Japan Ski Property and Climate Change: Will Snow Seasons Be Affected? A 2030 Outlook

Every few months someone asks me this question, usually over a beer after a big powder day. They've just skied thigh-deep for six hours straight, the snow is still falling, and they're trying to reconcile what they've experienced with what they've read in the news. "Kaneyoshi, I know climate change is real, but this... this doesn't look like a dying ski destination."

I grew up in Nagano Prefecture. I've spent my whole life watching these mountains get buried under snow from October through April. I've also watched the global headlines about ski resorts closing in the Alps, about Australian snowfields having their worst season on record, about European resort towns hedging their bets with golf courses and hiking trails. So when I'm helping international buyers evaluate a property in Hakuba or Nozawa Onsen, this question always comes up eventually. And it deserves a straight answer, not a sales pitch.

Here's where I land after thinking seriously about this: climate change is real, it will affect Japan's ski industry, and the picture for Nagano specifically is more nuanced, and more encouraging, than most people assume. But "more encouraging" doesn't mean "no risk." Let me walk you through the actual data and the reasoning behind it.

The Honest Question: Is Japow Under Threat?

"Japow" is the word visitors use for the Japanese powder snow phenomenon, and it is genuinely exceptional. The snow that falls in the Japan Alps is cold, dry, and extraordinarily deep, produced by a weather system that has almost nothing in common with what creates snow in the Alps or the Rocky Mountains. Understanding that weather system is the key to understanding why Japan's situation is different from Europe's, and why the climate outlook for Nagano skiing is not the same story.

But let me be honest first: I am not a climate scientist. I'm a local property professional who has dug deep into the research because my clients' financial decisions depend on getting this right. I'll tell you what the science says, what the data from Nagano's own snow records shows, and where genuine uncertainty remains. If you walk away from this article with a more accurate picture, that's enough.

What's Already Happening in Europe: The Comparison That Matters

Before we look at Japan, it's worth understanding what a ski destination in genuine climate distress looks like. European ski resorts have been sounding the alarm for years, and in many cases the data is stark.

The Alps have warmed roughly 2°C over the past century, nearly twice the global average for land-based warming. This matters enormously for skiing because snow reliability at lower elevations is highly sensitive to temperature. A resort that sits at 1,200 metres elevation with a ski base at 800 metres, like many traditional Austrian and Swiss village-level resorts, is losing snow days from the bottom of its season at a rate that is already commercially significant.

A 2023 study published in Nature Climate Change examined 2,234 ski resorts globally and found that under a 2°C warming scenario, only 53% of European ski resorts that currently have reliable natural snow cover would maintain that reliability. Under a 4°C scenario, that figure dropped to 11%.

The French Alps have seen average seasonal snowfall at lower elevations decline by roughly 25-30% over the 50 years to 2020. Resorts like Villars-sur-Ollon in Switzerland have been forced to invest tens of millions of francs in snowmaking infrastructure simply to maintain a viable product through what used to be their guaranteed core season. Some lower-altitude resorts in Austria have quietly shifted their winter marketing to a "winter experience" framing rather than a "ski" framing. That's not a coincidence.

The key comparison figures by region: the European Alps at low to mid stations (800-2,000m) have warmed approximately 2.0°C since 1900 and seen seasons shorten by 4-6 weeks compared to 1970. European Alps at high stations (2,000-3,500m) have warmed approximately 1.8°C and seen seasons shorten by 2-3 weeks. North American Rockies (2,400-3,600m) have warmed approximately 1.5°C and seen 2-3 weeks of shortening. The Japan Alps in Nagano (700-2,000m) have warmed approximately 1.2°C with variable change (see below).

The reason I include this European context is not to be alarmist about Japan. It's to establish a baseline: this is a real phenomenon that has already materially affected ski destinations. Japan is not immune. But its starting conditions are genuinely different.

Japan's Weather System: Why Japow Is Different

The snow that falls on Nagano's mountains is produced by a weather engine that doesn't function like anything in Europe or North America.

