Of the hotel building plans with 100 or more rooms in our database (63 plans, retrieved October 28, 2026), 16 plans totaling 3,672 rooms are scheduled for completion in 2027. Four of them (Osaka Dojimahama, Yokohama Kitanakadori, Nihonbashi 1-chome and Otemachi 2-chome) sit inside 39- to 63-story supertall mixed-use towers and account for 789 rooms; a single Makuhari plan with 1,000 rooms is the largest; and the remaining nine are standalone buildings whose filed use is hotel only (1,576 rooms in total).Of the 2027 plans, all 14 that have a recorded construction start date had reached their start dates by March 2026, so while completion years may slip, there is little chance that a large part of this supply will disappear.

This article lists the 16 plans and, for each site, sets out how much the new rooms add to the existing rooms within a 1 km radius (3 km for suburban and resort locations) and where the estimated settled ADR of the host ward or city (finalized September 2026 data) stands, in order to show where, and at what price tier, 2027 supply will pile up. It is written for operators weighing new openings, REITs and private funds considering acquisitions or developments, and regional banks underwriting loans.

By Completion Year, 2027 Is a Mid-Sized Cohort: 16 Plans and 3,672 Rooms

First, the distribution of all plans in the database. Stacked by scheduled completion year, the count is 21 plans / 5,254 rooms in 2025, 17 / 4,590 in 2026, 16 / 3,672 in 2027, 7 / 1,375 in 2028 and 2 / 200 in 2029 and later, thinning year by year in both plans and rooms. This downward slope, however, does not reflect slowing demand: permit applications are usually filed one to three years before completion, so later years naturally contain more plans that have not yet been filed. Given construction periods, 2027 is a year to which few new plans will still be added, making it the last cohort whose count is reasonably firm. Our article on later years,43 Hotel Projects Due for Completion in 2029 and Later, shows filings concentrated in Tokyo with mixed-use developments making up half; this article focuses on the year before, 2027.

Room counts per plan also differ. The 2027 cohort averages 230 rooms, slightly smaller than 2025 (250) and 2026 (270). Excluding Makuhari’s 1,000 rooms, it is 15 plans / 2,672 rooms, an average of 178, centered on central-city hotels of 100–270 rooms. A distinctive feature of hotels inside supertall mixed-use towers is that even though the buildings are large, the hotel components stay at 100–270 rooms, with most of the floor area taken up by residences and offices.

The 16 Plans Completing in 2027: From Rikuzentakata in February to Makuhari, Furano and Otemachi in December

Table 1 lists the 16 plans in order of scheduled completion. February brings 134 rooms in Rikuzentakata, Iwate (Kyoritsu Maintenance), 220 rooms at Osaka Dojimahama and 126 rooms at Sapporo Minami 7-jo Nishi 4; end of March, Shibuya Dogenzaka; April, Midori (Gunma), Sapporo Kita 6-jo Nishi 6 and Okayama Ekimae; May, Yokohama Kitanakadori; July, Kobe Onoedori; August, Higashi-Nippori and Uchikanda; September, Kyoto Shokokuji Monzen-cho; October, Nihonbashi 1-chome; and at the end of December, Makuhari, Furano and Otemachi. Regional core cities and Osaka come in the first half of the year, and central Tokyo and Chiba cluster in the second half.

Seven plans have names confirmed in published materials. For Nihonbashi 1-chome, Hilton’s corporate overview (updated August 25, 2026) lists Waldorf Astoria Tokyo Nihonbashi (197 rooms) as opening in 2027, and Yokohama Kitanakadori is included as Conrad Yokohama (272 rooms) among the 13 pipeline hotels in the same document. Osaka Dojimahama will be part of Mitsui Garden Hotels’ Premier series according to announcements by Mitsui Fudosan Residential and others; Okayama Ekimae, according toJR Shikoku’s announcement, will carry the company’s new brand “HOTEL NEMUS OKAYAMA by CLEMENT”;Kyoto Shokokuji Monzen-cho will be operated by Rosewood according to Kyoto City’s materials for its high-quality lodging attraction program; Shibuya Dogenzaka has been reported as TRUNK(HOTEL) DOGENZAKA (tentative name); and Dorchester Collection is reported to occupy about 110 rooms (planned) in TORCH TOWER at Otemachi 2-chome. For the remaining nine plans no brand could be confirmed in published materials, so only the building owner/developer and plan figures are shown.

