北海道・登別の温泉旅館おすすめ5選（本音のセレクト）

We open the Noboribetsu list with the ryokan that lands best for a first onsen trip — Noboribetsu Manseikaku, sat right in the heart of Hokkaido's most famous hot-spring town. The town is built around Jigokudani (Hell Valley), the sulphur-steaming crater whose water feeds the whole district, and Manseikaku has stood here for nearly a century. You get the full ryokan experience — tatami rooms, several baths to soak in, and careful Japanese meals. It is a 9-minute, 700-metre walk to Jigokudani and the shopping street, so you can see the town without renting a car. Guest scores land at 8.8, with location at 9.2 and the onsen itself at 9.0. From around $97 a night, we honestly think it is the right first stop for families and couples who want a complete ryokan in a good spot without rolling the dice.

For number two we wanted a pick for travelers watching the budget who still want the onsen — Park Hotel Miyabitei, a hot-spring hotel right in the Noboribetsu onsen town. It does its job well for the money: indoor and semi-outdoor baths to soak off the cold, clean Japanese-style rooms, solid service, and Japanese meals on offer. Rates start at roughly $91 a night, the most wallet-friendly on this onsen list, yet real guest scores sit at 8.9 — genuinely good value head to head with the price. You're in the heart of the onsen district, an easy walk to the sulphur-steaming Jigokudani (Hell Valley) and the shopping street. We recommend it honestly for families and couples who want the Noboribetsu onsen experience without paying ryokan-flagship money — the sweet spot between a proper soak and a sane bill.

Our #3 pick is the most polished onsen hotel on the list — Noboribetsu Grand Hotel, the classic grand hotel that has anchored the Noboribetsu spring district for years. The signature draw is its domed bath: a large soaking pool sitting under a handsome dome, with windows that look out onto a rock garden. Soaking under that roof feels different from a standard tub, and it is what pushes the onsen category up to a strong 9.4. Beyond the water you get full grand-hotel service, comfortable rooms in both Japanese tatami and Western bed styles, and a choice of kaiseki or Hokkaido buffet at dinner. The location is central — Jigokudani (Hell Valley) is a short walk away. Rates start around $109 a night and real guest reviews land at 9.2. We recommend it for couples and families who want an elegant, fully equipped onsen stay with a bath worth photographing.

Coming in at #4 is the pick for travelers who came to Noboribetsu mainly to soak. Hotel Mahoroba is a large onsen hotel in the heart of the hot-spring town, and its calling card is the range of baths — indoor pools, open-air rotenburo, and several different spring waters from milky sulphur to clear, all under one roof. For anyone who wants to try bath after bath in a single trip, this is the place: the variety category scores a remarkable 9.5. Being a big hotel, it has the extras to match — a souvenir shop, a massage room, a games room, and a buffet stacked with Hokkaido seafood and beef. It sits central in the onsen district, a 650 m, roughly 8-minute walk from Jigokudani (Hell Valley). Rooms start around $103 a night and the real-guest score lands at 9.0.

We close the Noboribetsu list with the town's onsen legend — Dai-ichi Takimotokan, the best-known ryokan in the best onsen town in Hokkaido. The draw is the bath complex: dozens of pools covering all five spring types Noboribetsu produces, from sulfur and iron to aluminum and saltwater, in a building so large that exploring it eats up an hour. The onsen category alone scores 9.7. Location is the other reason it stands apart — the ryokan sits directly beside Jigokudani, the valley that feeds the whole town its mineral water, so you can walk to the steaming vents and the boiling mud of Oyunuma without a car. Rooms run from classic tatami up to Jigokudani-view suites, with course-by-course kaiseki dinners. Rates start near $120 a night — the highest on this list — and real guest scores top out at 9.4. We recommend it honestly for couples and families who want their Noboribetsu onsen trip to be the best it can be.
