On May 14, 2026, Imperial Hotel, Ltd. (帝国ホテル) revised its “Medium- to Long-Term Management Plan 2036,” first published in 2022. The revision targets the start of demolition of the Imperial Hotel Tokyo Tower Wing around the end of FY2030, while disclosing that the rebuild periods for both the Tower Wing and the Main Building are “undecided at this time.” Under the original 2021 plan, the Tower Wing was to be rebuilt in FY2024–2030 and the Main Building in FY2031–2036, making this a prime example of a large central-Tokyo redevelopment whose timeline has shifted amid rising construction and labor costs. Rather than judging the merits of the decision, this article reads it as a question every developer and asset manager faces in the same environment: the economics of choosing to defer a rebuild. We estimate the present value of deferral across three variables — construction cost escalation, discount rate and maintenance capex — and then review the market and supply pipeline within 1km of Hibiya, where the existing asset continues to earn.

The room stock in this article covers lodging facilities with 10 or more rooms (excluding leisure/love hotels) within a 1,000m radius of Imperial Hotel Tokyo. “Operating” refers to properties with selling prices confirmed on major booking sites in the most recent 3 months (September–November 2026) (as of November 2, 2026, compiled by MetroEngines Research).

What Has Been Decided and What Remains Open — A Timeline of Disclosures

First, let us pin down the facts from primary sources. The Imperial Hotel rebuild began with a board resolution on March 25, 2021, and five timely disclosures have accumulated over the following five years. Some media summaries state that “the Main Building rebuild period has been set for FY2026–2030,” but the revised plan itself positions those five years as a “rebuild preparation period” and states that the rebuild period itself is undecided. Because wording differs across media reports, this article follows the company’s own disclosure documents.

Three structural points can be read from this timeline. First, the rebuild sequence has not changed. The framework — demolish the current Tower Wing, build a new tower jointly with Mitsui Fudosan, then rebuild the Main Building on the company’s own — is the same as in 2021; only the timeline has moved. Second, the delayed start is synchronized with NTT Hibiya Tower in the Central District (completion planned FY2031). If banquet halls and a lodging-focused hotel open first in the Central District and the Tower Wing closes only once that capacity is in operation, the drop in operating scale during the closure can be kept small. Third, “maximizing company-wide earning power and securing cash” is stated as the top priority for FY2026–2030, with quantitative targets of net sales of ¥62.0bn or more and EBITDA of ¥7.0bn or more (FY2027–2030). The deferral is disclosed not as a mere postponement but as a deliberately designed period of earning from existing assets and building up funds.

How Much Have Construction Costs Risen? — Lodging Building Costs Up 1.8x in 7 Years

We verify the construction cost increase behind the deferral using lodging-use buildings in the MLIT “Building Construction Starts Survey” (estimated construction cost ÷ floor area). Nationwide, the unit cost of lodging construction rose from ¥1.11 million/tsubo in 2017 to ¥1.95 million/tsubo in 2024 — an annualized increase of about 8.4%. For the three years from 2021 to 2024 alone it went from ¥1.25 million to ¥1.95 million, +57%; while this includes a mix effect from a higher share of luxury projects among starts, it is highly indicative of the cost levels faced by large central-city projects. Tokyo alone reached ¥2.01 million/tsubo in 2024 — about 25% above ¥1.61 million/tsubo in 2019 — although year-to-year swings are large because floor area started in 2021–2023 was thin at 66,000–89,000㎡ a year.

The increase is not limited to lodging. Turner & Townsend’s tall-buildings cost survey published in March 2026 noted that office construction costs in Tokyo have risen by up to 50% since 2020, the largest increase among the six cities surveyed. Annualized, that is roughly 8% — the same level as the lodging escalation implied by the construction starts statistics. The “surge in construction costs, labor costs and energy prices” cited in Imperial Hotel’s disclosures suggests that the plan had become hard to sustain with the project cost estimated in 2021 left unchanged, and the question shifted to one of timing: break ground now, or wait? The impact of rebuild-specific items such as demolition costs and floor-area loss from existing non-conforming status on per-room cost is covered separately in Hotel Demolition ¥51k–147k/m²: 30% FAR Loss Lifts Cost/Room 12%.

