Japan’s Ministry of Defense has divided all Self-Defense Force camps, bases and related sites into 283 districts and is preparing a “master plan” for consolidating and rebuilding more than 20,000 buildings. The FY2026 budget allocates approximately ¥886.2 billion (contract basis) to “facility resilience” — roughly 1.9 times the ¥474.0 billion of FY2023, in just three years. Rebuilding work is mostly carried out under multi-year contracts running two to three years, generating sustained weekday demand from contractors, designers and construction supervisors staying in the same town. This article takes the 20 camps and bases named in Ministry of Defense documents, counts the hotel rooms actively listed within a 10km radius of each, and quantifies where the capacity to absorb long-term business demand is thick and where it is thin.

The primary sources: 283 districts, 20,000+ buildings and ¥886.2 billion in FY2026

First, the provenance of the figures. The phrases “283 districts” and “more than 20,000 buildings” appear in the Ministry of Defense’s Progress and Budget for the Fundamental Reinforcement of Defense Capabilities: Overview of the FY2024 Budget Proposal as follows.

“Toward the consolidation and rebuilding of more than 20,000 Self-Defense Force facilities, contracts have been concluded for basic-policy formulation work (1 contract) and master-plan preparation work (15 contracts) covering all camps, bases and related sites (283 districts), and preparation has commenced.”
— Ministry of Defense, Overview of the FY2024 Budget Proposal (progress status, facility resilience)

The following Overview of the FY2025 Budget reports progress as “master plans for the consolidation and rebuilding of Self-Defense Force facilities are being prepared in sequence, and design and construction work has commenced,” explaining in a note that “all camps, bases and related sites are divided into 283 districts; the current condition of buildings and lifelines is surveyed and assessed, and a master plan is prepared covering structural reinforcement according to each facility’s function and importance, together with relocation and consolidation to secure separation distances.” In other words, the 283-district master plans are moving from the drafting stage into design and construction. Separately, the Ministry of Defense’s FY2023 administrative program review materials indicate that there are roughly 23,000 Self-Defense Force buildings nationwide, of which about 40% — 9,900 buildings — were built under the older seismic design standards.

The FY2026 amount, meanwhile, can be confirmed in the key items of Progress and Budget for the Fundamental Reinforcement of Defense Capabilities: Overview of the FY2026 Budget (April 8, 2026). “Facility resilience” comes to approximately ¥886.2 billion (approximately ¥878.4 billion excluding other fields), and the largest single line within it is “renewal of existing facilities” at ¥436.8 billion. The document describes this line as “promoting structural reinforcement of buildings and the relocation and consolidation of facilities, in order to add protective performance including countermeasures against ageing and earthquakes.”

The figure has risen four years running: ¥474.0 billion in FY2023, ¥631.3 billion in FY2024, ¥695.3 billion in FY2025 and approximately ¥886.2 billion in FY2026 — up about 27.5% on FY2025. The Defense Buildup Program sets a framework of roughly ¥4 trillion for “facility resilience” over five years (allocation table in the Overview of the FY2025 Budget), and the four-year total has already reached about ¥2.7 trillion. The documents state facility contract terms of “two to three years,” so the accumulating contract value means a growing number of sites where work continues across multiple years.

710 construction and 775 consultancy contracts — procurement spread across 10 bureaus

What matters for reading the geography of this demand is that the budget is not concentrated in the major cities. According to “Overview of FY2026 Projects,” presented by the Ministry of Defense’s Bureau of Defense Buildup Planning at a March 25, 2026 briefing with the Defense Facility Resilience Promotion Association, FY2026 planned procurement comes to 710 construction contracts and 775 construction consultancy contracts nationwide (both as published on that date, excluding ECI-method projects).

The largest construction workload is North Kanto with 100 contracts, followed by Chugoku-Shikoku with 87, Okinawa 82, Hokkaido 77, Tohoku 75 and South Kanto 75. Adding the Obihiro Defense Branch Office’s 25 contracts to the Hokkaido Bureau’s 77 gives 102 in Hokkaido alone. In construction consultancy, Okinawa stands out at 142 contracts, followed by South Kanto with 115 and Hokkaido with 95. Design and supervision work sends engineers to site ahead of, or alongside, construction, generating lodging demand on a different timetable from the construction contracts themselves.

