About an hour by car from central Osaka, across the Akashi Kaikyo Bridge, Awaji Island is seeing a rapid increase in the number of lodging facilities. According to MetroEngines Research, the number of properties listed on OTAs and similar channels across the island’s three cities — Awaji, Sumoto and Minamiawaji — rose from 295 in July 2025 to 407 in July 2026, a 38.0% increase in a single year. That is 1.38x. Normally, supply growth on that scale pushes rates down. Yet over the same period, estimated settled ADR rose in all three cities. This article breaks down that apparent contradiction across four dimensions — the composition of the new supply, land prices, supply-demand balance, and construction costs — and organizes the findings into a form usable for resort development investment decisions.

What the “1.4x” actually consists of — 189 properties, 524 rooms, 2.8 rooms each

The first point worth establishing is that growth in the number of listed properties is an entirely different thing from growth in the number of rooms. Within the scope MetroEngines Research observes, tallying newly listed lodging facilities in the three Awaji cities by year on an OTA-listing-confirmation basis, 189 properties appeared over the four years from 2023 to 2026. Their combined room count, however, comes to just 524 rooms — an average of 2.8 rooms per property.

The breakdown makes the reason obvious. Of those 189 properties, 175 are small, dispersed formats: vacation rentals, cottages, glamping sites and guesthouses. In 2023 that category covered 57 of 62 properties; in 2024, 47 of 50; in 2025, 43 of 46. What is happening on Awaji Island, in other words, is not a rush of large hotel construction but the accumulation of conversions — existing houses, old folk homes and idle land turned into lodging inventory in units of one to four rooms.

The same structure shows up in the island’s overall stock. The 490 properties confirmed to be operating across the three Awaji cities hold 4,334 rooms in total, but properties with four rooms or fewer account for 302 of them (61.6%) while contributing only 407 rooms (9.4% of the total). At the other end, just seven properties with 100 rooms or more hold 1,099 rooms (25.4%). Counted by property, the island is a collection of small lodgings; counted by rooms, it is a two-tier structure in which a small number of large properties control a quarter of supply.

Equally important is that the number of core hotel and ryokan properties has barely moved. Among the verified categories used to calculate estimated settled ADR (business hotels, city hotels, resort hotels, ryokan and capsule hotels), the property count went from 55 in July 2025 to 56 in July 2026 — a gain of one. While listed properties rose by 112, the island’s mainstays, the properties with banquet halls, large baths and food-and-beverage operations, were essentially unchanged.

Rates rose in all three cities — estimated settled ADR up 7.7% to 11.0%

So how did rates move? Comparing estimated settled ADR against the same period a year earlier, using only confirmed months (months whose actuals have settled), Awaji City went from ¥15,500 to ¥16,700 (+7.7%), Sumoto from ¥20,300 to ¥22,500 (+11.0%) and Minamiawaji from ¥19,000 to ¥20,700 (+8.7%). All three rose. The downward pressure on rates that a 38% jump in supply would imply has not appeared, at least not among the core property group.

One caveat matters here: the increase in listed price (the all-plan average) is very different from the increase in estimated settled ADR. Over the same period, listed price rose 17.2% in Awaji City, 35.7% in Sumoto and 15.9% in Minamiawaji — two to three times the pace of estimated settled ADR. That gap is mainly a mix effect. Whole-property vacation rentals show a high per-room published amount, so when large numbers of such properties join the listings, the all-plan average is automatically pushed up. Reading the surge in listed price as “island rates rose 30%” would be a mistake; the estimated settled ADR figure is the one closer to actual market conditions.

This pattern — rates hold because the composition of supply is different — is decisive as a premise for investment decisions. What one- to four-room vacation rentals mainly capture is demand for kitchens, group stays and car-based travel, a purchase motive quite different from that of ryokan and resort guests looking for a large communal bath and two meals included. Even on the same island, the two are not competing for price within a single inventory pool. The simple hypothesis that “rates fall in proportion to added supply” is therefore not supported, at least not by the past year of data.

The demand side — occupancy still has room to absorb more

Are rates rising because demand is strong, or is the supply side simply pricing higher? It is worth checking from the occupancy angle. Looking at estimated occupancy for July 2026 (OTA-listed-inventory basis) by category, resort hotels in Hyogo stood at 83.7% (42 properties, 2,221 rooms) and ryokan at 82.8% (189 properties, 3,580 rooms). In the same month, Okinawa resorts were at 91.7%, Hokkaido resorts at 88.4% and Shizuoka resorts at 84.2%.

