Lotte Arai drops a full 1,100 metres across 212 hectares, from a 329-metre base to a 1,429-metre summit, which makes it far bigger than its 14 runs suggest. The split is 36% beginner, 36% intermediate, 20% advanced and 8% expert, a more balanced spread than most Japanese resorts. Two gondolas, two quad chairs and two double chairs move skiers around a mountain in the Myoko region of Niigata Prefecture. Groomed runs are only part of the story, because the larger prize at Arai is the lift-accessed off-piste terrain beyond the piste markers, which draws experienced powder skiers.

On the groomed side, the Myoko Long Run stretches about 5.2 kilometres and Village Road keeps beginners comfortable, while Exciter and Mamushi Gaeshi give advanced skiers real pitch. Off-piste, Zendana Bowl and Big Bowl are broad open faces, with steeper numbered lines such as the KG gates for confident skiers. Tree skiing ranges from open glades to tighter timber, and patrol opens zones after good snowfall. Arai suits strong intermediates through to experts wanting guided-style powder access without leaving the resort boundary. Always check conditions and zone status with patrol first, and carry avalanche gear for anything beyond the gates.

The 2025-2026 season operates from 5 December 2025 to 29 March 2026, spanning 115 days. Lotte Arai typically runs from early December through late March, with some years extending operations into late April or early May depending on snowpack. The Myoko region receives consistent storm cycles from December through March as northwest flow off the Sea of Japan wrings moisture against the first mountain barrier.

Annual snowfall averages between 15 and 22 metres depending on measurement location and seasonal variation, with the resort's position and elevation creating reliable powder accumulation. Base elevation of 329 metres yields denser snow near the gondola, whilst upper elevations above 1,000 metres maintain squeaky, dry conditions through midwinter. The resort offers limited snowmaking, relying primarily on natural accumulation. Base depths regularly exceed three metres during peak winter.

January and early February deliver peak powder conditions with frequent multi-day storm cycles and cold temperatures preserving snow quality. Late December sees strong early-season accumulation, whilst March transitions to spring corn conditions with extended daylight and milder temperatures. Weekdays between mid-January and early February offer optimal powder with minimal crowds, avoiding the holiday rush periods that draw domestic visitors.

The resort operates snow tubing, a Kids' Garden play area and snow rafting activities throughout winter. First tracks programmes allow early gondola access for dedicated powder seekers. Spring events include terrain park setup in the Zendana area from late season onwards. The resort transitions to green season operations from May through November, featuring the 1,501-metre zipline tour and Tree Adventure aerial course.
