Taking a simple day-of-week average of estimated OCC (based on OTA-listed inventory) across the 61 nights from September 1 to October 31, 2026 for business hotels in Tochigi Prefecture (N=58–66 properties), Sunday nights came in at 72.5% — the lowest of the seven days and 16.5 points below the highest, Saturday nights, at 89.0%. Recalculating without the 6 nights tied to public holidays and long weekends pushes Sunday nights down to 66.6%, 18.4 points below the Monday–Thursday average of 85.0%. The averages had been hiding a split: Sundays in the middle of a long weekend fill into the 90s, while ordinary Sundays sink to the 60s or low 70s. This article uses booking curves to check when this “Sunday trough” forms and how much of it recovers close in, and ties the findings to practical levers such as consecutive-night stays, workations and corporate pre-arrival stays.

Coverage: Tochigi Prefecture business hotels, N=58–66 properties (4,833–5,657 rooms; based on listings on major booking sites). Price metrics in this article are estimated settled ADR (the settled price level estimated from OTA and other sales data, tax-excluded equivalent); occupancy is an estimate based on OTA-listed inventory. Definitions are at the end of the article. Data as of November 4, 2026.

Estimated OCC by Day of Week — Only Sunday Sinks Sharply; Thursday Leads the Weekdays

We start with the simple day-of-week averages across all 61 nights. Monday nights came in at 79.6%, Tuesday 85.4%, Wednesday 83.6%, Thursday 86.8%, Friday 82.8%, Saturday 89.0% and Sunday 72.5%. Among weekdays Thursday was highest, and Friday sat a notch below Tuesday–Thursday. Saturday, carried by leisure demand, and Tuesday and Thursday, with deep business-travel demand, topped 85% (Wednesday was 83.6% because it includes the Autumnal Equinox Day), while Sunday and Monday fell below 80%. The shape suggests that Tochigi business hotels build occupancy on two pillars: business trips on weekdays and leisure on weekends.

This simple average, however, includes September’s Silver Week (September 19–23) and the October Sports Day three-day weekend (October 10–12). The chart and table below therefore re-aggregate the data excluding the 6 nights on which the stay date itself was a public holiday or the following day was a holiday (September 20, 21, 22 and 23, and October 11 and 12).

Removing the holiday-related nights lowers Sunday from 72.5% to 66.6%, a drop of 5.9 points — the trough actually deepens. Monday barely moves (79.6% to 80.0%), and Wednesday rises to 86.5% once the 60.3% of Autumnal Equinox Day (September 23) drops out. After excluding holidays, all 6 Sunday nights fall within a range of 60.4% to 71.5%. This is not a case of a few unlucky low days: on an ordinary Sunday, roughly 30% of inventory structurally goes unsold.

The sold-out property share tells the same story. On Saturday nights 43.8% of properties, and on Thursday nights 32.5%, had no listed inventory visible, while on Sunday nights the share was just 13.3%. Saturday and Thursday are “nights when some properties sell out”; Sunday is “a night when almost every property still has rooms left.”

Holidays Change the Character of Sunday — 90%+ Mid-Holiday, 60s on the Night Before a Return to Work

Looking at the 6 excluded nights individually, the weakness of Sunday comes down not to “because it is Sunday” but to “because the next day is a workday.” September 20 (Sun), followed by a public holiday, reached 90.4%, and October 11 (Sun) reached 90.1% — nearly Saturday levels. Conversely, the final days of the long weekends, September 23 (Wed, Autumnal Equinox Day) at 60.3% and October 12 (Mon, Sports Day) at 68.6%, fell to the same level as ordinary Sundays (60.4%–71.5%) regardless of the day of the week.

The takeaway is that, for Tochigi business hotels, the “trough night” is not Sunday on the calendar but the last night of a holiday period. In a regular week that is Sunday; on a three-day weekend it is the night of the final day. When building an annual pricing and inventory calendar, classifying nights by whether the next day is a holiday or a workday — rather than by day of week — maps demand peaks and troughs more accurately. How the final night of the same October three-day weekend played out on the ryokan side is analyzed in detail in Tochigi Oct 3-Day Weekend: Ryokan Night 1 86.5% vs Final Night 64.9%.

The shape holds month by month. Monthly estimated OCC was 79.0% in September and 87.0% in October, and non-holiday Sunday nights were 62.4% in September (3 nights) and 70.7% in October (3 nights) — the lowest of the seven days in both months. That Sundays stayed around 70% even in October, when the overall monthly level was high, shows that Sunday inventory does not fill on its own even in peak season.

Comparing Neighboring Prefectures — An 18.4pt Trough Is Common Across Northern Kanto; Just 4.8pt in Tokyo

Is this trough unique to Tochigi? We lined up business hotels in surrounding prefectures using the same definition, the same period and the same exclusion rule (excluding the 6 holiday-related nights).

