In Kumamoto Prefecture, more than half of the lodging room stock sits in the five wards of Kumamoto City, where business hotels form the core. Meanwhile, the onsen areas spread inside and outside the Aso outer caldera rim — Kurokawa, Oguni, Minamiaso and Uchinomaki — are lined with small, high-rate inns. In this article, we average MetroEngines Research & Consulting’s estimated settled ADR by municipality over the 12 finalized months (October 2025–September 2026), and overlay the rate tiers of 43 municipalities (Kumamoto City by ward) with segment mix, supply, demand and location factors to identify which price bands and areas in the prefecture leave an investment gap.

This article is the Kumamoto edition of our prefectural investment map series (including Oita, Kochi and Ishikawa). The impact on rates and inventory of the July 28, 2026 Reiwa 8 Kumamoto Earthquake and of the Kyushu Fukko Ouenwari travel subsidy (Kumamoto allocation), which began on October 1, is tracked chronologically in our earlier piece “Kurokawa Onsen after the earthquake: Minamioguni has 63 listings and September ADR up 8.7% YoY.” Here we focus on the structure of the municipal tiers and treat the post-earthquake months with notes. Supply around the semiconductor fabs (Kikuyo Town, Ozu Town and Koshi City) overlaps with “Hotel markets in four semiconductor hubs 2026,” so this article only positions those towns within the prefectural hierarchy.

Prefecture-wide estimated settled ADR is ¥10,600, −0.1% YoY — autumn recovered what the earthquake summer lost

First, the prefecture-wide level. The 12-month average estimated settled ADR (October 2025–September 2026) was ¥10,600, essentially unchanged (−0.1%) from ¥10,600 in the preceding 12 months (October 2024–September 2025). The monthly property count ranged from 366 to 404, with no month in which the sample was substantially replaced. The 12 months were far from flat, however: it is more accurate to read the result as strong autumn/winter months offsetting a weak early summer and summer.

By month, the peaks are November and January. November 2025 came in at ¥11,900, +5.5% over the prior-year month (¥11,200), and January 2026 at ¥11,800 (+8.3%), as autumn foliage and New Year demand pushed rates up. In contrast, June 2026 was ¥9,000 (−6.0%) and July ¥9,200 (−10.0%), well below the prior year. The impact of the Reiwa 8 Kumamoto Earthquake on July 28 (seismic intensity 7 in Uki City and Hikawa Town) appeared in the last days of July and in August, which held at ¥10,800 (−5.0%). Even so, September recovered to ¥11,000 (+9.1%), above the prior year. Prefecture-wide rates thus kept their seasonal pattern — up in the autumn/winter travel season, softer in early summer — while recovering from the post-earthquake dip in little more than a month. The day-by-day recovery from the quake is tracked over 46 days in Kumamoto hotels after 190,000 cancelled guest-nights: measuring the Kurokawa Onsen and Aso recovery over 46 days.

Comparing 12-month averages by segment, ryokan stood at ¥17,000 (−3.2% YoY), resort hotels at ¥14,300 (+11.1%), city hotels at ¥9,900 (+2.3%), and business hotels at ¥7,100 (+3.3%). Behind the flat-looking prefectural median lies movement in opposite directions: ryokan, which account for more than half of covered properties, edged down, while business and city hotels serving corporate demand rose.

Rate tiers across 43 municipalities — from Minamioguni at ¥29,800 to Hikawa at ¥5,100

Next, we break the figure down by municipality. Ranking the 43 municipalities with a calculable estimated settled ADR (Kumamoto City by its 5 wards) by 12-month average, rates in the prefecture split into four broad tiers. At the top are the onsen and highland areas inside and outside the Aso outer rim: Minamioguni Town (Kurokawa Onsen) at ¥29,800 (42–47 estimated properties), Minamiaso Village at ¥25,500, Tamana City (Tamana Onsen) at ¥21,100, Yamaga City (Yamaga and Hirayama Onsen) at ¥19,600, Aso City (Uchinomaki Onsen and others) at ¥19,200, and Oguni Town (Waita Onsen area) at ¥17,100. The second tier is a mid-rate band of Kamiamakusa City at ¥13,500, Kumamoto City’s Kita Ward at ¥13,200 (Ueki Onsen) and Minamata City at ¥10,100. The third tier is the capital’s business and tourism core, with Chuo Ward at ¥8,600 (55–60 estimated properties), Ozu Town at ¥8,300, Amakusa City at ¥8,200, Nishi Ward at ¥8,200 and Kikuchi City at ¥8,100, all in the ¥8,000s. The fourth tier consists of value-oriented hubs, including Kikuyo Town at ¥7,300, Arao City at ¥7,200, Hitoyoshi City at ¥6,900, Yatsushiro City at ¥6,400 and Uki City at ¥5,700.

