DoubleTree by Hilton Naha Shuri Castle (ダブルツリーbyヒルトン那覇首里城; 333 rooms) in Shuri Yamagawa-cho, Naha, is changing hands at the operator level. When One REIT, Inc. (Oneリート投資法人) acquired the property in March 2026, its disclosure stated that “the current operator agreement ends in December 2026,” and Core Global Management Co., Ltd. (コアグローバルマネジメント) has announced that it will run the hotel from January 1, 2027 as “THE GRAND CASTLE NAHA SHURIJO by Hewitt Resort.” The same company only just relaunched the former Novotel Okinawa Naha (40 Matsukawa, Naha; 328 rooms) as “INFINISIS Naha Shurijo by Hewitt Resort” on July 31, 2026. As a result, the two large hotels within 2km of Shuri Castle, 661 rooms between them, are being consolidated under a single operator. This article confirms the timelines of both conversions against primary sources, takes an inventory of the Shuri-area room stock with duplicate listings merged, and uses Naha City’s estimated settled ADR together with the REIT’s disclosed yields and schedule to assess what a switch from a global flag to a domestic resort brand actually changes.

Room stock in this article covers lodging properties with 10 or more rooms (excluding leisure/love hotels) within a 2,000m radius of Shuri Castle. “Operating” means a sales price was observed on major booking sites in the latest three months (August–October 2026) (as of October 20, 2026; MetroEngines Research). The same property listed under different names was merged into a single property.

Bottom Line — Read Shuri’s Two Big Hotels as “Consolidation Under a Domestic Operator,” Not “Global Flags Leaving”

To state the conclusion first: what is happening around Shuri Castle is not a change in supply but a “consolidation of operations,” in which the operator and brand switch while the buildings and room counts stay the same. Merging duplicate listings, lodging within a 2km radius of Shuri Castle comes to 9 properties and 878 rooms, of which the two hotels to be run by Core Global Management (CGM) from January 2027, with 661 rooms, account for 75.3%. Limiting the count to the 5 operating properties (798 rooms) raises the share to 82.8%, meaning nearly all of the large-format rooms in Shuri will sit within one company’s sales network.

Meanwhile, the pricing foundation is moving up. Naha City’s estimated settled ADR (median) was ¥9,709 in September 2026, up 8.6% YoY, while Okinawa Prefecture as a whole was ¥12,040, up 10.0% (MetroEngines Research, N=144 / 515 properties). DoubleTree by Hilton Naha Shuri Castle’s estimated settled ADR in the same month was ¥18,879, 1.94 times the Naha City median and up 12.2% from a year earlier (¥16,824). The price position built over ten years of Hilton operation becomes the starting point after the 2027 conversion.

On the ownership side, One REIT acquired the property for ¥10,460 million at an appraisal NOI yield of 8.3%, and has disclosed a schedule premised on a ¥1.2bn renovation: “rebranded opening in May 2027, stabilized operations in January 2029.” It is also worth noting that the conversion coincides with a demand catalyst: the main hall (Seiden) of Shuri Castle holds its completion ceremony on November 22, 2026 and opens to the public from November 23.

Timeline of the Two Conversions — Only Facts Confirmed in Primary Sources

Both hotels covered here are conversions in which “the building stays the same and only the operator and brand change.” Arranging the primary sources we could confirm in chronological order gives the following. The Grand Castle (formerly Hotel Nikko Naha Grand Castle), opened in 1973, was relaunched as a DoubleTree by Hilton in 2016, and the table of 37 Japanese hotels in Hilton’s corporate overview (updated August 25, 2026) lists it as “Okinawa No.32, 333 rooms, 10 banquet rooms, 4 restaurants, 2016.” According to a July 2016 report by the Nikkan Kogyo Shimbun, the owner at the time was Ryukyu Hotel Resort Naha (琉球ホテルリゾート那覇), and Hilton came in under a management contract for the owned property.

Note that the building owner and contract structure on the INFINISIS side have not been disclosed. The Ryukyu Shimpo reported that the hotel “will continue operating under a new owner and operator,” but did not name the owner. On the DoubleTree side, One REIT discloses “rent structure: GOP-linked; operator: Hilton Worldwide Manage Limited,” and from 2027 CGM steps in as operator. The REIT’s disclosure goes only as far as the rent structure and does not describe the terms of the CGM contract itself, so this article does not speculate beyond what has been published.

