As of April 1, 2026, Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) designates 532 municipalities in 24 prefectures as heavy-snow areas (豪雪地帯), 201 of which are special heavy-snow areas (特別豪雪地帯). Counting the lodging facilities listed on major booking sites in municipalities whose entire area or most of it is designated, we find 7,323 properties with 270,263 rooms. On top of heating and hot-water energy costs, a snow-country property faces a recurring winter bill for physically moving snow: mechanical clearing of parking lots, snow-melting systems at the entrance, and clearing snow off the roof. This article focuses on those three cost items. We estimate the number of clearing call-outs from the Japan Meteorological Agency (JMA) snowfall normals, build up the annual cost per room for three snowfall tiers, and divide it by winter sales derived from the December–February estimated settled ADR and occupancy. Finally, we lay out the break-even between staying open in winter and switching to seasonal operation, and the payback on snow-melting equipment.

270,000 Rooms Inside the Designated Areas — 60% in the 10 Fully Designated Prefectures

First, the size of the population bearing these costs. Designations under the Act on Special Measures for Heavy Snowfall Areas are made by municipality. Ten prefectures—Hokkaido, Aomori, Iwate, Akita, Yamagata, Niigata, Toyama, Ishikawa, Fukui and Tottori—are designated in their entirety, and the remaining 14 have some municipalities designated. Table 1 matches these designated areas, municipality by municipality, against the lodging facilities listed on major booking sites within MetroEngines Research’s coverage.

Properties in municipalities that are wholly or mostly designated total 7,323 properties and 270,263 rooms, of which 3,479 properties and 99,126 rooms are associated with special heavy-snow areas. Separately, municipalities only partly designated (such as Sendai, Shizuoka and Fukushima City) have 1,689 properties and 74,095 rooms; because we cannot tell at the municipal level whether a property sits inside or outside the designated area, these are shown separately as reference values in Table 1 (in the tier-level estimates later, only Fukushima City and Omachi, which correspond to a representative observation station, are included). By prefecture, Hokkaido stands out with 82,854 rooms, followed by Niigata (28,040), Ishikawa (18,641), Nagano (18,250) and Iwate (16,320). Within special heavy-snow areas alone, Nagano (17,938 rooms) and Niigata (17,282 rooms) are the two largest clusters—reflecting how ski resorts and onsen towns overlap with the special heavy-snow designations.

Designated municipality counts are from MLIT, “Designation of Heavy-Snow and Special Heavy-Snow Areas (as of April 1, 2026).” Property and room counts are from MetroEngines Research (operating properties listed on major booking sites, N=9,012 properties / 344,358 rooms; wards of ordinance-designated cities are aggregated into their city). “Wholly or mostly designated” covers municipalities designated entirely as heavy-snow or special heavy-snow areas, and those partly special heavy-snow and otherwise heavy-snow. “Partly designated” covers municipalities where only part is a heavy-snow area and most is undesignated.

Back-Calculating Call-Outs from Snowfall Normals — Tokamachi 48, Sapporo 24, Niigata 7

The cost of moving snow is driven almost entirely by how many times you have to move it. JMA normals are useful here. Annual total snowfall depth (cm) measures the total amount of snow that falls on a site over a winter, and if a machine is sent out for every fixed amount of fresh snow, it converts into a number of call-outs. Municipal road clearing commonly uses about 10 cm of fresh snow as the call-out trigger. Sapporo City’s specification for clearing facility parking lots dispatches crews when snow depth exceeds 10 cm and vehicles can no longer move easily, and it budgets 14 call-outs a year (3 in December, 5 in January, 5 in February and 1 in March, about one hour each). Sapporo’s normal total snowfall is 479 cm, so public-facility operations work out to one call-out per roughly 34 cm of snowfall.

