The case for reinvesting in hotels and ryokan at Kaike Onsen (皆生温泉) in Yonago, Tottori, is getting clearer. Within a 1km radius of the hot-spring town centre, MetroEngines Research found 21 properties with 932 rooms that showed bookable prices in the last three months, and it has observed no new openings since 2022. Yet the estimated settled ADR (median) of 19 properties in the same radius reached about ¥14,000 in September 2026, up 11.2% year on year. This article lays that combination — rising rates with no new supply — over the site conditions (zoning, land prices and inundation scenarios) to assess whether the reinvestment opportunity lies in renovation or in redevelopment.

The room stock in this article covers lodging properties with 10 or more rooms (excluding leisure/love hotels) within a 1,000m radius of Kaike Onsen. “Active” means a property whose selling prices were observed on major booking sites in the last three months (September–November 2026). As of November 3, 2026; compiled by MetroEngines Research.

Nine Years of Supply — 23 to 22 Properties Since 2017, Flat Since 2022

Start with supply. Counting properties at each year-end (limited to those with a known opening year), the 1km radius went from 23 properties and 991 rooms in 2017 to 22 properties and 968 rooms in 2026. The only additions were small ryokan (10–32 rooms) that opened in 2018, 2019 and 2021, and neither the property count nor the room count has moved since 2022. Room stock in the area has stayed at almost the same level for nine years.

Meanwhile, the listed total is 32 properties and 1,148 rooms, of which 21 properties and 932 rooms showed selling prices in the last three months. Most of the 11-property, 216-room difference consists of ryokan with 50 rooms or fewer; the reasons vary — some sell through channels other than the major booking sites, others are reconsidering how they operate. From an investment standpoint, the gap signals that the area contains candidates for business succession or turnkey acquisition that can make use of existing buildings and licences. How licences carry over under each acquisition structure is covered in Ryokan M&A: 3 Deal Structures and License Succession.

Location — A Hot-Spring Town Along Yumigahama Beach, Zoned Commercial at 400% FAR

On the map, most properties cluster in a band a few hundred metres from the shoreline. Overlaying the zoning data from MLIT’s Real Estate Information Library on each property’s coordinates shows that 28 of the 32 listed properties (1,046 rooms) sit in a commercial zone (FAR 400%, building coverage 80%). Today’s properties are mostly 30–100 rooms, so many sites may still have unused floor-area capacity. From a regulatory standpoint, it is a location where rebuilding to add rooms or amenities is relatively easy to consider.

Land Prices — Residential Up 3.9% in Six Years, Commercial Flat Three Years Running

Land acquisition cost is the first factor to bite in a reinvestment decision. The official land price (chika koji) standard site “Yonago-13” (Kaike Onsen 2-chome, residential) rose from ¥38,800/㎡ in 2020 to ¥40,300/㎡ in 2026, up 3.9% over six years. By contrast, the prefectural land price survey (kijun chika) benchmark “Yonago 5-6” (Kaike 5-chome, commercial) fell from ¥48,000/㎡ in 2020 to ¥46,800/㎡ in 2023, and has been flat for three straight years from 2024 to 2026. Commercial land settling below ¥50,000 per square metre makes the entry cost easier to read for buyers acquiring with land.

Inundation Scenarios — Tsunami Mostly 0.5–1m; Build It Into Redevelopment Design

For a seaside hot-spring town, inundation scenarios help decide between renovation and redevelopment. Overlaying Tottori Prefecture’s tsunami inundation scenario (2018) on the coordinates of the 32 listed properties, the largest group — 576 rooms — sits in the 0.5m-to-under-1m zone. Only 19 rooms are in the 1m-to-under-3m zone, and 277 rooms are outside the scenario area. For river flooding, almost the entire radius falls within the Hino River flood inundation zone (maximum assumed scale): 977 rooms are in the 0.5m-to-under-3m depth rank (including one property / 33 rooms that overlaps the 3m-to-under-5m rank), and 171 rooms are under 0.5m.