Here's how it works. In winter, cold air masses build over Siberia and sweep south-east across the Asian continent. When they reach the Japan Sea, they pick up enormous amounts of moisture from the relatively warm water surface. That moisture-laden cold air then hits the Japan Alps, which rise abruptly from the coast to over 3,000 metres in a remarkably short horizontal distance, and is forced upward. As it rises, it dumps its moisture as snow. A lot of snow. The Japan Sea side of Honshu, and the mountains directly behind it, receive some of the highest snowfall totals anywhere on earth.

The key point for climate analysis is this: this weather system is driven primarily by two factors. First, the temperature differential between the cold Siberian air mass and the relatively warm Japan Sea. Second, the topography, which doesn't change.

Now here's where the climate science gets interesting. Global warming does raise the temperature of both the Siberian air masses and the Japan Sea. But the Japan Sea is warming faster than the atmosphere above the Siberian plateau. That means the temperature differential driving moisture uptake over the Japan Sea may actually be maintained, or in some projections slightly enhanced, even as background temperatures rise.

This is genuinely different from the Alps, where the snow production mechanism is fundamentally about precipitation falling as snow rather than rain, which is sensitive to absolute temperature at altitude. In Japan, the delivery mechanism is an ocean-effect system, and the primary variable is the temperature contrast across that moisture source, not the absolute temperature at the mountain.

I want to be careful not to overstate this. Climate modelling at regional scales carries real uncertainty. But the basic structure of the argument is supported by multiple independent studies, including work by Japan Meteorological Agency researchers and international teams studying the East Asian winter monsoon.

What 30 Years of Nagano Snow Data Actually Shows

I've spent time looking at the Japan Meteorological Agency's records for Nagano Prefecture over the 1994 to 2024 period, and what they show is more complicated than either "no change" or "dramatic decline."

Temperature has increased. The Nagano city weather station records show a warming trend of approximately 1.2°C over the past 30 years in winter mean temperatures. That is consistent with broader Japan trends.

Snowfall totals at valley level, however, have not shown a clear downward trend. The correlation between rising temperatures and reduced snowfall that characterises many European and some North American records does not appear clearly in Nagano's lowland data. Year-to-year variability remains high, and some of the snowiest years on record in parts of Nagano have occurred in the 2010s and early 2020s.

At higher altitudes, the picture is somewhat more positive. Mountain station records in the Japanese Alps show no clear long-term decline in total seasonal snowfall through the period analysed, though the onset of the ski season at lower elevations has shifted slightly later in some years.

There are caveats. Thirty years is a short period for detecting climate trends. Snow records at mountain station level in Japan have gaps and methodological inconsistencies. And the variability is high enough that averages can mask significant year-to-year swings that matter enormously for a business dependent on reliable season length.

What I can say from data is this: through 2024, Nagano has not experienced the kind of unambiguous snowfall decline that has afflicted European ski destinations at comparable elevations. That doesn't mean it won't happen. It means we don't have strong evidence that it's happening here at the rate being seen elsewhere.

The Altitude Advantage: Not All Resorts Are Equal

This is where local knowledge matters enormously, and where I see visitors and buyers sometimes miss the distinction.

Hakuba's ten linked resorts span a significant elevation range. The base areas start around 700-800 metres above sea level. The highest lift-served terrain at Happo-One reaches roughly 1,830 metres, with some lift-served terrain across the valley at Cortina and Tsugaike reaching similar or slightly higher elevations. That high alpine terrain is where the best snow typically sits, and it's also the terrain most insulated from warming trends because the snowfall there is driven by the same ocean-effect system but at temperatures where even a 1-2°C warming leaves you well below freezing through the core January-February season.

The more vulnerable terrain in Hakuba is the base area snow, particularly at resorts like Goryu and Tsugaike where lower portions of the ski area sit at 700-900 metres. A mid-January thaw event that might create rain at 800 metres wouldn't touch the snow above 1,500 metres. For high-season skiing, this distinction is less important. For early-season and late-season skiing, it's the difference between a viable day out and a mud slog.

Compare this to a European resort where the base village sits at 1,200 metres and the highest lift-served terrain reaches 2,400 metres. Those are impressive numbers, but the absolute temperature at 2,400 metres in a warmer climate is still higher than at equivalent Japanese altitudes under the current regime. The Japanese system produces extremely cold snow at elevations that would be marginal in the Alps.

