♨️ Onsen with Babies: Hokkaido Hot Springs

Where to Go — Jozankei vs. Noboribetsu

There are two main hot-spring areas near Sapporo. With two babies and two families together, the easiest plan is to make Jozankei your base since the trip is short, and add a day trip to Noboribetsu if you have time to spare.

• Jozankei (定山渓): About 1 hour by car or bus from central Sapporo. A family-friendly hot-spring resort known as 'Sapporo's back parlor.' Comfortable for both a day trip and an overnight stay.
• Noboribetsu (登別): About 1.5–2 hours from Sapporo. One of Hokkaido's signature hot springs, famous for its 'Hell Valley' and remarkably varied water types (up to 9 different springs). The distance makes an overnight stay advisable.

Bottom line: if your baby's condition comes first, stay one night in Jozankei; if you want to take in a wider range of scenery and hot springs, add Noboribetsu.

The 'Reality' of Onsen with Babies — You Can't Use the Public Baths

This is the most important point. Many Japanese onsen public baths (shared baths) prohibit or restrict bathing for infants and toddlers who are still in diapers, because of hygiene and the risk of *nobose* (dizziness/heat exhaustion).

For our group: - Baby A (33 months): If out of diapers, the public bath may be possible depending on the facility — but always confirm the facility's rules. - Baby B (16 months): Still in diapers → the public bath is effectively off-limits. Use a family bath / in-room bath instead.

That's why both families feel most at ease going with a kashikiri-buro (private bath) or an in-room open-air bath (in-room onsen). Since it's a space just for us, there's no need to feel awkward even with a diaper-wearing baby or with tattoos.

General guidelines (based on official and medical information sites, for reference): - Avoid bathing newborns under 28 days old. - A baby's first onsen should be after 3–4 months, once they can hold their head up, and only when they're in good condition. - Because of hygiene and *nobose* risk, the shared public bath is relatively safe only after age 2, once out of diapers (facility rules take priority). - For water type, a low-stimulus alkaline simple spring at 40°C or below is the safest choice.

Our Picks — Kashikiri-buro & In-Room Open-Air Baths

For two families (4 adults + 2 babies) to use together, the key is to book a family bath with a roomy tub or a room with its own open-air bath. Jozankei has plenty of good options.

Examples of Jozankei family baths / in-room baths (prices and operations vary — confirm officially when booking): - Nukumori-no-Yado Furukawa (ぬくもりの宿 ふる川): A private bath (kashikiri-buro) is ¥2,200 (approx. ₩21,000) per room for 50 minutes, plus a per-person bathing fee on top. The private bath may be for overnight guests only, so be sure to confirm when booking. Day-use bathing (12:00–15:00, last entry ~14:30) is ¥1,500 (approx. ₩14,000) for adults / ¥750 (approx. ₩7,100) for elementary-school children / free for younger children. Request children's chairs and amenities when booking. - Yuraku Soan (ゆらく草庵): Every room has an onsen bath, plus several in-house private baths (free when vacant) — confirm usage conditions officially. - Hanamomiji (花もみじ): The family bath is equipped with a baby chair and baby soaps (confirm when booking). - Manseikaku Hotel Milione: Lists baby facilities such as a baby chair, baby bed, and diaper trash bin (confirm officially).

In Noboribetsu, booking a one-night stay at a ryokan with an in-room open-air bath lets you enjoy a stroll through Hell Valley plus the hot springs all in one trip.

Noboribetsu Hell Valley — A Winter Day Trip

How to get from Sapporo to Noboribetsu Onsen (fares and travel times vary — confirm officially before departure): - Highway bus (Donan Bus 'Kosoku Onsen-go', 高速おんせん号): About 1 hour 50 minutes to 2 hours from in front of Sapporo Station. One way is roughly ¥2,200–2,500 (approx. ₩21,000–24,000; figures differ by source). It is fully reservation-based, so booking at least 2 hours before departure is recommended. - JR limited express (Suzuran / Hokuto) + local bus: Sapporo → Noboribetsu Station in about 75 minutes, roughly ¥4,780 (approx. ₩45,000; base ticket + reserved-seat express ticket). As of the March 2024 revision, all limited-express trains within Hokkaido are fully reserved-seat (non-reserved seating has been abolished). From the station to the onsen bus terminal, a local bus takes about 15 minutes for ¥350 (approx. ₩3,300).

Hell Valley (地獄谷) is just a short climb up the hill from the bus terminal. The walking path is fitted with a boardwalk, but in winter it gets very slippery with ice, and some of the upper paths may be closed. For babies, a carrier/hip seat plus crampons for adults are recommended.

Day-use bathing (*higaeri*) is also available (confirm fees and hours officially). - Dai-ichi Takimotokan (第一滝本館): Day-use bathing is ¥2,250 (approx. ₩21,000) for adults / ¥1,100 (approx. ₩10,000) for children, 9:00–18:00. Entry from 16:00–18:00 is ¥1,700 (approx. ₩16,000) for adults / ¥825 (approx. ₩7,800) for children. The largest ryokan closest to Hell Valley.

Onsen Etiquette & Tattoo Policy

The basic etiquette is the same whether it's a shared bath or a family bath. It's good to explain it to the kids in advance, too.

• Wash before entering: Before getting into the tub, rinse your body with *kakeyu* (かけ湯) or wash thoroughly in the shower.
• Don't dip your towel in the water: Place the small towel on your head or leave it outside the tub.
• Keep your hair out of the water: Tie up long hair.
• No photography: Phones/cameras are forbidden in the changing room and bath area (privacy).
• No running, stay quiet: The floor is slippery. Always hold babies' hands and move slowly.

Tattoo policy: Many shared public baths restrict bathing for those with tattoos. That said, Dai-ichi Takimotokan states that it allows bathing with tattoos (re-confirm before visiting), and in any case, using a kashikiri-buro / in-room bath lets you enjoy the springs regardless of tattoos. Since our group focuses on family baths, this makes things easy on that front too.
