On April 21, 2026, Shiro Co., Ltd. (株式会社シロ), the company behind the cosmetics brand SHIRO, announced that Sunagawa Park Hotel (砂川パークホテル), one minute on foot from JR Sunagawa Station in Hokkaido, will reopen as “PARK SHIRO” on Tuesday, January 19, 2027. The 24-room hotel, born in 1986 out of local demand for wedding venues, has been fully closed for renovation since October 1, 2025. When it reopens it will be a mixed-use complex: “Minna no Hotel” (みんなのホテル) with 19 rooms in five types, an 18-unit serviced housing for older people (サービス付き高齢者向け住宅, “sako-ju”) called “Minna no Ouchi” (みんなのおうち), a bathhouse with sauna, a 64-seat hall with round tables, a 38-seat restaurant and a secondhand shop. This article examines that floor allocation, which removes guest rooms and adds housing, through three lenses: the population structure within 1.5 km of the station, room rates in the Sorachi region, and the regulatory side (the registration standards for serviced senior housing and the building-confirmation requirement for a change of use).

What PARK SHIRO Consists Of: How a Wedding Hotel Became a “Culture Base”

First, the background. Sunagawa Park Hotel opened in 1986 in response to residents asking for “a hotel where we can hold weddings in Sunagawa,” and has been sold on major booking sites as a 24-room city hotel. While SHIRO was building its production base “Minna no Kojo” (みんなの工場) in Sunagawa, it launched the “Minna no Sunagawa Project” (みんなのすながわプロジェクト) in June 2021. Across 16 workshops, participants repeatedly asked for the Park Hotel to be revived, and about a year later, in June 2022, Shiro acquired management rights to the hotel.

The plan has changed shape in stages. The first announcement in March 2024 said the company would “keep the building as it is and aim for completion in summer 2027.” A local business outlet covering the April 2024 briefing reported a ¥2.0 billion total project that would keep 25 guest rooms and add adjacent single-storey wooden serviced senior housing: five buildings of two units each (10 units). The final form presented in April 2026, after the groundbreaking ceremony on June 24, 2025, narrowed the hotel to 19 rooms in five types, expanded the senior housing to 18 units, and raised the project cost to ¥2.7 billion (including a ¥780 million subsidy). The plan clearly moved toward fewer guest rooms and a larger role for housing, bathing and the hall.

Laid out by published figures, the facility has three layers: lodging (19 rooms), housing (18 units) and community use (64-seat hall, 38-seat restaurant, sauna bathhouse, study lounge, secondhand shop and a traditional candy shop). The subsidy project summary describes “the only banquet hall in the city,” “the only large bathhouse with a sauna in the city,” and states that “staffing for the senior housing will be shared with the hotel.” That operating design, with lodging and housing sharing staff and facilities, is what sets this project apart from a simple room-reduction renovation.

Splitting Floor Space Between Lodging and Housing: Sensitivity Tables for 19 Rooms of Room Revenue and 18 Units of Rent

How does this floor allocation look on the revenue side? Rents and service fees have not been published, so we do not estimate them. Instead, we apply regional rate levels to the published room and unit counts in sensitivity tables. For lodging, we use three reference rates: the pre-closure Sunagawa Park Hotel’s own estimated settled ADR (12-month average of ¥7,370 for October 2024–September 2025, N=1 property), the 12-month average for Hokkaido business hotels (October 2025–September 2026, ¥8,954, 419–441 properties), and the 12-month average for all of Hokkaido (same period, ¥10,123, 865–960 properties). These are rounded to ¥7,400, ¥8,950 and ¥10,100.

At 19 rooms and 60% occupancy, annual room revenue ranges from about ¥30.8M at a ¥7,400 rate to about ¥42M at ¥10,100. The gap versus keeping 24 rooms at the same rate and occupancy, in other words the revenue lost from the 5 removed rooms, is about ¥8.1M a year on the ¥7,400 basis. Passing that number to the housing side: assuming the 18 units are 95% occupied, monthly rent plus common-area fees of more than about ¥39,500 per unit would offset the lost revenue from the 5 rooms through rent alone. This is not a rent forecast; it is a break-even guide derived only from the published room and unit counts. Conversely, for the break-even ADR at which converting the guest rooms themselves into apartments or dormitories would yield more rent than lodging revenue, our analysis Hotel-to-Residential and Dormitory Conversion: Break-Even ADR of ¥3,800–4,600 runs the numbers for three markets including Sapporo.