Note, however, that many rural municipalities have only 1–2 estimated properties, so a single property can swing the figure substantially. Nishihara Village’s ¥101,200 reflects 1–2 high-end whole-house rental properties, and the same applies to Ubuyama Village (¥31,200), Misato Town and Takamori Town. In the table below, municipalities with 2 or fewer estimated properties, or without a full 12 months of data, are therefore marked as “reference only.” Year over year, most onsen areas were positive — Aso City +12.0%, Tamana City +8.1%, Minamioguni Town +7.6%, Minamata City +7.7% — while Oguni Town (−8.9%), Ozu Town (−6.0%), Kikuyo Town (−6.7%) and Kita Ward (−4.3%) were negative; around the semiconductor fabs, supply ran ahead of demand with the large openings of 2025–2026, and that shows in rates.

Narrowing to the 23 municipalities with 3 or more estimated properties, rate stability also differs. Over the 12 months, Minamioguni ranged ¥25,100–32,200 (max/min 1.29x), Chuo Ward ¥7,700–10,400 (1.36x), and Yatsushiro ¥6,100–6,600 (1.08x): the thicker the corporate demand, the narrower the swing. By contrast, Tamana ranged ¥15,900–25,700 (1.61x) and Minamata ¥7,100–12,200 (1.73x), with rates moving sharply with seasons and events. From an investment perspective, municipalities with narrow swings make fixed-cost recovery easier to plan, while in municipalities with wide swings, capturing peak-season demand directly determines annual revenue.

Mapping the rate tiers — high rates in and around the Aso rim, business hubs on the Kumamoto Plain and in Yatsushiro and Hitoyoshi

Placing municipal estimated settled ADR on a map makes the geography of rates clear. The high-rate tier runs along the northern slopes of the Aso outer rim in the northeast (Minamioguni Town, Oguni Town, Ubuyama Village) and inside the caldera to the south (Aso City, Minamiaso Village, Takamori Town). To the west, business-hub rate bands line the Kumamoto Plain (Kumamoto City’s 5 wards, Ozu Town, Kikuyo Town, Koshi City), the Ariake Sea coast (Tamana City, Arao City), the Yatsushiro Sea coast (Yatsushiro City, Minamata City) and the Kuma River basin (Hitoyoshi City). Across the Ariake Sea, Amakusa (Amakusa City, Kamiamakusa City, Reihoku Town) splits in character even within the islands: Kamiamakusa at ¥13,500 versus Amakusa at ¥8,200.

Breaking it down by segment — 5,259 business-hotel rooms in Kumamoto City’s 5 wards, small dispersed ryokan elsewhere

Behind the rate tiers lie differences in segment mix. Aggregating the September 2026 OCC-estimated properties (a fixed cohort whose OTA allotment is at least 30% of total rooms, based on major booking-site listings) by municipality and segment, Kumamoto City’s 5 wards account for 58 properties and 7,100 rooms — 55.9% of the prefecture’s 284 properties and 12,706 rooms (the municipal breakdown covers the top 21 municipalities by rooms, 12,316 rooms). Chuo Ward alone has 39 properties and 5,538 rooms, and business hotels across the 5 wards total 5,259 rooms. Chuo Ward’s rate settles at ¥8,600, below the prefectural median, because this thick stock of business hotels forms the median.

Outside the city, the picture reverses. In Minamioguni Town, 28 of 30 properties (390 of 429 rooms) are ryokan; in Aso City, 10 of 21 properties (396 of 773 rooms); in Yamaga City, 15 of 17 properties (255 of 364 rooms). Ryokan of 10–40 rooms each, scattered across these areas, form the high-rate tier. On the other hand, there are also business-hub towns outside the city: in Ozu Town, business hotels make up 6 of 7 properties (712 of 766 rooms), and in Arao City 2 of 4 properties (295 of 428 rooms). Kumamoto’s “rural” areas thus have two faces: small, dispersed onsen ryokan, and large business hotels located near factories and transport nodes.

