The new luxury resort in Hokkaido promises panoramic views from every room, an infinity onsen framing an iconic volcano and a rooftop designed for cosmic contemplation
A new chapter in Niseko—Japan’s premier powder destination—begins with the arrival of Chalet Ivy Weiss. Opening winter 2025, the luxury resort reimagines what a mountain sanctuary can be. Set high in the secluded Hanazono Weiss district at 450 metres, the 87-room hideaway trades slopeside bustle for something rarer—a deep connection to untouched alpine wilderness.
From the volcano-framing infinity onsen to a lounge where the stars feel within reach, every space is designed for reflection and renewal. Chalet Ivy Weiss is a year-round expression of quiet, contemporary luxury in Hokkaido.

Beyond the developed centres of Hirafu lies the Hanazono Weiss district, where Chalet Ivy Weiss claims its elevated position at 450 metres. This deliberate seclusion transforms geography into luxury—a mountain road ascends past the crowds to deliver guests into untouched wilderness. Here, seas of clouds drift within reach, mist blankets the forest at dawn and the only soundtrack is falling snow and whispering trees.
Every room has a premium view

In a gesture of architectural commitment, Chalet Ivy Weiss eliminates the room lottery entirely. Every single one of its 87 guestrooms offers breathtaking scenery—whether majestic Mount Yotei, the rugged Niseko range (including Annupuri and Iwaonupuri) or serene pastoral meadows where cattle graze. This democratisation of the premium view ensures every guest experiences the resort’s most valuable asset: its panorama.

Fed by the property’s own sodium-bicarbonate chloride spring, the infinity onsen serves as the resort’s visual and experiential centrepiece. The infinity edge frames Mount Yotei like a living artwork, creating a seamless transition between healing mineral water and the iconic volcanic peak in Hokkaido. Guests soak away muscle fatigue while moonlight illuminates the alpine landscape surrounding them.
A transcendent experience with the stars

Chalet Ivy Weiss positions a non-skiing, non-dining experience as the pinnacle of any visit. At its rooftop space, guests encounter what the luxury resort describes as the stay’s “ultimate climax”—the night sky delivers countless starlit drops. In a region celebrated for kinetic winter sports energy, this emphasis on cosmic contemplation offers sophisticated tranquillity.

Tailored treatments utilise natural and locally sourced ingredients, while the seventh-floor fitness centre transforms routine exercise into inspiration through expansive windows revealing the Niseko range. Body and spirit refresh simultaneously against an alpine backdrop.
