Plenty of articles cover hotel opening schedules, yet almost none put a number on how many months it actually takes to get from groundbreaking to completion. Taking the 70 hotel projects with 50 or more guest rooms in the building-plan data tracked by MetroEngines Research (as of October 12, 2026) and measuring the construction period as the gap between the construction start date and the scheduled completion date, standalone buildings used solely as hotels came in at a median of 23.9 months, while mixed-use buildings that also house offices, retail or housing took 48.5 months — a two-fold gap driven by building type alone. This article breaks the construction period down by room-count band, floor-count band and gross-floor-area band, works backward from a 2029 opening to the latest viable construction start, and estimates, using a 100-room model, the carrying cost the developer bears for every month the construction period is extended.

The Big Picture — Median of 33 Months Across 59 Projects; Half of Standalone Buildings Finish Within Two Years

Let us start with the distribution. For the 59 projects where both the start date and the scheduled completion date are known, construction periods range widely from a minimum of 12.0 months to a maximum of 99.0 months, with a median of 33.0 months and an interquartile range of 22.9–48.8 months. Most of this spread is explained by building type — standalone versus mixed-use. Of the 33 standalone buildings, 18 (54.5%) fall within 12–23 months, and adding the 24–35-month band brings the share completed within three years to 76%. By contrast, only 1 of the 26 mixed-use buildings finishes in under 24 months; the most common band is 48–59 months (8 projects), and 6 take 60 months or more. For a different angle on which conditions determine the number of years from groundbreaking to completion, see Hotel Build Times: 2.80-Year Median, 1.96 Solo vs 4.00 Mixed-Use.

Cut by room-count band, the effect of size is surprisingly small. The median is 32.9 months for 100–199 rooms (N=25) and 35.9 months for 200+ rooms (N=29): doubling the room count changes the construction period by only three months. The 50–99-room band has just 5 projects with a median of 47.0 months, but this is because it includes small projects that ran long due to location or site conditions — such as a 55-room project in Gion, Kyoto (47 months) and a 60-room project in Fukushima City (99 months) — so it cannot be said that smaller means faster. Floor count and gross floor area have a more straightforward relationship with construction period. The median is 23.9 months for 10–14 floors, 39.0 months for 15–29 floors and 50.5 months for 30+ floors. By gross floor area, the period lengthens almost monotonically with each band, from 18.5 months for under 5,000㎡ to 47.5 months for 30,000㎡ and above.

As for the type of work, 46 of the 70 projects are new builds, 1 is a reconstruction, and the rest have no type recorded. The median for new builds alone is 31.0 months, nearly the same as the overall figure; since there is only one non-new-build sample, this article does not compare new builds with extensions or reconstructions.

Standalone 23.9 Months vs Mixed-Use 48.5 Months — Why Construction Takes Longer Relative to Room Count

This is the core test of this article. We examined the hypothesis that mixed-use buildings housing offices, shops or residences “take longer to build relative to the number of hotel rooms” by comparing projects within the same room-count band. In the 100–199-room band, standalone buildings take 20.9 months (N=15) versus 48.5 months for mixed-use (N=10); in the 200+ band, 23.9 months (N=14) versus 44.0 months (N=15). In both bands, mixed-use buildings require roughly twice the construction period. Converted to a per-100-room basis, standalone buildings take 12.5 months and mixed-use 22.4 months, meaning the time required to produce one hotel room is about 1.8 times longer in a mixed-use building.

Source: Compiled by MetroEngines Research & Consulting from MLIT “Statistical Survey on Building Dynamics” (50+ rooms, N=70 projects; construction period calculated for N=59; as of October 12, 2026)

The underlying reason is the scale of the building itself. Mixed-use buildings have a median of 208 rooms, not far from the 175 rooms of standalone buildings, but their median height is 26 floors (11.5 for standalone), and the gross floor area of the whole project divided by the number of rooms reaches a median of 183㎡ per room (49㎡ for standalone). In other words, the hotel is merely a tenant occupying part of a large building, and what determines the construction period is the volume of work on the entire building, including offices and housing. Looking at construction period per 10,000㎡ of floor area, the order reverses — 13.6 months for mixed-use versus 32.4 months for standalone — so it is more accurate to say that mixed-use construction is not slow per se; rather, from the hotel’s perspective, it is a structure in which the hotel “waits for a volume of construction unrelated to its own room count.”

That said, a gap remains even when building heights are aligned. Limited to 14 floors or fewer, standalone buildings take 22.9 months (N=27) versus 32.9 months for mixed-use (N=7) — a 10-month difference. Mixed-use projects are often integrated with urban redevelopment or land readjustment schemes, and one likely contributing factor is that in some of these cases the start date refers to the commencement of the entire scheme. When a hotel operator considers moving into a mixed-use building, estimating the construction period from the building’s total floor area and number of floors, rather than from its own room count, will be closer to reality.

