Kumanoyu is where powder hunters go to disappear - literally one of Shiga Kogen's most remote corners with jade-green onsen water and the kind of steep sidecountry that locals guard like state secrets. While everyone's fighting for fresh tracks at the famous resorts, you'll be skiing untouched bowls at 1,960m and soaking in what might be Japan's most beautiful mountain onsen.
Terrain
12 marked runs across 260m of vertical, but that's missing the point - this is a gateway to Shiga Kogen's best backcountry. Five short black runs and decent intermediate terrain on-piste, but the real action is in the sidecountry tree runs and off-piste bowls that you'll have mostly to yourself. At 1,700m base elevation, the snow stays deep and dry even when lower resorts are struggling.

Vibe Check
This is proper Japanese local territory - minimal English, slow old-school lifts, and the kind of place where you're more likely to see ski tourers than Instagram photographers. Weekdays you'll genuinely have runs to yourself; even weekends feel empty compared to the Shiga Kogen circus up north. It's quiet, respectful, and focused on skiing rather than the scene.
"Had the place nearly to ourselves on a Sunday! Very quiet on weekdays which made for great skiing!"

Timing
December through February for the deepest powder - the 1,700m base elevation holds snow better than most Nagano resorts. Avoid the resort entirely during low snow periods as the limited terrain becomes even more restrictive.

Pro Tips
Off the Mountain
Overpriced base lodge with basic Japanese fare - most skiers eat before arriving or pack lunch.
None - this is a day skiing destination with early closing times
Same ski pass, different terrain
Kumanoyu is excellent for powder hunters seeking solitude and sidecountry access - it's one of Shiga Kogen's most remote corners with untouched bowls and tree runs you'll have mostly to yourself. The 12 marked runs across 260m vertical are just the gateway to serious lift-accessed backcountry terrain at 1,700m base elevation where snow stays deep and dry. What makes it special is the combination of genuine solitude (even weekends feel empty) and those legendary jade-green onsen baths overlooking the mountains.
Learn moreNo - Kumanoyu is not beginner-friendly despite being part of Shiga Kogen. This corner focuses on steep pitches and sidecountry access rather than groomed learning terrain, and the extremely slow lifts that staff won't help with make the learning experience frustrating. If you're new to skiing, choose one of the more accessible Shiga Kogen areas instead.
Learn moreTake the Shinkansen from Tokyo to Nagano (about 1.5 hours), then catch a local bus to Shiga Kogen that requires advance reservation - total journey is 3-4 hours. Note that English support is minimal here, so having your reservation details ready in Japanese will make the trip smoother.
Learn moreDecember through February delivers the deepest powder at Kumanoyu - the 1,700m base elevation holds snow better than most Nagano resorts. Avoid visiting during low snow periods entirely, as the already limited terrain becomes even more restrictive and not worth the journey.
Yes - and it's widely considered the best hot springs in all of Shiga Kogen. The rotenburo (outdoor) and indoor baths feature stunning jade-green water in cypress tubs with mountain views, making them worth the journey alone even if the skiing disappoints.
English support is minimal - this is proper Japanese local territory where you'll struggle with basic resort navigation if your Japanese is limited. The staff can't or won't communicate in English, and signage assumes Japanese literacy, so brush up on essential phrases before visiting.
Rarely crowded - you'll genuinely have runs to yourself on weekdays, and even Sundays feel empty compared to other Shiga Kogen areas. Crowds simply aren't an issue here, which is exactly why powder hunters and solitude seekers make the journey to this remote corner.
The onsen - rotenburo baths with jade-green water overlooking the mountains, widely considered the best hot springs in all of Shiga Kogen and worth the journey alone. Combined with untouched sidecountry access and genuine solitude, it's a rare find for skiers who prioritize powder and peace over resort amenities.
The staff won't slow the lifts even when people fall loading, so practice your chairlift skills beforehand. Skip the severely overpriced base lodge food and pack your own snacks, and always check if both lifts are running before making the journey since one lift down significantly limits your terrain options. Don't expect the Shiga Kogen pass to provide value here - you're essentially forced into an expensive multi-resort ticket for such a small area.
Learn moreYes - sidecountry tree runs and off-piste zones are accessible from the lifts, and this is really the main attraction beyond the onsen. You'll need some navigation skills to find the best lines, but the lift-accessed terrain opens up serious off-piste options that you'll have mostly to yourself.
