In July 2026, the preparatory association behind the Fujisawa Station South Exit 391 District Urban Redevelopment Project — a plan to replace three commercial buildings at the station’s south exit with a single tower — announced a review of its project plan. The estimated total project cost has swollen roughly 1.5-fold, from about ¥27.0bn to about ¥40.0bn, and completion of the redevelopment building slips three years, from 2032 to 2035 at the earliest. Meanwhile, the official land price standard site on the same block rose 11.5% in a single year, while hotel rates in Fujisawa City rose only 2.1% YoY on a 12-month average. This article focuses on the hotel floors planned for the upper storeys and uses sensitivity tables to show how far the cost overrun pushes up the required ADR, both when the floor is acquired and when it is leased.

Cost Up About 1.5x, Completion in 2035 at the Earliest — What the Review Changed

We begin by establishing where the plan stands, using primary documents and press reports. The 391 District is the block facing the south exit station plaza where three buildings stand side by side — the Fujisawa Meiten Building, the Diamond Building and the CD Building — and Fujisawa City adopted a city planning decision designating it a Type 1 Urban Redevelopment Project in June 2023. According to city council materials, the facility plan calls for a 17-storey building with a total floor area of about 35,200 m², for commercial, office, lodging and other uses, with a multipurpose hall inside the hotel that would serve as a temporary shelter for stranded commuters. Kentsu Shimbun reports that the structure is reinforced concrete with two basement levels and 17 storeys above ground, that Fujita Corporation is the project partner, and that basic design is by Fujita and Akihisa Hirata Architecture Office.

The review affects both cost and timing. According to Kanagawa Shimbun (July 14, 2026), rising material prices and labour costs pushed the total project cost from the initial estimate of about ¥27.0bn to about ¥40.0bn, and it became clear in October 2025 that the project balance would be about ¥8.0bn in the red. In response, the preparatory association postponed the closure of the three buildings from March 2028 to 2031, and completion moves from 2032 to 2035. The Townnews Fujisawa edition reports that design changes such as cutting the number of elevators were also attempted, and that because the existing buildings fill the entire site, the block is structurally ill-suited to securing new floor area that can be sold after rebuilding (reserved floor).

Note, however, that the figures rest on different assumptions depending on the source. Materials Fujisawa City presented to a special committee in November 2024 put the total project cost at about ¥32.1bn (of which about ¥12.5bn is national, prefectural and city subsidies) and the plan period at FY2026–FY2032, so the base date or scope may differ from the “initial about ¥27.0bn” in press reports. The size of the district also varies: the city materials and Kanagawa Shimbun give “about 0.5 ha (about 5,000 m²)”, whereas Kentsu Shimbun writes “site of about 3,180 m²”. The former can be read as the project area including roads and the plaza and the latter as the building site, but this article simply presents both by source. For the hotel floors, too, some reports say “13th–17th floors” and others “12th–17th floors”, and the number of rooms has not been disclosed.

The Growth Gap — Project Cost +48%, Land Prices +13%, Hotel Rates +2.1%

Viewed from the standpoint of the hotel floors, the issue is the gap between how fast costs and revenues are growing. Total project cost rose 48.1%, from about ¥27.0bn to about ¥40.0bn, and the median commercial land price within 1 km of the station rose 13.4%, from ¥478,000/m² in 2025 to ¥542,000/m² in 2026. By contrast, Fujisawa City’s estimated settled ADR rose 2.1%, from a 12-month average of ¥9,500 for September 2024 – August 2025 to ¥9,700 for September 2025 – August 2026 (N=21–23 properties). Over the same period ADR for Kanagawa Prefecture as a whole rose 6.0%, from ¥13,300 to ¥14,100 (N=542–600 properties), so Fujisawa’s increase was more gradual than the prefectural average.

Month by month, though, the picture is somewhat different. The chart below overlays Fujisawa City’s ADR by year: August 2026 came in at ¥12,100, 9.4% above the ¥11,100 of the same month a year earlier. Rates tend to rise in summer, when leisure demand for Enoshima and the Shonan coast is added, and conversely fall to ¥8,500–¥8,800 in February and June. The annual average of just under ¥10,000 can be read as the result of smoothing the gap between the summer peak and the slack months.

On occupancy, recent sell-through is at a high level. Estimated OCC for Fujisawa City’s business hotel category (12–13 properties / 1,041–1,080 rooms, based on listings on major booking sites) was 88.4% in July 2026, 91.9% in August and 87.2% in September. In September, the Monday–Thursday average was 89.2% and Saturday 87.5%, showing that weekday business demand fills rooms to about the same degree as weekends. Note that this figure is an estimate based on the sell-through of inventory sold on booking sites and differs from the actual occupancy rate of each property as a whole.