The nature of supply — +39.6% in 9 years within 5km of central Kumamoto, +93% within 3km of the semiconductor fab

Supply is moving fast. Rooms within a 5km radius centered on Torichosuji grew from 64 properties / 7,168 rooms in 2017 to 85 properties / 10,009 rooms in 2026, up 39.6% in 9 years (7 properties / 451 rooms with unconfirmed opening years are excluded). The biggest jump came between 2021 (8,149 rooms) and 2022 (9,100 rooms), +951 rooms in a single year, and 2026 added another 510 rooms year over year to reach 85 properties / 10,009 rooms. The listing-based stock is 108 properties / 11,651 rooms, of which 76 properties / 9,760 rooms are operating properties with selling prices confirmed in the last 3 months. By size on a listing basis, 101–200-room properties number 30 (4,643 rooms) and 201+-room properties 16 (3,982 rooms): mid-to-large properties of 101+ rooms hold more than 70% of rooms.

Growth around the semiconductor fab is even steeper. Rooms within a 3km radius of Kikuyo Town (around TSMC) went from 7 properties / 772 rooms in 2017–2024 to 9 properties / 1,184 rooms in 2025 and 12 properties / 1,493 rooms in 2026, up 93% in 2 years. By contrast, the 3km radius of Kurokawa Onsen has stayed nearly unchanged for 9 years at 34–35 properties / 659–674 rooms, and the 3km radius of Uchinomaki Onsen in Aso City edged down from 15 properties / 599 rooms to 14 properties / 581 rooms; onsen supply has not moved. With supply fixed in the onsen areas at the top of the rate hierarchy and piling up in the business hubs at the bottom, this structure works to maintain the rate gap within the prefecture going forward.

Counting new openings on a confirmed-OTA-listing basis, 37 properties / 831 rooms opened in the prefecture in 2025, and 70 properties / 1,515 rooms by late October 2026. The large ones are Toyoko Inn Kumamoto Airport (208 rooms) and Super Hotel Premier Aso Kumamoto Airport (203 rooms) in June 2025; Onyado Nono Kumamoto (191 rooms, Chuo Ward) in August 2025; Workers Hotel Kumamoto Ozu (202 rooms, Ozu Town) in February 2026; Tabino Hotel Aso Kumamoto Airport (213 rooms) in April; Via Inn Prime Kumamoto (Hibari no Yu) (232 rooms, Nishi Ward, in front of Kumamoto Station) in July; and Hotel Amanek Kumamoto (176 rooms, Chuo Ward) in October — concentrated around the airport and fabs, and around Kumamoto Station and the city center. Kamenoyu by HATAGO INN (Higashi Ward), reopening under a new brand with 134 rooms in November, is a conversion of an existing building and not a net addition. Outside the city, notable openings include La Vista Minamiaso (90 rooms) in October, TAOYA Aso (59 rooms) in July, and HOTEL R9 The Yard properties (42–54 rooms) in Kamiamakusa City, Yamaga City and Ozu Town.

Announced plans for 2027 and beyond include the tentatively named Sanco Inn Grande Kumamoto (140 rooms, slated for autumn 2027) in Shimotori 2-chome, Chuo Ward; a Toyoko Inn slated for April 2027 in front of Shin-Tamana Station on the Shinkansen in Tamana City; and a site agreement under which Livemax will open an 11-story hotel on the west side of the former racecourse site in Arao City in spring 2028. In September 2025, the Kumamoto Nichinichi Shimbun reported that at least 4 properties totaling about 800 rooms would open or were scheduled to open in central Kumamoto City by 2027. These are based on building plans and announcements and are not included in the listing-based counts.

Supply and demand — September 2026 estimated OCC of 88.0%, second only to Fukuoka in Kyushu

We compare market tightness using estimated OCC. Kumamoto stood at 88.0% in September 2026 (284 properties / 12,706 rooms, based on major booking-site listings), second to Fukuoka at 88.3% (381 properties / 28,935 rooms) and above Saga (80.3%), Oita (78.8%), Miyazaki (78.4%), Nagasaki (77.2%) and Kagoshima (71.4%). August was 89.6% (312 properties / 13,262 rooms), level with Fukuoka, having risen through the summer from 77.5% in June and 80.7% in July. The high estimated OCC in post-earthquake August reflects the fact that, even as tourist cancellations were being reported, business-oriented inventory was filled: business hotels at 95.4% (59 properties / 7,399 rooms) and city hotels at 95.1%. Stays related to recovery and relief may have contributed, but the breakdown cannot be identified from this article’s data. The wide gap between business-hotel and ryokan OCC is also examined by segment in Kumamoto lodging shows a 15-point gap by segment — business 95%, ryokan 78%, and where the travel subsidy works.

