Business hotels in Niigata Prefecture ran at a high estimated OCC (based on OTA-listed inventory) of 88.8% on a monthly average in September 2026. Averaged by day of week, however, Thursday reached 93.1% against 82.0% for Sunday — a swing of more than 11pt within the week. Excluding the five days of the Silver Week holidays (September 19–23), the gap widens further: Thursday 93.1% vs Sunday 76.4%, a difference of 16.7pt. Hotels that sell out on Thursday are left with a quarter of their rooms empty on Sunday, and how to handle this trough is the key question for Niigata business hotels’ autumn–winter RevPAR. This article organizes September’s daily results by day of week, overlays the year-on-year change in estimated settled ADR and the November Thursday/Sunday booking curves, and then sets out a practical framework for creating Sunday-night demand.

Coverage: Niigata Prefecture business hotels, N=43–52 properties / 5,511–6,159 rooms (varies by day; based on listings on major booking sites). The price metric in this article is 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 October 29, 2026.

Estimated OCC by Day of Week — Thursday Is the Weekday Peak, Sunday the Weekly Trough

First, consider the simple average by day of week of the daily estimated OCC for all 30 days of September. On an all-days basis: Monday 88.6%, Tuesday 87.8%, Wednesday 85.3%, Thursday 93.1%, Friday 91.0%, Saturday 94.7% and Sunday 82.0% — a weekly shape of “Thursday–Saturday peak, Sunday trough.” Saturday’s top figure of 94.7% owes much to September 19 (Sat), the first day of Silver Week, which reached 98.7%; leisure demand temporarily spilled into weekday-oriented business hotels.

However, during the five holiday days (September 19–23), occupancy was driven by the holiday calendar rather than the character of the weekday, so these days are best excluded from day-of-week analysis. After exclusion the averages are Monday 85.2%, Tuesday 86.8%, Wednesday 89.1%, Thursday 93.1%, Friday 91.0%, Saturday 93.3% and Sunday 76.4% — making it clearer that Thursday is the weekday peak and Sunday the trough. The Thursday–Sunday gap is 16.7pt; applied to a cohort of 5,511–6,159 rooms, Sunday carries roughly 920–1,030 more vacant rooms than Thursday.

One point not to overlook: excluding the holidays, Wednesday rises from 85.3% to 89.1%. Because September 23 (Wed, Autumnal Equinox Day) fell to 69.9% — the second-lowest of the month — in the post-holiday lull, Wednesday looked like the weakest weekday on an all-days basis. With holidays removed, the typical weekly shape of a regional hub-city business hotel emerges: “Wednesday–Thursday as the core of business demand, Friday–Saturday a mix of leisure and business, Sunday empty.” For another prefecture where the Sunday trough was isolated from the same September results by excluding the five holiday days, see Miyagi Business Hotels in September: Thursday 95.2%, Sunday 86.4%.

Breaking Down the Four Sundays — 99.0% on the Holiday Sunday, 69–86% on Regular Sundays

The Sunday average of 82.0% combines four days of very different character. Broken down: September 6 at 85.9%, the 13th at 74.2%, the 20th (mid-holiday) at 99.0% and the 27th at 69.1% — a spread of nearly 30pt between the highest and lowest. The 20th, with Respect for the Aged Day on the 21st, fell in the middle of the holiday period; leisure and homecoming demand filled even weekday-oriented rooms, producing the month’s highest figure. The 27th, by contrast, was the lowest of the month, and the following day, the 28th (Mon), was slow to pick up at 80.0%.