The gap versus Monday–Thursday nights is 22.0 points in Ibaraki, 17.9 points in Gunma and 18.0 points in Fukushima — on par with or larger than Tochigi’s 18.4 points. Saitama is 14.8 points and Tokyo 4.8 points, and Tokyo’s Sunday nights themselves are high at 89.3%. The Sunday trough is less a weakness specific to Tochigi than a shape common to the prefectures surrounding Tokyo. Put the other way, hotels in neighboring prefectures carry the same trough, so demand for extending a Saturday stay into Sunday, or for arriving the night before a Monday-morning appointment, can be contested across prefectural lines. When benchmarking your own Sunday nights, it is worth widening the comparison beyond the in-prefecture average to neighboring prefectures as well.

Sunday on the Booking Curve — Already 16 Points Behind at T-45, and the Late Pickup Never Catches Thursday

So when does the Sunday trough form? From regular October weeks, we overlaid the booking curves of two Sunday nights (October 18 and 25), a Thursday night (October 22) and a Saturday night (October 24), from 45 days before the stay date to the day before. All cover Tochigi Prefecture business hotels, N=62–63 properties (5,323–5,447 rooms; based on listings on major booking sites).

At 45 days out, the two Sunday nights were in the low 40s, Thursday was at 57.0% and Saturday at 54.2% — a gap of around 15 points was already in place. Over the 15 days to T-30, Sunday nights added only 2.4–4.2 points, roughly the same as Thursday’s 4.1 points, so the gap did not narrow. Sunday curves only begin to rise in earnest from T-14: October 18 added 19.1 points in the final two weeks, from 51.4% at T-14 to 70.5% the day before, and October 25 added 13.4 points, from 56.7% to 70.1%.

Even so, the total pickup from T-45 to the day before was +29.6 to +30.0 points for Sunday nights, short of Thursday’s +39.9 points and Saturday’s +35.5 points. In other words, the Sunday trough is not a “slow start that catches up at the end” pattern; it is a pattern in which a gap opened early is never fully closed by the late pickup. Relying solely on last-minute rate cuts tends to mean giving up rate at a stage when there is little room left to grow. Deepening Sunday demand calls for product design that generates bookings including Sunday from as early as T-45 to T-30.

Where November Sundays Stand Now — Strong Early in the Month, an October-Like Start at Month-End

Let us apply these yardsticks to upcoming November stay dates. This is a snapshot based on observations through November 3, 2026, covering Tochigi Prefecture business hotels, N=59 properties (5,221 rooms; based on listings on major booking sites). The figures reflect current sales and may change with future bookings and inventory adjustments.

The Sunday nights of November 8 and 15 started from the low 50s at T-45 — more than 10 points above the two October Sundays (low 40s). With autumn-foliage leisure demand overlapping, early-November Sundays are off to a better start than October. However, November 15 added only 6.8 points from 57.6% at T-30 to 64.4% at 12 days out, while the Thursday night of November 12 gained 16.3 points over the same span, from 61.1% to 77.4%, widening the gap. The Sunday-specific stall remains.

The night to watch is November 22 (Sun), followed by Labor Thanksgiving Day: at 61.3% at T-45 and 72.3% at 19 days out, it has already exceeded the level October Sundays reached on the day before. The pattern noted earlier — “when the next day is a holiday, Sunday behaves like Saturday” — is showing up ahead of time here as well. Conversely, November 29 (Sun), at 39.9% at T-45 and 42.6% at T-30, is off to almost the same start as the two October Sundays — back to an ordinary Sunday. Thursday, November 26 in the same week was also at 50.1% at T-30, below the 61.1% of Thursday, October 22, making month-end a period to consider additional demand stimulation for both weekdays and Sunday.

Estimated Settled ADR Up 5.1% YoY in October — Monthly Rate Levels Are Holding

As a premise for thinking about how to handle the day-of-week occupancy gap through pricing, we also check the level of monthly estimated settled ADR (tax-excluded equivalent). For Tochigi Prefecture business hotels (N=137 properties), finalized figures were about ¥6,600 in September 2026 (about ¥6,600 a year earlier, +0.2%) and about ¥7,200 in October (about ¥6,900 a year earlier, +5.1%). September was flat year on year and October was above, meaning October occupancy was secured without eroding rates.

Coverage: Tochigi Prefecture business hotels, N=133–140 properties (per month). Estimated settled ADR (tax-excluded equivalent); all figures from January 2025 to October 2026 are finalized. The covered population differs from that of the estimated OCC figures (N=58–66).

Because estimated settled ADR is finalized on a monthly basis, this article does not address day-of-week pricing. What we can say is that, while monthly rate levels have not fallen below the prior year, roughly 30% of Sunday inventory is left over every week. To fill the empty nights while protecting monthly rates, selling the stay that includes Sunday as a product is more consistent than cutting Sunday rates in isolation (for rate trends by property type, see Tochigi ADR Splits by Type: Business +1.6%, City −4.1%, Ryokan +6.8%).

How Far Must Occupancy Recover for a Sunday Rate Cut to Pay Off?

Let us test the “rather than cutting Sunday rates in isolation” judgment with numbers. Starting from the 66.6% estimated OCC of non-holiday Sunday nights (September–October 2026), we indexed how RevPAR moves under combinations of rate change and final occupancy (pre-cut 66.6% = 100).