By segment in September, business hotels were at 91.8% (58 properties / 7,123 rooms), city hotels at 93.0%, ryokan at 83.4% (137 properties / 2,675 rooms) and resort hotels at 79.4%. Rural ryokan rose from 78.7% in August to 83.4% in September, consistent with bookings for October and beyond moving ahead of the subsidy’s reservation opening (September 15). By municipality in September, Chuo Ward was 93.0% (39 properties / 5,538 rooms), Nishi Ward 92.6%, Kikuchi City 87.6%, Kamiamakusa City 87.4%, Oguni Town 85.8%, Yamaga City 85.3%, Aso City 80.7%, Minamioguni Town 79.1% and Minamiaso Village 69.2%: corporate demand in the capital is highest, while onsen areas fall in the 70–80% range.

Looking at how bookings build up on the booking curve, the first day and the middle of a holiday period fill differently. Respect for the Aged Day, Monday September 21, 2026 (a public holiday), fell in the middle of a long holiday combined with the Autumnal Equinox (the 23rd); estimated OCC was 77.1% at LT45, 86.5% at LT30, 94.0% at LT14 and 99.0% at LT1, nearly full. Saturday October 10, the first day of the Sports Day three-day weekend, started lower at 65.1% at LT45 but rose to 90.7% at LT14 and 96.9% at LT1. Friday August 14 (Obon), a little over two weeks after the earthquake, rose more gently than the two holiday dates, from 71.3% at LT45 to 90.4% at LT1. Common to all three dates is a 6–12-point fill between LT30 and LT14, making 2–4 weeks before the stay the window in which rates are set for many properties in the prefecture.

Pinpointing the gaps — the ¥12,000–18,000 band outside Kumamoto City has 1,064 rooms, and 38% of Obon dates sold out 30+ days ahead

Here we use inventory movements during peak periods to find price bands that sell out early yet have limited rooms. We look at two periods — Obon (4 nights, August 13–16, 2026) and Golden Week (4 nights, May 2–5, 2026) — both of which have passed with final results. Among properties with inventory data whose OTA allotment is at least 30% of total rooms (452 properties for Obon, 386 for GW), those with a calculable estimated settled ADR — 305 properties / 14,373 rooms for Obon and 262 properties / 12,940 rooms for GW — were divided into five price bands by each property’s 12-month average ADR. Note that the four Obon nights fell about two weeks after the earthquake, so they reflect inventory after cancellations and resales.

Outside Kumamoto City, the ¥12,000–18,000 band has 36 properties / 1,064 rooms — more rooms per property than the ¥18,000–30,000 band (56 properties / 977 rooms) or ¥30,000+ (45 properties / 577 rooms), yet a thin total. This band reached sell-out on every date across the four Obon nights (144 property-dates), and 38.2% of those dates hit zero remaining rooms 30+ days before the stay. In the same rural areas, the comparable share was 30.9% for ¥18,000–30,000, 32.2% for ¥30,000+ and 24.7% for ¥8,000–12,000, making the ¥12,000–18,000 band the fastest. In GW as well, 32.7% of dates in the rural ¥12,000–18,000 band reached sell-out, far above the ¥18,000–30,000 band (13.0%), ¥30,000+ (5.4%) and ¥8,000–12,000 (19.7%). High-rate ryokan keep inventory even in peak season, while the mid-priced band just below them fills first.

In Kumamoto City’s 5 wards, the ¥12,000–18,000 band has 16 properties / 1,976 rooms; it reached sell-out on every Obon date (64 property-dates), with 21.9% of dates reaching zero 30+ days ahead. The ¥8,000–12,000 band (21 properties / 3,146 rooms) also sold out on every date, but only 21.4% sold out 30+ days ahead, and under ¥8,000 (24 properties / 2,732 rooms) the figures were 95.8% and 15.6%: the higher the band, the earlier it fills. The ¥18,000+ bands hold just 3 properties / 23 rooms in the city, and in GW too, 35.0% of dates in the ¥12,000–18,000 band reached sell-out (¥8,000–12,000: 38.8%; under ¥8,000: 36.5%). The city’s upper bands do not show up in the sell-out statistics simply because the supply to absorb that demand does not exist.