Limited to the three regular Sundays, the range is 69.1–85.9% with an average of 76.4%, while the Thursdays of the same weeks (September 3, 10 and 24) ranged from 85.6% to 96.2%, averaging 92.0% (93.1% across all four Thursdays including September 17). In other words, the Sunday trough is not a one-off accident but a structural pattern repeating every week unless a holiday intervenes. The backdrop is the business-travel calendar: there is a certain volume of night-before stays ahead of Monday-morning appointments, but the mid-week multi-night business travelers and the Friday “straight from work to sightseeing” segment are absent on Sunday, so rooms never quite fill. Combined with the following Monday staying at 85.2% (excl.-holiday average), the 48 hours from Sunday to Monday are the softest inventory of the week for Niigata business hotels. The same consecutive Sunday–Monday dip has been observed in a neighboring prefecture; Toyama Business Hotels: Estimated OCC by Day of Week, Saturday 90.1% vs Sunday 73.9% explains how to read it.

Comparison with 9 Neighboring Prefectures — Niigata’s 16.7pt Thu–Sun Gap Is the 4th Largest

To see whether Niigata’s Sunday trough is a regional pattern or a depth specific to Niigata, we lined up eight neighboring prefectures in Hokuriku, southern Tohoku, Koshin and northern Kanto for the same September 2026 using the same procedure (business hotels; daily estimated OCC averaged by day of week; the five holiday days of September 19–23 excluded). The largest Thursday–Sunday gap is Yamagata’s 19.3pt, followed by Fukushima at 18.8pt and Gunma at 17.6pt; Niigata’s 16.7pt ranks 4th of the 9. By contrast, Miyagi (12.3pt) and Nagano (11.5pt) keep Sunday in the 80% range, with a shallow trough.

What sets Niigata apart is that while its Sunday level itself (76.4%) sits mid-pack among the nine, the following Monday also stays low at 85.2%, on par with Ishikawa. Toyama (91.1%), Miyagi (91.0%) and Yamagata (90.3%) recover to the 90% range on Monday even after a Sunday dip, whereas Niigata carries a gap to Thursday for two consecutive nights, Sunday and Monday. Thursday’s 93.1% is the next-highest after Miyagi (95.2%), Yamagata (94.8%) and Nagano (93.3%), so the high weekday peak also makes the trough stand out. This neighborhood comparison supports the article’s point that the “two nights of Sunday–Monday” need to be designed together rather than Sunday alone.

Estimated Settled ADR in Context — +12.6% YoY in September: Pricing Is Holding

Before discussing how to fill the occupancy trough, it is worth establishing where pricing stands. The estimated settled ADR of Niigata business hotels (tax-excluded equivalent, finalized monthly figures) was about ¥7,500 (¥7,462, N=126 properties) in September 2026, up 12.6% from about ¥6,600 (¥6,626, N=124 properties) a year earlier. August was also up 5.4% at about ¥8,400 (N=126) versus about ¥8,000 (N=127) the prior year. In 2026, January–June ran +1.9% to +10.8%, with only July at −1.1% — above the prior year in almost every month. With rates growing by double digits on top of a high monthly occupancy of 88.8%, September can be assessed as “a month that captured both high occupancy and revenue growth.”

This rate level serves as a yardstick for keeping Sunday measures from sliding into discounting. In a market capturing 93% on Thursday and 93% on Saturday, cutting prices sharply on Sunday alone to buy occupancy risks eroding the whole week’s average rate. Precisely because estimated settled ADR is growing by double digits year on year, there is room to treat Sunday vacancies not as “inventory to sell by lowering the price” but as “inventory to load with different demand.” Note that October–December estimated settled ADR figures are estimates based on current sales; simple comparisons with finalized figures should wait until each month closes.

November Thursday vs Sunday Booking Curves — The Trough Is Visible from 45 Days Out

So when does the Sunday trough start to show up in booking pace? We took three Thursday–Sunday pairs in November (6 days in total) and compared their booking curves from 45 days before the stay date to the latest observation (N=53 properties / 6,293 rooms). November 12 (Thu) built up from 52.8% at 45 days out to 66.8% at 18 days out, while November 15 (Sun) stayed at 48.4% at 45 days and 55.0% at 18 days — the gap widening from 4.4pt to 11.8pt. The November 5 (Thu) / 8 (Sun) pair was similar: nearly level at 45 days out (46.9% and 47.7%), but 68.1% vs 61.0% — a 7.1pt gap — by 11 days out.

