The Overview
Michael Fulton
Melbourne-based skier and snowboarder with 50+ resorts across 5 continents. Specialises in Australian resorts and international resort comparisons.
Seki Onsen operates across 310 metres of vertical drop from a 900-metre base to a 1,210-metre summit. The area records 14 to 16 metres of annual snowfall and comprises four official runs serviced by two chairlifts, spanning approximately 30 hectares. The ski area sits 30 kilometres from the Sea of Japan on the northeastern slopes of Mount Myoko in Niigata Prefecture, capturing Siberian storm systems that deliver exceptional powder depth. The resort operates from early December through early May, often extending its season well beyond neighbouring areas.
Terrain splits 30 per cent beginner, 40 per cent intermediate and 30 per cent advanced across short but steep runs. The Silver Fan Course remains ungroomed throughout the season, offering the steepest gradients and deepest powder within the Myoko mountain range. Most slopes receive minimal grooming, preserving natural snow conditions for powder skiing. The area allows unrestricted off-piste access through marked sidecountry zones and tree skiing terrain, unusual among Japanese resorts.
Seki Onsen has operated continuously since 1917, making it one of Japan's oldest ski areas. The Inoue family has owned and managed the resort for nearly 50 years, maintaining a low-key operation with no ski patrol presence. A single on-mountain restaurant serves homemade meals, whilst the base village contains minimal facilities. The area attracts international powder skiers seeking untracked terrain and an authentic mountain experience free from modern resort infrastructure.
The resort functions independently with no pass affiliations to neighbouring Myoko resorts. Day tickets cost ¥4,500 for adults, reflecting the minimal lift infrastructure and facilities. Seki suits advanced skiers and snowboarders comfortable navigating steep, ungroomed terrain without patrol oversight. The tiny scale means fresh snow tracks out quickly on popular powder days, typically within hours of opening.

When to visit Seki Onsen
The 2025-2026 season runs from 5 December 2025 through 29 March 2026, though operations frequently extend into early May when snowpack permits. Lifts operate 9:00 AM to 4:30 PM daily. Seki regularly outlasts all other Myoko resorts due to its exceptional snow retention and north-facing aspect. The area celebrated 100 years of skiing operations in 2017.
Annual snowfall averages 14 to 16 metres, among the highest totals in Japan. The resort's position at 1,000 metres elevation where cold Siberian air meets moisture from the Sea of Japan creates ideal powder conditions. Minimal snowmaking exists as natural accumulation proves sufficient throughout winter. Base depths regularly exceed two metres by mid-season, with the upper single chair sometimes buried during storm cycles.
January and February deliver peak powder conditions with frequent storm cycles refreshing terrain every few days. December offers early-season depth whilst March provides longer daylight and spring corn conditions. Late-season skiing continues through April when mogul fields develop on ungroomed slopes. The area's compact size means fresh lines disappear quickly after storms, making timing critical for untracked snow.
Mid-March onwards brings increased activity as other resorts close, with banked slalom competitions and a fireworks festival marking the late season. No night skiing operates. The resort publishes minimal advance scheduling, reflecting its owner-operated flexibility. Powder board test rides and terrain park features appear intermittently depending on conditions and staffing.

Getting there
Getting to Seki Onsen, and where to stay
Seki Onsen sits in Myoko city, Niigata Prefecture, on the northeastern flank of Mount Myoko, a 2,454-metre active stratovolcano. The base village rests at 900 metres elevation in a narrow valley formed by the Myoko mountain range. The Joshinetsu National Park surrounds the area, with the resort positioned 30 kilometres inland from the Sea of Japan coast. Traditional hot spring baths line the village streets, which opened in 1729 as one of Myoko's oldest onsen settlements.
Sekiyama Station on the Myoko Haneuma Line provides the nearest rail access, 10 to 15 minutes by bus or taxi from the resort. Akakura Onsen village, the main accommodation hub for Myoko, lies 12 kilometres south and 30 minutes by road. The town of Myokokogen sits 12 kilometres southeast near the rail station. Tsubame Onsen, another hot spring village, is located 3 kilometres uphill from Seki via Prefecture Road 39.
Road access follows Route 18 to either Myoko Kogen Interchange or Nakago Interchange on the Joshinetsu Expressway, then 15 to 20 kilometres via Prefecture Road 39. Drive times from Nagano city average one hour, whilst Tokyo lies approximately four to five hours south. Winter road conditions require caution as heavy snowfall frequently impacts Route 39. Limited parking at the resort base fills quickly on powder days.
Tokyo's Narita and Haneda airports serve as primary international gateways, approximately 300 kilometres south. Direct shuttle buses operate from both airports to Myoko, taking five to six hours. Niigata Airport sits 160 kilometres northeast, offering limited international flights and two-hour road transfers. Train connections require the Hokuriku Shinkansen to Nagano Station, then the Kita-Shinano Line 45 minutes to Myoko-Kogen Station, followed by a local train to Sekiyama.

