TRUNK(HOTEL) SAPPORO: Opening Date, Rooms, What to Know
107 rooms, a Michelin sushi counter, live music — and none of it is the actual reason to book. The reason is a 40-meter waterway on the 18th floor that TRUNK has never built before.
TRUNK(HOTEL) SAPPORO will have 107 rooms, a Michelin-recognized sushi counter, a chapel, a private cinema, and a live-music lounge when it opens September 17, 2027. None of that is the actual reason to book it. The reason is on the 18th floor: a 40-meter waterway that TRUNK has never built anything like before, in a spa concept the brand didn't previously have.
This is TRUNK's first property outside Tokyo — its fourth hotel overall, and by room count its largest — occupying floors 10 through 18 of the Sapporo Daibiru building in the city's central Odori district. The move outside Tokyo is itself the headline for a brand that built its identity there; everything about the property reads like a deliberate answer to the question of what TRUNK looks like somewhere else.
That answer is called "Mid-Century Folklore," designed by GENERAL DESIGN CO. with TRUNK Atelier. It isn't retro reproduction — it's mid-century restraint filtered through Hokkaido's own material culture: wood-centric textures, traditional handiwork, and finishes meant to keep a guest aware of the region's forests and climate despite being eighteen floors above a city center. The 89 standard rooms and 18 suites are the vehicle for that idea, not really the point of it.
The point is TRUNK(BATH HOUSE), the brand's first dedicated spa, built around an immersive "water utopia" rather than a conventional pool or a single public bath. Guests move through ten distinct bathing zones along the waterway, each engineered around a different combination of lighting, sound, and temperature — swimwear-friendly throughout, closer to a social urban bathhouse than a gender-segregated onsen.
None of that is the actual reason to book it. The reason is a 40-meter waterway TRUNK has never built anything like before.
The register shifts zone to zone on purpose — a rain-drenched jungle passage in one stretch, disco balls suspended over water in another, high-temperature sauna terracing lit from beneath each step, and quieter leather-lounger rooms built for the pause between the more theatrical spaces. Open-air baths complete the loop. It's designed as a sequence of contrasting conditions to move through, not a single wellness amenity to sit in.
Everything else in the building is genuinely strong and still plays a supporting role. The hotel's 10th-floor counter will be Sushi Saito's first Sapporo location, pairing the Michelin-recognized restaurant's Edo-mae technique with Hokkaido's own seafood, alongside all-day dining and a lounge bar with live music. A chapel opens straight onto forest for ceremonies, and a private studio handles cinema and karaoke on request.
Nightly rates are projected between ¥60,000 and ¥600,000 — roughly $375 to $3,755 — which places TRUNK(HOTEL) SAPPORO firmly in design-led luxury rather than mass boutique territory. A relatively small key count, a headline spa, and destination-level dining all pointing the same direction suggest TRUNK is building a cultural hub for the city rather than simply a place to sleep between days on the slopes.
TRUNK hasn't yet released the waterway's depth or temperature range, specific sauna capacities, whether bathhouse access is included for every room category, or a treatment menu — the kind of operational detail that typically surfaces closer to when reservations actually open. What's already clear is the bet underneath all of it: that a bathhouse, done seriously enough, can be the headline attraction of a hotel the way a view or a restaurant usually is.