Increase over Existing Rooms: 1–3% in Central Cities, Double Digits for Three Suburban Sites, Makuhari and Higashi-Nippori

Supply impact should be judged not by absolute room counts but as a ratio to the rooms already in each location. Table 2 and Figure 2 show the increase rate obtained by dividing planned rooms by the number of operating rooms within a 1 km radius of each site (3 km for the suburban/resort sites of Rikuzentakata, Midori and Furano, and for Kyoto Shokokuji Monzen-cho, which has only one operating property within 1 km).

The results split sharply in two. In central-city areas with existing stock of around 10,000 rooms — Sapporo Minami 7-jo Nishi 4 (+0.7%), Otemachi (+1.3%), Dojimahama and Sapporo Kita 6-jo Nishi 6 (+1.4%), Nihonbashi (+1.6%), Yokohama Kitanakadori (+2.7%), and Dogenzaka, Okayama, Kobe and Uchikanda (+3.1–3.4%) — a single new opening lifts catchment rooms by no more than around 3%. By contrast, in Midori, Gunma (150 rooms against 103 operating rooms within 3 km, +145.6%) and Rikuzentakata (134 against 98, +136.7%), a single opening more than doubles the catchment’s rooms. Makuhari Hibino has a sizable stock of 8 operating properties and 3,811 rooms within 1 km, but the 1,000-room plan equals +26.2%, the largest supply impact in the Tokyo metropolitan area. Higashi-Nippori (179 against 1,128 rooms within 1 km, +15.9%) and Furano (200 against 1,488 rooms within 3 km, +13.4%) follow.

Kyoto Shokokuji Monzen-cho needs care. Within 1 km there is only one operating property with 10+ rooms (12 rooms), so an increase rate on a 1 km basis is meaningless. Widening to 3 km gives 177 operating properties and 12,861 rooms, and the 135-room plan equals +1.0%. The numbers also show that the site, north of the Imperial Palace, is an “enclave” set apart from existing lodging clusters.

Four Mixed-Use Towers and Nine Standalone Hotels: Floor Area per Room Ranges from 16㎡ to 152㎡

Seven of the 16 plans are mixed-use, with filed uses other than hotel (residential, offices, retail, cinema, etc.). Four of these are supertall towers of 39 floors or more: Dojimahama (40 floors, hotel on floors 25–31), Yokohama Kitanakadori (40 floors, hotel on floors 1–16 with rental apartments above), Nihonbashi 1-chome (39 floors) and Otemachi 2-chome (63 floors, hotel on the upper floors, with opening reported for FY2028). Their hotel rooms total 789, or 21% of the 2027 cohort. The other three are Dogenzaka (11-floor hotel building), Okayama Ekimae (16-floor hotel building) and Makuhari (23 floors), totaling 1,307 rooms. For configurations like Dojimahama, Yokohama Kitanakadori and Okayama Ekimae, where the hotel sits in a building whose main floor area is residential, our articleResidential Mixed-Use Hotels: 7 Projects, 1,401 Rooms compares each project’s specifications with catchment data.

In mixed-use plans, the filed total floor area may cover the entire building (including residential and office components), so the efficiency of the hotel component alone cannot be compared. Floor area per room is therefore compared only for the nine standalone plans whose filed use is hotel (or hotel with parking) only.

