ADR (Average Daily Rate) is the number that carries the “price” side of the three headline metrics used to measure hotel revenue. The formula itself is simple — room revenue ÷ rooms sold — but in practice three questions trip people up: what belongs in the numerator, how many rooms count in the denominator, and whether the price shown on an OTA can be called ADR at all. This article sets out the definition and worked examples, then uses MetroEngines Research’s estimated settled ADR to show actual market levels by hotel category and prefecture as of July 2026, quantifying exactly how far listed prices sit from settled rates.

Defining ADR — Room Revenue on Top, Rooms Actually Sold on the Bottom

ADR is room revenue over a given period divided by the number of rooms actually sold in that period. Framed against USALI (Uniform System of Accounts for the Lodging Industry), the international accounting standard, both the numerator and the denominator have clear boundaries.

In practice, the largest source of error here is how breakfast-inclusive plans are handled. A property that books the whole sale into the rooms department and a property that transfers the breakfast-equivalent amount to F&B will report different ADRs at the same selling price. Before comparing your ADR against another property or a REIT disclosure, confirm that the allocation rules match. Likewise, accommodation tax and bathing tax are amounts held on behalf of local authorities and never belong in room revenue.

Per-Room vs Per-Person — Why Japanese OTA Displays Cause Confusion

ADR is strictly a per-room rate. Yet listed prices on Japanese OTAs are usually shown as “double occupancy, per room, tax included,” and search screens sometimes divide that figure down to a per-person amount. Once a discussion proceeds with the units misaligned, ADR can easily end up off by a factor of two in either direction.

Whether one guest or two stays, ADR sees “one room,” and the difference in headcount is captured not by ADR but by a separate metric — guests per room (double occupancy). The familiar argument that a rising inbound share lifts double occupancy and therefore lets the same room command a higher rate only holds once ADR and double occupancy are looked at separately.

Worked Examples — One Night and One Month

Take a 100-room hotel and run the calculation both for a single day and for a full month. Because ADR covers only what was sold, the key point is that ADR itself does not fall when occupancy does.

The monthly ADR (¥16,000) does not match the single-day figure (¥15,000) because rates and rooms sold vary day by day within the month. Monthly ADR is not “the average of daily ADRs” but “monthly room revenue ÷ monthly rooms sold” — in other words, an average weighted by rooms sold. A month in which high-rate weekend dates sold heavily pushes ADR up; a month that sold mostly on weekdays pulls it down. Reporting a simple average of daily ADRs as the monthly ADR is a common mix-up in the field.

A Listed Price Is Not ADR — Settled Rates Run 34–57% of the Listed Average

The single most common misuse in market analysis is substituting “the price shown on an OTA” for ADR. Listed prices keep unsold high-rate plans on screen indefinitely, are quoted on a double-occupancy, tax-inclusive basis, and for meal-inclusive plans also carry the meal-equivalent amount. The all-plan average of listed prices therefore sits structurally above the settled rate.

MetroEngines Research multiplies each property’s lowest published OTA plan rate by a category-specific adjustment factor, calibrated against the per-property settled ADR that listed hotel REITs disclose, to produce an estimated settled ADR. The table below covers July 2026, taking properties with 30 rooms or more by category and lining up three stages: (1) the all-plan average listed price, (2) the lowest listed plan, and (3) estimated settled ADR.

Source: Compiled from MetroEngines Research by the HotelBank Editorial Team (July 2026). Columns 1, 2 and 3 are medians of each property’s monthly value. The rightmost column takes 3 ÷ 1 for each property and then the median of those ratios; it does not equal one median divided by another

For business hotels, the all-plan average listed price has a median of ¥16,600 against an estimated settled ADR of ¥9,400 — a per-property ratio with a median of 0.573. Treating the average listed price as ADR therefore overstates the level by more than 70%. City hotels come in at 0.492, resort hotels at 0.362 and ryokan at 0.340: the higher the category, the wider the gap.

That gap breaks into three stages. First, the drop from the all-plan average to the lowest plan: a per-property median of 0.645 for business hotels, falling to 0.524 for ryokan. A figure that averages everything from room-only to a two-meal suite does not represent the price band where volume actually sells. Second, the correction from the lowest plan to the settled rate: the category adjustment factor is 0.897 for business and city hotels and 0.607 for resorts and ryokan, and this single step absorbs both the consumption-tax basis difference and the real sales mix across higher-tier plans. Third, resorts and ryokan carry meal-equivalent amounts inside their listed prices far more often, so restating to a room-revenue ADR pulls the figure down further.

The practical implication is clear. Listed-price trends are useful for reading pricing behaviour, but carrying them straight into a revenue simulation or a comparison with REIT disclosures will put you an order of magnitude off. You need to switch explicitly between listed price and settled rate depending on the question.

