Hotel 101 Niseko Opens December 2026: 482 Rooms, Two Indoor Pools, Kids' Play Area

482 rooms, opening in December 2026: the biggest hotel ever built in Hirafu is almost ready. Hotel 101 Niseko is run by Philippine group DoubleDragon through its Hotel101 Global brand, and when it opens it will be Hirafu's largest hotel and Hotel101's first property in Japan (Daily Tribune). The specific opening day is still only "December" at the time of writing. The site sits in Niseko Hirafu 4-jo 1-chome, right next to Mercure Niseko Resort, which opens three weeks earlier (Powderlife). If you're still choosing where to stay, read Where to stay in Niseko first; the Hirafu sub-areas affect your trip more than the map suggests.

What kind of hotel is Hotel 101 Niseko?

The operator is DoubleDragon, a Philippine property group, and its overseas brand Hotel101 Global. After Hotel101 Madrid (680 rooms, opened March 2026), Niseko is the chain's second overseas property (Insider PH). The Hotel101 formula is simple: a standardised "Happy Room" that looks the same in every country, in the mid price band. It is not a one-of-a-kind luxury resort, and it is not a traditional ryokan; it is a predictable mid-market room, scaled up and repeated.

The announced facilities cover two indoor pools, a mineral hot bath, a sauna, a fitness room, an all-day dining restaurant, a children's play area, in-house ski rental, and ski lockers (Daily Tribune). As of July 2026 the facade was complete and interior fit-out was underway (Insider PH). Freshly opened hotels usually need two to three weeks before breakfast service and housekeeping settle in, so if this is your first Niseko trip, don't stack opening week against the New Year rush.

How big is 482 rooms, in Hirafu terms?

Lining it up against the other Hirafu hotels makes the scale clear.

That gap changes how the lobby, breakfast room and lifts feel. In a 482-room hotel at peak season, budget 15 to 20 minutes from your room to the breakfast table; a small hotel where you walk down and sit is a different experience.

What's the difference from Mercure Niseko Resort?

Two new hotels right next to each other at Niseko Hirafu 4-jo 1-chome, opening three weeks apart: the names get mixed up easily. The published differences, side by side.

If you want a hotel you can play inside (pools, kids' area), Hotel 101 is the natural fit. If you want a familiar global brand's breakfast and service standards, Mercure is the honest answer. Peak-week rates swing hard, so pick your window in When is the best time to visit Niseko? first, then plug dates into each hotel's booking page.

Before you book for 2026-27

As of 2 November 2026, the exact opening day for Hotel 101 Niseko, the direct booking page, and peak-week pricing (New Year, Lunar New Year) have not been independently confirmed. Rather than guess, check these four points on Hotel101 Global's official page or the OTAs listing it, before you commit.

• Opening day: announced only as "December". If you want to be in the first guest intake, wait for the firm date before booking
• Rates: peak (New Year, Lunar New Year) vs regular, max occupancy per room, and whether breakfast is included
• Shuttle: service to Hirafu and Hanazono is planned, but the timetable and start date are still to be published
• In-house ski rental: catalogue and booking method, and whether it undercuts off-site rental shops

Hirafu's resorts open on 28 November, so most December guests plan their dates around the opening week. The season start summary is in the 2026-27 opening and lift pass guide.

A 450-unit condo-hotel follows in September 2027

Next to the main building, a 450-unit condo-style phase is tracking a September 2027 completion (Powderlife). The 2026-27 season will overlap with that construction, so if quiet matters, ask the hotel for a room on the side away from the works.

Who it's for, and who it's not for

Good fit: families and groups who want pools and a kids' area inside the hotel, with ski rental one lift away in the same building. 482 rooms also makes it easier to book multiple rooms side by side at peak season.

Not a fit: people who want a quiet morning and a slow checkout, since big hotels get busy at peak times. Skiers who prize ski-in access should look at Ki Niseko (~100 m from the Grand Hirafu gondola) instead. If an unknown brand's first Niseko property feels risky for a big trip, waiting one season to 2027-28 is a reasonable call.
