A new-build hotel at 1-7-1 Honmachi, Chuo Ward, Osaka (13 floors above ground, 117 rooms), with Kasumigaseki Capital Co., Ltd. (霞ヶ関キャピタル) as the building owner, broke ground in December 2025 and, per its building plan, is scheduled for completion on August 31, 2028. In the list of planned development projects that the company published on August 25, 2026, it appears as the “Osaka Honmachi Hotel Project” with an opening in summer 2028, a gross floor area of 5,615㎡ and 117 rooms; neither the brand nor the operator has been disclosed. This article examines, in turn, the room stock in the trade area that will have to absorb these 117 rooms (102 operating properties with 17,584 rooms within a 1km radius of the site), Chuo Ward’s estimated transacted ADR, which has returned to its 2024 level now that the Expo period is over (¥10,578 in September 2026), and the demand base of a business district with 300,000 workers. It then estimates the benchmark rate against which the 2028 opening should be evaluated, and the required ADR.

Room stock in this article covers lodging properties with 10 or more rooms (excluding leisure/love hotels) within a 1,000m radius of the 1-7-1 Honmachi site. “Operating” refers to properties with sales prices confirmed on major booking sites in the most recent three months (August–October 2026) (as of October 28, 2026; compiled by MetroEngines Research). Identical properties listed under different names were deduplicated. MetroEngines Research tracks approx. 168,000 properties in Japan, of which approx. 27,000 properties / approx. 1.26 million rooms confirmed as operating on OTAs are analyzed.

Project Overview — Building Plan Data and the Owner’s Disclosure Agree: 117 Rooms, Summer 2028

First, let us confirm the outline of the project from two sources: building plan data and the building owner’s published materials. In building plan data compiled by MetroEngines Research & Consulting from the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) “Building Construction Dynamics Statistics Survey,” the project is listed at 1-7-1 Honmachi, Chuo Ward, Osaka City, Osaka Prefecture; principal use: hotel; new construction; 13 floors above ground; gross floor area 5,737.56㎡; 117 rooms; construction start December 1, 2025; scheduled completion August 31, 2028; building owner: Kasumigaseki Capital Co., Ltd. Meanwhile, the list of planned hotel development projects attached to Kasumigaseki Capital’s “Notice Regarding the Sale of Real Estate for Sale (Hotel Development Land),” published on August 25, 2026, includes No. 22, “Osaka Honmachi Hotel Project,” with an opening in summer 2028, a gross floor area of 5,615㎡ and 117 rooms. In the same list as of December 23, 2024, the project was only described as “in planning,” with no floor area or room count, which suggests the design was finalized and construction started over the past year and a half.

However, neither document states the brand name or the operator. The company operates multiple brands such as FAV and BASE LAYER, but which brand this project will open under has not been disclosed, and this article does not speculate. Dividing the 5,615㎡ gross floor area by 117 rooms gives about 48㎡ per room (including common areas), a somewhat more generous floor allocation than Hakata Ekiminami (3,229㎡ / 74 rooms, approx. 44㎡) or Nagoya Nishiki 3-chome (3,706㎡ / 110 rooms, approx. 34㎡) on the company’s list.

Location Assessment — Commercial Zone with 800% FAR; Official Land Prices Up by Double Digits for Three Straight Years

The site conditions can be confirmed in the layers of MLIT’s Real Estate Information Library. The zoning is a commercial zone with a floor area ratio (FAR) of 800% and a building coverage ratio of 80%, within an urbanization promotion area; building the 5,615㎡ gross floor area at the full FAR would require a site of only about 700㎡. As for land prices, the official land price point “Osaka Chuo 5-8” (1-12-1 Bingomachi), about 240m from the site, recorded ¥1.42 million/㎡ in 2024, ¥1.63 million/㎡ in 2025 and ¥1.88 million/㎡ in 2026 — double-digit increases for three consecutive years, with a 2026 YoY rise of +15.3%. The prefectural benchmark land price point “Chuo 5-5” about 430m away (1-12-3 Kitakyuhojimachi and others, as of July 1, 2026) shows the same trend at ¥1.54 million/㎡, +15.8%, indicating that commercial land prices across the Senba area are being pushed up by demand from both hotels and offices.