RevPAR index = final OCC × (1 + rate change) ÷ 66.6 × 100. An arithmetic simulation assuming the same rate change applies to every room sold; covers room revenue only and excludes variable costs such as OTA commissions and cleaning. Shaded cells are index 100 or above. This does not forecast any increase in occupancy from rate cuts.

The final OCC needed to return to an index of 100 is 70.1% for −5%, 74.0% for −10%, 78.4% for −15% and 83.3% for −20%. Meanwhile, the highest of the 6 regular Sunday nights in September–October 2026 was 71.5%. In other words, within the observed range only a cut of up to −5% pays off; a cut of −10% or more assumes an occupancy level that no regular Sunday reached during this period. If rates are moved at all, keeping changes small and building incremental occupancy through products such as consecutive-night and pre-arrival stays is also the less strained approach numerically.

For Revenue Managers at Tochigi Business Hotels — Insights and an Action Plan to Fill the Sunday Trough

As concrete measures, there are three directions that fit Tochigi’s demand context. The first is a Saturday–Sunday consecutive-night plan: for leisure travelers heading to Nikko, Nasu or Kinugawa, attach added value such as breakfast, parking or late check-out to the second (Sunday) night, making the consecutive stay easier to choose without lowering the standalone Sunday rate. The second is a Sunday-start workation / extended-stay plan, designed around stays of several nights from a Sunday check-in into the weekdays, built on rooms with desks and longer usage hours. Locations easily reached by Shinkansen from the Tokyo metropolitan area suit travelers who move on Sunday evening and work on site from Monday. The third is corporate pre-arrival demand: offering corporate terms premised on a Sunday pre-arrival stay to companies with plants or offices in the prefecture, for Monday-morning meetings, training or on-site inspections. All three are designed to sell Sunday not as “the night that goes unsold” but as a night connected to the high-occupancy days on either side.

Every measure assumes that you judge by overlaying your own figures on the market yardstick. Properties already achieving Sunday nights above the market average should consider rolling out the factors that are already working to final nights of long weekends, rather than forcing in additional measures.

Summary — Three Yardsticks for Measuring the Sunday Trough

The September–October day-of-week estimated OCC of Tochigi business hotels yields the following three yardsticks.

The Sunday trough appears every regular week and is already taking shape at 45 days out. That is exactly why the approach called for is to fill it early with products that connect Saturday leisure demand and Monday business demand, not with last-minute rate cuts. The fact that Sundays followed by a holiday fill like Saturdays is also the flip side of a key point: Sunday demand is not “absent” — it is “constrained by the next day’s plans.” Loosening that constraint through consecutive-night, extended and pre-arrival stays is likely the key for Tochigi business hotels to turn Sunday inventory into revenue.

Frequently Asked Questions — Sunday Occupancy at Tochigi Business Hotels

Which night of the week has the lowest occupancy at Tochigi business hotels?

In September–October 2026, Sunday nights had the lowest estimated OCC (based on OTA-listed inventory; N=58–66 properties): 72.5% as a simple average across all 61 nights, and 66.6% after excluding the 6 holiday-related nights. That is 18.4 points below the Monday–Thursday average of 85.0%.

Is Sunday occupancy also low during long weekends?

Not when the next day is a holiday. September 20, 2026 reached 90.4% and October 11 reached 90.1%, on par with Saturday nights. By contrast, the final nights of the long weekends — September 23 at 60.3% and October 12 at 68.6% — show that the trough appears on the last night of a holiday rather than on Sunday as such.

When does the Sunday trough form?

In regular weeks of October 2026, the gap was already in place 45 days before the stay date: Sunday nights stood at 40.9% and 40.1% at T-45, versus 57.0% for Thursday. The pickup through the day before was also only about 30 points for Sundays, short of Thursday’s 39.9 points.

Is Tochigi’s Sunday trough deeper than in other prefectures?

Under the same definition and period (September–October 2026, excluding holiday-related nights), the gap versus Monday–Thursday nights was 18.4 points in Tochigi, compared with 22.0 points in Ibaraki, 17.9 points in Gunma, 14.8 points in Saitama and 4.8 points in Tokyo. The pattern is common across the Northern Kanto region and shallow in Tokyo.

Should Sundays be filled by cutting rates?

In our simulation, starting from the 66.6% estimated OCC of non-holiday Sunday nights (September–October 2026), a 10% rate cut would require occupancy to recover to 74.0% just to keep room revenue flat. The highest of the 6 regular Sunday nights in September–October 2026 was 71.5%, so building demand through products that include Sunday — such as consecutive-night or pre-arrival stays — is more consistent than a rate cut alone.

Is estimated OCC the same as actual occupancy?

No, the definitions differ. It is an estimate based on listed inventory, calculated from the number of rooms remaining on OTAs and total room count. Because rooms not listed on OTAs are counted as sold, it tends to run higher than actual room occupancy. It is best used to read differences between days of the week or points in time rather than absolute levels.