From Hilton’s side, this ends a ten-year operating period that began in 2016. As of the overview, its Japanese portfolio comprised 9 brands and 37 hotels, with 7 hotels and 1,997 rooms in Okinawa (our tally of the 37-hotel table). Canopy by Hilton Okinawa Miyako Island Resort (306 rooms) opened in 2026, and the brand’s footprint in Okinawa is broadening toward resort destinations (Source: Hilton corporate overview, updated August 25, 2026). Within Naha City, DoubleTree by Hilton Naha (225 rooms), opened in 2012, continues to operate.

Room Stock Within 2km of Shuri Castle — 9 Properties, 878 Rooms After Merging; Two Hotels Hold 75%

Next, we take an inventory of rooms in the Shuri area. Listed stock within a 2,000m radius centered on Shuri Castle totals 12 properties and 1,846 rooms, but DoubleTree and its new name The Grand Castle, and the former Okinawa Miyako Hotel, Novotel Okinawa Naha and INFINISIS, are each listings of the same building. Merging the same property listed under different names leaves 9 properties and 878 rooms, of which the two converting hotels (661 rooms) account for 75.3%. Within a 1,000m radius there is only DoubleTree (333 rooms) plus an 18-room hostel, so in practice there is just one large hotel standing close to Shuri Castle.

Looking back year by year, rooms in this area rose from 732 in 2017 to 809 in 2018 (the Novotel opening after the Miyako Hotel renovation, plus the opening of one hostel and one business hotel), and have held flat at 837 since 2019 (two properties with 41 rooms whose opening years could not be confirmed are excluded from the trend). The two conversions in 2026 did not add a single room. Although the Shuri area sits next to Shuri Castle, the core of tourist demand, zoning constraints (discussed below) make it hard for new large-scale supply to enter, a structure in which the two existing large hotels tend to gain relative value.

Naha City’s Estimated Settled ADR and Shuri’s Price Tier — City Median ¥9,709; Shuri’s Large Hotels at About Twice That

First, the pricing foundation. Naha City’s estimated settled ADR (median) rose from ¥8,942 in September 2025 to ¥9,709 in September 2026, up 8.6% YoY. The annual peak was ¥14,216 in February 2026: in February, when pro baseball spring camps overlap with school trips and graduation trips, Naha’s business-hotel-heavy price tier is pushed up into the ¥14,000 range. Over the two years from September 2024 (¥7,730) the rise is 25.6%, moving in the same direction as Okinawa Prefecture overall (¥12,040 in September 2026, +10.0% YoY).

How far above this city median do the two Shuri hotels sit? DoubleTree by Hilton Naha Shuri Castle’s estimated settled ADR was ¥18,879 in September 2026, 1.94 times the Naha City median; ¥25,078 in February 2026 (¥20,294 a year earlier, +23.6%); and ¥21,337 in August 2026 (¥20,703, +3.1%). It stayed at 1.7 times the city median or more in all 21 months from January 2025 through September 2026, a stable price position for a full-service hotel with 10 banquet rooms and 4 restaurants. INFINISIS, converted on July 31, posted an estimated settled ADR of ¥10,066 in September 2026, starting out above the Naha City median (¥9,709) from the month right after its conversion.

We also looked at listed prices over the holiday weekend that includes the completion ceremony of Shuri Castle’s main hall (November 22) and its first public day (November 23). Listed prices as of October 19, 2026 (double occupancy, tax-included) were ¥52,000 at DoubleTree and ¥30,700 at INFINISIS for Saturday, November 21; ¥34,600 and ¥28,500 for Sunday the 22nd; and ¥31,400 and ¥22,000 for Monday the 23rd (national holiday). The gap between the two hotels is widest on Saturday and narrows toward the start of the week. These are listed prices for future dates and will change as check-in approaches. Naha-wide demand trends tied to the Shuri Castle reopening are covered in our separate article, “Shuri Castle Revival Lifts Naha Hotel Demand,” and are not the subject of this piece.

For reference, Naha City’s occupancy (estimated, based on OTA listed inventory) was 87.8% in September 2026 (179 properties / 15,059 rooms, based on listings on major booking sites), with business hotels at 87.7% (76 properties / 9,421 rooms) and resort hotels at 89.6% (17 properties / 2,298 rooms). These are estimates based on how inventory sold on OTAs is being absorbed and differ from each property’s actual occupancy, but they indicate that supply and demand in Naha were tight as of September.