Market Levels in July 2026 — By Category and by Prefecture

Next, the actual level of estimated settled ADR. For the single month of July 2026, the table below takes the category median for each of the 47 prefectures and summarises the distribution. Prefecture counts and property counts are the actual numbers in scope for estimation that month.

Source: Compiled from MetroEngines Research by the HotelBank Editorial Team (July 2026). Both listed price and estimated settled ADR are medians of prefecture medians. Prefectures with fewer than five properties in scope are excluded from the aggregation

Capsule hotels have a thin base — 76 properties nationwide in scope, spread across just seven prefectures. The ¥4,589 median should be treated as indicative and not used for prefecture-level comparison. The resort high (Ehime) also rests on eight properties and needs the same margin of interpretation.

Aggregating by prefecture across all categories, the national median estimated settled ADR for July 2026 was ¥8,974 (17,060 of 36,282 properties had an estimated settled ADR that could be calculated). The chart below shows the top 20 prefectures.

Source: Compiled from MetroEngines Research by the HotelBank Editorial Team (July 2026)

Top to bottom, the spread is roughly 2.2x. The point worth holding on to is that a higher rank does not imply a higher listed price. Tokyo ranks fourth on estimated settled ADR at ¥12,642, yet its all-plan average listed price of ¥22,650 is low among the leading prefectures. Hyogo runs the other way: a listed price of ¥34,879, among the highest in the country, against an estimated settled ADR of ¥12,027. The ratios are 0.558 for Tokyo and 0.345 for Hyogo — once the property mix differs, specifically the share of two-meal ryokan and resorts, the relationship between listed price and settled rate changes with it. A cross-prefecture comparison of listed prices cannot be restated as “ADR is higher in that prefecture.” Rates also diverge sharply between municipalities within a single prefecture, a distribution set out in Intra-Prefecture ADR Gaps 2026: Median 2.74x, Okinawa Widest at 5.86x.

How Far Can You Trust Estimated Settled ADR?

If you are going to use an estimate, you owe the reader an upfront statement of how far it can drift. The estimated settled ADR here sets its adjustment factors by matching against the actual per-property ADR that listed hotel REITs publish, and the residuals are then validated. Results by category segment are as follows.

Source: MetroEngines Research (validation period April–May 2026; matched against per-property published ADR from Invincible Investment Corporation; five-fold cross-validation repeated 20 times)

Note the unit carefully. 184 refers to property-months — property × month observations — not to a number of properties. The validation period covers just two months, April and May 2026, so the correct reading is roughly 90-odd properties matched across two months each. Restating this as “validated on 184 properties” would double the apparent coverage.

One more point: accuracy varies sharply by category. Business and city hotels show a median error of 6.0%, but resorts and ryokan sit at 15.8% on a thin validation sample of 34 property-months. This is because listed hotel REITs hold portfolios skewed toward limited-service properties — a constraint that comes from the composition of the matching set rather than from any limit of the estimation method. Estimated settled ADR for ryokan and resorts is therefore usable for relative comparison at prefecture or category level, but not for pinning down an individual property’s rate to a single digit of precision.

For a reference point on the actuals side: Invincible Investment Corporation reported monthly operating results for June 2026 across 103 domestic hotels showing occupancy of 82.2%, ADR of ¥12,306 and RevPAR of ¥10,118, with ADR down 5.0% and RevPAR down 6.0% year on year. That REIT’s holdings are concentrated in business and city hotels, and the reason it sits above this article’s national business-hotel median (estimated ¥7,159) is portfolio skew toward large urban assets. The national median describes the level of a “typical single property,” small regional operators included, and rests on a different population from a REIT portfolio average.

Screening Out Thin-Sample Months — The Case of Hyogo, November 2025

What gets overlooked most often when tracking ADR over time is month-to-month variation in the observation base. In a month where the number of properties in scope drops sharply, the mix of remaining properties skews, and the rate can spike away from reality.

Reviewing monthly series across 47 prefectures × 32 months from January 2024 to August 2026, exactly one month fell below 60% of that prefecture’s monthly median property count: Hyogo in November 2025.

Source: Compiled from MetroEngines Research by the HotelBank Editorial Team. Hyogo’s monthly median over the same period is 560 properties in scope

November 2025 had 34 properties in scope, just 6% of a normal month. That month’s estimated settled ADR of ¥17,611 sits ¥2,500–¥4,300 above the months either side, and the direction of the overshoot lines up with the collapse in the base. This article’s national series recalculates the median with that single point excluded. When working with a monthly ADR series, the safe practice is to check how many properties were observable that month before looking at the value itself.

