The Overview
Michael Fulton
Melbourne-based skier and snowboarder with 50+ resorts across 5 continents. Specialises in Australian resorts and international resort comparisons.
Biwako Valley operates between 950 and 1,174 metres elevation on Mount Horai and Mount Uchimi in Shiga Prefecture's Hira mountain range. The resort spans 10 kilometres of piste across 8 runs with 224 metres of vertical drop. Terrain distribution breaks down to 30 per cent beginner, 60 per cent intermediate and 10 per cent advanced. The ski area receives an average of 3.5 metres of snow annually, supplemented by extensive snowmaking across all major trails to ensure consistent coverage throughout the season.
Intermediate runs dominate the layout, with the Horai Panorama course offering sweeping views across Lake Biwa whilst descending. The resort includes a half pipe, terrain park with progressive features, slalom course and mogul run. Beginners concentrate on the Uchimi Slope near the ropeway summit station, whilst the Horaikita Slope challenges advanced skiers. The compact 74-acre ski area sits across two connected peaks accessed via a network of chairlifts above the ropeway arrival point.
Biwako Valley draws heavy weekend crowds from Kyoto and Osaka, with queues forming at both the ropeway and chairlifts during peak periods. The base-free mountain operates with service desks scattered across the ski area rather than a centralised lodge. Biwako Terrace occupies the summit of Mount Uchimi at 1,100 metres, providing dining and observation facilities with floor-to-ceiling views across Japan's largest lake. Weekday visits offer significantly quieter slopes and faster lift access.
The resort functions primarily as a day-trip destination for Kansai region residents, positioned 40 kilometres from Kyoto and 89 kilometres from Osaka. No on-mountain accommodation exists, with lodging concentrated along the JR Kosei Line in Otsu City. The ski area suits beginners and intermediates seeking accessible skiing with distinctive scenery. Terrain park riders find well-maintained features and dedicated spotters, whilst advanced skiers typically find limited challenge across the modest vertical drop.

When to visit Biwako
The 2025-26 winter season operates from 5 December 2025 to 29 March 2026, with ski trail access beginning 27 December 2025. The resort typically runs for approximately 3.5 months, though exact opening and closing dates shift based on natural snowfall and snowmaking conditions. Biwako Terrace sightseeing operations commence 20 December ahead of ski terrain opening. Earlier pre-opening periods occasionally occur when snowfall permits advance trail preparation.
The ski area averages 3.5 metres of annual snowfall, modest by Japanese standards but adequate for the Kansai region's lower elevation resorts. The base elevation of 950 metres and summit of 1,174 metres create marginal snow reliability compared to resorts above 1,500 metres. Extensive snowmaking compensates for variable natural accumulation, with coverage across all major runs ensuring rideable conditions throughout the designated season. Late-season skiing typically faces temperature challenges as March arrives.
January delivers peak powder conditions, with the fourth week historically producing 23 centimetres across 4.3 snowy days. February maintains consistent coverage before March temperatures climb toward freezing during both day and night. Weekdays from mid-January through early February offer optimal combinations of snow quality and manageable crowds. Spring conditions deteriorate rapidly once temperatures consistently exceed zero degrees, with the snowpack becoming heavy and wet.
The resort does not schedule major competitive events or festivals during winter operations. Night skiing remains unavailable across all trails. Terrain park features receive regular grooming and maintenance, with staff monitoring jump landings throughout operating hours. The compact season length and metropolitan proximity create concentrated weekend demand, making midweek visits substantially more appealing for quality skiing without excessive queuing.

