About 70 minutes from Tokyo on the Hokuriku Shinkansen, two neighbouring towns on the same southern foothills of Mt. Asama are separated by a threefold step in room rates. According to MetroEngines Research & Consulting, the estimated settled ADR for August 2026 was ¥38,100 in Karuizawa, Nagano (52 properties in the estimate), versus ¥12,300 in Miyota, the town immediately to the west (5 properties). The two are 10 km apart in a straight line — about 20 minutes by car.

The first wall a resort developer hits is that land in Karuizawa simply does not come to market. So should you cross into the next town? This article first breaks down what the price gap is actually made of, then layers on the 2026 (Reiwa 8) prefectural land price survey, the land-use regulation documents published by Karuizawa Town itself, the property-type mix of new openings, and an investment model for a single-unit vacation rental — to pin down, in numbers, the conditions under which “moving outside the town” makes sense.

Summary — Rates 3.1x, Land 3.3x, but Construction Costs Are the Same

The conclusions first. One: the 3.1x rate gap between Karuizawa and Miyota (August 2026) is almost the same size as the 3.3x land price gap. But land typically accounts for only 30–40% of a lodging project’s investment, and construction costs are exactly the same in both towns. So the land cost gap does not widen to 3.3x at the level of total investment. In this article’s single-unit rental model, the total investment gap is just 1.21x — far smaller than the rate gap.

Two: in the numbers, “moving to the edge of the town” comes before “moving out of the town”. In the 2026 prefectural land price survey, benchmark sites in Karuizawa’s holiday-home districts range from ¥27,500/㎡ in the Shinano-Oiwake station area to ¥210,000/㎡ in the Karuizawa station area — a 7.6x spread that is wider than the one across the town line.

Three: supply has become entirely small-scale. Of the 67 new openings identified in Nagano Prefecture in 2026, 29 (43.3%) were vacation rentals, averaging 1.2 rooms. Only one 100-room-class project is registered in the prefecture’s pipeline on a building-permit basis. In a town where land is hard to get, investment has shifted fully from “building a hotel” to “setting up a single rental unit”.

The Real Price Gap — 3.1x in August, Narrowing to 2.5x on an Annual Average

Start with the seasonality of Karuizawa’s estimated settled ADR. As a summer retreat, its rates concentrate sharply in August: ¥38,100 in August 2026 versus ¥18,700 in off-peak March — less than half. Compared with August 2025 (¥37,000), August 2026 was up 3.1% YoY, so the peak level exceeded the prior year.

Next, set it alongside the surrounding municipalities. Adding Saku (home to Sakudaira Station on the Hokuriku Shinkansen), Komoro on the Shinano Railway line, and Ueda, the August 2026 results for the five municipalities are shown below.

One point investors can easily misread deserves attention up front. The ratio of listed price to estimated settled ADR stands out at 5.11x in Miyota alone. Karuizawa is 1.74x and Saku 2.21x, so Miyota’s figure is clearly of a different nature.

The reason is the population of properties. Estimated settled ADR is calculated only for properties whose type can be confirmed (business, city, resort, ryokan, capsule), so in Miyota just 5 of the 32 listed properties qualify. The listed price, by contrast, averages the public prices of all 32, so it reflects the high rates of the vacation rentals and cottages at the centre of the town’s listed inventory. In other words, “Miyota ¥12,300” is the level of the town’s conventional lodging, not of its vacation-rental-class stock. Indeed, on listed price Miyota is ¥63,100 against Karuizawa’s ¥66,400 — a difference of just 5%.

This asymmetry becomes decisive in the investment model later on. Whether you build a conventional lodging property or set up vacation-rental-class inventory can flip the verdict on moving to the next town.

Check the full-year level as well. On a 12-month average from September 2025 to August 2026, Karuizawa is ¥23,500 against Miyota’s ¥9,400 — a ratio of 2.5x, smaller than the 3.1x for August alone. Karuizawa’s rate advantage is concentrated in the peak season and shrinks when averaged over the year.