Ownership and Contracts — Acquisition Price, Yields and Renovation Plan in One REIT’s Disclosure

On the ownership side of DoubleTree by Hilton Naha Shuri Castle, the most detailed disclosure comes from One REIT, Inc. (asset manager: Mizuho REIT Management). In March 2026 the REIT acquired five hotels and one office building for a combined ¥29,946 million at an average appraisal yield of 6.16%, and this property was the largest at ¥10,460 million (appraised value ¥11,500 million). The acquisition price per room is about ¥31.41 million, roughly in line with the weighted average of the REIT’s seven hotels (about ¥30.91 million; see our separate article “One REIT’s 7 Hotels Cost ¥30.9M a Room“).

What stands out is that the REIT discloses an “8.3% appraisal NOI yield” on the acquisition price and still expects 7.4% after adding ¥1.2bn of capital expenditure. It could buy at a higher yield than other March acquisitions such as Quintessa Hotel Fukuoka Hakata (4.55%) and Sapporo Susukino (5.05%) because the deal is positioned as an “upside-seeking investment” in a 53-year-old building involving an operator change; the REIT itself describes it as “a hotel with substantial room to improve profitability.” In the appraisal’s DCF assumptions, the occupancy index drops to 90 in Year 2 (the renovation year) and the RevPAR index dips to 96 before recovering to 117 in Year 3 and 124 in Year 4.

The ¥1.2bn renovation works out to about ¥3.6 million per room; combined with the acquisition price, total investment comes to ¥11.66bn, or about ¥35.01 million per room. With hotel construction costs in 2025 staying high at an all-structure average of ¥2.174 million per tsubo (steel frame ¥2.405 million per tsubo) according to MLIT’s Building Construction Starts statistics, raising rates through an operator switch and partial renovation of an existing building is more rational in terms of capital efficiency than building a new 333-room full-service hotel. The site conditions that make it hard for new large supply to enter the Shuri area also support this judgment.

What a Brand Conversion Changes — Distribution, Royalty Costs and Fee Rates in General Terms

When a hotel swaps a global flag for a domestic brand, what happens to the owner’s and operator’s P&L? Because individual contract terms are not disclosed, we lay out the general picture with sources. In its U.S. annual report (Form 10-K, FY2023), Hilton explains that under franchise contracts it receives “royalty fees based on a percentage of rooms revenue,” and under management contracts a “base management fee based on a percentage of total revenue” and an “incentive management fee based on operating profit,” and that it separately charges monthly “program fees” for marketing, reservation systems and quality assurance based on revenue or usage. Its loyalty program, Hilton Honors, has more than 260 million members (Source: Hilton corporate overview, updated August 25, 2026).

A benchmark for the total cost is HVS’s annual “U.S. Hotel Franchise Fee Guide” for the U.S. market. According to Hotels magazine’s coverage of the 2025 edition, total franchise costs were 9.6% of rooms revenue for economy brands and 12.9% for upscale brands, with a median of 12.5% for full-service hotels. Japanese contracts are not necessarily at these levels; we refer to them only as U.S. franchise-market benchmarks.

In short, a global flag is a mechanism for buying a global distribution network and member base with revenue-linked fees, while a domestic operator brand replaces those fees with the operator’s own sales capability and freedom of concept. Neither is inherently better; the choice depends on whether it fits the property’s demand mix. One REIT discloses that it “compared and examined multiple operators” for this property and chose CGM on three points: its track record of reviving older hotels, its experience running large banquet operations, and the scale benefits of its existing operations in Naha. For a property with banquet halls and a pool that serve lodging demand from pro sports teams and student groups, it is reasonable to read that an operator strong in group sales was valued as a revenue opportunity.

Checking the Hilltop Site — Zoning, Hazards and Land Prices Against MLIT Data

As a premise for investment, we check the site conditions. Checking the area around both sites in MLIT’s Real Estate Information Library (queried October 20, 2026), the zoning at DoubleTree’s (Shuri Yamagawa-cho) property coordinates is Category 1 Exclusively Low-Rise Residential (floor area ratio 100%, building coverage ratio 50%), with Category 2 Residential and Neighborhood Commercial zones (FAR 200%) scattered within 250m. INFINISIS (40 Matsukawa) likewise falls in a Category 1 Exclusively Low-Rise Residential zone, surrounded by Category 2 Residential, Quasi-Residential and Category 1 Mid/High-Rise Residential zones. Both are large high-rise buildings erected before the current zoning designations (DoubleTree has 22 floors plus a basement; INFINISIS has 15 floors), and building something of the same scale on the same sites would not be easy under current regulations. This is the basis for the scarcity of the existing large-format rooms.

