Sign InFrequently Asked Questions
How do I get to Marunuma Kogen from Tokyo?
Drive takes about 2 hours via Kanetsu Expressway (exit Numata IC). By train, JR Joetsu Line to Numata Station (2 hours), then bus (1 hour). Direct buses from Shinjuku run on weekends and holidays.
Is Marunuma good for beginners and families?
Yes. About 40% of courses are beginner-friendly. The terrain park welcomes first-timers. Kids' lessons and play areas are available. Long runs through the forest make it scenic for all levels.
When does Marunuma Kogen open and close?
For 2026-2027 the resort plans to open on 4 December 2026 and run until 5 May 2027. The 2025-2026 season ran from 5 December to 6 May, so skiing through Golden Week is normal here: the ropeway climbs to 2,000 m and the resort has snowmaking. Check the website for current season dates.
How much does a Marunuma Kogen lift ticket cost?
Adult one-day passes are roughly ¥5,500–6,500 in peak season, with cheaper half-day, afternoon, and early/late-season rates. Children, students and seniors get standard discounts, and the resort sells family bundles on weekends. Check the resort site for current pricing.
What else can I do at Marunuma Kogen besides skiing?
Snow tubing, snowshoe walks and a kids' snow-play area run all winter. The base hotel (Marunuma Kogen Pension) has an onsen bath open to day visitors, and there's a small ice-skating rink on weekends in peak season. In summer the same area turns into a gondola sightseeing course up to a 2,000 m observation deck, useful if you want to combine skiing with a non-ski day for kids.