Location Fundamentals — Standard Site on the Same Block at ¥2.13M/m², +35.7% in Four Years

Turning to the location, land prices are moving in the same direction as project costs. In MLIT’s official land prices (2026) there are five commercial standard sites within 1 km of Fujisawa Station, and all five rose more than 9% YoY, by +9.4% to +13.4%. The highest-priced site, “Fujisawa 5-3”, is located at Minami-Fujisawa 2-1, the same address as the redevelopment district; it is zoned commercial with a 600% floor-area ratio and stands at ¥2.13M/m², up 11.5% YoY. Compared with ¥1.57M/m² in 2022, that is +35.7% in four years, and the median of the five sites also rose 29.7%, from ¥418,000/m² to ¥542,000/m².

Rising land prices feed into the redevelopment’s economics through two channels. One is that the appraised value of the pre-existing assets rises, which works to thicken the floor area that rights holders receive (rights floor). The other is that it pushes up the unit price of the reserved floor sold to recover project costs. Given the “hard to secure reserved floor” structure the press describes, the way an operator comes in is also likely to differ depending on whether the hotel floors are disposed of as reserved floor or held by rights holders and leased out.

The foundation of demand is the concentration of employment around the station. According to the Economic Census (2021) by the Ministry of Internal Affairs and Communications and the Ministry of Economy, Trade and Industry, 2,830 establishments and 37,599 workers are concentrated within a 1 km radius of Fujisawa Station, of whom 24.5% are office workers. The station is a node where three lines meet — the JR Tokaido Line, the Odakyu Enoshima Line and the Enoshima Electric Railway — and the location layers two kinds of demand: business on weekdays, and Shonan and Enoshima leisure in summer and on weekends.

Competitive Landscape — 18 Properties and 1,318 Rooms Within 1 km, Led by Nine Limited-Service Hotels

Next, we check the depth of the market the hotel floors would enter. As far as MetroEngines Research can identify, lodging properties within a 1 km radius of Fujisawa Station increased from 14 properties with 980 rooms at the end of 2017 to 18 properties with 1,339 rooms at the end of 2020, and stand at 18 properties with 1,318 rooms as of 2026 (rebrands of the same building and duplicate registrations that have since been merged are counted as one property). After four properties and 359 rooms were added in the three years 2018–2020, supply has been flat for the past six years.

Of these, the business hotel category with 60 or more rooms comprises nine properties with 1,105 rooms in total, accounting for about 84% of the rooms in the catchment. All are within about 600 m of the station centre, and the largest has 206 rooms.

The next chart shows the distribution of price bands. For ten properties — the nine above plus one city hotel category property of about 30 rooms — it plots estimated settled ADR for September 2025 – August 2026 (12-month average) against room count. The nine limited-service hotels fall within a range of ¥8,000–¥11,100, and the median of the ten properties is ¥9,400. Only the single 30-room property sits in the band around ¥18,000, and no property in the catchment commands this price band at a scale of more than 100 rooms.

Estimating Required ADR — ¥18,000 to Acquire, ¥22,000 to Lease

This is the core of the analysis. Because neither the price nor the rent of the hotel floors has been disclosed, we back-calculated the required ADR under the simplified assumption that “the floor is disposed of at the average unit price obtained by dividing total project cost by the total floor area of 35,200 m²”. At a project cost of about ¥40.0bn the average unit price is ¥1.136M/m² (about ¥3.76M per tsubo); at the initial ¥27.0bn it is ¥767,000/m² (about ¥2.54M per tsubo). Because this unit price also includes demolition, compensation, design and public facility works, it differs from pure building construction cost. For reference, based on MLIT’s Building Starts Statistics, the 2025 construction cost of lodging-use buildings was ¥2.405M per tsubo for steel-frame structures and ¥2.026M for reinforced concrete.

The assumptions of the estimate are as follows. Total floor area per room is set at 40 m², including an allocation of common areas and the multipurpose hall, and estimated OCC at 85%, more conservative than the recent 87–92%. For the acquisition case we assume an expected NOI (net operating income) yield of 5.0% and an NOI margin of 40% of room revenue (an assumed value for the level after deducting property tax, insurance and replacement reserves from GOP). For the lease case, the floor owner is assumed to earn the same 5.0% yield through rent, and the rent an operator can bear is set at 33% of room revenue.

To summarise the results, when the project cost was about ¥27.0bn the required ADR for acquisition was ¥12,400, roughly on a par with the actual ¥12,100 of August 2026. At about ¥40.0bn it becomes ¥18,300, about 1.9 times Fujisawa City’s 12-month average of ¥9,700. In the lease case it is higher by the amount needed to secure the operator’s share, at ¥22,200. Conversely, the floor unit price that the current 12-month average ADR can support works out to ¥602,000/m², equivalent to a project cost of about ¥21.2bn when applied to the entire floor area. Even assuming August’s rate level persisted all year, it would be equivalent to only about ¥26.5bn.