On the disaster side, the landform is classified as a sand bar / gravel bar, which falls into the “somewhat prone to liquefaction” category, and the site lies within the 0.5m-to-under-3m zone of Osaka Prefecture’s storm surge inundation assumption (published 2020). It is not within the flood inundation area (maximum assumed scale) or the tsunami inundation area, and it is not designated as a landslide warning area. These conditions are common to the low-lying Senba district and are within what a new commercial building can accommodate through the design of its foundations and mechanical floors. On transportation, daily passengers at Sakaisuji-Hommachi Station (Chuo Line) fell from 112,553 in FY2019 to 94,776 in FY2020 before recovering to 102,225 in FY2023, pointing to a recovery in business demand.

Trade-Area Demand Base — 19,068 Establishments and 300,000 Workers within 1km; Resident Population Rising to 2040

Honmachi is Osaka’s central business district. Within a 1km radius of the site there are 19,068 establishments and 300,558 workers, of whom 100,211 (33.3%) are office workers (Ministry of Internal Affairs and Communications / Ministry of Economy, Trade and Industry, “Economic Census for Business Activity,” 2021). These figures show the depth of weekday business demand and explain why the estimated OCC of Chuo Ward business hotels runs at 80–90% on September weekdays. The resident population is also substantial. Within a 1.5km radius it grew from 99,407 in 2020 to 109,578 in 2025, and the 2040 projection is 110,866 (+11.5% vs. 2020), indicating a continued return to the city center (MLIT National Land Numerical Information, future population projections by 250m mesh). In 2025, the working-age population accounted for 77.6% and those aged 65 and over for only 12.6%, a young profile for a neighborhood where offices and housing are mixed. Note that this resident population is the census-based usual resident population, not the daytime or transient population.

Room Stock Trends — From 8,751 to 18,645 Rooms within 1km in Nine Years; Gradual Additions of About 360 Rooms a Year Since 2020

What about the supply side? Within a 1km radius of the site (10+ rooms, excluding leisure hotels), 151 properties with 24,134 rooms were listed as of October 28, 2026. Of these, 104 properties with 17,920 rooms were operating, with sales prices confirmed on major booking sites in the last three months; deduplicating identical properties listed under different names gives 102 properties and 17,584 rooms. This article uses the deduplicated figure as the denominator for absorption capacity. Narrowing to a 500m radius gives 23 properties and 3,449 rooms, with 100–300-room business hotels densely lined up right next to the site.

Looking back year by year, the cumulative count of properties with a confirmed opening year jumped from 59 properties / 8,751 rooms in 2017 to 97 / 15,581 in 2019, then moved to 100 / 16,505 in 2020, 111 / 18,199 in 2023 and 115 / 18,645 in 2026 (excluding 7 properties / 520 rooms with no confirmed opening year). The net increase over nine years was 9,894 rooms, about 1,100 a year on average, but most of it was concentrated in the three years 2017–2019 (+6,830 rooms); in the six years since 2020, additions averaged only about 360 rooms a year. In other words, supply in Senba and Honmachi is in a phase of “gradual replenishment after a rapid build-up,” and 117 rooms equal one-third of the average annual addition since 2020 and 0.7% of the total stock.

By category, business hotels account for 76 properties and 13,621 rooms, or 77% of rooms, followed by city hotels (9 properties, 2,132 rooms) and deluxe hotels (5 properties, 1,098 rooms). By size class, 101–200 rooms is the largest group with 47 properties, and this 117-room project falls squarely in the middle of it. While the project will compete on the same footing as the existing stock in terms of scale, the question for 2028 will be which guest segment its design difference — relatively generous floor area per room — is packaged for.

