Hotels built into the same tower as — or on the same block as — condominiums and rental residences are lining up in Japan’s 2026–2031 supply pipeline. Osaka’s Dojimahama with 220 rooms, Okayama Station with 177 rooms, Yokohama’s Kitanaka with 272 rooms: in each case the hotel occupies part of a building whose main floor area is residential. In this article we extract residential mixed-use projects from our planned-project data, which is based on the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) Building Construction Statistics, cross-check every project’s specifications against the developers’ published materials, and quantify the supply impact by matching each project against its catchment’s existing room stock, estimated settled ADR and estimated occupancy.

Seven Residential Mixed-Use Hotel Projects — 1,401 Confirmed Rooms

Our lodging pipeline, built from building-permit data, contained 70 projects and 15,517 rooms at the time of research. Of these, 7 list housing, apartments or residences among their principal uses. The table below shows the results of checking each project’s specifications one by one against developer press releases, redevelopment association disclosures and municipal project-plan announcements. Looking at those 70 projects by the ordering party’s industry, about 73% are commissioned by non-hotel companies.

For the cross-check, we used only figures published by the project owner or the redevelopment association for room counts, residential units, number of floors, gross floor area and completion dates. Items that could not be confirmed in published materials are left blank; no estimates have been filled in.

The first thing that stands out in the table is that projects where “housing and hotel share the same tower” are mixed with projects where they “stand in separate buildings on the same block.” Five of the seven are vertically split towers, with the hotel on the lower side and housing on the upper side. In Osaka’s Dojimahama, the hotel occupies the middle floors of a 40-storey tower with 513 for-sale units above. In Yokohama’s Kitanaka, floors 1–16 are the hotel and floors 18–40 are rental housing, with floor 17 completely separating the two uses. In Nihonbashi, the hotel and rental residences share the upper section of a 52-storey, roughly 284m tower.

The two Okayama projects, by contrast, both use separate buildings. OKAYAMA GATE PLACE places a residential tower (31 floors) and a hotel tower (16 floors) side by side on its west block, linked by a pedestrian deck. The Nodayacho district is likewise split into a 19-storey residential tower and a 12-storey hotel tower. Even within “residential mixed-use,” operating constraints differ completely depending on whether the uses share one tower or sit in separate buildings. We return to this difference later.

Stacking Up-Front Residential Proceeds and Long-Term Hotel Income on One Site

There is a structural business logic behind this development format appearing in numbers. For-sale housing recovers capital at completion and handover, while a hotel generates income over the long term after opening. Combining both in a single project lets developers pair cash flow during the development period with recurring income after completion. Mitsui Fudosan positions the Dojimahama project as a “large-scale integrated development of condominiums and a hotel,” with sales, development and hotel operation split among group companies.

For projects advancing under the urban redevelopment framework, another factor comes into play. Under rights conversion, residential and retail floor space is allocated to existing rights holders, and participating members acquire the reserved floor space to fund the project. Structurally, residential floor space is easy to use both as floor returned to rights holders and as reserved floor to be sold. The two Okayama projects and the Nihonbashi project are all Type 1 urban redevelopment projects, with developers joining as participating members. The hotel is typically built in as the use that brings activity and exchange to the block, often combined with a convention hall and retail. OKAYAMA GATE PLACE’s hotel tower stacks retail on floors 1–3, a convention hall on floor 4, offices on floors 5–6 and the hotel on floors 7–16. Whether a rights holder does better keeping a hotel as rights floor or cashing out depends on the hotel’s achievable ADR over a 20-year horizon.

There are also the questions of the mix of uses required to obtain floor-area-ratio bonuses and of absorbing the floor area of large blocks that housing alone could not fill. Filling hundreds of thousands of square meters with housing alone is difficult from a demand standpoint, all the more so in regional core cities where office demand is hard to predict. A hotel can secure a certain level of profitability with relatively little floor area and also helps give the block its public face.

866 Rooms Concentrated in 2027, Then a Jump to FY2029 and FY2031+

Arranging the six projects whose room counts could be confirmed by planned opening/completion year shows supply heavily skewed toward 2027. Excluding Oimachi’s 285 rooms, which opened in March 2026, Dojimahama’s 220, Okayama Station’s 177, Kitanaka’s 272 and Nihonbashi’s 197 — 866 rooms in total — are all scheduled to enter the market during 2027. After that, Shibuya is slated for completion in FY2029 and Nodayacho in FY2031 or later, leaving a gap.