Hyogo’s resort occupancy sits low among the major resort prefectures. That is less evidence of weakness than an indication that room remains to fill even while raising rates. There are eight points of headroom to reach Okinawa’s level, which would translate into close to a 10% gain in RevPAR on the same room count. Awaji Island is an hour by car from Osaka and just over 30 minutes from Kobe, so the physical constraints on drawing guests are smaller than at other resort destinations.

The booking curves show just how sharp the demand peaks are. For 3 May 2026, during Golden Week, the remaining-room ratio was already down to 14.3% at 45 days before check-in, and fell to 0.6% the day before. For 15 August, during Obon, it was 29.4% at 90 days out and 6.6% the day before. By contrast, a normal-season Saturday — 13 June — moved only from 34.8% at 90 days out to 11.0% the day before. Resort demand on Awaji Island, in other words, does not fill in steadily across the year; it concentrates sharply on consecutive holidays. That shape suggests the ceiling on peak-day pricing may not yet have been tested, and at the same time points to a revenue opportunity in product design that can lift occupancy during normal periods. How much the pace of sell-through varies by category across the prefecture as a whole is broken down by format in Hyogo Booking Curves: 3.6x Pickup Gap, Ryokan Sellout Rate 28.4%.

Location and land prices — a structure where rates rise but land does not

What makes Awaji Island unusual as an investment structure is that lodging rates are climbing while land prices are not following at all. Querying the 2026 official land price survey and prefectural land price survey (as of 1 January 2026) through the Ministry of Land, Infrastructure, Transport and Tourism’s Real Estate Information Library, commercial land in Iwaya, Awaji City was ¥51,300/㎡, down 0.2% year over year; commercial land in Honmachi, Sumoto was ¥76,000/㎡, down 2.3%; and commercial land in Fukura, Minamiawaji was ¥31,800/㎡, down 1.9%. On the residential side, Iwaya in Awaji City was ¥33,800/㎡ (+0.6%), Honmachi in Sumoto ¥47,000/㎡ (±0.0%) and Shiobidai in Minamiawaji ¥38,000/㎡ (±0.0%).

In Kyoto and the Osaka Bay area, competition for hotel sites has pushed land prices up, and that feeds through acquisition cost into a higher required ADR. On Awaji Island, that loop is not operating. Lodging rates are up 7% to 11% while land is flat to slightly down, so the improvement in earnings is not absorbed into land cost and instead stays with the investor. This is the core of a structure in which investment can pencil out even as supply grows.

On the regulatory side as well, the benchmark site in Iwaya, Awaji City sits within a non-demarcated city planning area with no designated use district. The floor area ratio applied to the benchmark site is 400% and the building coverage ratio 70%. There is little in the way of land-use obstacles to building a lodging facility, and for a low-rise resort the FAR would rarely be a binding constraint. Central Sumoto, by contrast, is designated as a commercial district (FAR 400%), which is where an urban-format hotel would fit. The procedure for reading development capacity from the combination of use district, FAR and land price is set out for major commercial markets in Hotel Development Capacity 2026: Zoning, FAR & Land Price in 5 Markets.

Positioning — the 25–70 room × ¥40,000s band is open

Plotting room count against rate for the 39 island properties where estimated settled ADR could be observed brings the market structure into focus. Twenty-one properties cluster in the zone of 15–80 rooms and ¥6,000–30,000, while the zone of 25–70 rooms and ¥40,000–70,000 contains not a single property. There is one property at 80 rooms or more and ¥35,000 or above, and three at 15–24 rooms and ¥35,000 or above.

Awaji Island, in short, has properties capable of commanding high rates, but all of them are small, at around 20 rooms; properties with scale sit in lower rate bands. Hotel New Awaji (ホテルニューアワジ) in Sumoto, which sustains the island’s top rate band at 117 rooms, is the exception to that split and demonstrates that combining scale with rate is possible in principle. From an operating-efficiency standpoint, the 25–70 room range is a scale that one general manager and a single food-and-beverage venue can run, and it spreads fixed costs per room more thinly than a property under 20 rooms. That this band is open is the most direct implication for investment on the island.