Of particular interest is November 22 (Sun). With Labor Thanksgiving Day falling on the 23rd, this Sunday stood at 55.9% at 45 days out — the highest of the six days — and at 25 days out it was at 63.2%, 5.2pt above Thursday the 19th of the same week (58.0%). This is the same pattern as September 20 (Sun) reaching 99.0% mid-holiday: “a Sunday before a public holiday behaves like a Saturday” is reproduced in the November pace snapshot as well. Put differently, the Sunday trough can be identified in advance from the calendar, and the basic timeline design is this: for Sundays that are nearly level with Thursday at 45 days out, use different demand to fill the amount by which Thursday pulls ahead toward 30 days out and the final days. For a Niigata example tracking booking pace from 45 days out, Niigata October Long Weekend: Ryokan Saturday Fills First reads, on the same observation basis, how the remaining availability becomes skewed within a holiday weekend.

Fill Sunday with Price Cuts or with Different Demand? — A Break-even Estimate

Let us check with numbers the conclusion that “Sunday calls for different demand rather than price cuts.” When the Sunday rate is cut by x%, the estimated OCC needed to maintain Sunday room revenue is “current estimated OCC ÷ (1 − x).” Starting from the regular-Sunday average of 76.4%, a 10% cut requires 84.9% (+8.5pt), 15% requires 89.9% (+13.5pt) and 20% requires 95.5% (+19.1pt). With a 20% cut, revenue falls unless Sunday occupancy exceeds Thursday’s 93.1%. If a price cut recovers only about 5pt of occupancy (76.4% → 81.4%), Sunday revenue under a 10% cut declines by about 4.1%.

Required estimated OCC = starting estimated OCC ÷ (1 − price cut). Figures in parentheses are the required increase from the starting point. A simple estimate assuming the cut applies to all rooms sold on Sunday; price differences by channel or plan are not considered. Starting points are the September 2026 results in Table 2.

On the other hand, here is the uplift if part of the trough is filled with multi-night stays, night-before business stays and local demand while holding prices. Assuming a 100-room property selling at September’s estimated settled ADR (¥7,462, tax-excluded equivalent), filling just half of the trough (16.7pt) yields about 8.4 room-nights and about ¥62,300 per regular Sunday — or about ¥249,200 in room revenue per month in November, which has four regular Sundays (1st, 8th, 15th and 29th).

Starting point is the regular-Sunday average of 76.4%; the trough is the 16.7pt gap to the excl.-holiday Thursday of 93.1% (both September 2026 results). The rate applied is the September 2026 estimated settled ADR of Niigata business hotels, ¥7,462 (tax-excluded equivalent, N=126 properties), rounded to the nearest ¥100. Since the settled rate for a single Sunday may differ from the monthly average, substitute your own property’s Sunday rate. Source: MetroEngines Research; compiled by HotelBank Editorial Team

Side by side, the two tables show that filling Sunday through price cuts requires occupancy close to the weekday peak, whereas filling just a quarter to half of the trough with different demand while protecting price steadily adds revenue. In Niigata, where estimated settled ADR is running +12.6% YoY, focusing Sunday measures on product and booking-condition design rather than price avoids damaging the week’s overall rate.

Summary — Three Yardsticks for Niigata Business Hotels Looking at Sunday

To sum up, the weekly shape of Niigata business hotels can be grasped through three points. First, the 16.7pt gap between Thursday 93.1% and Sunday 76.4% (excl. holidays) is the market baseline, and your own day-of-week curve should be read against it. Second, since estimated settled ADR grew +12.6% YoY in September, Sunday is not inventory to fill with discounts but inventory to load with “reasons to stay” — multi-night stays, LOS controls, night-before business stays and local demand. Third, because a Sunday followed by a holiday behaves like a Saturday (September 20 at 99.0%; November 22 at 55.9% at 45 days out), separate these out by calendar first and concentrate measures from 30 days out on regular Sundays only. Precisely because the Sunday trough is a structure that repeats every week, an operation designed once should be reusable throughout autumn and winter.