Care is needed not to read the “gap” from 2028 onward as supply drying up. Planned-project data is based on building-permit applications, which are usually filed 1–2 years before opening. The counts for 2029 and beyond therefore include only projects already filed and will certainly rise as new applications are added. They should be read as a floor for the currently confirmed pipeline.

1.5%–3.0% of Existing Catchment Stock — Smaller Than a Standalone Opening

Absolute room counts alone cannot measure supply impact. We drew a radius around each project’s site, summed the rooms of properties within that catchment with listed-price observations in the most recent 3 months, and calculated how large the added rooms are relative to the existing stock.

In all three catchments, the supply increase falls within 1.5%–3.0%. Because the hotel sits inside a building whose main floor area is residential, the floor space that can be allocated to the hotel is limited, so each project stays at around 200–300 rooms. Compared with standalone hotel developments of 500+ rooms, the supply shock to the catchment is structurally small.

Okayama makes this clear in numbers. In August 2026, a new 600-room-class hotel — one of the largest in the prefecture — opened near Okayama Station. If the room stock within 1km of the station just before that opening was about 5,400 rooms, that single hotel added about 11%. The 177 residential mixed-use rooms arriving in spring 2027 amount to about 3.0% of current stock — less than a third of that one standalone opening. Residential mixed-use hotels are better understood not as “vehicles for mass supply” but as a form of supply that gradually thickens the existing stock.

Map of the Seven Project Sites

Okayama: 177 Rooms Arrive in Spring 2027 Amid 86% Occupancy and Rising Rates (Jun–Aug 2026)

Two of the seven projects are in Okayama Kita Ward, so we first check the receiving market with our data. Okayama Kita Ward’s estimated settled ADR was ¥9,226 in August 2026 (N = 50 properties), up 5.8% YoY from ¥8,718. Overlaying the three years 2024 to 2026 month by month shows the level stepping up year after year.

On the supply-demand side, Okayama Kita Ward’s estimated occupancy was 88.2% in June 2026, 86.9% in July and 86.3% in August (each based on 23–24 properties, about 2,700 rooms) — above 86% for three consecutive months. Holding this level even in the month a 600-room-class hotel opened in August 2026 indicates that demand in the station catchment has real depth. The market is absorbing new supply while rates also step up, making it a relatively favorable environment for the 177 rooms joining in spring 2027.

That said, these 177 rooms are not a limited-service product: the hotel includes dining, a guest-only lounge, bathing facilities and a gym, with 83 doubles and 94 twins. It appears to target a different price band from the limited-service hotels at the core of the existing station-area stock. Given that Okayama Kita Ward’s estimated settled ADR sits in the high-¥8,000s to low-¥9,000s, there is relatively more room at the upper price tier.

The other project, the Nodayacho district, has about 250 rooms, but according to the project plan published by Okayama City and the redevelopment association’s materials, completion is scheduled for FY2031 or later — nearly five years after the 177 rooms of 2027. It is not appropriate to add the two Okayama Station projects together as “supply concentrated in the same period.” Only the 177 rooms should actually be factored into supply plans around 2027.

Osaka and Yokohama: 2027 Openings Coincide With a Rate Correction

The two catchments that Dojimahama and Kitanaka enter, by contrast, are in a phase where recent rates are below the prior year. Osaka Kita Ward’s estimated settled ADR was ¥9,890 in August 2026 (N = 74 properties), down 32.3% YoY from ¥14,610. 2025 coincided with the World Expo, and levels from April onward were far above normal. 2026 is the hangover phase, and the high comparison base widens the decline.

Compared with the same month in 2024, however, August 2026’s ¥9,890 is -4.0% versus ¥10,306 in August 2024 — essentially back in the pre-Expo range. Projecting forward from the 2025 spike would overstate things, but measured against 2024 the market is not collapsing. By spring 2027, when Dojimahama’s 220 rooms arrive, the prior-year comparison will already have passed through the hangover phase.