Connecting ADR, OCC, RevPAR and GOP in a Single Chain

ADR on its own cannot describe revenue, because a rate increase that sacrifices occupancy still raises ADR. Linking ADR through to profit in one chain of equations makes clear which metric answers which layer of the question.

Source: Compiled by the HotelBank Editorial Team (amounts from the model case above)

Three working rules follow from this structure. First, whenever you discuss ADR month on month or year on year, always show OCC for the same period alongside it. If ADR is up while RevPAR is down, the story is demand, not pricing. Second, ADR carries no information about supply, so comparing properties with different room counts tells you nothing about the scale of revenue; to compare scale, work on a revenue basis by multiplying RevPAR by room count. Third, ADR is a rooms-department metric, and at ryokan and resorts with a high F&B share, optimising ADR alone may leave GOP unmoved.

Accommodation CPI Is Not ADR — Why a Statistical Index Cannot Set Your Rate Target

You sometimes hear the argument that “the accommodation price index is up X% year on year, so our ADR should be able to rise by the same amount.” But the accommodation component of the Consumer Price Index (CPI) published by the Ministry of Internal Affairs and Communications is built differently from ADR. The CPI is a fixed-basket price index covering accommodation charges nationwide, tax inclusive, not seasonally adjusted, and aggregated across hotels, ryokan and simple lodging alike. ADR, by contrast, is an actual result at the individual property level, tax exclusive, dividing that property’s room revenue by the rooms it actually sold.

Source: Compiled from MetroEngines Research by the HotelBank Editorial Team (median estimated settled ADR across 47 prefectures. Months in which properties in scope fell below 60% of that prefecture’s monthly median are excluded — one instance, Hyogo in November 2025)

Overlay the two charts and the seasonal peak in August is common to both. The amplitude is not. The CPI moved from 150.2 in January 2025 to 181.4 in August, +20.8%, while the national median estimated settled ADR moved from ¥8,960 to ¥11,407 over the same span, +27.3%. Because the index is designed to hold the base-year basket constant, it does not pick up the mix shift toward higher-rate categories during peak season nearly as fully as operators experience it.

On a year-on-year basis the difference is wider still. The accommodation CPI rose 5.9% in January 2026, 5.0% in March and 3.1% in June — broadly within a +3% to +6% band. The national median estimated settled ADR, meanwhile, was up 15.6% year on year in January 2026, up 9.5% in March, down 2.9% in June and down 5.6% in July: within a single year it swings from double-digit gains to outright declines.

Three factors drive the divergence. First, coverage: the CPI takes in accommodation charges nationwide including simple lodging and guesthouses, whereas the estimated settled ADR here has as its population those properties whose prices are observable on OTAs. Second, tax treatment: the CPI is tax inclusive, ADR is tax exclusive as a rule. Third, aggregation method: the CPI is an index using base-period weights, while ADR here is a median of prefecture medians, so shifts in property mix pass straight through.

The conclusion is that the accommodation CPI is a macro thermometer for which way accommodation prices are moving nationwide, not a metric from which to derive an individual property’s pricing target. To build your own ADR target, look at market levels in the same catchment and category and at your own demand curve. Conversely, when you need a medium-term price-growth assumption for a business plan, a broad index like the CPI swings less and is easier to work with. Use each for what it answers.

Frequently Asked Questions

Conclusion

ADR is room revenue divided by rooms sold — per room, excluding tax, covering only what was sold. The definition itself is simple, but because Japanese OTA displays are quoted on a “double occupancy, per room, tax included” basis, per-room and per-person rates are easily confused, and reading a listed price directly as ADR is a widespread misuse. Measured for July 2026, estimated settled ADR as a ratio of the all-plan average listed price had a property-level median of 0.573 for business hotels and 0.340 for ryokan — close to a twofold spread across categories.

On levels, the national median estimated settled ADR for July 2026 was ¥8,974; by category, ¥7,159 for business hotels, ¥9,131 for city hotels, ¥12,105 for ryokan and ¥14,180 for resort hotels. Across prefectures, the range runs about 2.2x from Okinawa at the top (¥13,722) to Tokushima at the bottom (¥6,346). All of these are estimates, however, and should be read with the median error of 7.5% — 15.8% for resorts and ryokan — in mind.

And ADR alone cannot describe revenue. Keep RevPAR = ADR × OCC always at hand: judge a rate increase on RevPAR, compare scale on room revenue, and judge profit on GOP. A statistical index like the accommodation CPI is useful for reading the direction of the overall market, but in the first half of 2026 the CPI ran at +3% to +6% year on year while the national median estimated settled ADR swung from +15.6% to −5.6% — the index cannot be restated as your own rate target. Every metric answers a different question, and using ADR correctly comes down to holding that line.
