The Overview

Melbourne-based skier and snowboarder with 50+ resorts across 5 continents. Specialises in Australian resorts and international resort comparisons.
Aomori Spring operates on the northern slopes of Mount Iwaki in Aomori Prefecture, rising from 397 metres at the base to 922 metres at the gondola summit. The resort claims 525 metres of vertical drop across 14 runs covering 50 hectares, with a terrain split of 50 per cent beginner, 30 per cent intermediate and 20 per cent advanced. Annual snowfall averages 8 metres, delivered as dry powder from northwesterly systems tracking across the Sea of Japan. The resort is part of the Indy Pass network, offering passholders two days of skiing plus discounted third-day access.
The longest marked run stretches 3.4 kilometres from gondola summit to base, known as Main Line, a green-rated cruiser through mature beech forest. Advanced terrain concentrates on the upper mountain, with pitches approaching 30 degrees and widespread tree skiing in the beech zones below the ridgeline. The resort markets its 22-foot superpipe as the largest in Japan, paired with an all-levels terrain park that operates day and night under floodlights. Off-piste exploration requires guided tours, which access lift-served sidecountry and backcountry ascents towards Mount Iwaki's 1,625-metre summit.
Rockwood Hotel & Spa provides the only slopeside accommodation, a ski-in ski-out property with western-style rooms and indoor-outdoor onsen baths overlooking the Tsugaru Plain. Daily lift ticket sales cap at 1,200 to manage crowds, though weekday visits rarely see queues. The resort attracts a predominantly domestic clientele, with minimal international traffic outside Indy Pass holders. Dining spans hotel buffets, a mountaintop café, a ramen house at the chairlift base, and après options including karaoke facilities.
Aomori Spring suits intermediate skiers seeking uncrowded powder, freestyle riders drawn to the park infrastructure, and families requiring mellow green terrain. The 2025-2026 season runs 13 December to 5 April. Former names include Naqua Shirakami Ski Resort and Ajigasawa Ski Resort, reflecting ownership changes since the original 1960s development under Seibu Group. Night skiing operates on selected trails, though availability varies by season and conditions.

When to visit Aomori Spring
The 2025-2026 season operates from 13 December 2025 through 5 April 2026, spanning approximately 16 weeks. Historical season lengths vary between mid-December openings and late March or early April closures, depending on snowpack depth and spring weather patterns. The resort formerly extended operations into early May during high-snow years, though recent seasons have concluded by early April. Season pass validity runs 14 December 2025 to 5 April 2026, offering a slightly condensed window compared to daily ticket availability.
Aomori City, 54 kilometres northeast at sea level, receives 8 metres of annual snowfall, establishing the prefecture's reputation as Japan's snowiest urban centre. The resort sits at higher elevation on Mount Iwaki's northern exposure, benefiting from consistent northwesterly storm tracks off the Sea of Japan. Snowmaking infrastructure remains minimal, relying instead on natural accumulation to build and maintain base depths. Eight metres of annual average snowfall translates to approximately 800 centimetres, though the resort does not publish season-total or weekly snowfall data publicly.
January and February deliver peak powder conditions, with frequent storm cycles and coldest temperatures preserving snow quality through extended periods. Early season December skiing depends on sufficient base-building storms, whilst March offers longer daylight and occasional spring corn cycles. The resort's northern latitude and coastal proximity mean temperatures remain colder than southern Honshu resorts, extending powder preservation into late season. Weekdays see negligible crowds, particularly outside Japanese national holidays and school breaks.
Night skiing operates on selected trails under floodlighting, though the resort does not maintain a fixed night-skiing schedule across the full season. No major on-mountain festivals or competitive events appear on the published calendar. The terrain park and superpipe remain open day and night when conditions permit. Guided backcountry tours require advance booking and operate subject to weather and avalanche conditions, with prices starting from 13,000 yen per person for group outings.

Getting there
Getting to Aomori Spring, and where to stay
Aomori Spring occupies the northern slopes of Mount Iwaki in Ajigasawa, a coastal town in Nishitsugaru District, western Aomori Prefecture. Mount Iwaki rises to 1,625 metres, making it Aomori's highest peak and a focal point of Tsugaru Quasi-National Park. The resort base sits at 397 metres elevation, approximately 14 kilometres inland from the Sea of Japan coastline. The surrounding landscape consists of beech forest transitioning to volcanic ridges, with views extending across the Tsugaru Plain to Hokkaido on clear days.
Ajigasawa town centre lies 14 kilometres northwest of the resort, with a population of approximately 8,250 residents. Hirosaki, a city of 164,000 known for cherry blossoms and Hirosaki Castle, sits 40 kilometres southeast. Aomori City, the prefectural capital with 280,000 residents, lies 54 kilometres northeast. The region formed part of the Tsugaru clan's Hirosaki Domain during the Edo period, with Ajigasawa functioning as a kitamaebune trading port. Mount Iwaki is locally known as Tsugaru Fuji due to its symmetrical volcanic cone resembling Mount Fuji.
Road access follows Route 101 along the coast from Ajigasawa, then Route 31 ascending inland to the resort. From Hirosaki, the drive takes approximately 40 minutes via Routes 7, 41, and 31. Aomori City requires 80 minutes by car via the Aomori Airport Toll Road and coastal Route 101. The nearest train station is JR Ajigasawa Station on the Gonō Line, situated 20 minutes by taxi from the resort base. No public bus service currently connects the station to the mountain.
Aomori Airport sits approximately 50 kilometres east, offering domestic flights to Tokyo Haneda (75 minutes), Osaka Itami, Nagoya Chubu, and Sapporo Chitose. The airport also handles international services from Seoul Incheon. Rockwood Hotel operates scheduled shuttle transfers from the airport, requiring advance reservation. The Tohoku Shinkansen reaches Shin-Aomori Station in 3 hours 10 minutes from Tokyo, followed by an 80-minute drive or hotel transfer. From Shin-Aomori, the JR Gonō Line local train reaches Ajigasawa in approximately 80 minutes, connecting to taxi or pre-arranged pickup.