Projects and Rooms by Scheduled Completion Year — Later Years Look Thinner Because Only Projects Already Under Way Are Counted

Next, we line up the 70 projects by scheduled completion year. 2025 is the largest with 22 projects and 5,304 rooms, followed by 2026 with 20 projects / 4,770 rooms, 2027 with 18 / 3,802 and 2028 with 8 / 1,428, plus one project each (100 rooms apiece) in 2029 and 2031. Of the 15,504 rooms in total, 31 projects with 5,946 rooms had not yet reached their scheduled completion date as of the survey date (October 12, 2026).

The nature of the dataset is essential to keep in mind here. Because the data is captured from building-plan filings, it in principle only includes projects whose construction start has been decided. Given that the median construction period is about two years for standalone buildings and about four years for mixed-use, many standalone buildings slated for completion in 2028 will start construction during 2026, and those completing in 2029 will start in 2027 — and they have not yet been filed. The low counts from 2028 onward therefore do not reflect a thinning supply; they simply reflect that “plans that have not yet broken ground cannot be counted.” Figures for later years are a lower bound for the pipeline confirmed today and must be read on the premise that they will inevitably build up as new projects start construction.

Source: Compiled by MetroEngines Research & Consulting from MLIT “Statistical Survey on Building Dynamics” (50+ rooms, N=70 projects; construction period calculated for N=59; as of October 12, 2026)

By building type, standalone buildings dominate the 2025 and 2026 completions with 15 projects each, while 2027 is evenly split at 9 standalone and 9 mixed-use, and the two projects in 2029 and 2031 are both large-scale mixed-use redevelopments in central Tokyo. It is only natural that mixed-use buildings, with their longer construction periods, complete later — put the other way, standalone buildings have yet to appear in the 2028-and-later columns.

33 Projects with 200+ Rooms, 10,748 Rooms — List of Scheduled Completion, Uses and Construction Periods

Let us look at the individual projects. Projects with 200 or more rooms number 33 with 10,748 rooms, accounting for 69.3% of the rooms across all 70 projects. The largest is a 1,000-room project in Hibino, Mihama Ward, Chiba City (scheduled completion December 2027, mixed-use with a cinema and bathing facility, 36-month construction period), followed by a 750-room project in Chidori, Urayasu City (February 2026, standalone, 32 months), a 605-room project in Higashi Ward, Sapporo (March 2025, 33 months), and a 500-room project in Hanazono, Kutchan Town (December 2025, a resort development including hotel condominiums and villas, 48 months). Standalone buildings developed by limited-service chains stand out for their short construction periods of 12–24 months, while office-integrated projects in central Tokyo run long at 44–55 months. The list shows that even within the same “200+ rooms” category, construction periods vary by a factor of nearly eight. The business structure and absorption capacity of the largest project, the 1,000-room plan in front of Kaihin-Makuhari Station, are broken down individually in Kaihin-Makuhari 1,000-Room ¥30bn Mixed-Use: Breakeven ADR ¥13,200.

Back-Scheduling Table — To Open in 2029, When Must You Break Ground and When Must Design Begin?

Once the distribution of construction periods is known, the latest viable construction start can be worked back from the target opening date. Here we set three target months in which openings tend to cluster — April (start of the fiscal year), July (before the summer holidays) and December (before the year-end and New Year holidays) — assume a three-month preparation period from completion to opening, and derive construction start deadlines from the median and upper-quartile (buffered) construction periods by building type and room band. The three-month preparation period is an estimate based on the fact that many projects in developers’ published development schedules show three to four months between completion and opening.

Source: Compiled by MetroEngines Research & Consulting from MLIT “Statistical Survey on Building Dynamics.” The three-month preparation period from completion to opening is an estimate. “*Must already be under way” marks combinations whose start deadline falls before the survey date (October 2026).

What this table shows is that, on a 2029-opening timeline, the options have already narrowed. For a standalone 100–199-room building, the median-basis start deadline is April–December 2027, within reach for a project whose design is already under way. A standalone 200+ room building can also make it with a January–September 2027 start. For mixed-use buildings, however, applying construction periods of 49 months (100–199 rooms) and 44 months (200+ rooms) puts the start deadline at August 2025–January 2026 even for a December 2029 opening, meaning the project must already be under construction even on a median basis. The reality this data shows is that mixed-use buildings opening in 2029 are not “projects yet to be planned” but only “projects already under construction.”