Lodging is different. Guests arrive and depart in the morning and evening, and the entrance and parking lot must be usable every morning, so the call-out threshold is lower than for public facilities. We use “total snowfall depth ÷ 20 cm” as our estimating formula, which gives 24 call-outs in Sapporo—about 1.7 times the public-facility specification. In the sensitivity analysis, this factor ranges from 15 cm (more call-outs) to 30 cm (similar to public facilities). Table 2 shows the normals and estimated call-outs for key observation stations. Tokamachi (967 cm) needs 48, Yuzawa (1,054 cm) 53, and Hijiori in Okura Village (1,469 cm) 73, while Niigata City (139 cm) needs only 7 and Kanazawa (157 cm) 8. Even within Niigata Prefecture, call-outs differ sevenfold between Niigata City and Tokamachi.

The tier values used in the estimates are 1,000 cm snowfall / 200 cm maximum depth for heavy snow, 500 cm / 100 cm for medium snow, and 150 cm / 35 cm for light snow

Assumptions for the Three Cost Items — Unit Costs from Public Sources, Frequencies from Normals

The model property has 60 rooms, 1,500 square meters of parking and approach, 150 square meters of road heating and 1,200 square meters of roof. We also show a 30-room model (900/100/700 square meters) and a 120-room model (2,400/200/2,000 square meters). Unit-cost assumptions are in Table 3; each starts from a figure in a public source, and those involving estimation are labeled as such. For the mechanical clearing contract rate, Nagano Prefecture’s FY2025 construction design unit prices set an hourly rate of ¥1,600 for a snow-removal dozer (wheel type, 7-ton class; machine management cost of ¥779,000 per unit charged separately), ¥26,711 per worker-day for a (special) operator and ¥24,341 for a general laborer. Adding fuel, depreciation and the overheads of private contracts, including standby and guaranteed call-outs, we estimate ¥15,000 per hour. Road heating is assumed to be electric: we adopt the 200–250 W per square meter heat supply in a Hokkaido Industrial Research Institute report and an electricity price of ¥22.8/kWh, the average high-voltage level in the Agency for Natural Resources and Energy’s Electric Power Statistics (the same assumption as our article on winter heating costs). Because electric systems also carry heavy demand charges based on contracted capacity, we add a demand-charge equivalent equal to the energy charge (an editorial assumption).

Roof snow clearing is assumed to be manual. We use an estimated productivity of 100 square meters per worker-day (for about 1 m of snow), and apply an overhead factor of 1.3 for safety equipment, insurance and supervision to the ¥24,341 general-laborer wage, giving about ¥31,600 per worker-day. We assume 4 clearings a year in heavy snow, 1 in medium snow and none in light snow. In February 2026, Nagaoka City expanded its roof-snow-clearing subsidy for households needing assistance, raising the number of subsidized clearings per winter from 3 to 5—consistent with our assumption of 3–5 clearings a year in heavy-snow areas. Iwamizawa City’s subsidy covers half the cost up to ¥20,000 per clearing, implying a market rate of around ¥40,000 per clearing for an ordinary house. Snow hauling, the cost of trucking snow away once on-site storage space runs out, is assumed at 6 times a year in heavy snow and 2 in medium snow.

Annual Cost per Room: ¥79,100 Heavy, ¥38,300 Medium, ¥16,600 Light — Three Items Split Almost Evenly

Figure 2 and Table 4 show the results. In heavy snow, the 60-room model costs ¥4.74 million a year, or ¥79,100 per room. The breakdown—mechanical clearing including hauling ¥26,600, road heating (operation plus depreciation) ¥25,200, and roof snow clearing ¥27,300—splits almost evenly across the three items. In medium snow the cost is ¥38,300 per room, with the mix shifting toward road heating as roof clearing falls to once a year. In light snow it is just ¥16,600, more than 80% of which is road heating: even where little snow needs moving, the equipment that keeps the approach safe runs all winter.