Spain Moves to Ban Smoking at Ski Resorts Under New Tobacco Law
Spain's government has approved a draft tobacco law that would ban smoking across a wide range of outdoor spaces, including sports venues - a category Spanish winter sports media expect to cover ski resorts, potentially extending to slopes and lifts themselves. The rules would also apply to e-cigarettes and vaping devices, even nicotine-free ones. The bill still has to clear the Spanish parliament before any ban, signage, or fines can take effect.

South Tyrol Approves New 16-Person Ciampinoi Gondola in Val Gardena
South Tyrol has approved a full rebuild of the Ciampinoi cable car in Selva di Val Gardena, replacing the current 12-person gondola with a 16-person cabin and a new mountain-station restaurant. Capacity is capped at 3,200 people an hour rather than the 3,600 the operator wanted, and 250,000 euros must go toward compensatory measures. No construction or opening date has been set, though the upgrade is partly aimed at clearing bottlenecks before the 2031 Alpine Ski World Championships.

La Thuile's New Cable Car Replaces Two Ageing Chairlifts
La Thuile is spending 38.7 million US dollars on a new 10-person cable car linking Les Suches to Chaz Dura, replacing the La Combe and Chaz Dura chairlifts after nearly forty years of service. Built by Leitner, the new cable car runs 1,950 metres to a top station at 2,576 metres, carrying up to 3,000 people an hour with a six-minute ride. It also improves the connection to La Rosiere in France via the Petit-Saint-Bernard Pass, and is on track to open for the 2026/27 season.

The Remarkables Adds Scarpa Bowl to Its Inbounds Terrain
The Remarkables is adding new inbounds terrain for winter, bringing the Scarpa Bowl - known locally as the Toilet Bowl - into its lift-accessed network after years as backcountry-only ground. The roughly 500 metre run is reached by bootpacking from the top of the Sugar Bowl chairlift, with a shuttle picking skiers up from the road at the bottom. It's a smaller, faster addition than the resort's planned Doolans expansion, though the new terrain hasn't opened yet due to a lack of snow this season.

Ski Portillo Cut Off After Storm Dumps More Than 4.5 Metres of Snow
Ski Portillo remains isolated after an extended storm buried the Chilean resort under more than 4.5 metres of snow, with both ground and air access suspended since Tuesday while crews monitor avalanche hazards and worsening weather. Resort officials say further snowfall is expected in the coming days and haven't set a timeline for reopening the mountain road. Once access resumes, the scale of the snowpack could set up a strong season at one of the Southern Hemisphere's most historic ski resorts.

Lift system
The resort operates five lifts: one six-person gondola, two detachable quad chairlifts with weather hoods, and two fixed-grip double chairlifts. The gondola handles the majority of uphill traffic, ascending nearly the full 525-metre vertical from base elevation to the 921-metre ridgeline. Both hooded quad chairs service mid-mountain zones and provide wind-protected uplift during storms. The Diamond Pair double chair accesses tree skiing terrain, whilst the Aspen double lift primarily serves terrain park and pipe sessions.
The gondola, branded Naqua Shirakami Gondola during the resort's previous ownership era, remains the primary uphill artery. Quad 1 and Quad 2 sit lower on the mountain, creating a lift network that allows multiple lap options without mandatory gondola queues. The gondola cabin design includes large windows for views across the Tsugaru Plain and towards Hokkaido on clear days. Lift infrastructure dates from multiple installation periods, with the gondola and hooded quads representing more recent investment compared to the fixed-grip double chairs.
Uphill flow begins at the gondola base near Rockwood Hotel or at the secondary Quad 1 base station, which houses a visitor centre and automated ticketing kiosk. Most riders ascend via gondola to access the ridge, then lap via the quads for tree runs or return to the summit for groomed cruisers. The lift system handles storm conditions effectively, with hooded quad chairs continuing operation when wind forces the gondola offline. Bottlenecks rarely form outside peak holiday periods, given the daily ticket cap policy.
Recent infrastructure updates include the automated ticketing system at Quad 1 base and scheduled lift maintenance programmes. No major lift replacements have been announced for upcoming seasons. Lift tickets use paper format requiring presentation to operators at each embarkation. The resort does not report specific uphill capacity figures, though the gondola and two detachable quads provide adequate transport for the current skier volume under the 1,200-ticket daily limit.