FIS Weighs Holding World Championships in Almost Every Winter, Starting 2032
The International Ski and Snowboard Federation is looking at a major shake-up to its title events calendar. From 2032, World Championships could run not just in odd-numbered years but in every non-Olympic winter too, effectively putting a global title event on the calendar almost every season. The FIS Council has approved the concept following a feasibility study, though an accelerated rollout as early as 2028 is also under consideration.

Mount Buller Becomes Latest Australian Resort to Call Time Early on 2026
Mount Buller closes out its 2026 season this Sunday, joining Falls Creek, Hotham and Charlotte Pass in a cluster of closures landing almost simultaneously and roughly a month ahead of schedule. The culprit is stark: Spencers Creek's benchmark snow depth hit 31.2cm on 3 September, just 18% of the 73-year average and an all-time low for this point in the season. Six of Victoria and NSW's best-known resorts will have shut their lifts early within a span of about two and a half weeks.

Tremblant to Add New Timber Summit Ski Sector for 2027/28 Season
Tremblant has confirmed a major expansion of its Quebec ski area, with a new Timber Summit sector adding 62 acres of terrain, eight trails and a high-speed quad chairlift for winter 2027/28. It's part of a CAD 42.5 million investment that also includes a new beginner learning zone at Versant Soleil opening this coming season. The project has grown considerably since it was first announced back in 2020, when it carried a far smaller budget and an opening date that never eventuated.

Mount Hotham to Close for the 2026 Season on Sunday, September 6
We knew when the Bird Bath Pond Skim showed up on Hotham's Instagram that the season was on its way out. It's been a rough one - I only managed two days on snow all year, at Falls Creek - and now Baw Baw, Selwyn and Hotham have all called it, possibly the worst Australian season I've seen in a decade. Hotham's last day of lift operations is Sunday, 6 September, with a Retro Day, Father's Day après and closing sales before the lifts stop turning for good.

Thredbo to Replace Ageing Gunbarrel Quad With New Six-Seat Chairlift for 2028
Thredbo Alpine Resort has confirmed plans to replace its 37-year-old Gunbarrel quad chairlift with a new six-seat Doppelmayr D-Line, targeting winter 2028. The AUD 35 million project will keep travel time roughly the same but lift capacity from 2,800 to 3,000 skiers per hour. It's part of a broader investment push that also includes doubled snowmaking capacity at Friday Flat for 2027, with the ageing Kosciuszko Express now flagged as the resort's next major lift replacement after Gunbarrel.

Understanding the Seki Onsen snow report
See what's happening on the mountain at Seki Onsen right now — snowfall, snow depth, and weather data to help you plan your day in Chubu.
Snow measurements
Our snow reports measure snowfall in centimeters over multiple time windows — last 24 hours, last 7 days, and the season total. Base depth reflects accumulation at the 900m base area, while summit depth captures conditions 310m higher at 1210m, where snow typically stays colder and lingers longer. Imperial conversions are shown alongside for convenience.
Weather conditions
Snow quality tracks closely with temperature and wind. We surface both alongside the snowfall data so you can judge whether conditions at Seki Onsen are holding up or starting to soften.
Data sources
We pull Seki Onsen's conditions from on-the-ground mountain reporting, then layer in forecast data so you get a fuller picture than either source alone. The mountain is served by 18 lifts, including 5 quad chairlifts.
When to check
The biggest swings usually happen right after a storm. Check Seki Onsen's report in the morning for the freshest numbers, and again in the afternoon as conditions evolve.