Floor area per room across the nine standalone plans ranges from 16.4㎡ to 152.2㎡, a spread of about 9x. Uchikanda (16.4㎡), Sapporo Kita 6-jo Nishi 6 (16.7㎡), Midori (21.5㎡) and Higashi-Nippori (22.1㎡) stay around 20㎡ per room even including common areas, which reads as compact, high-density limited-service plans. The three plans at Uchikanda, Higashi-Nippori and Sapporo Kita 6-jo Nishi 6 (608 rooms) all have APA Group (APA Home / APA Mansion) as building owner, a clear sign of the group’s ability to stack high-density rooms on short construction schedules in high-demand locations in central Tokyo and north of Sapporo Station. Rikuzentakata (35.9㎡) and Kobe Onoedori (48.8㎡) fall in the business-to-midscale band, while Sapporo Minami 7-jo Nishi 4 (61.4㎡) and Furano (65.0㎡) suggest roomier rooms or a large share of common areas such as dining and bathing. Kyoto Shokokuji Monzen-cho’s 152.2㎡ comes from a low-rise, 3-floor plan with 20,553㎡ of floor area for 135 rooms, a level consistent with the announced luxury operation.

Estimated Settled ADR of Host Wards and Cities: Osaka Kita Ward −33.7%, Shibuya Ward and Okayama Kita Ward Up Double Digits

As the price level of the markets that will absorb this supply, Figure 4 sets the estimated settled ADR (finalized September 2026) of each site’s ward or city against the same month a year earlier. The highest is Shibuya Ward at ¥23,700 (N=33, +10.0% YoY), followed by Chuo Ward ¥17,300 (N=152, −2.4%), Chiba Mihama Ward ¥17,000 (N=13, +43.6%), Sapporo Chuo Ward ¥16,100 (N=140, +7.2%) and Kyoto Kamigyo Ward ¥15,400 (N=9, +6.2%). Chiyoda Ward is at ¥14,900 (N=80, −3.5%) and hosts two plans, Uchikanda and Otemachi.

Osaka Kita Ward stands in contrast. Its estimated settled ADR for September 2026 is ¥10,400 (N=74), down 33.7% from ¥15,600 a year earlier — the only steep decline among the 16 sites’ host wards and cities. 2025 coincided with Expo 2025 Osaka, Kansai; tracking Kita Ward’s monthly series, it fell from about ¥15,600 in September 2025 to about ¥8,800 in June 2026, then recovered to about ¥10,400 by September. Spring 2027, when Dojimahama’s 220 rooms open, will test whether the return to pre-Expo levels is progressing. Chiba Mihama Ward’s +43.6% is best read as a single September value rather than a trend, given its small base (N=13) and monthly swings driven by the Makuhari Messe event calendar (about ¥10,900 in July 2026 and about ¥17,000 in September).

For the three regional sites, the host city’s ADR is below ¥10,000. Okayama Kita Ward is rising at ¥8,600 (N=50, +12.9%), and the new 177-room hotel, integrated with the station-front redevelopment’s housing and retail, is in a location that can aim for a higher price tier. Rikuzentakata is at ¥7,900 (N=5, +26.8%), and Midori is reference-only (N=2), but both are markets with existing stock of around 100 rooms, where a new opening is large enough to rewrite the city’s ADR statistics themselves.

Three Lenses on 2027 Supply: Implications for Investors and Operators

Putting it together, 2027 supply consists of three layers: luxury/upper-upscale hotels inside central-city supertall towers, limited-service hotels in central cities and near stations, and large-scale entries into regional and suburban markets with thin existing stock. In the first layer, the four plans at Nihonbashi, Otemachi, Dojimahama and Yokohama Kitanakadori add only 1–3% to existing rooms while opening up the top end of the existing market. For REITs and private funds there is room to factor in spillover effects that raise the ADR ceiling for nearby existing assets; Chuo Ward, Chiyoda Ward and Yokohama Naka Ward in particular have a deep mid-priced tier with estimated settled ADR of ¥12,000–17,000, so new upper-tier hotels may widen upsell room for existing properties.

The second layer consists of limited-service hotels, typified by APA Group’s three plans (608 rooms) and the 223 rooms at Kobe Onoedori, with 1 km increase rates limited to 1.4–3.4%. For existing operators this means more competitors in the same price band, but estimated settled ADR in Chiyoda Ward, Sapporo Kita Ward and Kobe Chuo Ward is stable at −3.5% to +3.2% YoY, so the premise that resilient demand will absorb supply still holds. Higashi-Nippori (+15.9%) alone has a small catchment stock of 1,128 rooms, and with Arakawa Ward’s estimated settled ADR softening to ¥12,200 (N=11, −6.9%), it is a location where pricing around the opening deserves close watching.

