Eighteen meters of annual snowfall. Ten sanctioned freeride zones. Two and a half hours from Tokyo. Arai delivers Hokkaido-level powder without the Hokkaido flight, and 84% of the mountain is designated off-piste terrain - basically sanctioned backcountry without the avalanche course requirement.

Terrain
The real draw is the 84% ungroomed terrain spread across 10 designated freeride zones - basically sanctioned backcountry without the avalanche course requirement. Marked runs are fine but forgettable; the magic happens in the trees and open bowls where fresh tracks linger for days after storms. The 951m vertical gives you proper top-to-bottom descents, though the lower mountain can get heavy when it's warm.
Indoor and outdoor baths, mountain views, connected to resort
Vibe Check
This is a destination resort where Tokyo powder hunters come to get serious - expect quiet weekdays with legitimate terrain to yourself, then weekend invasions of skilled skiers who know exactly what they're here for. The base is all modern resort efficiency rather than village charm, but nobody cares when you're floating through untouched trees at 10am on a Tuesday.
"They close all lifts due to the wind except the useless bunny slope to avoid paying refunds. Absolutely unethical."

Real Reviews
Timing
Mid-January through February for peak powder conditions when the 18-meter annual snowfall creates ideal freeride terrain. Avoid New Year week when domestic crowds surge, and be prepared for wind closures during storm cycles - the mountain's exposure means safety shutdowns are common but temporary.

Pro Tips
Off the Mountain
Limited and overpriced on-mountain options that most reviewers recommend avoiding. The main lodge has typical resort fare at premium prices - better to eat beforehand or pack lunch.
Minimal - this is a destination resort that focuses on skiing rather than après culture. The resort winds down early with limited evening entertainment options.
Same ski pass, different terrain
Arai delivers exceptional skiing with 18 meters of annual snowfall and 84% of the mountain designated as ungroomed freeride terrain - basically sanctioned backcountry without needing guides or avalanche courses. The 951m vertical drop provides proper top-to-bottom descents through 10 designated freeride zones that hold powder for days after storms. It's Hokkaido-level powder just 2.5 hours from Tokyo, making it a serious destination for intermediate-plus skiers ready to explore beyond groomed runs.
Learn moreNot particularly - while 36% of the terrain is rated beginner, Arai's real appeal is the 84% ungroomed freeride zones that require intermediate-plus skills to enjoy safely. The groomed runs are described as "fine but forgettable," and this resort caters primarily to Tokyo powder hunters looking to graduate from groomed terrain to real powder exploration. If you need manicured conditions to feel comfortable, this isn't your mountain.
Learn moreTake the Hokuriku Shinkansen from Tokyo to Joetsu-Myoko Station (about 2 hours), then catch the shuttle bus for the final 30-40 minutes to the resort. Total journey is around 2.5 hours door-to-door, making it one of the most accessible deep powder destinations from Tokyo without flying to Hokkaido.
Learn moreMid-January through February delivers peak powder conditions when the resort's 18-meter annual snowfall creates ideal freeride terrain. Avoid New Year week when domestic crowds surge, and be prepared for wind closures during storm cycles - the mountain's exposure means safety shutdowns are common but temporary. Midweek visits offer the best chance for fresh tracks in the freeride zones without weekend warrior invasions.
Yes - Arai has high-quality indoor and outdoor baths with mountain views, directly connected to the resort facilities. It's perfect for post-ski recovery after spending the day exploring those 10 freeride zones, and multiple reviews specifically praise the onsen as a highlight of the resort experience.
Limited English - basic signs and ticket counters may have English, but don't expect much beyond that. This resort caters primarily to domestic powder seekers rather than international tourists, so brush up on basic Japanese phrases or come prepared with translation apps for dining and services.
Rarely crowded, especially on weekdays when you'll have legitimate terrain to yourself. Weekend mornings get busy at the main gondola as Tokyo-based skiers arrive, but the freeride zones track out slower than you'd expect since most of the mountain is ungroomed terrain. Expect quiet Tuesdays where fresh tracks linger, then weekend invasions of skilled skiers who know exactly what they're here for.
The freeride zone system - 84% of the mountain is ungroomed but patrolled, giving you backcountry thrills with resort safety and no guide fees required. It's basically sanctioned backcountry across 10 designated zones where you can explore trees and open bowls without avalanche courses or expensive guides. You get Hokkaido-level powder just 2.5 hours from Tokyo, making it the closest serious freeride destination to the capital.
Yes - night skiing runs from 16:30 to 20:00, with lifts operating until 21:00. It's a solid option for extending your powder day, though keep in mind the resort generally shuts down early and entertainment options are limited compared to traditional ski towns.
Don't buy multi-day lift tickets without checking weather forecasts - wind closures happen frequently and the resort offers no refunds, even when only the bunny slope remains open. Skip the resort restaurants entirely as the food is overpriced and disappointing; pack your own lunch or eat before arriving. Hit the upper mountain first thing because while freeride zones track out slower than expected, the good snow disappears fast once weekend crowds arrive.
