mount Usu, an active volcano located just behind the town, provides the geothermal energy that fuels the local baths.

Visitors can soak in outdoor baths (rotenburo) overlooking the lake, Nakajima Island, and Mount Yotei in the far distance.

• Travel Time from Sapporo: Around 1 hour and 50 minutes by limited express train on the JR Muroran Line to Toya Station, followed by a 20-minute local bus ride.
• Best For: Scenic lakefront views, walking trails, and summer fireworks displays.

Sounkyo Onsen (層雲峡温泉)

Situated deep inside Daisetsuzan National Park in central Hokkaido, Sounkyo sits at the foot of towering, columnar volcanic rock cliffs along the Ishikari River. The town serves as a high-altitude basecamp for summer hikers and a tranquil winter retreat during the Sounkyo Ice Waterfall Festival.

• Travel Time from Asahikawa: Roughly 1 hour and 30 minutes to 2 hours via local highway bus from Asahikawa Station.
• Best For: Mountain enthusiasts, alpine scenery, and quiet, off-the-beaten-path soaking.

Step-by-Step Onsen Etiquette for First-Timers

For travelers who have never experienced an onsen, the prospect of communal bathing can feel unfamiliar. The sequence of steps is straightforward and practiced universally throughout Japan.

1. Entering and Paying

Remove your outdoor shoes at the entrance (genkan) and place them in the provided shoe lockers. You will either purchase an entry ticket at an automated vending machine or pay an attendant at the reception desk (front).

Day-use admissions generally range from 600 to 2,000 yen depending on the luxury of the facility. If you did not bring your own towels, request a rental towel set (face towel and bath towel) at this stage.

2. The Changing Room

Pass through the curtains indicating your gender:

• Men: Typically marked with the character 男 (otoko) and blue fabric.
• Women: Typically marked with the character 女 (onna) and red or pink fabric.

Inside, place all clothing, accessories, watches, and personal electronics into a clothing basket or coin-operated security locker. You must enter the bathing area completely unclothed; swimsuits, underwear, and footwear are strictly forbidden. You may carry only your small modesty towel into the washing room.

3. The Washing Station

Before stepping into any communal bath, you must wash and rinse thoroughly.

• Locate an open washing stall equipped with a plastic stool, basin, body soap, and shampoo.
• Sit down on the stool while showering so soap water does not splash onto neighboring bathers.
• Rinse all soap completely off your skin and hair before moving to the pools.

4. Soaking in the Baths

Step slowly into the bathwater to allow your body to adapt to the temperature, which typically ranges between 40°C and 43°C (104°F to 110°F). Keep these points in mind:

• Do not submerge your head or hair in the water; long hair must be tied up in a bun or secured with a hair band.
• Never place your small washcloth inside the bath water. Rest it folded on top of your head or place it on the rock edge beside you.
• The onsen is a place of quiet relaxation; avoid swimming, diving, or talking loudly.

5. Exiting the Bath

Before re-entering the carpeted or tatami dressing area, wring out your small washcloth and wipe down your body as thoroughly as possible. Damp floors in the changing area are a hazard and considered poor etiquette.

Drink plenty of fresh water from the coolers located in the dressing lounge immediately after your bath to avoid dehydration.

Tattoos and Private Baths

Historically, Japanese public baths have maintained strict bans on visible body art. In Hokkaido, policies differ by facility. Large international resort hotels in ski towns like Niseko and Rusutsu often permit discreet tattoos or sell waterproof flesh-colored cover stickers at the front desk. However, many municipal and traditional ryokan baths still strictly prohibit visible tattoos of any size.

If you have extensive body art or prefer complete privacy, look for facilities offering kashikiri-buro (貸切風呂), which are private baths reserved by the hour, or book a ryokan room with an attached private outdoor bath (rotenburo tsuki kyakushitsu). These private options bypass all public restrictions entirely.

What to Bring: Day-Use Checklist

• Small face towel: Used for drying off before re-entering the changing room.
• Large bath towel: Used in the locker room after the soak.
• 100-yen coins: Many shoe lockers and clothes lockers require a 100-yen deposit, which is refunded when you unlock the door.
• Cash: Small rural facilities and ticket kiosks frequently do not accept international credit cards.
• Moisturizer: Mineral-heavy volcanic waters, especially sulfur-based springs, can dry out sensitive skin.

Planning Your Hokkaido Transit

Hokkaido covers vast distances, and public transit schedules operate less frequently than those on Japan's main island of Honshu. Winter weather frequently leads to train speed restrictions or highway closures due to heavy snowfall and blizzard conditions.

When routing your journey, reference schedules and rail pass validities through official resources like the Japan National Tourism Organization and local operators such as JR Hokkaido.

If traveling between December and March:

• Allow a minimum of one to two hours of buffer time when connecting back to major airports such as New Chitose Airport (新千歳空港).
• Confirm your hotel shuttle bookings in advance; many onsen ryokan run free or low-cost private shuttle buses between Sapporo Station and their front doors for overnight guests.
• Check day-use bathing hours online ahead of time, as many ryokan open their public baths to non-staying guests for only a limited window each afternoon.

FAQ

Q. Can you visit a Hokkaido onsen if you have tattoos?

A. Tattoo policies vary widely depending on the facility, though private baths provide an accessible option everywhere. While traditional public baths often prohibit visible ink, many modern resort hotels now offer tattoo-covering patches or rent private family baths (kashikiri-buro) by the hour. Always verify the specific rules on the official website of your chosen bathhouse before entering.

Q. How do you get from Sapporo to Noboribetsu Onsen?

A. You can reach Noboribetsu Onsen from Sapporo in roughly one to two hours using direct highway buses or JR trains. Taking an express train on the JR Muroran Line to Noboribetsu Station followed by a 15-minute local shuttle bus is the most reliable rail route. Highway express buses also depart directly from Sapporo Station straight to the hot spring village.

Q. What should you bring to a day-use hot spring in Hokkaido?

A. You only need basic personal items, as most commercial onsen provide communal wash supplies. Bring a small washcloth or face towel, cash for entry lockers and ticket machines, and a coin (usually 100 yen) for returnable shoe and luggage lockers. Larger bath towels can almost always be rented or purchased at the front desk for a modest fee.
