NISEKO, Japan, October 1, 2026: C9 Hotelworks has released its Niseko Tourism, Hotel and Property Market Review 2026, combining its own market research with hotel performance data from STR CoStar. The review finds Japan’s leading ski resort entering a period of rapid supply growth, with its investment case increasingly tied to trading beyond winter.
“Niseko has built one of Asia’s strongest winter markets, but 792 new hotel keys can’t be filled in four months,”. “Our review shows demand deepening through longer stays and new North American access. The next chapter of Niseko’s story will be written in the shoulder seasons.”
Bill Barnett, Managing Director of C9 Hotelworks
Winter visitor arrivals across Kutchan, Niseko and Rankoshi rose 8.4% to 2.14 million between November 2025 and March 2026. Stays lengthened, with 24.5% of international overnight guests staying eight nights or more, up from 21.7% the previous winter. International guest nights increased 32.9%.
The United States is now Niseko’s largest international source market by overnight guests at 40,504, up 15.2%. Access improves in December, when United Airlines from San Francisco and Air Canada from Vancouver each begin three weekly flights to New Chitose Airport.
STR CoStar data for the Niseko market confirms winter remains the engine. February 2026 occupancy reached 84.8%, up 6.0 percentage points, at an ADR of JPY 156,773 (USD 988), while March RevPAR grew 24%. Summer is where the shift is showing. ADR rose 10.6% in June and 15% in July to JPY 40,209, and July occupancy improved 4.1 points to 41.1%, lifting RevPAR 27.7%.
“July delivered year-on-year growth in both occupancy and rate, and ADR growth was the strongest of the past twelve months,”. “The opportunity now sits in April to June, when occupancy remains between 19% and 26%, well below winter levels.”

That gap matters because supply is rising fast. Moxy Niseko Village (310 keys) and Hotel101 Niseko (482 keys) take inventory from 1,727 keys to 2,519 by end-2026, a 46% increase.
Primary residential supply rose 27.6% to approximately 2,500 units, the highest level in the 2018 to 2026 period, with Fairmont, Hoshinoya, The Chedi and Aman in the pipeline through 2030.