Source: Estimates by MetroEngines Research & Consulting. Based on 18 units. Assumed values excluding meals, nursing care and living-support service fees. A private survey puts the national median monthly cost of serviced senior housing (rent, management fee, meals, etc. combined) at ¥153,000 (Minna no Kaigo Research Institute, August 2026, N=4,945)

What matters here is less the size of the amounts than the nature of the income. Room revenue swings with season and day of week, while housing rent is level throughout the year. The estimated settled ADR for all of Hokkaido ranges 1.5x within the year, from ¥12,230 in August 2026 to ¥7,955 in April. Layering 18 housing units on top of 19 guest rooms can be read as building a dampener for that swing into the floor allocation itself. The targets in the subsidy project summary (employees involved in the subsidized project from 23 to 70, labor productivity from ¥7.95M to ¥13.36M per person, FY2027 to FY2030) are also meant to be achieved by the whole facility, including the bathhouse, hall and restaurant, and are not a measure of lodging alone.

Population Within 1.5 km of the Station Falls 30.5% by 2040: Why Add Housing in a Catchment Where 4 in 10 Are 65+

The backdrop is the population structure of the catchment. Within a 1.5 km radius of PARK SHIRO (80 mesh cells), the resident population fell from 6,668 in 2020 to 6,048 in 2025 and is projected to reach 4,637 in 2040 (−30.5% vs 2020) and 2,462 in 2070. In 2025, residents aged 65+ numbered 2,409 (39.8%), those aged 15–64 numbered 3,168 (52.4%) and those under 15 numbered 473 (7.8%), roughly the same level of aging as the city as a whole (15,231 residents on the Basic Resident Register as of January 1, 2025; 40.4% aged 65+).

At the mesh level, population is concentrated west of the station, in the built-up area running from along National Route 12 to Nishi 2-jo through 4-jo, and the share of older residents exceeds 32% in most cells. The shading on the maps shows a two-sided picture: the resident population that supports demand for hotel rooms is thinning, while the older residents at the core of housing demand remain dense within walking distance of the station.

The employment side is worth checking too. According to the 2021 Economic Census, there are 334 private establishments with 2,263 employees within 1 km of the station, of which office-type establishments account for only 5.7%. The business base that would support weekday corporate travel is limited. The pillars of lodging demand are instead visitors linked to “Minna no Kojo” (opened April 2023; 300,000 visitors a year, 25.1% from outside Hokkaido, according to the subsidy project summary) and through traffic, given the location roughly midway between Sapporo and Asahikawa. The subsidy project summary’s stated aim of “pairing overnight stays with tourism that is mainly day trips” can be read as the answer to this structure.

Sorachi’s Lodging Market and Supply: Takikawa ¥6,046, Iwamizawa ¥7,803, and Only One Station-Front Property with Observable Prices

To think about the post-reopening price level, rates in neighboring cities are the reference. In Sunagawa, the pre-closure Park Hotel was the only property for which an estimated settled ADR could be calculated, so the city-level series stops in September 2025. The series continue for neighboring Takikawa (3–5 properties) and Iwamizawa (6–7 properties), whose 12-month averages for October 2025–September 2026 were ¥6,046 and ¥7,803 respectively. In 2026, Takikawa’s monthly figures have hovered around ¥6,000 (in the ¥5,800–¥5,900 range in April and May), and in July it recorded ¥6,592, up 20.8% from the same month a year earlier (¥5,457). Because the property count is small, a price change at a single property can easily move the city figure, but the data do indicate that Sorachi’s station-front business segment has been trending upward.

Supply is thinner still. Taking a property-by-property inventory of facilities in the MetroEngines Research hotel master within a 1.5 km radius of PARK SHIRO, the lodging facilities are Sunagawa Park Hotel (24 rooms) plus Sunagawa Ekimae Ryokan (砂川駅前旅館, 20 rooms), Shizukaso (静香荘, 16 rooms), Kanematsu Hotel (金松ホテル, 15 rooms), Tanaka Ryokan (田中旅館, 15 rooms), Yamashita Ryokan (山下旅館, 10 rooms), Osada Ryokan (おさだ旅館, 8 rooms) and a one-room vacation rental that opened in April 2026, for a total of 109 rooms. However, Sunagawa Park Hotel was the only one whose selling prices were observed on major booking sites from January 2025 onward; no prices were observed for any of the others. In other words, the 24 pre-closure rooms were all of the station-front rooms bookable through those sites, and after reopening the 19 rooms will effectively be the online inventory of central Sunagawa.

We also checked the basic site conditions in MLIT’s Real Estate Information Library. The site is in a commercial zone (floor area ratio 400%, building coverage ratio 80%), a zoning category that permits hotels, housing, bathhouses and shops alike. The nearest land price survey point (Nishi 2-jo Kita 5-chome, 550 m from the station) has declined every year, from ¥10,300/㎡ in 2022 to ¥9,800/㎡ in 2026, but the rate of decline has stabilized from −2.8% in 2022 to −1.0% from 2024 onward. Average daily boardings at JR Sunagawa Station were 1,364 in 2018, 1,304 in 2019, 956 in 2020 and 1,142 in 2023, still recovering from the 2020 slump. As planning points to note, the site lies within the flood inundation zones of the Ishikari, Sorachi and other rivers (inundation depth ranked 0.5 m to under 3.0 m under the maximum assumed scale) and falls into a landform category considered prone to liquefaction. For a facility that includes housing for older people, designing evacuation routes and vertical evacuation to the second floor and above becomes the facility requirement that answers these conditions. Hazard exposure can also be converted into area coverage ratios and overlaid on estimated settled ADR and disaster-prevention capex; analyses of this kind across multiple trade areas are a useful complement when evaluating station-front sites like this one.