Positioning within 5km of central Kumamoto — 1 property / 203 rooms at ¥18,000+, 3,991 rooms in the ¥8,000–12,000 band

We verify the capital’s gap property by property. Plotting the 67 operating properties / 9,446 rooms within a 5km radius of Torichosuji with a calculable estimated settled ADR by rooms × ADR, 27 properties / 3,991 rooms sit in the ¥8,000–12,000 band, 26 properties / 3,005 rooms under ¥8,000, and 13 properties / 2,247 rooms in the ¥12,000–18,000 band, while only one property — THE BLOSSOM KUMAMOTO (203 rooms, ¥21,000) — is at ¥18,000+. Segment medians are ¥8,100 for 49 business hotels, ¥13,500 for 11 city hotels and ¥9,900 for 4 ryokan. Large business hotels, mainly those opened in 2019–2022 — Candeo Hotels Kumamoto Shinshigai (カンデオホテルズ熊本新市街, 380 rooms, ¥13,700), Dormy Inn Kumamoto (ドーミーイン熊本, 290 rooms, ¥12,300; completed in 2008), Hotel Lef Kumamoto by Vessel Hotels (レフ熊本 by ベッセルホテルズ, 229 rooms, ¥12,500) and Daiwa Roynet Hotel Kumamoto Ginzadori PREMIER (ダイワロイネットホテル熊本銀座通り PREMIER, 180 rooms, ¥13,900) — form the ¥12,000–14,000 band, with Hotel Nikko Kumamoto (ホテル日航熊本, 191 rooms, ¥15,600) and Kumamoto Hotel Castle (熊本ホテルキャッスル, 179 rooms, ¥14,400) positioned above them.

This distribution shows that Kumamoto City’s upper end “tops out at ¥14,000–16,000.” Foreign guest-nights in Kumamoto Prefecture reached 1.763 million in 2025 (+19.8% YoY, Japan Tourism Agency preliminary figures), a record for the second consecutive year, and Kumamoto City alone exceeded 1 million for the first time. Kumamoto City is a market where increased Taiwan flights overlap with long-term semiconductor-related business trips. Combined with the fact that the ¥12,000–18,000 band sold out on every Obon date and posted the highest sell-out rate in the city during GW, there is room to place supply in the ¥18,000–30,000 upper band.

Listed REITs hold 5 properties / 850 rooms in Kumamoto City — acquisition price per room of ¥6.4–40.6 million

We check the market’s position in the investment market through properties held by listed hotel REITs. Among the domestic holdings of seven hotel-focused and diversified REITs — Ichigo Hotel REIT (いちごホテルリート投資法人, 3463), Invincible Investment Corporation (インヴィンシブル投資法人, 8963), Nippon Hotel & Residential Investment Corporation (日本ホテル＆レジデンシャル投資法人, 3472), Japan Hotel REIT (ジャパン・ホテル・リート投資法人, 8985), Hoshino Resorts REIT (星野リゾート・リート投資法人, 3287), Mori Trust REIT (森トラストリート投資法人, 8961) and Kasumigaseki Hotel REIT (霞ヶ関ホテルリート投資法人, 401A) — Kumamoto Prefecture accounts for 5 properties / 850 rooms, all in Kumamoto City (ownership master as of October 19, 2026, N=300 properties). Total acquisition price is ¥14,721 million.

Per-room acquisition prices are highest for the most recent two years: fav Kumamoto (fav 熊本, 67 rooms, ¥2,720 million), acquired by Kasumigaseki Hotel REIT in August 2025, at ¥40.6 million, and Hotel MyStays Kumamoto Riverside (ホテルマイステイズ熊本 リバーサイド, 194 rooms, ¥6,831 million), acquired by Invincible in July 2024, at ¥35.2 million. Nest Hotel Kumamoto (ネストホテル熊本, 201 rooms, ¥2,220 million), acquired by Ichigo Hotel REIT in April 2019, comes to ¥11.0 million; Japan Hotel REIT’s Dormy Inn Kumamoto (291 rooms, ¥2,334 million) to ¥8.0 million; and Comfort Inn Kumamoto Miyuki Fueda (コンフォートイン 熊本御幸笛田, 97 rooms, ¥616 million), acquired by Hoshino Resorts REIT in May 2014, to ¥6.4 million — a more than sixfold spread in per-room price depending on acquisition timing. Japan Hotel REIT does not disclose property-level acquisition dates in its portfolio list, so it is excluded from the acquisition-year comparison.