Land — 3.3x Across the Town Line, but the 7.6x Spread Within Karuizawa Is Larger

From the MLIT Real Estate Information Library, we extracted residential benchmark land prices from the 2026 (Reiwa 8) prefectural land price survey (reference date July 1, 2026). The median is ¥83,000/㎡ in Karuizawa (6 sites) and ¥25,250/㎡ in Miyota (2 sites) — a ratio of 3.29x, almost the same size as the 3.09x ratio of estimated settled ADR in August 2026.

The rate of change is what stands out. Karuizawa’s residential land rose from ¥59,250 in 2022 to ¥83,000 in 2026 — up 40.1% in four years — and the latest YoY rise of +14.28% shows acceleration. Yet Miyota was also up 14.0% YoY in 2026, jumping from +5.8% in 2025. Within the same Saku region, Komoro rose only 0.93% and Saku 1.38%, so what is rising is “Karuizawa and the land directly next to it”. The premise that “the next town is still cheap” is rapidly approaching its expiry date.

Even more important is the dispersion within the town. Ranking by price the four benchmark sites in the 2026 survey that sit in Karuizawa’s Category 1 Low-Rise Exclusive Residential Zone (holiday-home districts): ¥27,500/㎡ in the Shinano-Oiwake station area, ¥31,800/㎡ in the Naka-Karuizawa station area, ¥130,000/㎡ in the Karuizawa station area, and ¥210,000/㎡ for a large holiday-home district, also in the Karuizawa station area. The cheapest and priciest are 7.6x apart. Moving west within the town yields a 4.7x step (¥27,500 vs. ¥130,000) — larger than the 3.3x gained by crossing the town line. How far land price gaps track room rate gaps is a question the same framework can be applied to in other markets, such as Kitakyushu–Kokura versus Hakata.

Regulation — 20% FAR, a 10 m Height Cap, and Location Restrictions Due Within FY2026

Land price is not the only reason sites don’t come to market in Karuizawa. According to the town’s December 2025 document “On Land Use in Karuizawa” (軽井沢町の土地利用について), its city planning area covers 8,301 ha — 53.2% of the 15,603 ha administrative area — of which 6,288 ha is zoned. Only three zone types are designated: Category 1 Low-Rise Exclusive Residential, Category 1 Residential, and Neighbourhood Commercial — just 3 of the 13 zone types defined nationally.

On top of this, the town’s “Nature Conservation Guidelines” (自然保護対策要綱), established in 1972 (Showa 47), impose their own standards by district. The standards that bite most directly on lodging development are those for the Recreation District, which corresponds to the unzoned area.

The Recreation District caps the floor area ratio at 20%, so even a 1,000㎡ lot allows only 200㎡ of floor area. In addition, construction is in principle suspended in summer (July 25 – August 31), and healthy trees over 10 m tall in the road setback are in principle to be preserved — constraints that affect both the build schedule and design freedom. The “Other” section of the same guidelines states explicitly that minpaku (private lodging) facilities, capsule hotels and the like are not permitted anywhere in the town (as worded in the guidelines; simple lodging and vacation rentals licensed under the Hotel Business Act are handled under a separate framework). For anyone setting up a single-unit rental, this means a Hotel Business Act licence is a prerequisite in Karuizawa — an entry condition for the business scheme.

Moreover, regulation is currently being tightened. On March 18, 2025, the town issued its “Declaration to Protect Karuizawa’s Natural Environment and Landscape”, and it is reviewing regulations under a roadmap spanning FY2025–FY2027 (Reiwa 7–9). Two items bear directly on lodging:

The one point to read as an investment matter is that the window for building new hotels and ryokan in the Kyu-Karuizawa area now has a visible end date. The district is to be “the minimum necessary area, in consideration of the impact on landowners’ property rights”, covering areas that encompass building agreement and landscape resident agreement zones, so the whole town will not close at once. Even so, the direction is for new supply in the area that commands the highest rates to be institutionally restricted — which raises the scarcity value of existing properties while pushing new entrants out toward the town’s periphery.