At most properties, the assumed depth is roughly at ground-floor level. That suggests the risk can be handled through design: moving switchgear, kitchens and plant rooms to upper floors in a renovation, or, in a rebuild, using the ground floor for the lobby or parking and putting guest rooms on the second floor and above. Because it also affects insurance premiums and loan terms, pre-acquisition due diligence should check each building’s ground elevation and equipment layout.

Rates — 1km Radius Est. Settled ADR ¥14,000 in September, ~1.8x Yonago City

Next, the demand side: rates. Yonago City’s estimated settled ADR was about ¥7,800 in September 2026 (N=44 properties), up 16.0% from about ¥6,700 a year earlier. October was about ¥8,300, up 11.1% year on year, so the rise was not a one-month blip. Because Yonago City includes many business hotels around Yonago Station, the hot-spring town sits well above the city-wide level. Narrowing to the 19 properties (905 rooms) within 1km that can be compared with the prior year, the median estimated settled ADR was ¥14,000 in September (prior year ¥12,600, +11.2%) and ¥14,700 in October (prior year ¥13,400, +10.0%). Ten of the 19 were above their prior-year level.

The winter outlook can only be read from listings at the time of the survey. Yonago City’s January 2027 estimate, based on a listing snapshot, is about ¥9,900 (N=39 properties), and the median of the 19 properties within 1km is about ¥16,100 — both above September levels. Winter after the opening of the Matsuba crab season is when rates tend to rise at San’in hot-spring resorts, and the town has the same seasonal peak. These figures, however, reflect selling prices currently listed and will change as check-in dates approach.

Within Tottori — The Gap to Misasa’s ¥17,000 Shows Kaike’s Rate Headroom

Lined up against Tottori’s main hot-spring areas and cities, Kaike Onsen’s position becomes clear. In September 2026 the estimated settled ADR was about ¥17,000 in Misasa Town, home to Misasa Onsen (N=19 properties); about ¥9,900 in Yurihama Town, home to Hawai and Togo Onsen (N=9); about ¥8,700 in Tottori City (N=37); and about ¥8,700 for the prefecture as a whole (N=152). Kaike’s 1km radius at about ¥14,000 is well above the prefecture, but short of Misasa. That a hot-spring resort in the same prefecture can sustain such rates suggests Kaike, too, has room to lift rates with a well-crafted product. The price hierarchy of Tottori’s municipalities and hot-spring areas is analysed in detail in Tottori’s 3-Tier Hotel Market.

Demand — Tottori Ryokan and Resorts at 84–90% Est. OCC in September–October

Whether rising rates are backed by demand should be checked from the occupancy side. Tottori Prefecture’s estimated OCC (based on OTA listed inventory) for ryokan was 84.5% in September 2026 (44 properties / 1,025 rooms, based on major booking-site listings) and 88.6% in October (53 properties / 1,472 rooms). Resort hotels ran slightly above ryokan at 87.1% in September (7 properties / 505 rooms) and 89.8% in October (10 properties / 696 rooms). Occupancy thus stayed high from the August summer-holiday period (ryokan 85.3%) into autumn.

Note that this estimated OCC is based on the take-up of inventory sold on OTAs. It does not match a property’s overall occupancy, but the fact that Tottori’s ryokan and resorts sold through more than 80% of that inventory in autumn is evidence that demand has not thinned even as rates rose.

Positioning — No Property at 30–60 Rooms × ¥20,000–30,000

The most concrete pointer for an investment decision is the distribution of size and rate. Plotting the 19 properties within 1km that have an estimated settled ADR by room count and September–October average ADR, six are below ¥10,000 and ten are at ¥10,000–20,000. Above that, one is at ¥20,000–30,000 and two are at ¥30,000 or more, leaving the middle layer thin. In the 30–60-room size band in particular, not a single property sits in the ¥20,000–30,000 range.

