Since I know virtually nothing about Japan's many ski areas, for the past year or so I've been gathering info from people's past trips here and on the German forums so I'll have initial guidance when I go there at some point in the future (for the moment, it's armchair travelling). I copied Sbooker's recent itinerary above and asked AI to provide an overview of the various stops:
That list is a real mix, from genuinely small/local hills to pieces of much larger interconnected zones. Here’s the practical breakdown from a skier’s POV:
Larger / more destination-scale (or part of major systems)
Myoko Suginohara
• One of the bigger standalone mountains in Myoko
• Long vertical, more legit destination feel
• Not “mega resort” by Alps standards, but definitely not small
Madarao
• Mid-sized to fairly substantial
• Known for tree skiing and sidecountry
• Bigger than a local hill, smaller than Japan’s giants
Yakebitaiyama (Yakebitaiyama & Okushiga area / Shiga Kogen)
• Large by Japanese standards
• Major groomer infrastructure
• Part of the broader Shiga Kogen complex
Okushiga Kogen
• Not huge alone, but upscale and substantial
• Functions as part of the larger Shiga Kogen ecosystem
• More “serious destination sector” than small ski hill
Medium / mid-tier
Ryuoo Ski Park
• Mid-sized
• Big ropeway, decent vertical
• More substantial than it first appears, though not elite-scale
Yokoteyama
• Individually modest, but high-altitude and linked within Shiga Kogen
• More about niche terrain and snow quality than size
Smaller / feeder / local-feel sectors
Yomase / X-Jam Takaifuji
• Smaller to mid-small
• Fun, often underrated, but not large
Ichinose Diamond
• More of a sector/base area than a major standalone mountain
• Useful in Shiga Kogen network, but individually modest
Kumanoyu (Kumamoyu)
• Smaller, old-school, weather-dependent
• More character than scale
Bottom line
Clearly not small:
• Myoko Suginohara
• Madarao
• Yakebitaiyama / Okushiga (especially within Shiga)
Middle:
• Ryuoo
• Yokoteyama
Smaller:
• Yomase/X-Jam
• Ichinose Diamond
• Kumanoyu
Important context
Japan can be deceptive because many areas function as “pods” within broader regional networks rather than giant single-resort brands like the Alps or North America.
So:
• Shiga Kogen = huge overall, but many individual sectors feel small
• Myoko = regional destination with several separate mountains
• Madarao = stronger standalone than many on your list
If your benchmark is:
• St. Anton / Trois Vallées → most are small
• Typical eastern U.S. independent hill → several are medium to large
• Powder/travel value → some punch above their size dramatically.