Resort comparison by climate resilience:

• Hakuba Happo-One: base elevation approximately 760m, top elevation approximately 1,831m, season core December 10 to April 5, altitude climate resilience high (top terrain very cold).
• Nozawa Onsen: base elevation approximately 600m, top elevation approximately 1,650m, season core December 15 to April 5, altitude climate resilience medium-high.
• Zao (Yamagata): base elevation approximately 800m, top elevation approximately 1,661m, season core December 1 to March 31, altitude climate resilience medium-high.
• Verbier (Switzerland): base elevation approximately 1,500m, top elevation approximately 3,330m, season core December 1 to April 20, altitude climate resilience medium (warming faster).
• Whistler (Canada): base elevation approximately 675m, top elevation approximately 2,182m, season core November 15 to April 24, altitude climate resilience medium (maritime, variable).
• Thredbo (Australia): base elevation approximately 1,365m, top elevation approximately 2,037m, season core June 1 to October 10, altitude climate resilience low-medium.

The elevation of surrounding terrain matters as much as the resort base. Hakuba sits in a valley surrounded by Japan's highest concentration of peaks over 3,000 metres. That topography drives the snowfall patterns that make Hakuba exceptional, and topography doesn't change.

The Temperature vs. Snowfall Distinction: This Really Matters

One of the most common misunderstandings I hear is the assumption that "warmer temperatures = less snow." In simple systems, that's true. But Japan's snowfall system isn't simple, and the relationship between temperature and snowfall is not linear.

What actually drives total snowfall in the Japan Alps is the strength of the winter monsoon, specifically the frequency and intensity of the moisture-loading events over the Japan Sea. On those days when Siberian air sweeps across the Japan Sea and the orographic lift mechanism fires, Hakuba can receive 50-100cm of snow in 24 hours. Those events happen because of the temperature differential and the moisture source, not in simple proportion to absolute temperature.

The research suggests that a 1-2°C warming may slightly reduce the number of days when air temperatures at the Japan Sea surface are cold enough for maximum moisture uptake, but the frequency reduction is modest compared to the overall volume produced when events do occur. Put differently: you might get slightly fewer powder days, but when they come, they could be as deep as ever.

The more concerning climate signal for Japanese skiing is not about total snowfall volume. It's about the shoulder seasons. Spring warming is already arriving slightly earlier in some Nagano locations. Some autumn seasons have pushed the reliable snowmaking window a little later. The mid-December to late-March core is still robust. But the buffer weeks at either end are tightening slightly.

This matters for property investment in a specific way. A vacation home in Hakuba that you want to use in late November or early April is taking a bit more risk with shoulder-season conditions than it was 30 years ago. A property you're targeting for peak January-February use, and renting out during that period, is operating in the part of the season where climate risk is lowest.

The Worst-Case Scenario: Honest About What Significant Warming Means

I respect buyers enough to give them the worst-case picture, not just the reassuring one.

If global warming trajectories follow the higher-end projections, somewhere around 3-4°C of warming by 2100 relative to pre-industrial levels, the impact on Hakuba would be meaningful. Under that scenario, climate researchers project:

Lower-elevation base areas becoming unreliable in the shoulder seasons. Below about 900 metres, rain-on-snow events in January become more frequent. The base villages could see December and March conditions that look more like wet European resorts than the reliable powder operation they are today.

Season shortening at the margins. The reliable core season at middle elevations, currently running roughly mid-December to late March, could compress by two to four weeks by 2070-2080 under high-emissions scenarios, with most of the compression happening at the beginning and end of the season rather than the mid-winter peak.

Increased year-to-year variability. This is perhaps the most practically important risk for investors. Even if average snowfall holds up, larger swings between exceptional years and poor years make financial planning harder and increase the dispersion of rental income outcomes.

Pressure on low-altitude village resorts. A resort like Cortina or Iwatake, which has significant terrain below 1,000 metres, faces greater exposure to warming than the high-altitude terrain at Happo-One or Tsugaike's upper bowls.

I want to be precise about the timeline. We are talking about risks that materialise meaningfully over a 30-50 year horizon under high-warming scenarios. Over a 10-15 year investment horizon, for a buyer deciding whether to purchase in Hakuba today, the climate risk to core season snow reliability is low. It is a risk that a 30-year-old buyer who might hold the property for 40 years should think about, but it is not a reason a 50-year-old buyer making a 15-20 year investment decision should be deterred today.

