The Overview
Michael Fulton
Melbourne-based skier and snowboarder with 50+ resorts across 5 continents. Specialises in Australian resorts and international resort comparisons.
Asarigawa Onsen operates across 540 vertical metres between 140 and 680 metres elevation, spreading 8 runs over 35 hectares in the Asarigawa Onsen valley 9 kilometres southeast of Otaru. The resort receives approximately 8 metres of annual snowfall and offers direct views of Ishikari Bay and the Sea of Japan from lift-served slopes. Elementary school children and younger ski free when accompanied by adults, and single-day lift tickets start at 3,200 yen. The base elevation sits below 150 metres, making this one of Hokkaido's lowest ski areas.
Terrain divides into 30 per cent beginner, 40 per cent intermediate, and 30 per cent advanced runs across 8 named courses including a 3,000-metre top-to-bottom descent on the Yellow Course. Tree skiing zones flank the upper mountain near the Purple lift, whilst mogul fields develop naturally on steeper groomed runs. The resort includes a terrain park built by the No-Rickers crew with small, medium, and large jumps plus rails and boxes. Wide intermediate cruisers dominate the mountain's midsection.
The day lodge delivers traditional Japanese ski-jo amenities including cafeteria curry, equipment rental counters, and a tune shop. Snow escalators at the base area transport beginners uphill without requiring lift skills. Free parking sits adjacent to the base facilities, and the compact layout allows boot-to-chair transitions in minutes. Crowds remain light throughout the season, particularly on weekdays when local ski clubs and families populate the slopes.
Ski and onsen combination packages at 4,500 yen grant same-day access to natural hot springs in the Asarigawa Onsen village at the base. Season passes cost 32,000 yen for unlimited access from December through March. The 2025-2026 season runs 5 December to 29 March. Low elevation makes Asarigawa ideal when wind closes higher resorts like Kiroro, Sapporo Teine, or Sapporo Kokusai, and proximity to Sapporo and Otaru suits day-trippers seeking uncrowded powder without international resort pricing.

When to visit Asarigawa Onsen
The 2025-2026 season opens 5 December 2025 and closes 29 March 2026, delivering approximately 16 weeks of operation subject to snow conditions. Lifts typically operate 9:00 to 16:00 on weekdays and 8:30 to 17:30 on weekends and holidays from late December through February. Hours reduce to 9:00 to 16:00 during shoulder periods in early December and late March. Dates may shift based on snowpack development and spring melt rates.
Annual snowfall averages 8 metres across the season with the snowiest period typically occurring in late December when 46 centimetres can fall during a single week. The fourth week of December historically records 6.4 snowy days. Low base elevation at 140 metres means snow quality varies more than higher Hokkaido resorts, though northeast-facing aspects help preserve powder between storms. Snowmaking infrastructure is minimal given Hokkaido's natural snow reliability.
January and February deliver the most consistent conditions with stable cold temperatures and regular storm cycles from the Sea of Japan. Late December through mid-February offers optimal powder timing, whilst March brings spring corn snow and longer daylight. Weekdays see significantly lighter crowds than weekends, with minimal competition for fresh snow in tree zones and ungroomed areas. The resort's low elevation provides refuge during high-wind days that shut down exposed mountaintop lifts at neighbouring resorts.
No major events calendar or festival programming is advertised for the season. The resort caters primarily to local families, school ski programmes, and day-trippers from Sapporo and Otaru rather than destination tourists. Combined ski-and-onsen packages encourage post-skiing relaxation in the adjacent hot spring village. Freestyle lessons with the No-Rickers crew cost 1,000 yen for 90 minutes, representing exceptional value for terrain park instruction.

Getting there
Getting to Asarigawa Onsen, and where to stay
The resort sits in the Asarigawa Onsen valley within Otaru city limits in western Hokkaido's Shiribeshi subprefecture. Base elevation at 140 metres places the mountain just inland from Ishikari Bay on the Sea of Japan coast. The small hot spring village of Asarigawa Onsen clusters at the base with hotels, pensions, and day-use onsen facilities. Summit views at 680 metres span Otaru city, the Ishikari coastline, and the Mashike mountain range across the bay.
Otaru city centre lies 9 kilometres northwest, a 15-minute drive or 20-minute bus journey from JR Otaru Station. Sapporo sits 35 kilometres southeast, approximately 40 minutes by car via the Sasson Expressway or one hour by bus. Otaru developed as Hokkaido's primary port city in the early 20th century and retains historic canal districts, glassworks, and seafood markets. The city population exceeds 107,000 with strong tourism infrastructure supporting visitors to nearby ski areas.
The Sasson Expressway's Asari Interchange sits 5 minutes from the resort base via local roads. Driving time from Sapporo runs 40 minutes in normal conditions using the Douou Expressway to Asari IC. Road access remains straightforward year-round as studless winter tyres handle most conditions on the valley approach. Free parking at the base accommodates day visitors without advance reservation requirements.
New Chitose Airport sits approximately 80 kilometres southeast, a 60-minute drive or 90-minute journey by combining the Rapid Airport train to Otaru with onward bus service. Direct JR Rapid Airport trains connect New Chitose to Otaru-Chikko or Otaru stations in 75 minutes with departures every 15 minutes during daylight hours. Chuo Bus operates regular service from Otaru Station to the Asarigawa Onsen bus stop with 30-minute travel time, followed by a 5-minute walk to lifts. Buses also connect from Sapporo's Nakajima Koen subway station for 820 yen each way.