On hazards, no tsunami or storm-surge inundation zones are designated around either site, and the Asato River flood inundation zone (maximum assumed scale) is confined to low ground about 220m below DoubleTree’s coordinates. In coastal Naha, where many sites sit at low elevation, the Shuri heights have an advantage against water damage. The flip side of the hilltop location is that landslide warning zones are designated on slopes about 80m from DoubleTree’s coordinates and about 170m from INFINISIS. The sites themselves are outside these zones, but maintenance of surrounding roads and retaining walls is an operational item to check.

On land prices, MLIT’s 2026 Official Land Price Publication shows the residential standard site in Shuri Yamagawa-cho at ¥118,000/㎡ (+2.6% YoY), three residential sites in Shuri Ishimine-cho at ¥146,000–¥168,000/㎡ (+3.1% to +5.7%), and the commercial site in Shuri Gibo-cho at ¥235,000/㎡ (+6.8%). These are moderate compared with commercial land in central Naha, making this a location where the value of using the existing buildings drives the investment decision more than the burden of land cost.

The Effect of One Operator Running 661 Rooms — Three Scenarios for Shuri

Finally, we sketch, within the bounds of published information, what may happen in Shuri when the two hotels and their 661 rooms come under the same operator. According to One REIT’s disclosure, CGM operated 31 properties with 4,388 rooms as of January 2026, and the Hewitt Resort brand has four properties: Hakodate, Nasu, Kita-Karuizawa and Naha. The company’s press release (June 2026) cites 35 properties in Japan, and Hewitt Resort Naha in Asato is already open in Naha. With the two Shuri hotels, the same operator will run three hotels within Naha City.

Restating these scenarios in numbers: against the Grand Castle’s total investment of ¥11.66bn, the REIT’s disclosed post-depreciation appraisal NOI yield of 5.5% (assuming the renovation) corresponds to annual post-depreciation NOI of about ¥640 million. That is about ¥1.93 million per room per year, assuming stabilized operations from January 2029. This figure is a simple estimate that merely multiplies the disclosed yield by total investment; an actual investment decision requires a detailed feasibility study.

Because this simple estimate depends on a single yield, we also check the range. The tables below show three scenarios that move the NOI yield on total investment of ¥11.66bn by ±1pt around the disclosed 7.4% as the base case, and a two-way grid of NOI yield and cap rate showing how far implied value sits above (or below) total investment. In the base case, annual NOI is about ¥863 million, or about ¥2.59 million per room, and applying the 7.5% cap rate back-calculated from the disclosures puts implied value roughly level with total investment (99%). A 1pt shortfall in NOI yield drops implied value to 85% of total investment, while a 1pt beat lifts it to 112%. The yield swing is driven mainly by how quickly ADR and occupancy recover after the renovation, and the dividing line is how much of the appraisal’s RevPAR index of 124 (Year 4) can be achieved.

Risk factors include a later rebranded opening due to construction changes (noted by the REIT itself), lower occupancy during renovation, price competition with business-hotel supply in Naha, and changes in airline seat capacity. Under the 2026 winter schedule, international seats at Naha are expected to increase by 242 per day (see our separate article “Winter 2026 Flights as Seats“), so together with the Shuri Castle reopening, demand-side catalysts are lining up. On the supply side, two existing buildings with 342 rooms are being converted in Naha’s Asahibashi area (see “Naha Asahibashi: 2 Building Conversions Add 342 Rooms“), and room supply that does not rely on new construction has become a trend in Naha.

Summary — The Signs Change but Room Counts Don’t, Which Is Why Consolidating Operations Matters

The two rebrandings in the Shuri Castle area, in July 2026 and January 2027, consolidate 661 large-format rooms within 2km (75.3% of 878 rooms after merging) under one operator without adding a single room. Naha City’s estimated settled ADR rose to ¥9,709 in September 2026 (+8.6% YoY), and Shuri’s large hotel has established a price tier about twice that level over ten years of Hilton operation. One REIT acquired the property for ¥10.46bn at an 8.3% appraisal NOI yield and, with a ¥1.2bn renovation and an operator switch, expects a RevPAR index of 124 in Year 4.

A switch from a global flag to a domestic brand is a shift from buying a global distribution network with revenue-linked fees to earning through the operator’s sales capability and freedom of concept. The Shuri area, where three conditions overlap — the reopening of Shuri Castle’s main hall, more international flights, and supply constraints from zoning — makes a clear case study for measuring whether such a conversion succeeds. Following the disclosed schedule of a rebranded opening in May 2027 and stabilized operations in January 2029, we will continue to track the price gap with the Naha City median and occupancy at the two hotels.