Frequently Asked Questions

Q. On which days of the week are Niigata business hotels busiest, and on which are they emptiest?

In September 2026 estimated OCC (OTA-listed inventory basis, excluding the September 19–23 holidays), Thursday (93.1%) and Saturday (93.3%) are high and Sunday (76.4%) is the lowest. Monday also stays at 85.2%, making the two nights from Sunday to Monday the most likely to have vacancies in the week.

Q. Is the Sunday trough unique to Niigata?

Comparing 9 neighboring prefectures using the same procedure, Niigata’s Thursday–Sunday gap of 16.7pt ranks 4th after Yamagata (19.3pt), Fukushima (18.8pt) and Gunma (17.6pt), so it is a pattern common to the region. Niigata is distinctive, however, in its weak Monday recovery, with the trough lasting two nights.

Q. Should Sundays be filled with price cuts?

From a starting Sunday level of 76.4%, a 10% rate cut requires 84.9% estimated OCC and a 20% cut requires 95.5% just to maintain room revenue. In a market where estimated settled ADR is running +12.6% YoY, it is more rational to fill Sunday with non-price measures such as multi-night stays, night-before business stays and local demand.

Q. When does the Sunday trough start to appear in bookings?

Comparing November Thursdays and Sundays, there is almost no gap at 45 days out; for November 15 (Sun), the gap to the same-week Thursday widened from 4.4pt at 45 days out to 11.8pt at 18 days out. Around the 30-days-out mark is the time to deploy Sunday-specific measures.

Q. Should Sundays followed by a public holiday be treated the same way?

A Sunday before a holiday behaves much like a Saturday. September 20 (mid-holiday) reached 99.0%, and November 22 (the day before Labor Thanksgiving Day) stood at 55.9% at 45 days out, above the same-week Thursday. Separate these out by calendar first and run them with Saturday-level pricing and conditions.

About the Data

■ Data Sources

OTA published inventory and price data continuously tracked by MetroEngines Research. Estimated OCC by day of week: daily values for Niigata business hotels in September 2026 (30 days, N=43–52 properties). Neighboring comparison: Toyama, Ishikawa, Fukui, Yamagata, Fukushima, Miyagi, Nagano and Gunma under the same conditions. Estimated settled ADR: monthly values from January 2025 to December 2026 (October–December 2026 are estimates). Booking curves: six stay dates, November 5, 8, 12, 15, 19 and 22, 2026 (N=53 properties).

■ Estimation Assumptions

Table 6 uses “required estimated OCC = starting estimated OCC ÷ (1 − price cut)” and assumes the cut applies to all rooms sold on Sunday. Table 7 assumes a 100-room property starting from the regular-Sunday average of 76.4%, fills 25–100% of the 16.7pt gap to Thursday (93.1%) at unchanged prices, and multiplies by the September 2026 estimated settled ADR of ¥7,462 (tax-excluded equivalent). Regular Sundays are the four in November (1st, 8th, 15th and 29th).

■ Limitations and Caveats

Estimated OCC is based on the sell-through of OTA-listed inventory and reads higher than actual room occupancy because unlisted rooms are counted as sold. Day-of-week averages are simple averages of 3–5 days per weekday and are affected by single-day outliers (e.g., 69.9% on the September 23 holiday). Among the neighboring prefectures, Fukui and Yamagata cover only around 20 properties. Tables 6 and 7 are simple estimates that treat the rate–occupancy relationship as fixed; settled rates on individual Sundays and demand response to price cuts vary by property. Estimated settled ADR is a monthly average and does not cover rates by day of week.