Yokohama Naka Ward’s estimated settled ADR was ¥11,156 in August 2026 (N = 51 properties), down 16.0% YoY from ¥13,278. Estimated occupancy was 80.7% (49 properties, 9,971 rooms), the lowest of the three catchments. 272 luxury-tier rooms will join in 2027. The addition to existing stock is small at 1.8%, but because the price band being added is far above the catchment’s current core, it may act for nearby properties less as competition and more as a move that lifts the market’s ceiling.

Note that Conrad Yokohama (272 rooms), Waldorf Astoria Tokyo Nihonbashi (197 rooms) and Waldorf Astoria Residences Tokyo Nihonbashi (71 units) are all among the 13 upcoming Japanese openings Hilton listed as of August 25, 2026, each marked “opening 2027.” The room counts in our table match these disclosures.

How Far Would Occupancy Fall on Flat Demand? Absorption Scenarios for Three Catchments

A 1.5%–3.0% supply increase does not by itself indicate how heavy the burden on the receiving market is. How estimated occupancy moves when rooms are added depends on how much demand grows at the same time. Here, starting from each catchment’s latest estimated occupancy (August 2026), we set three demand scenarios (change in rooms sold) and estimate occupancy after the added rooms enter.

In the base case (flat demand), Okayama Station comes to 83.8%, Dojimahama to 82.9% and Kitanaka-dori to 79.3%. Each is a decline of only about 2–3 points from current levels — not the double-digit swing seen when a large standalone hotel opens. By definition, the demand growth required to hold occupancy at current levels equals each supply increase: +3.0%, +1.5% and +1.8%.

Okayama offers a real example of whether that level of demand growth is realistic. A 600-room-class opening in August 2026 increased stock within 1km of the station by about 11%, yet Okayama Kita Ward’s estimated occupancy that month was 86.3%, not a major break from 88.2% in June and 86.9% in July. For a market that largely absorbed an 11% increase, 3.0% is a relatively light load.

Viewed on two axes, 3% demand growth fully offsets +3.0% supply and holds occupancy steady. Conversely, if supply builds to +6.0% while demand falls 6%, occupancy drops to 76.5% — about 10 points below today. A single residential mixed-use project will not push a market into that zone, but it is the level to reference if other standalone openings overlap in the same catchment.

Four Issues Operators Should Check Before Committing

Residential mixed-use projects carry more operating constraints than standalone hotel buildings. From the perspective of an operator evaluating them as candidate sites, we organize the practical issues that can be read from published materials and each project’s layout. The following is a general list of considerations and does not describe the contract terms of any specific project.

Of these four points, 1–3 weigh heavily for same-tower projects and lightly for separate-building ones. Separate-building projects, on the other hand, secure standalone floor space for the hotel but depend more on block-wide branding and pedestrian-flow design. OKAYAMA GATE PLACE’s linking of its residential and hotel towers with a pedestrian deck, and stacking retail, a convention hall and offices beneath the hotel, can be read as an attempt to resolve this dependency through design.

Conclusion — Read the Mix of Uses, Not the Volume of Supply

Cross-checking the seven residential mixed-use hotel projects against published materials confirmed 1,401 rooms, of which 866 are concentrated in 2027. However, the addition to each catchment’s existing stock is only 1.5%–3.0%, a small supply impact compared with standalone hotel developments. Set against the roughly 11% added by a single 600-room-class hotel near Okayama Station in August 2026, the scale of residential mixed-use projects is clear.

It is therefore more practical to read this development format not as “supply pressure” but in terms of “which price band and which guest segment the hotel targets within its limited floor space.” Dojimahama, Kitanaka and Nihonbashi are all configured for the upper price tier, going after a different segment from the existing core price band. Okayama Station’s 177 rooms, with dining, a lounge and bathing facilities, likewise appear to seek a different position from the limited-service hotels that dominate the station-area stock.

From the developer or redevelopment association side, the reasons for choosing this format can be summarized as: it puts up-front residential proceeds and long-term hotel income in one project, residential floor space is easy to handle in rights conversion, and a diverse mix of uses helps with floor-area bonuses. From the operator side, operating constraints change significantly depending on same-tower vs. separate-building layout, and the counterparty for decisions changes depending on for-sale vs. rental housing. In site evaluation, confirming these two axes early — in addition to room count and location — is the practical dividing line.