On the map, properties are densely distributed along Route 18 from Karuizawa Station through Naka-Karuizawa to Shinano-Oiwake and across the holiday-home districts, while on the Miyota side they are only scattered around Miyota Station and the holiday-home areas at the foot of Mt. Asama. In Saku, properties with larger room counts cluster around Sakudaira Station — a clearly different character.

Supply — 43% of New Openings Are Vacation Rentals; Only One 100-Room-Class Project in the Prefecture’s Pipeline

We identified 67 new openings in Nagano Prefecture in 2026. By property type, vacation rentals were the largest category at 29 (43.3%), with an average of 1.2 rooms. Cottages followed with 9 (average 9.2 rooms) and resort hotels with 7 (average 48.6 rooms). The national picture is the same: of 1,576 new openings nationwide in 2026, 765 (48.5%) were vacation rentals. Nationally, vacation rentals are the largest category by number of properties but only a small share once measured by room count.

Matching against property-master addresses for Karuizawa and Miyota only, new openings in Karuizawa declined by count from 17 in 2023 (81 rooms in total) to 10 in 2024 (106 rooms) and 5 in 2025 (69 rooms). Miyota went from 5 in 2023 to 3 in 2024 and 3 in 2025. Note that the 2026 figure (2 in Karuizawa) is based on confirmed listings and is still being captured, so it will increase as further listings appear.

The future pipeline is thinner still. Querying planning data derived from MLIT’s Building Construction Dynamics Survey for Nagano Prefecture, only one project is registered — 159 rooms in Otari Village (scheduled for completion in December 2026) — and there is no large project on a building-permit basis in the Saku region. Note, however, that this is on a building-permit basis as of the survey date; counts and rooms are expected to rise as further applications are filed, so it should be treated as the lower bound of the confirmed pipeline at present.

The distribution of property size also confirms that investment in this area has become small-ticket. Among the 304 Karuizawa properties with a confirmed room count in the property master, the median is 9 rooms; only 20 (6.6%) have 51 or more rooms, and 56 (18.4%) have a single room. Among Miyota’s 42 properties, the median is 5 rooms and 13 (31.0%) have a single room.

Depth of Year-Round Demand — Karuizawa Is a Tourism Employment Hub With More Workers Than Residents

The other question in deciding whether to move to the next town is the underlying strength of year-round occupancy. Using MLIT National Land Numerical Information’s 250 m-mesh future population estimates and the MIC/METI Economic Census, we compared 2 km radii around three stations.

The numbers run against intuition. The resident population within 2 km of Karuizawa Station is 3,089 — a quarter of Miyota Station’s — yet it has 5,913 employees, more than Miyota Station’s 5,418. Employees per resident are 1.91 for Karuizawa, 0.45 for Miyota and 0.62 for Sakudaira. Karuizawa is a tourism employment hub with more people working there than living there, while Miyota is predominantly residential.

This matters directly for investment decisions. The hypothesis that “the next town can pick up year-round business demand” is hard to sustain for Miyota. If you select on depth of employment, the candidate is the Sakudaira Station area, the deepest in the region with 1,353 establishments and 13,324 employees. But Saku’s estimated settled ADR was ¥8,500 in August 2026 (N=14 properties) — the lowest — because the product skews toward limited-service hotels and rates don’t hold up. In this region, rates and the depth of business demand are a clear trade-off.

In terms of population direction, only Miyota is on the growth side. The 2040 estimate for the Miyota Station area is +3.4% vs. 2020, in contrast to -3.9% for Karuizawa Station and -1.4% for Sakudaira Station. The aged 65+ share also differs widely: 28.2% in Miyota against 37.4% in Karuizawa. Miyota has the edge in long-term settlement demand, but that is a housing story rather than a lodging one.

On the mesh map, Karuizawa Station’s resident population is concentrated in a narrow band of town area south of the station, while the holiday-home districts to the north and west are almost blank. Holiday homes are not counted as year-round residents, so the map mirrors Karuizawa’s structure exactly: a thin permanent population coexisting with deep lodging demand. Note that trying to substantiate year-round occupancy from resident population will always underestimate Karuizawa.