Breaking Down the Economics of Deferral — Cost Escalation, Discount Rate and Maintenance Capex

Under what conditions, then, does deferring a rebuild by several years make sense? Assuming the same site, we compare in present-value terms (A) breaking ground on the original schedule, and (B) deferring by 2–6 years while operating and maintaining the existing building. We do not estimate Imperial Hotel’s undisclosed financials; the only monetary benchmark is the ¥200bn lower bound of the total project cost the company published in 2021. All other variables are “assumptions of this article,” and the table below distinguishes published figures from assumptions.

The effect of deferral splits into three terms. The first is the change in the present value of construction cost: the nominal cost grows at rate g, but future outlays are discounted at rate r, so if g is below r, deferral shrinks the present value of construction cost, and if it is above, it inflates it. The second is the net income from continuing to operate the existing facility — operating cash flow minus maintenance capex. The third is the opportunity cost of pushing back the new facility’s earnings. The chart below overlays the nominal value of the first term with the boundary line at which present value stays flat under a 5% discount rate.

Summing the three terms and mechanically applying the ¥200bn project cost gives the net present value of deferral as follows. If construction costs rise 5% a year — equal to the discount rate — the first term is zero, and the earnings gap and maintenance burden become pure cost: −¥9.3bn for a 2-year deferral and −¥25.4bn for 6 years. If 8% escalation continues, a 6-year deferral reaches −¥62.2bn. Conversely, if escalation settles at 3% a year, the construction cost savings nearly offset the earnings gap, limiting a 6-year deferral to −¥3.6bn. If it slows to 2% a year, deferral turns positive, at +¥6.5bn over 6 years.

In summary, whether deferral pays essentially comes down to whether construction cost escalation falls below the discount rate minus the earnings gap (new facility 5% − existing 3% + maintenance 0.5% = 2.5%). In our base case, the breakeven escalation rate is 2.5–2.7% a year; raising the discount rate to 7% widens the tolerance to 4.6–4.8% a year, and narrowing the earnings gap to 1.5% widens it to 3.5–3.6% a year. In other words, the higher an entity’s cost of capital — and the more its existing facility is already earning — the greater the value of waiting.

This mechanical model leaves out three elements indicated in the disclosures. One is the value of continued operation: following the May 2024 change, some Tower Wing rooms and the banquet halls keep operating on an interim basis until demolition begins, so operating scale that would have been lost from FY2024 under the original plan is maintained until FY2030. Another is funding: simply adding up the FY2026–2030 EBITDA targets (¥5.9bn in FY2026 and ¥7.0bn+ in each of FY2027–2030) gives ¥33.9bn or more — targets, not results, but they show the period is designed to build up cash before construction starts. Finally, the revised plan’s citing of “the time required to develop a higher-quality business plan” amounts to an option value of time: it preserves the flexibility to revisit design and use mix while the construction cost outlook is hard to read. When it is unclear whether escalation will slow from 8% to the 4% range or accelerate again, not fixing the start date has value in itself.

The Market While the Existing Asset Earns — Chiyoda Ward ADR Topped ¥20,000 in April 2026

The second term of the deferral economics rests on the market environment while the existing facility keeps operating. According to MetroEngines Research data, Chiyoda Ward ADR (estimated settled ADR, area median) reached ¥20,300 in April 2026 (N=80 properties), up 7.0% YoY and above ¥20,000, forming the annual peak. In summer, however, August 2026 was ¥12,600 (N=80), down 10.9% YoY, and September ¥14,900 (N=80), down 3.5%, so some months fell below the prior year. Tokyo as a whole was ¥13,700 in September 2026 (N=1,139 properties), up only 1.9% YoY, suggesting a calmer phase after the strong rise seen in autumn 2025.