The Regulatory Side of Putting Housing on Hotel Land: Serviced Senior Housing Standards and When a Change of Use Needs Building Confirmation

To sum up so far, PARK SHIRO’s configuration is: “reduce rooms in the existing hotel building and reallocate the floor space to bathing and the hall, and build the housing new on the parking lot.” This configuration has two implications on the regulatory side.

The first is the registration standard for serviced senior housing. Serviced senior housing is a registration system under the Act on Securement of Stable Supply of Elderly Persons’ Housing, jointly administered by MLIT and the Ministry of Health, Labour and Welfare. Registration with the prefectural governor requires each dwelling unit to have a floor area of 25 ㎡ or more in principle (18 ㎡ or more where there is sufficient shared space such as a living room, dining room and kitchen); a kitchen, flush toilet, storage, washbasin and bathroom; a barrier-free structure; at minimum, status-check (safety confirmation) and life-consultation services; and a contract that secures long-term residence, with protective measures for any advance payments. The design SHIRO presented in 2024, “every unit a corner unit with light from two sides, with Hokkaido-grown todomatsu fir on floors, walls and ceilings,” is built as dwelling units separate from the hotel rooms on the premise of these area and equipment standards. Because lodging and housing take fundamentally different approaches to floor area, building the housing as a separate structure makes it easier to meet the registration standards than converting hotel rooms directly into dwelling units.

The second is change of use under the Building Standards Act. Under the amended Building Standards Act fully in force from June 25, 2019, the threshold at which a change of use requires building confirmation was raised to more than 200 ㎡ of changed floor area for special buildings (previously more than 100 ㎡). Hotels and ryokan are special buildings, and apartment buildings and dormitories are also special buildings, so converting a hotel’s guest-room floors to housing requires a confirmation application once it exceeds 200 ㎡, and the daylighting, party-wall and evacuation provisions for residential use must be met. At PARK SHIRO, the housing is in a newly built structure, while the existing hotel building rearranges its floors within hotel-type uses: lodging, dining, banquets and bathing. This does not eliminate the need for building confirmation, but it avoids applying residential-use provisions retroactively to the existing building, and can serve as one model when a regional station-front hotel takes on a housing function. For how far the 200 ㎡ threshold and the April 2025 narrowing of the Category 4 special exemption extend to the renovation procedures of small inns, see When Lodging Renovations Require Building Confirmation.

That said, this model presupposes room to spare on the site. At PARK SHIRO, the new senior housing on the current parking lot and the purchase of city-owned land north of the station plaza (reported in May 2025) are what create floor space for the new building. Reports that Shiro will work out a development policy with the city, which manages the station plaza, position this as a case where private hotel revitalization and the redevelopment of public space move forward together.

Summary: How to Read the Revival of a Small Station-Front Hotel in Numbers

The conversion of Sunagawa Park Hotel into PARK SHIRO is a ¥2.7 billion plan that reduces a 24-room hotel to 19 rooms while fitting 18 housing units, a 64-seat hall, a 38-seat restaurant and a sauna bathhouse onto one site. The resident population within 1.5 km of the station will fall by 30% by 2040, and people aged 65+ already account for 40%. Estimated settled ADR in Sorachi’s station-front business segment is trending up, at ¥6,046 in Takikawa and ¥7,803 in Iwamizawa, but it is not at a level where room revenue alone could support ¥2.7 billion worth of floor space. That is why, as we read it, the project chose an operating design that spreads the nature of its income across three layers, lodging (19 rooms), housing (18 units) and community use (hall, bathhouse, restaurant), while sharing staff and facilities.

From an operator’s perspective, three points are worth checking. First, room revenue is more sensitive to occupancy and room count than to rate. With 19 rooms, annual room revenue stays within a range of ¥26M–¥49M (at 50–70% occupancy), and the revenue lost from the 5 rooms (about ¥8.1M a year) is on a scale that 18 housing units at about ¥40,000 a month in rent can fill. Second, after reopening, the 19 rooms will be the only rooms in central Sunagawa bookable through those sites, and that scarcity of competing inventory translates into freedom in rate setting. Third, whether to put hotel and housing in the same building or in separate buildings turns on the serviced senior housing registration standards (floor area of 25 ㎡ or more, equipment, services) and the building-confirmation requirement for changes of use (over 200 ㎡). PARK SHIRO chose the separate-building model and secured the floor space by acquiring city-owned land. After the January 2027 reopening, how the rate for the 19 rooms and day-use of the bathhouse develop will provide concrete reference points for regional station-front hotels facing the same conditions.