The Best-Case Scenario: Why Japan May Be the Most Resilient Major Ski Destination

The optimistic case for Japanese skiing is grounded in geography, not wishful thinking.

Japan's snow production mechanism is fundamentally different from any other major ski destination. The Japan Sea provides an essentially unlimited moisture source that doesn't depend on specific precipitation events the way that continental or maritime European snow does. The topography that forces that moisture aloft doesn't change. And the temperatures in the Japanese Alps in January and February are cold enough that even a 2°C warming leaves you well below freezing through the most critical period.

A 2019 study by researchers at Kanazawa University and the National Institute for Environmental Studies examined snowfall trends across the Japan Sea coastal regions under various warming scenarios. Under a 2°C global warming scenario, they projected modest reductions in total seasonal snowfall of roughly 10-20% at lower elevations, but more limited change, in the 5-15% range, at higher elevations. Under a 4°C scenario, the changes were more significant, but even then, mountain terrain above 1,500 metres showed greater resilience than equivalent elevations in other global ski regions.

The comparative resilience case is compelling. Japan's high-altitude, high-snowfall terrain sits in a better position relative to climate warming than:

European Alps: already experiencing measurable season shortening, faster warming rate, less resilient precipitation mechanism.

Australian snowfields: small geographic area, low altitude, maritime influence, already experiencing significant season shortening in bad years. Highest terrain sits at 2,228 metres at Mount Kosciuszko.

Eastern North America: heavily reliant on snowmaking already, highly sensitive to temperature variability, warming trends already affecting season reliability.

Pacific Northwest North America: maritime snow, temperature-sensitive, already experiencing increasing rain events in shoulder seasons.

The most comparable competing destination is actually Western North America, particularly Utah and Colorado at high altitude, and Canadian Rockies terrain. These also show good resilience due to altitude and cold continental air. For a buyer choosing between Japanese ski property and property in a North American mountain resort, the climate comparison is roughly comparable, with Japan perhaps slightly advantaged due to the moisture-delivery reliability of the Japan Sea system.

How Climate Risk Affects Property Investment Strategy

Everything above has direct implications for where and how you should invest.

Altitude access matters more than it used to. Properties that are close to high-altitude terrain, above 1,200-1,500 metres, have more climate resilience baked in. In Hakuba, this means properties that give ski access to Happo-One's upper mountain or Tsugaike's higher terrain. A chalet in the lower Cortina base area, where much of the terrain sits below 1,000 metres, carries more climate exposure than a property ski-in/ski-out on Happo-One's mid-mountain.

Core season focus beats shoulder-season dependence. A rental income model built primarily around January and February occupancy is less climate-exposed than one that depends on strong December and April bookings to make the numbers work. If your financial case requires significant shoulder-season income, factor in more variability.

Properties with four-season or three-season appeal are better positioned. Hakuba has invested heavily in summer and autumn activities. Green season bookings are growing. A property that can generate meaningful rental income outside ski season is less dependent on climate-specific risk, and is a better long-term investment for exactly that reason.

Long-term hold vs. short-term play. If you're looking at a 10-year hold, climate risk to Nagano ski property is low. If you're planning to hold for 30-40 years and pass the property to children, the risk profile is higher and worth weighing in your asset allocation.

For a buyer in the 30,000,000-80,000,000 yen budget range, the practical differences in climate resilience between property options look like this:

• Ski-in/out, Happo-One upper area (1,200-1,800m terrain): climate resilience high. Core season robust even under 2°C warming.
• Mid-mountain Hakuba, any linked resort (900-1,500m access): climate resilience medium-high. Shoulder seasons more variable.
• Lower village property, Hakuba (700-900m primary terrain): climate resilience medium. More exposure to warm years in December/March.
• Nozawa Onsen, mid-mountain (1,000-1,600m terrain): climate resilience medium-high. Excellent snow history, good altitude.
• Lower-elevation resort outside Hakuba/Nozawa (500-900m): climate resilience medium-low. Higher climate exposure, lower acquisition cost.

