According to a plan announced on July 22, 2024 by Tokyo Tatemono, World Trade Center Building, Inc. and Accor, Raffles — Accor’s top-tier luxury brand — will open its first property in Japan, Raffles Tokyo (ラッフルズ東京), in Hamamatsucho. The hotel will occupy the 36th to 46th floors of the Main Building & Terminal of the World Trade Center Building, now under reconstruction, with 130 rooms, all 60 m² or larger, and is scheduled to open in 2028. The room stock within a 1 km radius of Hamamatsucho Station grew 27.5%, from 6,491 rooms in 2017 to 8,279 rooms in 2026, so adding 130 rooms lifts it by only 1.6%. What matters more is the price tier: properties with listed prices of ¥100,000 or more number just 4, with 1,376 rooms, and the 130 rooms will enter that tier. This article walks through the price structure of the 1 km catchment, the estimated settled ADR in Minato Ward, land prices and flood risk, and the required ADR back-calculated from construction cost and target yield, to see under what conditions these 130 rooms work.

Plan Overview — 130 Rooms on Floors 36–46 of the Main Building & Terminal, Opening 2028

Raffles Tokyo will be part of the World Trade Center Building reconstruction, the “Hamamatsucho 2-chome District 4, Block A” project (Minato-ku, Tokyo). Tokyo Tatemono and World Trade Center Building, Inc. are the developers, and Accor will run the hotel under a management contract. It is a combination that is becoming standard in central Tokyo redevelopment: a foreign brand that owns neither land nor building and only operates, with a luxury hotel placed on the upper floors of a mixed-use office tower.

All 130 rooms will be 60 m² or larger, and the hotel will have three restaurants, the brand’s signature “Long Bar” and “Writers Bar”, an indoor pool and a spa. The plan outline also lists banquet and meeting rooms and a gym. The Main Building & Terminal as a whole is scheduled to open partially in 2027 and then in phases, with the hotel following the year after. All figures below reflect the plan as of July 22, 2024, and the announcement notes that details may change without notice.

When the plan was announced in 2017, Block A as a whole had a site area of 21,007 m² and a gross floor area of 287,985 m². That is a floor-to-site ratio of about 13.7x, with far more floor area secured through integrated development than the 600% floor area ratio designated by zoning. The estimates below use this ratio to allocate the land share per m² of gross floor area.

Room Stock Within 1 km — From 6,491 to 8,279 Rooms in Nine Years; 130 Rooms Add 1.6%

Tracing the lodging facilities within 1 km of Hamamatsucho Station back by opening year, the stock grew from 35 properties and 6,491 rooms at the end of 2017 to 44 properties and 7,783 rooms in 2020. This reflects the string of limited-service hotel openings during the inbound boom, with 1,292 rooms added in those three years alone. From 2021 to 2024 the stock held flat at 7,700–7,900 rooms; in 2025 additions including Fairmont Tokyo (217 rooms) brought it to 8,241 rooms, and in 2026 it stands at 52 properties and 8,279 rooms.

Raffles Tokyo’s 130 rooms are only +1.6% against this 2026 stock. Measured by supply volume, the impact on the area is small, so the question shifts from quantity to which price tier the hotel enters. Of the active properties with a selling price observed in the most recent 3 months — 50 properties with 8,169 rooms — the 15 large properties with 201 or more rooms account for 4,886 rooms, about 60% of active rooms.

The 1 km Catchment by Price Tier — Only 4 Hotels and 1,376 Rooms Listed at ¥100k+

Next, the 44 active properties (7,704 rooms) in the hotel categories were divided into five tiers by their listed price (all-plan average) over the last 12 months. The thickest tier is ¥25k–50k with 18 properties and 2,129 rooms, followed by ¥15k–25k with 15 properties and 2,058 rooms. Properties at ¥50k and above number 11 with 3,517 rooms, or 45.7% of the stock by room count. Hamamatsucho, Shibakoen and Shiodome have long been home to city hotels and large international hotels, so the upper end of the price range is also well populated.

Narrowing to ¥100k and above leaves four hotels with 1,376 rooms: The Prince Park Tower Tokyo (ザ・プリンス パークタワー東京, 603 rooms), Conrad Tokyo (コンラッド東京, 291 rooms), mesm Tokyo, Autograph Collection (メズム東京オートグラフコレクション, 265 rooms) and Fairmont Tokyo (フェアモント東京, 217 rooms). Raffles Tokyo’s 130 rooms would increase this tier’s room count by 9.4%. Small as an addition to total volume, it is a meaningful addition within the top tier.