Notably, the extended-stay retreat “THE PASONA natureverse retreat,” which opened in Iwaya, Awaji City in June 2026 with 57 rooms all featuring natural hot spring baths, lands squarely in this WS 1 range. It is operated by Pasona Resort Inc. and designed by Shigeru Ban Architects, and its program is built around extended stays themed on preventive health, with food, exercise and sleep as its pillars (source: Pasona Resort Inc. official release). The company has also announced plans to relocate its Expo 2025 Osaka, Kansai pavilion exhibit to the “Yumebutai Sustainable Park” on Awaji Island and open it as a museum in autumn 2026. Because it opened so recently, the property is not included in this article’s rate tallies, but it represents a first answer to the open band.

Construction cost — the variable that accounts for over 90% of the investment

For development on Awaji Island, the bulk of acquisition cost is determined not by land but by construction. Dividing the planned construction cost for lodging-use buildings by floor area in e-Stat’s Building Construction Starts Statistics, the national average rose from ¥1.113 million per tsubo in 2017 to ¥1.955 million per tsubo in 2024 — a 75.7% increase in seven years. For Hyogo Prefecture alone the 2024 figure is ¥2.145 million per tsubo, but lodging-use construction starts within the prefecture number just 94 buildings and 33,329 ㎡ per year, a small base with large year-to-year swings, so the national average is used for the estimates here. How this level of construction cost is filtering opening plans nationwide is examined across the 2027–2029 pipeline in Construction +41% & Labor Crunch Erase Japan’s 2027-2029 Hotel Supply.

Working backwards to a viable acquisition cost per room

Building up total investment on these assumptions gives ¥153.9 million for land, ¥1,442.93 million for construction and ¥432.88 million for FF&E and related items — ¥2,029.7 million in total, or ¥50.74 million per room. What stands out is that land accounts for just 7.6% of the total. A land share that not uncommonly reaches 30% to 50% in central-city hotel development comes to less than a tenth on Awaji Island. On the 2024 basis, before factoring in construction inflation, the figure would be ¥42.29 million per room — meaning a two-year delay in completion creates a gap of ¥8.45 million per room, or ¥338 million across 40 rooms. Investment on this island is decided by groundbreaking timing, not by land price movements.

Sensitivity is shown across nine combinations of three ADR levels and three occupancy levels. The pessimistic case (ADR ¥38,000, occupancy 65%) yields an investment yield of 7.2%, the base case (ADR ¥45,000, occupancy 72%) 9.5%, and the optimistic case (ADR ¥52,000, occupancy 78%) 11.8% — a spread of 4.6 points.

Viewed from the opposite direction, against the base case GOP of ¥4.80 million per room (ADR ¥45,000, occupancy 72%), a 7% target yield implies a viable acquisition cost of up to ¥68.6 million per room, 8% implies ¥60.0 million and 9% implies ¥53.3 million. The assumed cost of ¥50.74 million falls within that range and sits marginally above the ¥48.0 million ceiling implied by a 10% target. In other words, on a 2028-completion basis a high-single-digit yield is within reach, but achieving double digits would require either restraining construction cost or building product strong enough to clear ADR ¥45,000.

The validity of that ¥45,000 ADR assumption also deserves a check. The top estimated settled ADR currently observed in the 25–70 room range is just under ¥40,000, so ¥45,000 sits a little over 10% above it. It is not a number reachable by extending existing product; it requires stacking up the elements that justify the rate — hot spring baths in guest rooms, extended-stay programs, food and beverage with destination appeal. Put the other way round, a property that can stack those elements is positioned to take the open band on its own.

Risk factors

Conclusion — do not misread the “1.4x”

It is a fact that the number of listed properties across the three Awaji cities rose from 295 to 407 in a single year. But most of that increase consists of small, dispersed properties of one to four rooms: the 189 properties newly listed over four years total 524 rooms, an average of 2.8 rooms each. The count of core hotel and ryokan properties rose by one, from 55 to 56. Over the same period, estimated settled ADR rose 7.7% to 11.0% across all three cities. Read the volume of supply without reading its composition, and you will misjudge this island’s supply-demand balance.

What stands out as an investment structure is that rates are rising while land is not. Commercial land in the 2026 official survey was flat to slightly down in all three cities, and land accounts for only 7.6% of total investment. Turn that around and what decides success or failure on this island is construction cost and groundbreaking timing, not competition for sites. The 25–70 room range that supports operating efficiency remains open at premium rates, and occupancy still has roughly eight points of headroom relative to Okinawa. For investors in the Kansai region, Awaji Island is a market that has yet to fully price in its distance advantage as “an island an hour from Osaka.”