As for how tight supply and demand are, occupancy for Nagano Prefecture as a whole in August 2026 (estimated, based on OTA-listed inventory) was 92.5% (557 properties, 19,508 rooms), building up to near sell-out in the peak month. This is an estimate based on the take-up of inventory sold on OTAs and differs from the properties’ overall actual occupancy.

Projection — Can the Land Cost Difference Offset a 3x Rate Gap?

We now load the figures so far into a single-unit rental model. The premise is 120㎡ of floor area (36.3 tsubo), a two-storey timber building, and one building = one unit — the format now at the centre of new openings in Nagano Prefecture.

Construction cost is shown in two stages. Stage 1 is the 2025 actual timber cost of ¥1.382M per tsubo, based on MLIT’s Building Construction Starts Statistics. Hotel construction costs rose 41% in two years, from an all-structure average of ¥1.38M per tsubo in 2022 to ¥1.95M in 2024, and remained elevated in 2025 at an all-structure average of ¥1.952M. For Stage 2, allowing for about +5% per year over the two years to groundbreaking in light of that pace, the cost per tsubo becomes ¥1.528M and the construction cost rises from ¥50.2M to ¥55.5M.

The result is clear. Total investment differs by only 1.21x between A and C, while the market rate differs by 2.5x. Land in Miyota is ¥17M cheaper, but the building and ancillary costs of ¥69.4M are the same in both towns, so cheaper land lowers total investment by only 17%. Meanwhile, achievable rates fall by 60%. This asymmetry pushes the Miyota scenario’s yield below half that of outer Karuizawa.

Working backwards, the decision rule comes down to a single number. If Miyota can achieve 82.8% or more of the outer-Karuizawa rate, Miyota comes out ahead (total investment ratio 82.0 ÷ 99.1). Conventional lodging is observed at 40%, far below that bar. However, as shown earlier, on listed price Miyota is at 95% (¥63,100 vs. Karuizawa’s ¥66,400). In other words, if the project can be set up as vacation-rental-class inventory, Miyota may clear the threshold. This is the article’s fork in the road.

“If you are building conventional lodging, go to the edge of Karuizawa; if you are setting up vacation-rental-class stock, Miyota can also work” — the order of the site search comes down to that one sentence. The latter, however, depends on the premise that Miyota’s vacation rentals achieve rates comparable to Karuizawa’s. Listed prices are averages of public prices, not transaction prices, and with only 5 Miyota properties in the settled-rate estimate, this premise remains a hypothesis to be verified against actual on-the-ground performance.

IRR tells a different story. On the conservative assumption of flat land prices, A (outer Karuizawa) is 2.04%, B (near-station Karuizawa) 0.66% and C (Miyota) -2.34%. But assume land appreciates 5% a year, and B overtakes A at 4.19%. A near-station holiday-home site in Karuizawa is not an investment that pays off through operating yield but one that pays off through land appreciation — because land makes up 65% of the total investment. Karuizawa residential land in the 2026 survey rose 14.28% YoY, so recent performance is well above 5% a year. Still, extrapolating past appreciation into the future is also the most fragile part of any projection as a basis for investment decisions.

Varying the sensitivities does not change the ranking. A still secures 3.98% even in the pessimistic case of 40% occupancy (full-year) and ADR -10%, while B and C only reach around 3.3% in the optimistic case of 60% occupancy (full-year) and ADR +10%. The rate gap translates directly into a hierarchy of yields.

Investment Verdict and Risks

Finally, three things to check as next steps. First, ask the town’s Environment Division and Construction Division directly whether the site under consideration falls within the Special Use District or the Specified Use Restriction Area. Under the roadmap, the districts will move to public inspection within FY2026. Second, verify the transaction performance of vacation-rental-class stock on the ground. The Miyota scenario in this article rests on the observed gap between listed price and estimated settled ADR, and whether that gap is filled in practice could reverse the conclusion. Third, estimate water and sewer connection feasibility and site preparation costs individually for each site. Under a 20% FAR, 5 m setbacks and tree preservation, the building you can put up and the cost of site preparation vary widely even for plots of the same size.