The line-up of these four hotels also shows that Hamamatsucho has been a market that receives international brands’ “first in Japan” openings. According to the history in Hilton’s “Company Overview”, Conrad Hotels & Resorts entered Japan with Conrad Tokyo in 2005, and Fairmont opened its first Japanese property, Fairmont Tokyo (in Shibaura, inside BLUE FRONT SHIBAURA), in July 2025. Once Raffles Tokyo opens, three upscale brands will have opened their first hotel in Japan within the same 1 km catchment over roughly 20 years. Moreover, Fairmont and Raffles are both upper-tier Accor brands, which will put two hotels of the same group less than 500 m apart.

Minato Ward Estimated Settled ADR — ¥16,100 in September; 12-Month Average Up 5.1% YoY

To gauge the area’s typical level, we checked Minato Ward’s estimated settled ADR (median of properties in the ward). September 2026 was about ¥16,100 (N=133 properties), 6.6% below about ¥17,200 (N=127) a year earlier. June through August were also below the prior year, so from summer into early autumn hotels kept rates down to protect occupancy. On the other hand, April was about ¥22,100, up 7.6% YoY, and the 12-month average for October 2025–September 2026 was about ¥17,600, 5.1% above the previous 12 months (about ¥16,700). On a full-year view, the rate level itself has moved up.

That said, the ward median reflects typical properties, centered on limited-service hotels, and is a different market from the top tier Raffles Tokyo is aiming at. As a pointer to the top tier, Fairmont Tokyo in the same 1 km catchment had an estimated settled ADR of ¥92,000–¥163,000 per month over the 7 months that could be calculated between October 2025 and September 2026, averaging about ¥123,000. A settled level averaging above ¥100,000 is evidence of the depth of upscale demand in this market.

On the supply–demand side, we lined up occupancy across Tokyo (OTA listed-inventory basis, estimated) by price tier. Properties listed at ¥100k or more ran at 83.6% in September 2026; with only 7–19 properties in the sample the monthly swings are large, but June reached 90.7%. The deluxe category stayed at 88–93% from June through September.

Location — Hamamatsucho Land Prices Up 40–50% in Four Years; Commercial Zone with 600% FAR

For the site itself, we checked the conditions at the planned location (2-4 Hamamatsucho, Minato-ku) in the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) Real Estate Information Library. It is zoned as a commercial district, with a designated floor area ratio of 600% and a building coverage ratio of 80%. The official land price point 240 m from the station (Minato 5-28, Hamamatsucho 2-chome) was ¥2.75 million per m² in 2026. Hamamatsucho 1-chome (Minato 5-27) rose from ¥1.72 million in 2022 to ¥2.51 million in 2026, and Shiba-Daimon 2-chome (Minato 5-12) from ¥2.41 million to ¥3.59 million — gains of 40–50% in four years. In 2026 all three points rose 16–17% year on year, so land price growth is accelerating.

The site falls within a flood inundation zone (maximum assumed scale), in the 0.5 m to under 3.0 m depth category. Because the rooms are on the 36th to 46th floors, direct impact on guest rooms is hard to envisage, so the focus of evaluation will likely be flood protection for the low-rise elements such as electrical and plant rooms and the porte-cochère, and the robustness of the business continuity plan (BCP). On transport, JR Hamamatsucho Station’s daily passengers fell from about 324,000 in FY2019 to about 194,000 in FY2021 before recovering to about 253,000 in FY2023. A direct Tokyo Monorail link to Haneda Airport and proximity to both Shinagawa and Tokyo shinkansen stations make it easy to capture both affluent international travelers and domestic business demand.

Required ADR Estimate — ¥96,000 per Room in the Base Case, with Wide Swings by GOP Margin

So what room rate would these 130 rooms need to work as an investment? We stacked up building, ancillary costs and land share and back-calculated the required ADR from a target yield, using three sets of assumptions. For construction cost, we used the 2024 national average for “accommodation use” in MLIT’s Statistics on Building Construction Starts (about ¥1.96 million per tsubo; 1 tsubo ≈ 3.3 m²) as a floor reference and set a range of ¥2.5–3.5 million per tsubo assuming luxury specifications. The high case additionally allows for about 10% construction inflation over two years during the build, giving ¥3.87 million per tsubo (Turner & Townsend forecasts 6.0% construction cost inflation for Tokyo in 2026). Ancillary costs (FF&E, design, etc.) were set at 15% of building cost.

