The Overview

Melbourne-based skier and snowboarder with 50+ resorts across 5 continents. Specialises in Australian resorts and international resort comparisons.
Ishiuchi Maruyama operates across 236 hectares with 23 marked runs and a vertical drop of 664 metres, spanning from a base elevation of 256 metres to a 920-metre summit. The resort averages 8 metres of annual snowfall and opened in 1949, making 2024 its 75th anniversary season. The longest single run extends 4,000 metres from summit to base, whilst the resort maintains connectivity to GALA Yuzawa and Yuzawa Kogen through the tri-resort Yuzawa Snow Link pass.
Terrain splits 40 per cent beginner, 40 per cent intermediate, and 20 per cent advanced across the 23 courses, with no designated expert terrain. The Paradise Course delivers wide intermediate cruising with views across the Minamiuonuma Plain and Echigo Sanzan mountains. The resort spreads across three base areas - Central, Hatsukaishi, and North - each offering independent access points. Tree-run zones and ungroomed sections provide powder stashes after storms deliver Uonuma snow.
Independently run lodges and restaurants line the slopes at each base area, preserving traditional Japanese ski culture. The Veranda observation terrace sits mid-mountain and accommodates non-skiers arriving via gondola. Night skiing covers 3,000 metres across 12 illuminated courses, operating daily from late December through February and Friday-Saturday in March. Weekend traffic from Tokyo creates queues at upper lifts, particularly the summit quad.
The Yuzawa Snow Link pass connects 48 combined courses across Ishiuchi Maruyama, GALA Yuzawa, and Yuzawa Kogen from December through March for 3,000 yen over a standard lift ticket. Direct shinkansen access from Tokyo Station to Echigo-Yuzawa takes 80 minutes, positioning the resort for day trips. The terrain suits intermediates seeking variety and beginners building confidence, whilst night operations and terrain park features draw freestyle riders. Proximity to Echigo-Yuzawa onsen town adds post-skiing relaxation options.

When to visit Ishiuchi Maruyama
The 2025-26 season operates from 19 December 2025 through 5 April 2026, spanning approximately 107 days. Night skiing runs daily from 27 December 2025 to 28 February 2026, then Friday-Saturday only through 28 March. The Hatsukaishi and North base areas close 29 March, consolidating operations to the Central zone for the final week. Spring operations extend The Veranda observation terrace through Golden Week from 25 April to 10 May for sightseeing.
The resort averages 8 metres of annual snowfall, with heavy accumulation weeks typically arriving mid-December through February. The Niigata coast's position relative to Siberian weather systems crossing the Sea of Japan delivers consistent powder cycles, with individual storms depositing over 50 centimetres overnight. The base elevation of 256 metres creates marginal temperatures during warm spells. North-facing aspects preserve snow quality longer than south-facing runs. Snowmaking supplements natural coverage on high-traffic zones.
January and February offer peak powder conditions and deepest base depths, though weekend crowds from Tokyo increase during this window. Early December provides quieter slopes with lighter coverage. March delivers spring corn snow and extended daylight, with parking fees waived from 8 March through closing. Late-season operations concentrate on higher-elevation terrain as lower runs thin. December's third week historically records the highest weekly snowfall totals.
The resort programme includes fireworks displays on select evenings and Children's Ski Day on the third Sunday of each month from January to March, offering free lift tickets for elementary-age children. Apres-ski events feature DJ music lounges at the Central base on weekend afternoons. The terrain park undergoes layout renewal in late March ahead of spring sessions. Night skiing offers illuminated halfpipe access and intermediate run options beyond beginner zones.

Getting there
Getting to Ishiuchi Maruyama, and where to stay
Ishiuchi Maruyama sits in Minamiuonuma City, Niigata Prefecture, within the Yuzawa valley of central Honshu's snow country region. The resort base occupies 256 metres elevation surrounded by peaks reaching beyond 1,900 metres, including views toward Mount Iiishi. The Minamiuonuma Plain stretches north from the base, with the Echigo Sanzan mountains framing the eastern skyline. Niigata Prefecture's heavy-snowfall zone benefits from moisture-laden systems off the Sea of Japan.
Echigo-Yuzawa town centre lies 3 kilometres from the resort, a 10-minute free shuttle bus journey from Echigo-Yuzawa Station. Yuzawa gained literary fame as the setting for Yasunari Kawabata's Nobel Prize-winning novel Snow Country. The town offers traditional ryokan accommodation, numerous onsen facilities, and Ponshukan sake museum at the station featuring tastings of over 100 Niigata sake varieties. Ishiuchi Station on the Joetsu Line sits 15 minutes' walk from the Kanko entrance.
The Kan-etsu Expressway provides road access via Shiozawa-Ishiuchi Interchange, located 5 kilometres and approximately 5 minutes' drive from the resort along Route 17. Tokyo's Nerima Interchange sits 120 minutes distant via expressway. Parking costs 1,000 yen on weekends and holidays but operates free on weekdays and from 8 March through season close. Four separate entrance gates - two Central gates, North entrance, and Hatsukaishi entrance - serve different parking zones and terrain areas.
Tokyo Station connects via Joetsu Shinkansen to Echigo-Yuzawa Station in 80 minutes, with free shuttle buses departing the east exit every 10-15 minutes during operating hours. Haneda Airport requires 2 hours by train to Echigo-Yuzawa, whilst Narita Airport extends to 3 hours. Niigata Airport sits 90 minutes away via bus to Niigata Station then 80-minute train to Echigo-Yuzawa. Multi-resort shuttle buses link Ishiuchi Maruyama with GALA Yuzawa, Yuzawa Kogen, and NASPA resorts on circular routes.

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.

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 Ishiuchi Maruyama snow report
Planning a day at Ishiuchi Maruyama? Our snow report combines official mountain data with live weather so you know exactly what conditions look like right now, from the 256m base to the 920m summit.
Snow measurements
Base depth, summit depth, and recent snowfall are the core numbers to watch. At Ishiuchi Maruyama, summit conditions (920m) can differ noticeably from the base, so we break both out separately rather than showing a single average.
Weather conditions
Wind and temperature swings matter as much as fresh snowfall. Cold, calm conditions hold snow quality well, while wind-loading or a warm-up can change things quickly — especially given the elevation spread between Ishiuchi Maruyama's base and summit.
Data sources
Ishiuchi Maruyama snow data is collected through a combination of on-mountain reports and weather forecasting services, giving you both official resort updates and independent forecast data in one place. The mountain is served by 15 lifts, including 4 quad chairlifts and a 6-person chairlift.
When to check
The biggest swings usually happen right after a storm. Check Ishiuchi Maruyama's report in the morning for the freshest numbers, and again in the afternoon as conditions evolve.