Property size also matters a great deal. In the same heavy-snow tier, the 30-room model costs ¥99,000 per room and the 120-room model ¥60,100—a 1.6x gap. Parking, roof and approach areas do not grow in proportion to the number of rooms, so smaller properties carry more area per room. This is the same pattern we pointed out for total costs including structure and heating in our article on hotel costs in heavy-snow areas, and it reappears when we look only at the three snow-moving items.

Road heating is the sum of operating cost (energy charge plus demand-charge equivalent) and equipment depreciation. Energy costs for heating and hot water are not included

We test the uncertainty in the assumptions with a sensitivity analysis. Starting from ¥79,100 for the heavy-snow 60-room model, narrowing the call-out factor to 15 cm gives ¥85,300, and widening it to 30 cm gives ¥72,800. Varying the labor rate by 30% gives ¥71,500–¥86,700, the electricity price ¥73,500–¥84,600, and the mechanical clearing contract rate ¥73,400–¥84,700. Whichever assumption we move, the annual cost per room stays within ¥70,000–¥87,000, so the conclusion of roughly ¥80,000 per room a year in heavy snow holds.

Beyond moving each assumption individually, we also check the bounds when all of them move in the same direction. Table 5 shows three scenarios for the heavy-snow 60-room model, with the call-out factor and the three unit costs moved together toward the optimistic or pessimistic side. Even the pessimistic scenario comes to ¥106,000 per room a year, 11.5% of winter sales (weighted ADR), or 15.8% with median ADR as the denominator. The optimistic scenario drops to ¥55,900, or 6.1%. The cost range spans about 1.9x, but in every scenario the cost stays below 10–20% of winter sales.

Source: HotelBank Editorial Team estimates (Table 3 assumptions varied simultaneously). Snow hauling, roof clearing frequency and equipment depreciation are common to all scenarios. Winter sales per room = weighted ADR ¥22,151 or median ADR ¥16,146 × occupancy 46.1% (Japan Tourism Agency, average of January, February and December 2025) × 90 days. Each item rounded to the nearest ¥100

Share of Winter Sales: 8.6% Heavy, 5.6% Medium, 4.3% Light — The Rate Sets the Denominator

Next, we look at how much of winter sales these costs represent. For the denominator, we multiply the December–February estimated settled ADR of the municipalities in each tier (weighted by rooms) by prefectural occupancy from the Japan Tourism Agency’s Overnight Travel Statistics Survey (average of January, February and December 2025), giving 90 days of winter sales per room. In the 13 heavy-snow municipalities (N=754 properties / 15,473 rooms), weighted winter ADR is ¥22,200 and occupancy 46.1%, for winter sales of ¥919,000 per room. The 20 medium-snow municipalities (N=1,475 properties / 73,903 rooms) come to ¥13,800 and 54.8%, or ¥680,500; the 13 light-snow municipalities (N=983 properties / 55,483 rooms) to ¥9,700 and 44.7%, or ¥389,500.

Applying the annual costs in Table 4, the share of winter sales for the 60-room model is 8.6% in heavy snow, 5.6% in medium snow and 4.3% in light snow. The 30-room model reaches 10.8% in heavy snow and the 120-room model 6.5%. However, the heavy-snow weighted ADR is pulled up by Kutchan (¥53,700), Niseko (¥38,600) and Yuzawa (¥21,800); the typical municipality in the tier, measured by the median, is only ¥16,100. Using median ADR as the denominator, the heavy-snow 60-room share rises to 11.8%. Medium snow is similar: a weighted ¥13,800 against a median ¥8,700, putting the median-based share at 8.9%. The cost of moving snow is set by snowfall, but how heavily it weighs is set by the rate.

Tiers are based on total snowfall depth (normals) at each municipality’s representative observation station (heavy: 800 cm or more; medium: 300–800 cm; light: under 300 cm). Winter ADR is the December 2025 – February 2026 estimated settled ADR (finalized historical basis), weighted by municipal room count, alongside the municipal median; the estimated settled ADR covers 228 properties in heavy snow, 830 in medium snow and 725 in light snow (sum of the 3-month minimums). Occupancy approximates municipal values by applying prefectural figures from the Japan Tourism Agency’s Overnight Travel Statistics Survey.