For the land share, the official land price 240 m from the station (¥2.75 million per m²) was divided by Block A’s floor-to-site ratio of about 13.7x to get about ¥201,000 per m² of gross floor area, which was then multiplied by the gross floor area. Gross floor area per room was set at 150–180 m², reflecting rooms of 60 m² or more plus three restaurants, two bars, banquet space, a spa and an indoor pool (for an example of a small luxury hotel with generous floor area per key, see Palace Hotel Hakone 2029: 69 Rooms, 186 m² per Key). Applying the upscale-type unit figures from our earlier article “Hotel Construction Cost ¥8.7M–71.4M per Room” (135.8 m² of gross floor area and about ¥71.4 million per room, 2024 RC construction basis) directly to 130 rooms gives a building cost of about ¥9.29 billion, but this project, with large rooms on the upper floors of a super high-rise, was estimated on heavier assumptions.

In the base case, total investment is about ¥29.5 billion, or about ¥227 million per room, and the required ADR is ¥96,200. The low case gives ¥48,400 and the high case ¥186,500 — a spread of about 4x across the three scenarios. The biggest driver of the spread is not construction cost but operating margin. Luxury hotels carry heavy labor costs in restaurants and spas, and a 5-point move in GOP margin (gross operating profit margin = gross operating profit, i.e., total revenue less departmental direct costs and undistributed expenses such as administration and sales, as a share of revenue) changes the required ADR substantially. The chart below holds the base-case investment fixed and varies only the target yield and GOP margin.

At a 35% GOP margin, even a 5.5% yield requires an ADR of only about ¥94,000, below Fairmont Tokyo’s estimated settled level (about ¥123,000). At 30%, a 5.0% yield requires about ¥107,000; at 25%, even a 4.0% yield requires about ¥114,000. Varying occupancy in the base case gives about ¥91,000 at 85%, about ¥103,000 at 75% and about ¥110,000 at 70%, so a 5-point difference in occupancy translates into roughly a 5–7% difference in required ADR. The picture is that, alongside pricing power, the operating capability to turn F&B and wellness revenue into profit determines the economics of these 130 rooms.

Comparing the swings in Table 6, raising the GOP margin by 5 points from 30% to 35% (about ¥96,000 → about ¥77,000 at 80% full-year occupancy, −20%) has more than three times the effect of raising occupancy by 5 points from 80% to 85% (about ¥96,000 → about ¥91,000, −6%). At a 25% GOP margin, even 85% occupancy (full-year assumption) requires an ADR of about ¥121,000, roughly level with Fairmont Tokyo’s estimated settled rate (about ¥123,000). Stacking rate and occupancy alone struggles to get there; profit design for F&B and spa moves the estimate’s assumptions the most.

Conditions for Success and Upside — Rate, F&B, and Brand Distribution

From the owner’s perspective, when an international brand is brought in under a management contract, upside in room rates depends on the brand’s distribution power, and margins depend on how the operator designs F&B and labor costs. In a market where land prices have risen 40–50% in four years, allocating upper floors to a hotel is also a comparison of whether that space can earn more than office use. We also examined the decision to devote the upper floors of a super high-rise to hotel-type space, in terms of floor economics, in Tokyo Station’s YAESU CORE: 184 Serviced Residences on Floors 40–43, 2029. Laying out the required ADR under three sets of assumptions is, in effect, preparing a yardstick for that comparison.

Summary

Raffles Tokyo’s 130 rooms are only a 1.6% addition to the room stock within 1 km of Hamamatsucho Station (8,279 rooms), but a 9.4% addition to the top tier listed at ¥100k or more (4 hotels, 1,376 rooms). Minato Ward’s overall estimated settled ADR was about ¥16,100 in September 2026, 6.6% below a year earlier, while the 12-month average was up 5.1% YoY, and Fairmont Tokyo in the same catchment runs at an estimated settled ADR of about ¥123,000. The required ADR back-calculated from construction cost and yield is about ¥96,000 in the base case, with a range of about ¥48,000–¥186,000, and GOP margin matters more than rate in determining success. From the phased opening of the Main Building & Terminal in 2027 to the hotel’s opening in 2028, how much deeper upscale demand becomes in this station-integrated redevelopment will be the gauge of these 130 rooms’ upside.

* Figures in this article are as of the time of research (October 2026). Opening date, room count and facilities reflect the plan announced on July 22, 2024 and may change. The required ADR is an estimate based on public information and industry benchmarks, not the operator’s planned figures.