Thredbo Is 'On the Table' as EVT Reviews Its Whole Business
Thredbo is officially 'on the table.' EVT Limited, owner of Australia's most decorated ski resort, has hired Rothschild & Co to review its entire corporate structure - and confirmed Thredbo isn't off limits, even as it books a stronger year of earnings. The resort's own valuation has nearly halved after a brutal 2026 season, and speculation is already running toward Vail Resorts, Alterra, or a New Zealand operator picking it up. Here's what EVT actually said, and who could buy it.

Ski-E-O! Is the Ski Resort Tycoon Game We Didn't Know We Needed
I'm not a gamer. I'm a skier and snowboarder who happens to have a laptop. So when a ski resort management game called Ski-E-O! landed on Steam, I wasn't expecting to lose an afternoon to it - but here we are. Real mountain terrain, a full weather system, storms that roll in and wreck your snow base, avalanche danger, and enough depth to make RollerCoaster Tycoon feel simple by comparison. Early access lands in November. Here's what a few hours in the free demo actually looks like.

Sugar Bowl, California, Rebuilds Its Historic Village Gondola
The rumours are true: Sugar Bowl is tearing out its Emerald gondola, in place since 1983, and replacing it with a new 8-person Doppelmayr system - nearly doubling uphill capacity to 1,800 people an hour. It's the fourth generation of a gondola line that dates back to 1953, when Sugar Bowl became the first resort on the West Coast to run one at all, and it's just one piece of a $100 million overhaul touching lodges, parking and snowmaking. Here's what's changing, and what's staying the same.

Two Confirmed Dead as Search Continues After Swiss Alps Fire
The death toll from Thursday night's fire at Restaurant Beverin in Thusis, Switzerland, has begun to firm up. One Swiss outlet, citing Graubünden Cantonal Police, reports that two of the five people initially reported missing have now been confirmed dead, leaving three unaccounted for. The building's collapsed stairwell and structural instability have slowed recovery efforts throughout. Here's what's changed since the fire broke out, and what's still unconfirmed.

Selwyn Snow Resort Closes Early as Rain Ends Its 2026 Season
Selwyn Snow Resort has called an early end to its 2026 season, a day after Victoria's Mount Baw Baw did the same. Rain on Thursday stripped what was left of the snowpack, and the cold nights needed to rebuild it through snowmaking never arrived. It's a rough result for a resort that only just found its footing again after being burned to the ground in the 2019-20 Black Summer bushfires and a multi-year rebuild. Here's how the season fell apart, and where Selwyn's been since the fire.

Mt Baw Baw Becomes First Australian Resort to Close for 2026
Mt Baw Baw is calling time on its 2026 season this Sunday at 5pm, becoming the first Australian resort to close for the year after warm spells and rain wore through its snowpack. Lifts stop, but the resort stays open, entry fees get waived, and there's one last Bollywood Weekend before the lights go out. Fifty-seven days after opening, here's how the season ended and what it means for the rest of Australia's struggling snowpack.

Arosa to Replace 40-Year-Old Hörnli Lifts With New Gondola and Chair
Arosa's Hörnli sector is getting its biggest overhaul in decades. The 1986 gondola and 1994 chairlift linking toward Lenzerheide are both being replaced, with capacity up, tower count down and a new base station lower on the hill. At roughly CHF 67 million, it is the largest single investment Arosa Bergbahnen has ever made - and the target opening has already slipped a year, to December 2028. Here is what is changing, and why the timeline moved.

Sundance Mountain Resort Is Getting a New High-Speed Quad and More Back Mountain Terrain This Winter
Sundance Mountain Resort's back mountain is finally getting a proper lift. The Electric Horseman Express opens for 2026-27, unlocking a new bowl next to Bishop's Bowl and three expert gladed chutes across roughly 105 fresh acres - on top of the Storyteller ridge run that debuted in preview form last season. It's Sundance's biggest expansion since 1985, and it turns a three-lift slog into a single six-minute ride to Bearclaw Summit.