Getting there
Getting to Biwako, and where to stay
Biwako Valley sits on the western shore of Lake Biwa in the Hira mountain range within Otsu City, Shiga Prefecture. The resort occupies the slopes of Mount Uchimi at 1,108 metres and Mount Horai at 1,174 metres, approximately 1,100 metres above Japan's largest freshwater lake. The Kansai region location places the ski area 40 kilometres northeast of Kyoto and 89 kilometres from central Osaka. The surrounding Hira-Hiei mountains stretch 50 kilometres along Lake Biwa's western shoreline.
Shiga Station on the JR Kosei Line provides the nearest rail access, located on the western lakeshore. The station sits 40 minutes from Kyoto Station and connects via hourly bus service covering the final 10 minutes to the ropeway base station. Otsu City, Shiga Prefecture's capital, lies 15 kilometres south along Lake Biwa's shore. The resort has operated as a ski area and outdoor activity park since 1965, establishing itself as Kansai's most accessible skiing venue.
Road access follows the Meishin Expressway from Kyoto-Higashi Interchange, then Route 161 via Nishi-Ohtsu Bypass to Route 558. The drive from Kyoto-Higashi Interchange requires approximately 40 minutes under normal traffic conditions. Osaka drivers face 1.5 hours via the same expressway routing. The ropeway base station parking accommodates 1,700 vehicles, filling completely on winter weekends and holidays. Traffic congestion affects Route 558 approaches during peak periods.
Kansai International Airport sits 52 kilometres southwest of Osaka, approximately 90 kilometres from Biwako Valley via expressway connections. Osaka Itami Airport provides domestic service 10 kilometres north of central Osaka, roughly 70 kilometres from the resort. No direct airport shuttle services operate to Biwako Valley. Visitors typically transit through Kyoto Station via JR Haruka limited express from Kansai Airport, then transfer to the JR Kosei Line for Shiga Station. Total journey time from Kansai Airport approaches 2 hours using public transport.

Arizona Snowbowl's $1 Lift Tickets Are Hard to Find, but $9 Days Are Not
Arizona Snowbowl advertised eight $1 lift ticket days this winter. Go looking and only three are showing - 10 March, 1 April and 10 April - so the rest may already have gone. The consolation is a calendar full of $9 days, including all but one day in April. Opening day is 20 November, weather permitting, and opening weekend is $19.

Whitewater Brings Its Short Side Inbounds, With Six New Runs for 2026-27
For years, Whitewater's Short Side was where you ducked a rope and hoped for the best: unmapped, ungroomed and unpatrolled. This winter it's inbounds. Six new runs of glades and fall-line skiing add 190 acres (about 77 hectares), taking the resort past 1,400 acres in total. F2 Logging spent a month in the trees to make it happen, and opening day is pencilled in for 4 December. Bonanza now needs less snow to groom, too.

September Dusting Hits Mammoth Mountain Six Weeks Before Opening Day
Mammoth got its first snow of 2026-27 on Monday 28 September - and promptly lost it by Tuesday morning. Barely an inch fell at McCoy Station, but with opening day pencilled in for Friday 13 November, it's the first sign the Sierra is waking up. Last year's date slipped from 14 November to 20 November, so nobody's booking flights on a dusting just yet. Here's where California's early openers stand.

Four connected areas, 70 lifts and a World Championship course, yet Saalbach Hinterglemm still runs like a family holiday. Two days on snow and a Worlds Super-G later, here is who it suits, what the Ski ALPIN CARD covers and why Epic Pass holders should pay attention. Big on blues, light on steeps.

Sölden Plans Four-Race World Cup Opener on the Rettenbach Glacier from 2027
Sölden's World Cup opener has been two giant slaloms on the Rettenbach glacier for as long as most fans can remember. From 2027/28 it could be four. Director Jack Falkner wants to add two Super-Gs, backed by a nod from Vincent Kriechmayr, and turn the opening into a full week where the ski world gathers in the Ötztal. FIS and the ÖSV are yet to sign off. This year, it's still just the two GS races on 24 and 25 October.

Hokkaido Ski Resort Opening Dates 2026/27: Sapporo Kokusai Leads Off on 20 November
Hokkaido's lift season now has dates. Sapporo Kokusai opens first on 20 November, Niseko United, Kiroro, Rusutsu and Furano follow on 28 November, and Kamui closes the list on 12 December. Everything hinges on snow, and with a strong El Niño in play, the JMA gives Hokkaido's Japan Sea side a 40% chance of below-normal snowfall. Honshu's Japan Sea coast looks shakier.

Swiss Ski Resorts Post Second-Highest Winter Revenue on Record Despite a Warm Season
Switzerland logged 25.7 million ski days last winter, only 2.3% off the record, in a season that ranked sixth-warmest since records began. Revenue hit CHF 895.8 million, second only to 2024/25. Zermatt led on visits and takings, foreign guests hit a ten-year high, and 12 resorts never opened at all. Snowmaking, late storms and high altitude carried the numbers. Anything sitting at 1,000-1,200 m had a far rougher time.