The outlook for construction costs should be viewed as a range. If construction starts in 2031 or later and completion is in 2035, the midpoint of the works falls around 2033. Starting from the current about ¥40.0bn, a 3% annual rise would bring the cost to about ¥49.2bn and a 5% annual rise to about ¥56.3bn, lifting the required ADR for acquisition to ¥22,500–¥25,800. The design review the preparatory association is pursuing works to absorb this increase, and because rising construction costs also restrain new supply nearby, there is an accompanying upside in that competition with the existing market would ease.

The other point to note in the estimate is its sensitivity to floor area per room and to yield. Keeping the project cost at about ¥40.0bn but holding each room to 30 m² lowers the required ADR for acquisition to ¥13,700, bringing it close to actual summer levels. Conversely, making the rooms a more spacious 50 m² would require ¥22,900.

The treatment of subsidies also moves the conclusion substantially. If the roughly ¥12.5bn in subsidies shown in the city’s November 2024 materials is assumed to remain the same after the review, the project cost borne by the floors becomes about ¥27.5bn, and the required ADR for acquisition falls to around ¥12,600. Because the post-review funding plan has not been disclosed, this figure is no more than one illustrative assumption. The estimates in this article are simplified, and actual investment decisions require a detailed feasibility study.

Scale of the Hotel Floors — 132–220 Rooms at 15–25% of Total Floor Area (Estimate)

The number of rooms has not been disclosed, but having a rough sense of scale makes it easier to think about the impact on supply. If the hotel floors account for 15–25% of the total floor area (5,280–8,800 m²) at 40 m² per room, the room count comes to 132–220. This is not a planned figure but an estimate from floor area, and it will move up or down with the number of hotel storeys and the size of the multipurpose hall. Opening within this range would represent an increase of +10.0% to +16.7% on the 1,318 rooms within 1 km of the station, and the acquisition cost of the floors would be on the order of ¥6.0bn–¥10.0bn on an average unit price basis.

Implications for Operators, Rights Holders and Lenders

Pulling this together, a project cost of about ¥40.0bn does not balance as an extension of Fujisawa’s current standard rate band (just under ¥10,000); it balances only on the premise of a product in the ¥15,000–¥20,000 band. Behind this is the growth gap: rates moved only 2% while costs rose nearly 50%. That said, rates have actually reached the ¥12,000 range in summer, and given that there is no large property in the same price band within the catchment, it is also within reach depending on product design.

For operators, it would be useful to compare forms of participation early. When acquiring the floor, compressing floor area per room lowers the required ADR the most, so it is worth considering a configuration centred on rooms of around 30 m² while reflecting upper-floor views and direct station access in the rate. When leasing, combining fixed rent with revenue-linked variable rent could hold down the burden in the early years after opening while sharing summer upside with the owner. With completion in 2035, there should be several opportunities to re-measure construction costs and rates at the point when contract terms are set.

From the standpoint of rights holders and lenders, hotel floors are an option both as a destination for disposing of reserved floor and as a use for rights floor. The economics of placing a hotel on the upper floors of a redevelopment building, and the choice between continuing to hold rights floor and cashing out, both turn on the same variables examined here. In Fujisawa’s case, the block-level condition of thin reserved floor overlaps with the market condition of gradual rate growth, so the next point to watch is how the positioning of the hotel floors is sorted out in the FY2027 revision of the project plan.

Finally, a word on how to read the time horizon. Planned completion is nine years away; in the meantime the three existing buildings will stay open until 2031, and the conversion of the station to an elevated concourse and the redevelopment of the south exit station plaza will proceed first. As far as MetroEngines Research can identify, this redevelopment is the only new-build hotel plan under way within 1 km of the station (based on building confirmation applications as of the survey date; the number of projects and rooms is expected to increase as further applications are filed, so this should be read as the lower bound of the confirmed pipeline at present). For existing properties, this can also be read as time to work on lifting their rate band a notch while supply is flat.

Conclusion

The Fujisawa Station South Exit 391 District redevelopment has been revised, with total project cost up from about ¥27.0bn to about ¥40.0bn and completion moved from 2032 to 2035 at the earliest. The standard site on the same block stands at ¥2.13M/m², up 11.5% YoY, and all five commercial sites within 1 km of the station rose more than 9%, while Fujisawa City’s ADR averaged ¥9,700 over 12 months, up only 2.1% YoY. The required ADR for the hotel floors, estimated from the average floor unit price, is ¥18,300 for acquisition and ¥22,200 for lease, which presupposes a different product design from the ¥8,000–¥11,100 band where the catchment’s nine limited-service hotels sit. Floor area per room, subsidies and rent structure are the three main variables that move the required ADR, and the project plan revision scheduled for FY2027 will be the first milestone for re-measuring these assumptions.