The third layer is Makuhari’s 1,000 rooms, Furano’s 200, Midori’s 150 and Rikuzentakata’s 134. Makuhari adds +26.2% to 3,811 operating rooms within 1 km, Midori and Rikuzentakata more than double catchment rooms, and Furano adds +13.4%, so all of them are investments that “set the market” rather than “fit into the existing market.” For regional banks underwriting these projects, the host cities’ ADR statistics (N=2–13) do not reflect new supply on this scale, so rather than relying on existing averages, it is useful to build project-specific demand views grounded in each plan’s target guests and demand channels (Makuhari Messe events, Furano’s winter and summer resort demand, Midori’s industrial base) as a premise for underwriting. For Makuhari’s 1,000 rooms in particular, our analysisKaihin-Makuhari 1,000-Room ¥30bn Mixed-Use Development, which breaks down the conditions for viability from a product range derived from site conditions and Mihama Ward’s actual ADR, is a useful reference.

We can check the “market-setting” scale of the third layer from the occupancy side. Assuming 80% pre-opening occupancy in the catchment (a full-year baseline and a modeling assumption), and defining post-opening occupancy = 80% × (1 + demand growth) ÷ (1 + room growth), Table 5 varies demand growth across three scenarios (pessimistic ±0%, base +5%, optimistic +10%) plus +20% for each increase rate in Table 2. At a central-city +1.4%, occupancy holds at 78.9% even with flat demand — a drop of only about 1 point — and rises to 82.8% with +5% growth. Makuhari (+26.2%), by contrast, reaches only 69.7% even with +10% demand, and Rikuzentakata and Midori stay around 40% even with +20% demand; keeping catchment occupancy at pre-opening levels requires demand to grow at the same rate as rooms — in other words, the new hotels themselves must generate new demand.

Conclusion

Of the 63 hotel building plans with 100+ rooms in our database, 16 plans with 3,672 rooms complete in 2027. Four plans inside 39- to 63-story supertall mixed-use towers account for 789 rooms, one Makuhari plan for 1,000 rooms and nine standalone plans for 1,576 rooms; the increase over existing rooms is polarized, at +0.7–3.4% in central cities, +13–146% at three suburban/regional sites and +26.2% at Makuhari. Estimated settled ADR of the host wards and cities ranges from about ¥23,700 in Shibuya Ward to about ¥7,900 in Rikuzentakata, and Osaka Kita Ward continues its post-Expo adjustment at −33.7% YoY. Bearing in mind that the population covers plans in our database rather than every plan nationwide, and that completion years are as scheduled at the time of permit application and may slip, please use this as a map of 2027 supply.

Frequently Asked Questions

Q. Are these 16 plans all the hotel plans completing nationwide in 2027?

A. No. The figures cover plans scheduled for completion in 2027 among the building plans of 100+ rooms in our database (63 plans, retrieved October 28, 2026). Plans with fewer than 100 rooms and plans whose permit data have not yet been captured are not included.

Q. How is the increase over existing rooms calculated?

A. Planned rooms are divided by the rooms of properties within a 1 km radius of the site (3 km for suburban/resort sites and Kyoto Shokokuji Monzen-cho) that have 10+ rooms, excluding leisure hotels, and had sale prices confirmed on major booking sites in the most recent 3 months. Private vacation rentals and properties with fewer than 10 rooms are not included in the denominator.

Q. Is the ADR in this article the actual achieved rate?

A. It is an estimate: an estimated settled rate (tax-exclusive equivalent) obtained by applying a segment-specific adjustment factor to each property’s published lowest-plan level. Checked against property-level disclosures by listed hotel REITs, the median error is about 7%, and it differs from each property’s actual achieved rates and accounting figures.
