In Nagano Prefecture’s accommodation market, estimated settled ADR through 2026 has traced an extreme shape: strong in winter, stalling in early summer. Line up the finalized months of January through August 2026 against the same months a year earlier and ryokan opened the year at +21.9% while resort hotels opened at +22.9% — double-digit growth for both — yet by June ryokan had slipped to -0.1% (¥11,556, N=501 properties) and resort hotels to -7.3% (¥13,558, N=112 properties), both below the prior year. July also came in below the prior year for both formats (ryokan -2.8% / resort hotels -2.5%), before a recovery in August to ryokan +1.1% and resort hotels +5.0%. In other words, 2026 in Nagano was not “a year when rates rose” but a year when only the peak months rose while shoulder-month pricing was left behind by the prior year. This article works through the finalized-month YoY figures, the occupancy structure behind June, and how to rebuild pricing ahead of the next low season.

Scope: ryokan and resort hotels in Nagano Prefecture (format classification follows our own category definitions). N for finalized months of estimated settled ADR = 485-551 ryokan / 111-137 resort hotels. The price metric used here is estimated settled ADR (the transacted price level estimated from OTA and other sales data, tax-exclusive equivalent); occupancy is an estimate based on OTA-listed inventory. Definitions for both appear at the end of this article. Data as of September 10, 2026.

Finalized Months, Year on Year — Double-Digit Growth to Start, Below Prior Year by June

First, some ground rules. The two formats covered here are ryokan and resort hotels as defined in our own category taxonomy. Nagano has a deep ryokan base (N=485-551 properties in finalized months); resort hotels are fewer in number (N=111-137) but larger in room count, and they carry the prefecture’s high-rate demand.

The table below shows year-on-year comparisons using finalized values only (historical-observation basis). Current and future months sit on a different basis and are excluded from this table entirely.

Taken as an eight-month total, ryokan were +6.7% and resort hotels +5.4% against the same period last year — genuinely positive for the first half of the year. But the monthly breakdown is anything but uniform. Double-digit growth in January-March accounts for almost all of the annual gain; from April the growth rate steps down month by month; resort hotels turn negative first in May; and in June both formats sink into the trough. Nagano is a market where winter demand readily pushes rates up, and in 2026 that winter momentum did not carry through to early summer.

Overlaying the two years reveals two things. First, the 2026 line runs clearly above 2025 from January through April, but touches or falls below the 2025 line from May through July. Second, the trough itself is deeper than it was a year earlier. Measured as the ratio of the highest to the lowest month across January-August, ryokan widened from 1.25x in 2025 (¥11,472-¥14,363) to 1.33x in 2026 (¥11,556-¥15,361), and resort hotels from 1.52x (¥13,590-¥20,636) to 1.60x (¥13,558-¥21,662). (Because 2026 has finalized values only through August, the prior year is aligned to the same January-August window.) The ceiling in peak months was successfully raised; the floor in shoulder months was held flat, or cut.

Is This Unique to Nagano? A Seven-Prefecture Ryokan Comparison

To test whether this shape is specific to Nagano, we lined up six neighbouring and structurally similar prefectures with deep ryokan bases on the same basis (estimated settled ADR, finalized months, year-on-year). The conclusion up front: “double-digit growth in winter, below prior year in June” is not a Nagano phenomenon but the shared 2026 shape of the ryokan market. All seven prefectures posted double-digit growth in January, and all seven fell below the prior year in June.

Source: MetroEngines Research; compiled by the HotelBank Editorial Team (estimated settled ADR, finalized months = historical basis, tax-exclusive equivalent. Jan-Aug total YoY is the ratio of the simple sums of each month’s finalized values)

That said, the depth of the decline differs markedly. June’s shortfall was deepest in Yamanashi at -11.0%, followed by Gifu at -4.7%, Gunma at -3.9% and Shizuoka at -3.6%. Nagano’s -0.1% was the shallowest of the seven, and its Jan-Aug total of +6.7% was the largest. Nagano, then, was not “a market that lost in the trough” but the market that held its footing best through a decline that hit the whole region. And since even here the gap between peak and trough months widened versus the prior year, the amplitude increase is likely to be larger still in the prefectures that fell further.

This comparison also gives you a baseline for judging your own property’s June. If your June came in at -5% year on year, that can be read as “substantially behind the Nagano market average (-0.1%)” or as “mid-pack within the ryokan market’s overall range (-0.1% to -11.0%)”. The choice of yardstick changes the response, so it is worth holding both the prefectural and the regional benchmark. For a closer look at how the split runs across formats, our analysis of the same June inflection in Kanagawa, broken out by city and business hotels can be read on the same basis.