Before construction come design and permitting. Planning documents for public buildings include examples allowing 6–7 months for schematic design, 10 months for detailed design, and 3–4 months for contractor selection and the building confirmation application. The statutory review period for building confirmation is 35 days for large buildings, and for properties requiring a structural calculation conformity assessment, MLIT data reports an average in the 50-day range from acceptance of the preliminary consultation to issuance of the confirmation certificate (53.4 days for certificates issued in December 2017). For a private-sector hotel, a reasonable rule of thumb would be 3–6 months for schematic design, 6–10 months for detailed design and 2–4 months from the confirmation application to construction preparation — a total of one year to somewhat over a year and a half (this article’s estimate). Where demolition of an existing building is involved, there are cases assuming around three months for a mid-rise building, and depending on scale, six months or more may need to be added. To target an April 2029 opening with a standalone 100–199-room building, working back from the April 2027 start deadline means design must have begun between autumn 2025 and spring 2026, and sites requiring demolition must move a further 3–6 months earlier.

Revenue Implications — Each Additional Month of Construction Adds About ¥22.6 Million for 100 Rooms

The construction period also has a direct bearing on post-opening revenue. Here we assume a 100-room limited-service hotel and make a simple estimate of the additional carrying cost the developer bears when the construction period is extended by one month. The assumptions below are all set by this article. Gross floor area is 30㎡ per room (including common areas) for 3,000㎡; the construction unit cost is about ¥591,000/㎡ (about ¥1.95 million per tsubo), derived from 2024 accommodation-use buildings in MLIT’s “Statistics on Building Construction Starts” (nationwide; planned construction cost ¥1.0384 trillion ÷ floor area 1.756 million ㎡), giving a construction cost of about ¥1.77 billion. Land is set at about ¥710 million, equal to 40% of the construction cost; 70% of the total project cost of about ¥2.48 billion is debt-financed, at an interest rate of 3.25% per annum, the long-term prime rate level as revised in August 2026. Pre-opening staff are assumed at 15 people with monthly labor cost of ¥350,000 each, and post-opening performance is assumed at an ADR of ¥15,000, annual occupancy of 80% and a GOP margin of 35%.

Source: Estimated by MetroEngines Research & Consulting. Construction unit cost from MLIT “Statistics on Building Construction Starts” 2024; interest rate from Mizuho Bank’s long-term prime rate (revised August 2026); construction cost inflation from the Tokyo forecast in Turner & Townsend’s “Global Construction Market Intelligence” report (2026 edition). Other figures are this article’s assumptions.

In total, every one-month extension of the construction period adds about ¥22.6 million to the developer’s costs, or about ¥230,000 per room. The largest component is the deferred operating profit of about ¥12.6 million, which exceeds the direct outlay of about ¥10 million for interest and labor combined. In other words, a longer construction period bites less as “extra spending” and more as “profit that should have been coming in being pushed back.” Applying the roughly 25-month longer construction period of mixed-use buildings versus standalone ones to this model, the difference amounts to about ¥560 million; how the hotel side prices in the value of time when negotiating lease terms and opening dates for mixed-use tenancies will shape its returns.

This figure moves with the assumptions for post-opening rate and occupancy. Holding interest (about ¥4.7 million) and labor (about ¥5.3 million) fixed and varying only the deferred operating profit across combinations of ADR and annual occupancy, the monthly total ranges from about ¥18.8 million to ¥27.0 million. The higher the rate and occupancy of the location, the greater the value of one month of construction time.

Source: Estimated by MetroEngines Research & Consulting. Interest, pre-opening staff labor cost and the 35% GOP margin are held at the same assumptions as Table 6. Bold indicates the base case used in the text.

Distinct from an extended construction period is a delay to the construction start itself. Construction costs in Tokyo are forecast to rise 6% in 2026, so a one-month delay in starting would push the ¥1.77 billion construction cost up by about ¥8.9 million. A one-year delay would mean about ¥110 million, which comes on top of the interest on holding the land longer. Put the other way, bringing design and permitting forward to start construction earlier is also the most reliable way to lock in construction costs.

Summary — Putting Numbers on the Development Timeline

To sum up, a hotel’s construction period is determined less by room count than by whether it is standalone or mixed-use, how many floors it has and how large its gross floor area is. The median is 23.9 months for standalone buildings and 48.5 months for mixed-use, and even when limited to 14 floors or fewer, mixed-use takes 10 months longer. This gap shows up directly in the 2029 back-scheduling table: standalone buildings can still make it with a 2027 start, whereas mixed-use buildings must already be under construction even on a median basis. The decline in project counts for later completion years stems from the nature of the dataset, which can only capture projects that have already broken ground, and does not mean future supply is thinning.

There are three takeaways for developers and operators. First, estimate the construction period from the scale of the whole building, not from your own room count. Second, work back from the target opening date including the upstream phases — three to four months from completion to opening, one year to somewhat over a year and a half from design to construction start, and a further 3–6 months if demolition is needed — and lock in the timing for starting design early. Third, hold the value of one month of construction as a concrete figure — about ¥22.6 million for 100 rooms — and build it into negotiations over rent, completion dates and penalty terms. Although the building-plan data is not a complete census, simply putting numbers on the construction timeline moves the discussion of opening schedules one step earlier, from “when will it open” to “when must construction start.”