Let us also check recent new supply. Within 1km, a large 503-room business hotel (Minamihonmachi 4-chome) opened in September 2025, and in April 2026 a 256-room lifestyle brand was added on the Shinsaibashi side through the rebranding of an existing hotel. On December 18, 2026, a 202-room railway-affiliated brand hotel directly connected to Hommachi Station on the Midosuji Line is scheduled to open, about 600m from the site. Just outside the 1km radius, a 223-room hotel directly connected to Shinsaibashi Station (Minamisenba 3-chome) opened on June 15, 2026, and the Osaka Nipponbashi Hotel Project on the building owner’s list (54 rooms, autumn 2027) is also coming in Chuo Ward.

Taken together, the 202 rooms in December 2026 and 117 rooms in summer 2028 would raise the operating stock within 1km from 17,584 to 17,903 rooms, +1.8%. Against the trade area’s track record of absorbing +6,830 rooms (+78%) in the three years 2017–2019, +319 rooms over two years is small. However, building plan data is a lower bound based on confirmation applications, and it should be read on the assumption that the numbers will grow as plans are added from 2027 onward. How the supply pipeline for Osaka City as a whole, including the Yumeshima IR, builds up through 2030 is laid out in Osaka’s 167,000 rooms and +2,500 from the Yumeshima IR — the 2027–2030 supply pipeline.

Rates and Occupancy — Chuo Ward’s Estimated Transacted ADR Fell from ¥16,000 During the Expo to ¥10,600; −1.8% vs. Two Years Earlier Signals Normalization

Next, let us confirm the rate that serves as the benchmark for evaluating the 2028 opening. Chuo Ward’s estimated transacted ADR (median of covered properties) was ¥10,773 in September 2024 (N=190), ¥16,018 in September 2025 during the Expo (N=188) and ¥10,578 in September 2026 (N=193). That is −34.0% YoY, but only −1.8% versus two years earlier, so it is most accurately read as a return to the pre-Expo level. Business hotels alone follow the same shape at ¥10,786 → ¥16,144 → ¥10,578 (N=155); Kita Ward went ¥9,593 → ¥15,629 → ¥10,360 (N=74), +8.0% vs. two years earlier, and Osaka Prefecture as a whole went ¥9,030 → ¥13,764 → ¥9,310 (N=655), +3.1%. All converge on the same normalization pattern: “back to the pre-Expo level, with Kita Ward and the prefecture slightly above it.” The pattern in which Shinsaibashi rates fell 36% YoY as a post-Expo rebound is also confirmed in New openings do not lower ADR — Kure up 6.5% despite +21% supply, Shinsaibashi −36% as a post-Expo rebound (four markets, summer 2026).

The monthly shape also supports normalization. In 2026, Chuo Ward tracked the same levels as 2024 through spring — ¥11,250 in January and ¥12,853 in April — fell to ¥9,290 in June, then recovered step by step through summer into autumn: ¥9,791 in July, ¥10,292 in August and ¥10,578 in September. October stands at ¥12,729 (N=189) based on listed levels as of the survey date, an upturn typical of the autumn demand season, but it is a pre-finalization estimate and should be viewed as subject to change. For reference, the accommodation charges component of the MIC “Consumer Price Index” (nationwide, 2020=100) was 172.1 in September 2026, 5.6% above 162.9 in September 2025, so accommodation prices nationwide continue to step up. Against that backdrop, the fact that central Osaka has returned to its pre-Expo level can also be read as “room left for upside” when considering 2028 rates.

What about occupancy? The estimated OCC of Chuo Ward business hotels (based on OTA listed inventory; estimate) averaged 82.3% for September 2026 (100 properties / 16,317 rooms, based on major booking site listings; 99–103 properties per day), 82.9% for all categories (130 properties / 19,720 rooms) and 86.1% for city hotels (11 properties / 2,397 rooms). By day, Tuesday through Thursday ran at roughly 80–90% (74–92%), while Sundays formed a trough of 67.9% (September 6) to 71.2%. The September 19–22 holiday weekend reached near-full levels at 94.8% → 100% → 99.1% → 90.3% — an occupancy shape typical of a central business district, where weekend and holiday leisure demand layers on top of weekday business demand.

