Noboribetsu Sekisuitei — the mountain ryokan where the rotenburo sunset view makes you forget everything
Have you ever soaked in an open-air hot spring on a mountain summit while an entire valley spread out in front of you, the sun painting the peaks orange and pink? That is exactly what Noboribetsu Sekisuitei offers. This ryokan earns 8.9 from 1,547 reviews on Booking, and its rate of ¥20,000 per night for two guests already includes a premium Hokkaido kaiseki dinner and breakfast — a combination that guests consistently describe as better value than expected.
Noboribetsu Sekisuitei is located at 173-1 Noboribetsu Onsen-cho in Noboribetsu City, Hokkaido — just a 3-minute walk from the Bus Terminal. Getting here means taking the JR Hokuto from Sapporo for around 65 minutes, then connecting to the Donan Bus for about 13 minutes up into the onsen village. What sets Sekisuitei apart from most ryokan in Noboribetsu is its position: this property sits higher than the majority of accommodation in the village. Step through the rotenburo door and the full sweep of the Noboribetsu valley — mountain ridges as far as you can see — opens up in front of you.
"Guests who have been say the same thing: the 16:30–17:30 rotenburo sunset slot is Sekisuitei's legendary moment — there's nothing else quite like it anywhere in Noboribetsu."
The single thing guests talk about most is the open-air rotenburo on the mountain top. It is open 24 hours — soak at 10 pm, or at 5 am if you like — but the timing that comes up in review after review is 16:30–17:30, when the sun sets and turns the mountain range ahead of you a vivid orange-pink. In winter, if snow is falling while you sit in water at 41°C, the cold outside is entirely forgotten. This is the kind of experience that many guests say permanently changed their understanding of what onsen can be.
On the Hokkaido kaiseki dinner — Sekisuitei's evening meal is a multi-course kaiseki using premium Hokkaido seafood, approximately 9 dishes, and it is included in the ¥20,000 rate for two guests along with breakfast. By the standards of kaiseki in Noboribetsu, many guests who have stayed here report this as the lowest price for a ryokan operating at this score level in the area. For anyone who wants a genuine kaiseki experience but finds ¥30,000+ per night out of reach, Sekisuitei is a compelling option.
The guest rooms are traditional tatami with futon bedding — you sleep on the floor, the room carries a faint wood scent, and the atmosphere is authentically Japanese in a way that contemporary-style onsen hotels rarely capture. Guests who have come for that feeling tend to love it. Those accustomed to high spring mattresses may need the first night to adjust. Multiple guest reviews note that the in-room bathroom is on the older side, though well maintained — the property has a renovation planned for 2027.
Regarding Wi-Fi — a recurring thread in reviews mentions that the signal can be slow in some upper-floor rooms. This is a limitation found in mountain ryokan elsewhere too, and worth knowing. If you need fast, reliable internet for remote work, this is not the right base. But if the plan is to fully switch off for a night or two, Sekisuitei is a near-perfect setting for exactly that.
The 3-minute uphill walk from the Bus Terminal is straightforward in summer, but in winter when snow falls heavily the path can become slippery. Elderly guests or anyone with mobility considerations should enquire with the property about the path conditions and any available assistance. For most guests in reasonable health, the distance is trivial — but it is worth knowing before you arrive with large luggage in icy conditions.
To put it plainly: Noboribetsu Sekisuitei is made for travellers who want a genuine traditional Japanese mountain ryokan experience — open-air onsen with sunset valley views, Hokkaido kaiseki, and an atmosphere that city hotels simply cannot replicate. A score of 8.9 from 1,547 reviews confirms that most guests receive what they came for. And for many, that rotenburo sunset moment turns into the single lasting memory of an entire Hokkaido trip.