Moving the two components of the denominator together makes it easier to see where the cost burden shifts. Table 7 fixes the heavy-snow 60-room annual cost at ¥79,100 and shows the share of winter sales for each combination of winter ADR and occupancy. A property with a winter ADR of ¥12,000 and 40% occupancy reaches 18.3%, while one at ¥30,000 and 55% stays at 5.3%. At occupancy of around 46%, the threshold for keeping the share under 10% lies at an ADR between ¥16,000 and ¥22,000; at a winter ADR of ¥8,000, even 65% occupancy (an assumed winter value) gives 16.9%. Preparing for snow costs depends first on winter rate design rather than occupancy.

Cost share = cost of moving snow (¥79,100 per room a year) ÷ (winter ADR × occupancy × 90 days). The shaded cell is the heavy-snow base case (weighted ADR ¥22,151, occupancy 46.1%). Winter ADR is the estimated settled ADR (December 2025 – February 2026); 46.1% occupancy is the tier-weighted average of the Japan Tourism Agency’s Overnight Travel Statistics Survey for January, February and December 2025.

The Break-Even for Opening in Winter Is 8–14% Occupancy — Measure Snow-Melting Capex Payback in Operating Days

Finally, we set out the break-even between properties that stay open in winter and those that switch to seasonal operation. If a property closes for winter, it avoids the snow costs other than equipment depreciation, as well as energy costs for heating and hot water. If it stays open, it must recover these from the contribution margin of rooms sold after variable costs (linen, amenities, sales commissions, etc., assumed here at 30% of ADR). For energy costs we use the figures from our estimate for the era of ¥140/L kerosene: ¥15,202 per room per month for a ryokan-type property (¥45,600 for December–February) and ¥3,794 per month for a business-hotel type (¥11,400 for the same period).

Under these conditions, the break-even winter occupancy for the 60-room model at median ADR is 11.6% in heavy snow, 14.1% in medium snow and 10.6% in light snow (all with ryokan-type energy costs), as shown in Table 8. With business-hotel energy costs it falls to 8.2%, 7.8% and 4.1%. Actual occupancy in each tier is 44–55%, so for a property achieving its tier’s typical rate there is little arithmetic case for closing in winter because of snow costs. The break-even rises not where there is more snow but where the rate is low. At 30% occupancy, the break-even winter ADR is ¥6,200 in heavy snow and ¥4,100 in medium snow; for properties that can only sell below these levels, seasonal operation becomes an option, together with the difficulty of securing staff. Which municipalities concentrate the properties that close in winter is covered by prefecture in our article on seasonal swings in listings; this article supplies the cost side of that decision.

Break-even occupancy = (snow costs excluding depreciation + winter energy costs) ÷ (winter ADR × 70% contribution margin × 90 days). Energy costs are ¥45,600 for ryokan type and ¥11,400 for business-hotel type (per room, December–February). A simplified estimate that excludes year-round fixed costs such as labor.

What about the payback on snow-melting equipment? Installing roof snow melting over 1,200 square meters costs ¥30 million, or ¥2 million a year over 15 years of depreciation, with operating costs of ¥2.46 million a year in heavy snow. The manual roof clearing it replaces costs ¥1.64 million a year in heavy snow; for manual labor to exceed the combined ¥4.46 million of depreciation and operating cost, the labor rate would need to be 2.7 times today’s level. In other words, even in heavy snow, roof snow melting struggles to pay back from savings on roof clearing alone. Road heating is the same: against ¥6 million of equipment for 150 square meters and ¥1.11 million a year to operate, the mechanical clearing it replaces amounts to only a small amount of machine time for the same area.