Narrowing to city hotels in Chiyoda Ward (N=12 properties), whose guest profile is close to that of a grand hotel, April 2026 ADR was ¥36,500, up 0.7% YoY, and September ¥24,400, down 0.7% — holding at prior-year levels. On occupancy, Tokyo’s occupancy rate (OTA-listed inventory basis, estimate) averaged a high 89.8% in September 2026 (805 properties / 104,583 rooms, based on major booking-site listings). This is an estimate based on sell-through of inventory sold on OTAs and differs from actual whole-property occupancy, but it indicates that central Tokyo rooms continue to fill easily. Imperial Hotel Tokyo’s listed price (all-plan average, tax included, two guests per room) ranged from a monthly average of ¥89,000 to ¥137,000 over the latest 12 months (October 2025–September 2026), with a 12-month average of about ¥114,000, confirming that the existing Main Building continues to operate in the high price band. The Ministry of Internal Affairs and Communications’ Consumer Price Index for accommodation (nationwide) stood at 172.1 in September 2026 (2020 = 100), up 5.7% YoY, a price environment that continues to support the earning power of existing assets.

Supply Within 1km of Hibiya — 11,103 Operating Rooms, 68% Opened Since 2010

When considering the rebuild timeline, it is also worth understanding how surrounding supply has built up. Within a 1km radius of Imperial Hotel Tokyo there are 63 operating lodging facilities with 10 or more rooms, totaling 11,103 rooms (as of November 2, 2026). Cumulative stock of properties with a confirmed opening year grew from 39 properties / 7,545 rooms in 2017 to 67 properties / 11,558 rooms in 2026, up 53% over 9 years; after 2,300 rooms were added in the three years to 2019, growth continued at roughly 100–400 rooms a year from 2020 onward. By opening decade, the 11,103 operating rooms break down into 26 properties / 4,356 rooms opened in the 2010s and 21 properties / 3,182 rooms opened in the 2020s — together, 68% are newer buildings opened in 2010 or later. Imperial Hotel Tokyo (570 rooms), opened in the 1890s, and Dai-ichi Hotel Tokyo (第一ホテル東京, 278 rooms), opened in the 1930s, are the two properties with the longest history in this area.

By category, business hotels are the largest group at 38 properties / 6,339 rooms, 57% of operating rooms, followed by city hotels at 11 properties / 2,108 rooms and deluxe hotels at 9 properties / 2,070 rooms. By size, large properties with 201+ rooms account for 25 properties / 7,031 rooms, or 63% of operating rooms, showing that this area consists of large, high-rise lodging facilities. The map below shows the distribution of the 63 operating properties; circle size represents room count and color represents category.

Planned additions to this area are concentrated in the Uchisaiwaicho 1-chome block itself. Under the schedule for “HIBIYA CROSSPARK,” the block name announced by NTT Urban Development and others in April 2026, the South District tower is to be completed in FY2028 and NTT Hibiya Tower in the Central District in FY2031. MLIT’s “Building Dynamics Statistics” also records two projects including lodging use: Uchisaiwaicho 1-chome 1-6 et al., Chiyoda Ward (46 floors, approx. 361,000㎡ total floor area, completion planned February 2029) and Uchisaiwaicho 1-1-1 (48 floors, approx. 361,000㎡, completion planned October 2031). According to Imperial Hotel’s revised plan, the upper floors of the Central District will house a small-luxury lodging-focused hotel under a new company brand, and the lower floors will include a grand banquet hall of over 1,000㎡ and a mid-size banquet hall of around 300㎡. Completion dates for the North District’s new tower (46 floors above ground, 4 below; rental housing, serviced apartments, offices, etc.) and the new Main Building (a standalone grand hotel) are undecided, so the area’s supply calendar beyond FY2031 is not yet fixed.

Location and Land Prices — Uchisaiwaicho Up 2.7% a Year, a Different Trajectory From Ginza’s +10.9%