Let us also look at how bookings build up. For Chuo Ward business hotels in September, the remaining-room ratio was 60.9% (occupancy 39.1%) 45 days before the stay date, 53.5% at 30 days, 41.5% at 14 days, 34.6% at 7 days and 17.7% the day before — about 24 points filled in the final two weeks. On weekdays (September 9 and 16), the remaining-room ratio went from 63–65% at 45 days out to 13–17% the day before, while September 19, the first day of the holiday weekend, was already down to 41.2% at 45 days out and finished at 5.2% the day before. In other words, there is a two-tier structure in which business demand consists mainly of short-lead bookings, while holidays fill early; a new 117-room property will also need pricing operations geared to capturing last-minute demand on weekdays.

Positioning — Median Estimated Transacted ADR of 87 Properties within 1km Is ¥9,056; Top 10% Exceed ¥17,000

Breaking rates down to individual properties reveals where the project stands. For the 87 operating properties within 1km for which an estimated transacted ADR can be calculated, the July–September 2026 average gives a median of ¥9,056, a bottom quartile of ¥7,697, a top quartile of ¥12,877 and a top decile of ¥16,889; the highest was ¥28,981 (a 107-room city hotel). The room-weighted average is ¥10,661, and because many large 300–900-room business hotels cluster around ¥7,000–10,000, the center of gravity of the stock lies in this band. On the other hand, among 100–200-room properties, city and lifestyle hotels that opened in 2019–2022 sit in the ¥18,000–24,000 band, showing that this is a market where product design can more than double rates even among properties of similar size.

For reference, there are six properties held by J-REITs within the same 1km radius. According to our ownership master (as of October 26, 2026; domestic only), Invincible Investment Corporation (インヴィンシブル投資法人) holds three properties (Sakaisuji-Honmachi, 190 rooms, ¥2,514 million; Otemae, 98 rooms, ¥1,192 million; Midosuji Hommachi, 108 rooms, ¥5,039 million), Hoshino Resorts REIT (星野リゾート・リート投資法人) holds one (103 rooms, ¥4,238 million, acquired April 2018), Ichigo Hotel REIT (いちごホテルリート投資法人) holds one (130 rooms, ¥1,630 million, acquired November 2015), and Japan Hotel REIT (ジャパン・ホテル・リート投資法人) holds one (124 rooms, ¥2,738 million; this REIT does not disclose property-level acquisition dates in its portfolio list). Dividing acquisition price by room count gives a range of ¥12–47 million per room, with the two properties acquired in 2018 high at ¥41–47 million. Setting this project’s total investment at ¥46 million per room in the next section’s estimate is consistent with recent acquisition levels in this area.

Required ADR Estimate — Construction at ¥2.18M per Tsubo and Land at Official Prices Give a ¥5.4bn Total Investment, or ¥46M per Room

Finally, we run a simple estimate of the rate that will be required when the hotel opens in 2028. All assumptions are drawn from public information. The 5,615㎡ gross floor area equals 1,699 tsubo; applying a construction cost of ¥2.178 million per tsubo — derived from the estimated construction cost for “hotels or ryokan” nationwide in 2025 in MLIT’s “Statistics on Building Construction Starts” (¥1.955 million for lodging use in 2024 and ¥1.203 million in 2019) — gives ¥3.70 billion, or ¥4.08 billion after factoring in +5% increases in each of 2026 and 2027 during construction. Because the site area has not been disclosed, land is assumed at gross floor area ÷ 800% FAR = approx. 702㎡, multiplied by the nearest official land price of ¥1.88 million/㎡ for ¥1.32 billion (a lower bound based on official land prices; market prices may be higher). The total is ¥5.40 billion, or ¥46.1 million per room. Actual acquisition and design terms are undisclosed, so what follows is only a simple estimate indicating market levels in the trade area. For another example of back-calculating the required ADR for a new-build project in the same Chuo Ward, see Mitsubishi Estate’s 10,630 m² Dotonbori Hotel: Required ADR ¥19K–34K.