What Was Happening in June — Occupancy Was Standing on Saturdays Alone

To understand why shoulder-month ADR failed to reach the prior year, look outside price. The metric from here is estimated OCC (based on OTA-listed inventory), a separate axis from the price metric. Prefecture-wide estimated OCC for June 2026 was 77.8% for ryokan (179-257 properties / 4,439-6,174 rooms, on a major-booking-site listing basis) and 79.3% for resort hotels (42-57 properties / 3,080-3,971 rooms). On level alone, that is hardly weak. Note that estimated OCC here is an estimate based on OTA-listed inventory and is defined differently from the room occupancy rate reported in Japan’s Accommodation Travel Statistics Survey.

Break it down by day of week, however, and it becomes clear what that average rests on. In June, ryokan averaged 75.7% Monday through Thursday against 87.3% on Saturday — a gap of 11.6pt. Resort hotels ran 75.8% Mon-Thu against 88.7% on Saturday, a gap of 12.9pt, wider still. The softest stay date in the prefecture was Tuesday, June 2, at 66.8% for ryokan and 65.4% for resort hotels.

August of the same year, by contrast, averaged 90.1% for ryokan (89.1% Mon-Thu / 93.9% Saturday = a 4.8pt gap) and 93.3% for resort hotels (92.6% / 94.9% = a 2.2pt gap). In August inventory was tight regardless of the day of week, leaving room to push rates up. In June, only the weekend wore the face of high season; weekdays were a different market altogether. Run a single monthly rate across that two-tier structure and you discount weekdays to fill them while leaving money on the table on Saturdays that would have sold anyway — and the month’s settled rate cannot beat the prior year.

Day-of-week differences in price are deliberately left out here. Estimated settled ADR is canonically a monthly aggregate and is not a metric that can express price levels at daily or day-of-week granularity. Day-of-week reading is confined to the occupancy axis.

Does Weekday Softness Fill In Late? The Recent Booking Curve

The assumption that “if weekdays are soft, they will fill closer in” can be tested against actual pickup. We compared the most recent observable booking curves for Nagano (from 45 days before the stay date to the present) for a representative weekday, Tuesday, October 6, 2026, and a representative weekend, Saturday, October 10. Our observation of holiday-period curves in Gifu over the five-day September break, using the same ryokan and resort mix, is a useful companion for placing your own property.

For ryokan, the October 6 (Tuesday) stay date sat at an estimated OCC of 68.1% at T-45 and built to 74.0% by T-27, a gain of +5.9pt. October 10 (Saturday) started at 83.9% at T-45 and reached 89.7% at T-31, a gain of +5.8pt. Resort hotels behave the same way: Tuesday moved 71.0% to 76.1% (+5.1pt), Saturday 76.8% to 82.5% (+5.7pt). The amount of pickup is near-identical, so the difference in starting position simply persists. Weekdays do not “surge late”; they carry the gap that was already open at T-45 (15.8pt for ryokan, 5.8pt for resort hotels) all the way to the stay date.

This shape carries a clear implication for shoulder-season pricing. Weekday softness is not the kind of problem last-minute discounting recovers; the outcome is largely settled by how the curve starts at T-45. Put the other way, whether your property’s estimated OCC at T-45 sits below the market level is a decision input you can act on far earlier than a rate cut. For how to separate the levers by lead time, the back-calculation framework of deciding at T-45, adjusting at T-30 and letting go at T-14 is a useful reference.

Where Current and Future Months Sit — Read Separately as Current-Basis Estimates

Everything so far has used finalized values only. For reference, here is estimated settled ADR for the current month onward. These sit on a different basis: estimates derived from current sales conditions, and they cannot simply be differenced against the prior year’s finalized values to produce a year-on-year figure. What follows is there to confirm “where the market sits given how it is selling now”; comparison with finalized values has to wait for month-end finalization.

Heading from autumn into winter, both formats are selling well above the finalized June level (ryokan ¥11,556 / resort hotels ¥13,558), and December for resort hotels is in the ¥21,742 band, level with finalized August (¥21,662). These figures will move with sales conditions, but at a minimum they confirm that Nagano’s structure — selling high in winter and midsummer — is intact as things stand. The problem, once again, is the other side of that structure: pricing in the trough months.

Conclusion — Three Yardsticks for Measuring Nagano’s Shoulder Months

In 2026, Nagano’s ryokan and resort hotels grew finalized winter ADR by double digits and then fell below the prior year in June and July. That asymmetry resolves into three yardsticks you can use when rebuilding pricing for the next low season.

Yardstick 1: read trough-month YoY on its own. Annual and half-year totals (ryokan +6.7%, resort hotels +5.4%) are pulled up by the peak months and hide the stall in the trough. The fact that finalized June was -0.1% for ryokan and -7.3% for resort hotels only becomes visible when the month is cut out on its own.