How the value of a deferred site is moving is also part of the decision. In MLIT’s official land price publication, the benchmark site closest to Imperial Hotel Tokyo, “Chiyoda 5-46” (Uchisaiwaicho 1-2-1), was ¥15.4 million/㎡ as of January 1, 2026, up 2.7% YoY. Following +2.1% in 2024 and +3.4% in 2025, the past three years have seen moderate rises of 2–3% a year. “Chiyoda 5-25” (Yurakucho 1-1-3) on the Hibiya Station side was ¥22.0 million/㎡, +1.4%; “Chiyoda 5-12” on the Kasumigaseki side ¥16.1 million/㎡, +3.2%; and “Minato 5-1” on the Shimbashi Station side ¥15.1 million/㎡, +3.4% — land prices in the Uchisaiwaicho/Hibiya office district are within a range of stable growth. By contrast, Ginza’s “Chuo 5-22” (Ginza 4-5-6), at the eastern edge of the 1km radius, was ¥67.1 million/㎡, +10.9%, accelerating from +8.6% in 2025. Within the same area, land price momentum clearly diverges between commercial Ginza and business-district Uchisaiwaicho (for the required ADR that Ginza-side land prices impose on hotel projects, see Ginza Hotel Pipeline: 16 Sites, 107k m², Required ADR at ¥52.5M/m²).

On zoning, the Uchisaiwaicho 1-chome North Special Block (approx. 6.5ha) is divided into North, Central and South districts under Tokyo’s urban planning, with floor area ratios of 1,340% for the North District, 1,320% for the Central District and 1,340% for the South District (with special provisions where off-site infrastructure is provided), and height limits of 145m or 230m depending on the district. Conditions require lodging and similar uses to make up at least 2/10 of total floor area in the North District, 6/10 in the Central District and 4/10 in the South District; the approx. 1.2ha new Main Building site and approx. 1.1ha new tower site shown in Imperial Hotel’s 2021 disclosure fall within the North District. The Tower Wing site land price of approx. ¥59.7 million/tsubo (approx. ¥18.06 million/㎡) agreed with Mitsui Fudosan in 2021 was kept unchanged in 2023 as the basis for the expected transfer price of approx. ¥62bn for the 35% co-ownership interest. The disclosure explicitly states that “agreeing future transaction terms in advance avoids the risk of site price fluctuations” — a design worth noting, as it keeps the foundation of the funding plan stable even if the rebuild timing moves. Official land prices are not transaction prices themselves, and comparisons of levels remain subject to differences in use and lot conditions.

Implications for Developers and Asset Managers — Three Conditions Behind a Decision to “Wait”

Conclusion

For the Imperial Hotel Tokyo rebuild, the Tower Wing start has moved about 6 years later than in the original 2021 plan, and the Main Building’s timing is undecided. Assuming the lodging construction cost escalation shown by the construction starts statistics (8.4% a year over 2017–2024), deferral carries an opportunity cost on the order of billions to tens of billions of yen in our estimates; if escalation slows to the 2% range, it turns positive instead. What determines the value of deferral is the construction cost outlook itself. A design that uses FY2026–2030 as a preparation period to build cash from existing assets, bridges operations through Central District floor space and keeps flexibility over the start date may serve as a reference model for developers and asset managers facing the same environment. Within 1km of Hibiya, 11,103 operating rooms have accumulated, and HIBIYA CROSSPARK’s South and Central districts will be added in FY2028–2031. Until the timing of the North District’s new tower and new Main Building becomes clear, the area’s supply calendar beyond FY2031 will remain blank.

Frequently Asked Questions

Q. How long will the Imperial Hotel Tokyo Main Building stay open?
A. In the revised plan of May 14, 2026, the Main Building rebuild period is “undecided.” FY2026–2030 is positioned as the rebuild preparation period, and the current Main Building is planned to continue operating. The company has disclosed that it aims to start demolition of the Tower Wing around the end of FY2030.

Q. Are reports that “the Main Building rebuild has been set for FY2026–2030” correct?
A. The revised plan itself describes FY2026–2030 as the “Tower Wing reopening and Kyoto full-operation period (rebuild preparation period),” and states that the rebuild periods for both the Tower Wing and the Main Building are undecided. Because wording differs across media reports, this article follows the company’s disclosure documents.

Q. Are the estimates in this article Imperial Hotel’s actual planning figures?
A. No. The only published figure used is the ¥200bn lower bound of the 2021 total project cost estimate; construction cost escalation, discount rate, earning power and maintenance capex are all assumptions of this article. It is a mechanical model intended to illustrate the economics of deferral in general terms, not the company’s estimates or financial plans.