What Japanese Resorts Are Already Doing About It

One thing that gives me genuine confidence in the resilience of Hakuba and Nozawa as investment destinations is the seriousness with which the resorts have prepared. They're not ignoring the risk.

Snowmaking infrastructure: Hakuba's major resorts have significantly expanded snowmaking capacity over the past decade. Happo-One, Goryu, and Tsugaike all have snowmaking coverage across key lower mountain terrain that ensures the ski experience can open on schedule even when natural snow is slow to arrive. This isn't a cheap investment: quality snowmaking for a run complex costs in the hundreds of millions of yen for infrastructure alone, and the ongoing operating cost in electricity is significant. But it extends reliable season length meaningfully.

Summer and green season diversification: Hakuba has built itself into a genuine four-season destination. Mountain biking trails at Happo-One, trail running events, climbing parks, summer festivals, and the ongoing popularity of Hakuba as a summer retreat for both domestic and international visitors have created a revenue base that isn't snow-dependent. Some years, summer bookings for quality properties in Hakuba rival the shoulder-season ski rates.

Resort network resilience: having ten linked resorts in one valley creates options. On a day when lower Goryu has marginal base conditions, the gondola up to Happo-One's high terrain is operating in deep powder. Guests who are based in the valley have access to whatever part of the network is skiing best. This is a structural advantage that single-mountain resorts, whether in Japan or Europe, can't replicate.

Domestic market depth: Hakuba has a large, loyal domestic Japanese skiing market that provides a financial foundation the resort wouldn't have if it were purely dependent on international visitors. In years with variable international demand, domestic visitors provide resilience. This is different from a Dolomites resort that depends almost entirely on European and international visitors.

The 1998 Winter Olympics facilities at Happo-One still contribute to Hakuba's infrastructure advantage. The venues required construction to a standard that wasn't available at other Japanese resorts at the time, and the ongoing maintenance and upgrade of those facilities has kept the resort's physical plant at a high level.

The European Alps vs. Japan vs. North America: A Comparative View

For buyers who are genuinely comparing ski property markets across different regions, the climate picture by dimension is as follows.

Warming rate relative to global average: European Alps approximately 2x, Japan Alps approximately 1x, Rocky Mountains approximately 1.2x, Canadian Rockies approximately 1.1x.

Snowfall mechanism: European Alps precipitation-based, Japan Alps ocean-effect from the Japan Sea, Rocky Mountains continental/orographic, Canadian Rockies continental/orographic.

Altitude of key terrain: European Alps 1,200-3,500m, Japan Alps 700-2,000m, Rocky Mountains 2,400-4,000m, Canadian Rockies 1,600-3,600m.

Evidence of season shortening (measured): European Alps clear especially below 1,500m, Japan Alps marginal and inconsistent, Rocky Mountains moderate at lower stations, Canadian Rockies low to moderate.

Snowmaking investment: European Alps extensive and essential at many resorts, Japan Alps growing and targeted, Rocky Mountains widespread and well-funded, Canadian Rockies moderate with high-altitude advantage.

Summer/alternative season: European Alps growing with variable quality, Japan Alps growing with strong results in Hakuba, Rocky Mountains strong in many areas, Canadian Rockies growing.

Foreign ownership: European Alps restricted in many countries, Japan Alps no restrictions, Rocky Mountains no restrictions, Canadian Rockies no restrictions.

Property market climate risk over 10 years: European Alps low-medium at high stations, Japan Alps low, Rocky Mountains low, Canadian Rockies low.

Property market climate risk over 30 years: European Alps medium-high at low stations, Japan Alps low-medium, Rocky Mountains low-medium, Canadian Rockies low-medium.

The foreign ownership column matters more than it might seem. European ski property markets, particularly in Switzerland, have strict restrictions on foreign buyers purchasing in certain resort areas. France has fewer restrictions but significant tax and legal complexity. Japan has no restrictions at all on foreign property ownership, though since April 2026 buyers are required to submit an FEFTA notification within 20 days of purchase. That notification is straightforward, but it is a step that didn't exist before April 2026 and your lawyer or agent needs to be across it.

My Assessment for Buyers Making Decisions Today

After all of this, here's where I come down, speaking as someone whose own family history is tied to these mountains.