Yardstick 2: evaluate shoulder months split by day of week. June’s day-of-week gap was 11.6pt for ryokan and 12.9pt for resort hotels, more than double August’s (4.8pt / 2.2pt). Average occupancy in a shoulder month is merely the consequence of a strong Saturday; the monthly average alone cannot detect weekday softness.

Yardstick 3: treat the T-45 position as the decisive point. For both weekdays and weekends, pickup from T-45 to T-27 runs at roughly +5 to +6pt, so the initial gap does not close. Shoulder-season levers fit the structure better when weighted toward preparation ahead of that point rather than price moves close in.

Price a shoulder month with the same reflexes you use for a peak month and you discount weekdays too far while leaving Saturdays on the table. Nagano’s data for the first half of 2026 shows, in finalized values, how much that double loss takes out of the year’s growth.

Methodology and Sources

• Definition of estimated OCC (OTA-listed inventory basis): OTA-listed inventory occupancy = 100 – 100 x rooms remaining on OTA listings / total rooms. The sample is a fixed cohort of properties listing at least 30% of their total rooms on OTAs (the same property set for every stay date). It is an estimate based on how listed inventory is selling and is defined differently from actual room occupancy (it runs high because rooms not listed are counted as sold). The months covered here are June 2026 and August 2026, plus the stay dates of October 6 and October 10, 2026.
• Booking curve: based on observations from 45 days before the stay date through the present. The sample is 286 ryokan / 6,699 rooms in Nagano (October 6 stay) and 283 properties / 6,607 rooms (October 10 stay), plus 64 resort hotels / 4,251 rooms (October 6) and 63 properties / 4,241 rooms (October 10), all on a major-booking-site listing basis.
• Definition of estimated settled ADR: a transacted price level (tax-exclusive equivalent) estimated from OTA and other sales data (lowest-plan level x format-specific coefficient, ensembled across multiple channels). Past months are finalized values; current and future months are estimates based on current sales conditions. Cross-checked against published operating results, the median error is 6.6%. Year-on-year figures are calculated between finalized months only; estimates for current and future months are not used in any YoY calculation.
• Sample sizes: for estimated settled ADR, finalized months cover N=485-551 ryokan (January 2025 to August 2026) and N=111-137 resort hotels. Current and future months (September-December 2026) cover N=355-506 ryokan and N=102-122 resort hotels. For estimated OCC, June 2026 covers 179-257 ryokan / 4,439-6,174 rooms and 42-57 resort hotels / 3,080-3,971 rooms; August 2026 covers 186-257 ryokan / 4,563-6,050 rooms and 52-59 resort hotels / 3,632-4,090 rooms. Format classification follows our own category definitions of “ryokan” and “resort hotel”.

■ Data Sources

Estimated settled ADR, estimated OCC and booking curves are all aggregated from listed prices and inventory data collected by MetroEngines Research from major booking sites. Coverage spans ryokan and resort hotels in Nagano Prefecture and six comparison prefectures (Tochigi, Gunma, Niigata, Yamanashi, Gifu and Shizuoka), aggregated monthly for stay dates from January 2025 through December 2026. Finalized months use a historical basis (observed results for past months); current and future months are estimates based on current sales conditions. Data retrieved as of September 10, 2026.

■ Calculation Assumptions

Year-on-year figures are calculated between finalized months only; estimates for current and future months, which sit on a different basis, are excluded from any YoY calculation (Table 3). The January-August total YoY is the ratio of the simple sums of each month’s finalized estimated settled ADR, with no weighting by property count, occupancy or room scale. The highest-to-lowest month ratio is calculated over the same January-August window for both years, since 2026 has eight finalized months. For day-of-week estimated OCC, Monday to Thursday is treated as the weekday representative and Saturday as the weekend representative. The action plan in Table 4 sets out considerations that can be read from market aggregates and is not a guarantee of results.

■ Limitations and Caveats

Estimated settled ADR carries a median error of 6.6% when cross-checked against published operating results, so the monthly levels here are estimates with a comparable margin. Note that in months where the year-on-year change is within a few percentage points (ryokan June at -0.1%, for instance), the sign can flip within that estimation error. Estimated OCC reflects how OTA-listed inventory is selling, so it counts unlisted rooms as sold and runs above actual room occupancy. The property count N varies month to month (485-551 for ryokan), and turnover in the sample has a small effect on month-to-month comparison. This article also aggregates at the prefectural level, and within the same prefecture the shape of seasonal variation differs substantially by location (highland resort, hot-spring district, urban centre).