WS1 sits squarely between the crowded tier and the high-end tier. Given Misasa Town’s median of ¥17,000, a Kaike product aiming at ¥20,000+ would be in the top price band even among Tottori’s hot-spring resorts. Converting some rooms at an existing 30–60-room ryokan to rooms with private open-air baths, and selling a two-tier mix of premium and standard rooms, is likely the realistic option — reachable with less capital than a rebuild.

Guest Reviews — Properties Praised for In-Room Open-Air Baths Anchor Kaike’s Top Price Band

Guest reviews offer clues to products that can lift rates. In guest reviews analysed with NLP by the HotelBank Editorial Team (last 24 months, November 2024 to October 2026), five of the top 10 Tottori properties by positive mentions of rooms with private open-air baths were in Kaike Onsen. In first place, Kaike Yugetsu (皆生游月) had 261 of its 1,524 reviews speak positively about its rooms with open-air baths. Comments such as “every room has its own open-air hot-spring bath” and “sweeping views of the Sea of Japan from the room and the open-air bath” stood out, and there were also 297 positive mentions of the view.

Combining sea-view rooms with hot-spring bathing is a strength unique to Kaike that inland Misasa Onsen lacks. Kaike Yugetsu, opened in 2019, has turned that strength into a room-level product and carries the area’s top price band. Existing ryokan could also lift rates on the same criteria through phased renovation — for example, adding private open-air baths to sea-facing rooms first.

Vintage and Reinvestment — 48% of the 932 Active Rooms Opened in the 1970s or Earlier

The distribution of opening decades helps gauge renovation timing. Of the 21 active properties, 10 properties with 444 rooms opened in the 1970s or earlier — 47.6% of rooms. Five properties with 258 rooms opened in the 2000s or later. Opening year marks when the business started and may not match the building’s completion year, but it is safe to say that close to half the rooms in the area are in buildings that have been through several equipment-renewal cycles.

Next, a simple estimate of the rate uplift from renovation. Assuming a 35-room ryokan, close to the scale of WS1, we calculated how much annual room revenue would increase given an uplift in estimated settled ADR and an assumed occupancy rate.

We extended the two cases into three scenarios — downside, mid and upside — and a sensitivity table of ADR uplift × occupancy. The mid case (ADR +¥6,000, 65% occupancy, full-year assumption) yields an increment of about ¥49.8M, the downside case about ¥21.1M and the upside case about ¥86.2M. Note that the estimate holds occupancy constant before and after renovation, and excludes any gain or loss from renovation changing occupancy itself. When estimating the payback period on construction cost, the numerator should be this increment less any increase in operating costs.

Construction cost and revenue lost during a renovation closure need to be estimated separately. Even so, if the uplift reaches ¥6,000, the calculation points to an increase in room revenue on the order of ¥50M a year. Rebuilding is worth considering given the spare floor-area capacity, but once inundation-resilient design and rising construction costs are factored in, renovating existing buildings to capture rate headroom first is probably the realistic path for most properties.

Conclusion — In an Onsen Town With No New Supply, the Opportunity Is Renovation That Lifts Rates a Step

In sum, three conditions support reinvestment at Kaike Onsen. First, supply within the 1km radius has been almost flat for nine years, with no new openings observed since 2022. Second, the area’s estimated settled ADR rose 11.2% year on year in September, and Tottori’s ryokan and resorts ran at estimated OCC in the high 80s in autumn. Third, there is no property in the 30–60 rooms × ¥20,000–30,000 band, and the area’s highly rated strengths — in-room open-air baths and sea views — can be used to target it.

On location, the commercial zoning at 400% FAR gives flexibility for redevelopment, while tsunami and flood inundation scenarios are mostly around ground-floor level, a range that equipment placement can handle. For ryokan revitalisation funds, regional banks and business-succession buyers, it is an area where reinvestment can proceed in stages — renovating active properties as well as turnkey acquisitions and successions among the 11 properties / 216 rooms with no observable selling prices.