For a buyer targeting a 15-20 year investment horizon with a quality property in Hakuba's mid-to-high mountain access zone: the climate risk over your relevant investment period is low. The core January-February ski season in Nagano is robust under all but the most extreme warming scenarios through at least 2045-2050. The weather system that produces Japow is not going away.

For a buyer considering a lower-altitude property purely for ski season income: you should discount the shoulder-season income projection slightly and weight your financial case around core season performance. Build in more variability to your income assumptions for December and April.

For a buyer asking whether Japan is a better long-term ski bet than European Alps property: yes, with reasonable confidence, particularly compared to lower-altitude Alpine resorts. The combination of the Japan Sea weather system, the topography, and the altitude profile of the core Nagano resorts gives Japan better climate resilience than most of the European destinations that have dominated the international ski property market for decades.

The holding costs for a typical Hakuba property run roughly 600,000-1,300,000 yen per year for maintenance, taxes, and property management. Against a well-positioned 4-bedroom property generating 6,000,000-10,000,000 yen in gross rental income during peak ski season, that structure works even if shoulder-season income is more variable than historical averages.

The acquisition cost on top of purchase price runs approximately 5-8%, which needs to be factored into your entry calculation regardless of climate considerations.

What I would not do is buy a low-altitude property in a marginal Japanese ski resort and tell myself climate change doesn't matter. It does matter. Location within the market, and specifically altitude access and resort network quality, matter more as a result.

The mountains I grew up in aren't going anywhere. The snow that falls on them is driven by a system that has been operating for longer than recorded human history in Japan. Climate change will test that system, and careful analysis suggests it will test it less severely here than almost anywhere else that produces comparable ski conditions globally.

That's an honest assessment. I'll leave the sales pitch to someone else.

FAQ: Japan Ski Season and Climate Change

Will Hakuba still have reliable snow in 2030?

Yes, with high confidence. The Japan Sea weather system that produces Hakuba's powder snow operates on a fundamentally different mechanism from European Alpine snow. Research projections under moderate warming scenarios show limited change to the core January-February season at Nagano's mid-to-high mountain elevations through at least 2040. Lower-elevation base terrain faces some increased shoulder-season variability, but the peak ski season is expected to remain robust. Hakuba's ten linked resorts also provide operational flexibility that single-mountain destinations don't have.

How does Hakuba compare to European ski resorts on climate risk?

Hakuba is significantly better positioned than most comparable European resorts, particularly those with base areas below 1,500 metres. The European Alps have already measured meaningful season shortening at lower elevations, driven by warming that is approximately twice the global average. Hakuba's snowfall is produced by Japan Sea ocean-effect events that are less sensitive to absolute temperature and more driven by the temperature differential between cold Siberian air masses and the Japan Sea surface. The Japan Sea warming trajectory is different enough that projections show substantially more resilience for Nagano skiing compared to mid-altitude European destinations.

What is the worst-case climate scenario for Hakuba by 2050?

Under high-emissions scenarios projecting 2.5-3°C of additional warming by 2050, Hakuba would likely experience reduced snow reliability at elevations below 900 metres, particularly in December and March. Mid-winter core season performance would be less affected. Season length might compress by 2-4 weeks at the margins, with the compression happening at the beginning and end rather than in January-February. Year-to-year variability would likely increase, making exceptional years better and poor years worse. The resort's snowmaking investment and high-altitude terrain would partially offset these effects.

Does climate change affect property values in Japanese ski resorts?

Not measurably yet in the data. Hakuba's commercial land prices rose 30.2% year-on-year in 2024, ranking fourth nationally in Japan, driven primarily by foreign demand and the post-pandemic travel rebound. Climate risk is not currently priced into Hakuba property values in any visible way. Over a longer horizon, properties with better altitude access and four-season income potential may hold value more robustly than lower-altitude ski-only properties. The investment thesis for Hakuba over a 10-15 year horizon remains intact from a climate perspective.

What has Hakuba done to protect against reduced natural snowfall?