Location assessment — comparing 4 locations by residents, employment and land prices

Finally, we compare representative locations of the rate tiers by location factors. Within a 1.5km radius of central Kumamoto (Torichosuji) live 54,632 residents (2020 census basis), with a projected decline of only −4.0% by 2040. Within a 1km radius there are 51,810 employees, 22.0% of them in office-type industries, giving a thick base of corporate demand as a Kyushu prefectural capital. The average commercial land price in Chuo Ward in the official land price survey (as of January 1, 2026) was ¥552,625/㎡ (+6.17% YoY), up 9.4% in five years from ¥504,956 in 2021. Note that Kumamoto City has levied an accommodation tax (¥200 per person per night) since July 1, 2026; the scope and timing of taxation within the prefecture are summarized in Kumamoto’s accommodation tax applies only in Kumamoto City at ¥200 per person per night — no prefectural tax, effective July 2026, Ozu Town from December 2027.

Within a 1.5km radius of Kikuyo Town (around TSMC) live 9,284 residents, with a projected +8.8% by 2040 — an exceptional growth location within the prefecture. Kikuyo’s average commercial land price is ¥140,000/㎡ (+12.0% YoY) and neighboring Ozu Town’s is ¥104,000/㎡ (+8.9%), 2.43x and 2.17x their 2021 levels respectively; land prices have run ahead. Hotel rates (Kikuyo ¥7,300, Ozu ¥8,300, both down YoY) have not kept pace with land prices, indicating a gap between land cost and room rates.

Within a 1.5km radius live 585 residents at Kurokawa Onsen (Minamioguni Town) and 4,163 at Uchinomaki Onsen in Aso City; Uchinomaki’s 2040 projection is −29.3% with an aging ratio of 42.5%, a thin population base. Minamioguni’s benchmark land price (all-use average) is ¥9,633/㎡ (−0.38% YoY) and Aso City’s commercial land (benchmark land price) is ¥24,000/㎡ (+0.84%): land prices are flat. Onsen areas are markets sustained by visitor demand rather than residents or workers, and the ratio of hotel rates (Minamioguni ¥29,800, Aso ¥19,200) to land prices is the reverse of the capital’s. Kumamoto has also experienced seismic intensity 7 earthquakes in April 2016 and July 2026, making seismic performance and business continuity planning a common precondition for location assessment at all four locations.

Investment gaps — Kumamoto City’s upper band and the rural mid-price band

Overlaying the segment, supply, demand and location data above, the prefecture’s stock is thick in “Kumamoto City’s ¥8,000–14,000 business band” and “the rural ¥18,000+ onsen ryokan band,” with two gaps between and above them.

Summary

Lodging rates in Kumamoto Prefecture split into four tiers: a high-rate onsen/highland tier inside and outside the Aso outer rim (Minamioguni ¥29,800, Minamiaso ¥25,500, Tamana ¥21,100, Aso ¥19,200); a mid-rate tier in Amakusa and Ueki (Kamiamakusa ¥13,500, Kita Ward ¥13,200); a business-core tier in the capital and at factory/transport nodes (Chuo Ward ¥8,600, Ozu ¥8,300, Amakusa ¥8,200); and value-oriented hubs along the Kuma River and Yatsushiro Sea (Hitoyoshi ¥6,900, Yatsushiro ¥6,400). The prefecture-wide 12-month average of ¥10,600 matched the prior-year period, but underneath, segments moved in opposite directions: ryokan −3.2%, resorts +11.1%, business hotels +3.3%.

Supply is piling up in business hubs — +39.6% in 9 years within 5km of central Kumamoto and +93% in 2 years within 3km of the semiconductor fab — while onsen areas are virtually unchanged. On demand, estimated OCC in September 2026 was 88.0%, second only to Fukuoka in Kyushu, with Chuo Ward reaching 93.0%. By segment and price band, the ¥18,000+ band within 5km of central Kumamoto is just 1 property / 203 rooms (2.1%), while the ¥12,000–18,000 band sold out on every Obon date. Outside the city, the ¥12,000–18,000 band is thin at 36 properties / 1,064 rooms, and 38.2% of its Obon dates sold out 30+ days ahead — the earliest of any band. As investment approaches, adding upper-tier supply in Kumamoto City through acquisition/renovation in the city center or 120–200-room new builds, and building or renovating mid-priced properties of 10–30 rooms outside the city, are each consistent with the data.
