Gransnow Okuibuki will open on Friday, 13 November 2026 for the 2026-2027 winter season. The season is planned to run until Sunday, 11 April 2027, about 150 days. Last season it opened on 14 November.
The resort makes its own snow, which is why it can open this early. It calls 13 November its earliest opening ever.
Gransnow Okuibuki is easiest to reach from the Kansai cities, not Tokyo. Direct ski buses run from Osaka, Kyoto, and Nagoya.
Most resorts near Tokyo announce their dates between September and November. We track every confirmed 2026-2027 date, and explain how season timing works, in one place: When Do Honshu Ski Resorts Open?