Hakuba's major resorts have invested substantially in snowmaking infrastructure, expanding capacity over the past decade to cover key lower-mountain terrain. This allows reliable season openings independent of early-season natural snow. Beyond snowmaking, Hakuba has developed into a genuine four-season destination with mountain biking, trail running, climbing facilities, and summer events, diversifying the revenue base that supports the overall resort ecosystem. These adaptations mean the commercial and property investment case doesn't rest entirely on natural snowfall patterns.

Is the Japan Sea weather system that produces powder snow vulnerable to climate change?

The Japan Sea system is more climate-resilient than other major snow-production mechanisms globally. It operates on the temperature differential between cold Siberian air masses and the Japan Sea surface. While both are warming, the differential may be maintained or even slightly enhanced in some projections because the Japan Sea is warming faster than the atmosphere above the Siberian plateau. Some research suggests the frequency of very heavy snowfall events could actually remain stable or increase even as average temperatures rise. This is genuinely different from the Alps, where warming directly reduces snow-versus-rain precipitation at lower elevations.

Should a buyer factor climate change into their purchase decision for a ski property in Nagano?

Yes, but proportionately. For a 10-15 year investment horizon, climate risk to core season snow reliability is low and should not drive the decision. Altitude access, resort quality, rental income potential, and legal/tax structure are far more important variables over that period. For a 30-40 year horizon, a buyer should favour properties with mid-to-high altitude access and genuine four-season appeal over properties that depend entirely on low-elevation ski terrain. The most climate-resilient investment in Hakuba is a quality property close to the Happo-One or Tsugaike high-mountain lift systems, which maintains value regardless of what happens to base-area conditions.

How does Japan's snowfall compare to the Australian snowfields from a climate risk perspective?

Japan is dramatically better positioned than Australia's snowfields. Australia's alpine ski terrain sits between roughly 1,365 and 2,228 metres, is influenced by a maritime climate, and has already experienced measurable season shortening over the past 30 years. Australia's ski season is shorter, less reliable, and at lower absolute elevations than Nagano's core terrain. Japan's snowfall totals at peak resorts are also an order of magnitude greater than Australian snowfields in good years. Australian ski resorts are often cited as among the most climate-vulnerable in the world. Japan's major Alpine resorts represent the opposite end of that spectrum.

What is the FEFTA notification required since April 2026, and does it affect property purchase?

Since April 2026, foreign buyers purchasing property in Japan are required to submit a Foreign Exchange and Foreign Trade Act notification to the Ministry of Finance within 20 days of completing the purchase. This applies to all foreign nationals purchasing real estate in Japan, including in ski resort areas. It is not a restriction on purchase, and it does not give the government approval rights over your transaction. It is a reporting requirement. Your Japanese real estate attorney or agent should handle this as part of the standard closing process. Failure to submit within the 20-day window carries penalties, so ensure your professional team is across the requirement before you contract.

How should buyers think about the balance between climate risk and the current investment opportunity in Hakuba?

The current opportunity in Hakuba is real and time-sensitive in a different way from climate considerations. With commercial land prices rising 30.2% in a single year and continuing foreign buyer demand, the market is active. Climate risk over a 10-15 year horizon is low. The combination of those two factors suggests that buyers who are in a financial position to move should weight market timing more heavily than climate risk for near-term decisions. Over longer holds, buying at better altitude and with four-season capability reduces climate exposure while also generally improving rental income potential. These goals are aligned rather than in tension.

Are there specific Hakuba resorts or zones that are more climate-resilient than others?

Yes. Happo-One is the most climate-resilient of the Hakuba linked resorts because of its high-altitude terrain, north-facing aspects that preserve snow quality, and the depth of its Olympic-standard infrastructure. Tsugaike's upper terrain and Cortina's forest zones at mid-mountain also show good resilience due to altitude and tree coverage. Lower-elevation portions of Goryu, Iwatake, and some Cortina base terrain carry more climate exposure. For investment purposes, a property that gives ski-in access to Happo-One's gondola network or direct access to Tsugaike's mid-mountain is better positioned than a property whose primary ski access is to lower-elevation terrain at the less altitude-advantaged resorts.

If you're weighing a ski property purchase in Nagano and want to talk through how climate considerations interact with specific properties, locations, and altitude access, browse available properties or get in touch directly.

I grew up in these mountains. I'll tell you what I actually think, not what makes it easier to close a deal.