Against this total investment, assuming a GOP yield (GOP ÷ total investment) of 4.5–5.5%, a GOP margin of 40–50% and occupancy of 80% (set more conservatively than the 82.3% estimated OCC of Chuo Ward business hotels in September 2026), the required ADR is as shown in the table below. The base case (GOP yield 5.0%, GOP margin 45%) gives ¥17,600, and even the low case (4.5%, 50%) gives ¥14,200 — both above the ¥10,578 estimated transacted ADR of Chuo Ward business hotels in September 2026 and the ¥10,661 room-weighted average within 1km. In other words, this project is an investment premised on building a product not for the crowded tier of large business hotels, but for the ¥12,000–17,000 band corresponding to the top quarter to top 10% within 1km. As seen in the previous section, 100–300-room properties actually operate in this band, and if the nationwide accommodation price index keeps stepping up at around 5% a year through 2028, the required level will come relatively closer.

This required ADR also moves with the assumptions for occupancy and total investment. Whereas the table above holds occupancy at 80%, a pessimistic case combining a 10% higher total investment (¥5.94 billion, e.g., if actual land prices exceed official levels), a 40% GOP margin and 75% occupancy pushes the required ADR up to ¥23,200. An optimistic case with a 50% GOP margin and 85% occupancy (above the 82.3% estimated OCC of Chuo Ward business hotels in September 2026) brings it down to ¥14,900, approaching the top quartile within 1km (¥12,877). The second table below reverses the direction, showing the GOP yield obtained for each combination of ADR and occupancy at a ¥5.40 billion total investment and a 45% GOP margin: a 5% GOP yield is reached from around 90% occupancy at an ADR of ¥16,000, 80% at ¥18,000 and 70% at ¥20,000.

There is a basis for the GOP margin assumption. The GOP margin of the 91 operating properties disclosed by Invincible Investment Corporation was 38.9% (fiscal period ended December 2024). We set a range of 40–50% as a conservative value that includes the first year after a new opening. Construction costs rose from ¥1.386 million per tsubo in 2022 to ¥1.955 million in 2024 and ¥2.178 million in 2025. Lodging-use construction starts in Osaka Prefecture reached 18 buildings / 143,401㎡ in 2024, 2.6 times the floor area of 2023 (14 buildings / 54,152㎡), but still only slightly more than half of 2019 (99 buildings / 259,913㎡). Rising construction costs also act as a brake on new supply and could be a tailwind for rates for both the existing stock and the new 2028 property.

Investment Perspective — Ample Absorption Capacity; the Question Narrows to “Which Tier to Sell In”

Summing up, there are three conclusions. First, there is ample capacity to absorb the supply. The 117 rooms equal 0.7% of the 17,584-room operating stock within 1km, and +1.8% even including the 202 rooms in December 2026 — small compared with the trade area’s track record of absorbing +78% in 2017–2019. Second, the demand base is deep. There are 300,000 workers within 1km and 110,000 residents within 1.5km; the estimated OCC of business hotels in September 2026 was 82.3%, running at roughly 80–90% on weekdays. Third, rates have returned to pre-Expo levels. Chuo Ward’s estimated transacted ADR was ¥10,578 in September 2026, −1.8% vs. two years earlier, establishing the normal level after the Expo boom faded. These 2026 figures can serve as the base year for evaluating the 2028 project.

The remaining issue comes down to the choice of price tier. The estimated required ADR (¥17,600 in the base case) is about twice the trade-area median of ¥9,056 and cannot be reached with the same product as the crowded tier of large business hotels. On the other hand, the same 1km radius has properties of 100–300 rooms commanding ¥12,000–24,000, and the 48㎡-per-room floor allocation suits product design for that tier. With the brand and operator undisclosed at this point, it is not possible to infer this project’s positioning from the price ranges of the building owner’s existing brands; but if trade-area rates step up by 5% a year, in line with the nationwide accommodation price index, through the summer 2028 opening, the gap with the required ADR on a 2026 basis will narrow. For site acquisition managers and investors looking at new-build projects in central Osaka, this is a case that asks not “is there oversupply?” but “who will go after demand in which tier?”