So we change the yardstick for payback to “how many operating days can it protect?” For the heavy-snow 60-room model, winter sales per day are about ¥613,000 (ADR ¥22,151 × 46.1% occupancy × 60 rooms). The ¥2.82 million net annual cost increase for roof snow melting equals 4.6 days of this, and ¥1.40 million for road heating equals 2.3 days. If a property can avoid a combined five days over the winter of closures for roof clearing or lost arrivals due to icing at the entrance, roof snow melting pays for itself. In medium snow, sales per day fall to ¥454,000, and the required days rise to 6.8 for roof snow melting and 2.5 for road heating. Expressed as payback years—recovering ¥30 million of equipment through sales protected beyond the net annual cost increase—protecting 10 operating days a year gives about 9 years in heavy snow, and 15 days about 5 years. The value of snow-melting equipment lies not in cost savings but in insurance that keeps winter operations uninterrupted.

Roof snow melting operating cost = 150 W per square meter × operating hours × ¥22.8/kWh, plus an equal demand-charge equivalent. Replaced costs are manual roof clearing (item c in Table 4) for roof snow melting, and mechanical clearing for the same area (assumed at 10% of mechanical clearing cost) for road heating. Winter sales per day = winter ADR (weighted) × occupancy × 60 rooms. Source: HotelBank Editorial Team estimates

Implications for Operators — Design for Fewer Call-Outs, and Design to Absorb Costs Through Rate

To summarize: in heavy snow, the cost of moving snow is around ¥80,000 per room a year, just under 10% of winter sales, split almost evenly across three items. Three directions follow from this structure. First, design for fewer call-outs. Because most of the cost scales with frequency, operational measures work directly—securing on-site snow storage space to reduce hauling, or running a smaller parking area in winter matched to guests’ actual needs. Second, if manual roof clearing is the premise, build in rising labor rates. A 30% rise in labor rates in heavy snow lifts the annual cost per room by about 10% to ¥86,700, while narrowing the gap with roof snow melting, so the next major renovation becomes a good time to consider snow guards, snow-load-resistant design, or a partial switch to snow melting.

Third, design to absorb the cost through rate. The median winter ADR across the 13 heavy-snow municipalities is ¥16,100, but in municipalities where snow itself is the product—Kutchan at ¥53,700 and Obanazawa (Ginzan Onsen) at ¥36,100—the share stays at a few percent. The cost of moving snow is set by snowfall, but its weight relative to sales is set by the rate. For properties that can build winter-only plans or snow-viewing experiences into their rates, ¥80,000 a year is a fully absorbable cost. Conversely, in locations where the rate is below ¥10,000, there is more room to rethink how winter is sold than to cut costs. As towns where winter ADR is 2.66 times summer show, snow can be a source of pricing power as well as a cost.

Frequently Asked Questions

Q. What is the basis for setting call-outs at “total snowfall depth ÷ 20 cm”?
A. Municipal road clearing and Sapporo City’s facility parking specification use about 10 cm of fresh snow as the call-out trigger, and Sapporo’s specification budgets 14 call-outs a year (about one per 34 cm). Lodging properties need to clear more often than public facilities to prepare for arrivals and departures every morning, so we set 20 cm as the base—between the two—and run the sensitivity analysis over a 15–30 cm range.

Q. Is the occupancy used in the winter sales denominator your own estimate?
A. No. It is an approximation that applies prefectural room occupancy for all facility types from the Japan Tourism Agency’s Overnight Travel Statistics Survey (average of January, February and December 2025) to each municipality. Municipal-level occupancy is not published, so we use prefectural values.

Q. Does roof snow melting pay off in heavy-snow areas?
A. Our estimates show it is hard to recover through savings on roof clearing alone. For the heavy-snow 60-room model, depreciation plus operating cost totals ¥4.46 million a year, versus ¥1.64 million for the manual roof clearing it replaces. The payback comes from how far it prevents closures for roof clearing and lost arrivals; protecting 4.6 days of winter sales a year makes it break even.