The same document also names specific districts and scales as each regional defense bureau’s major projects. All involve buildings on the order of tens of thousands of square metres, built out over two to four years.

The document further lists the districts where the ECI method (in which the contractor provides technical input from the design stage) is applied to “optimization projects” that wholly renew ageing facilities: Camp Obihiro, Camp Asahikawa, Camp Sapporo, Camp Higashi-Chitose, Chitose Air Base, JMSDF Ominato District, Misawa Air Base, Hachinohe Air Base, Matsushima Air Base, Camp Sendai, Camp Jinmachi, Gifu Air Base, Komatsu Air Base, JMSDF Maizuru District, Miho Air Base, Hamamatsu Air Base, JMSDF Sasebo District, Camp Itami, Camp Zentsuji, JMSDF Kure District, Nyutabaru Air Base, Naha Air Base, JMSDF Naha Air Base, Kanoya Air Base, Camp Kengun, Kasuga Air Base, JASDF Hofu District, Komaki Air Base, Tsuiki Air Base, Hyakuri Air Base, Shimofusa Air Base, Iruma Air Base, Camp Asaka, Camp Nerima, Tateyama Air Base, JMSDF Yokosuka District, Atsugi Air Base and Camp Fukuoka. Technical-cooperation contracts covered 20 districts in FY2024, 4 districts in FY2025, and 13 districts are planned for FY2026.

How many rooms lie within 10km of the 20 districts

From the ECI-method districts we excluded those located in the major metropolitan areas and regional core cities (Sapporo, Sendai, Higashi-Chitose/Chitose, Gifu, Itami, Naha, Kengun, Kasuga, Komaki, Fukuoka, Shimofusa, Iruma, Asaka, Nerima, Yokosuka, Atsugi), leaving the 20 districts analysed here. Hamamatsu Air Base sits in Hamamatsu, a government-designated city, but is included because it lies outside the three largest metropolitan areas. Chitose was covered in an earlier article and is excluded here. For each district we count the lodging properties within a 10km radius of a representative point whose selling prices were confirmed listed between June and August 2026.

The 10km catchments of the 20 districts hold 791 properties and 39,422 rooms in total, of which business-category rooms account for 30,981 (79%). The spread, however, is wide. Hamamatsu Air Base has the thickest catchment at 6,824 rooms, with 31 properties of 100 rooms or more — enough for even a large construction team to be split across hotels. Camp Asahikawa (4,741 rooms), Camp Obihiro (3,850) and Hachinohe Air Base (3,037) also clear 3,000 rooms each, with deep, business-hotel-led capacity.

The middle tier comprises Camp Zentsuji (2,860 rooms), Komatsu Air Base (2,400), JMSDF Sasebo District (2,301) and Camp Jinmachi (1,917). The Zentsuji and Jinmachi catchments have a high share of ryokan and hot-spring inns, leaving the business-category share at only about 60% in each. To capture long-stay demand, setting up consecutive-night plans and breakfast and parking terms suited to business use is an opportunity for ryokan operators to build occupancy as well.

At the other end, five catchments fall below 1,000 rooms: JMSDF Ominato District (727 rooms), Nyutabaru Air Base (632), Tsuiki Air Base (544), Miho Air Base (422) and Hyakuri Air Base (102). Tateyama Air Base’s catchment has 1,426 rooms, but 126 of its 157 properties are small — whole-house rentals, pensions and guesthouses of 10 rooms or fewer — and most rooms sit in resort hotels and ryokan, leaving just 89 business-category rooms. It is a clear case of total room count alone failing to measure real capacity.

The weight of a long-stay team against business-category rooms (illustrative calculation)

How much lodging a construction period actually generates varies widely with the type of work, the schedule and the share of local hiring, and cannot be read directly from Ministry of Defense documents. As a yardstick for comparing the depth of business-category room stock, we therefore model the share of rooms taken if a fixed number of engineers and workers is stationed on weekdays.

Source: MetroEngines Research & Consulting (10km radius, business-category rooms, based on listings on major booking sites). The 50-room standing block is an assumption used for the calculation.

A standing block of 50 rooms is just 0.9% of business-category rooms in the Hamamatsu Air Base catchment and 1.2% around Camp Asahikawa — a scale that coexists comfortably with existing business-travel demand. In the Miho Air Base catchment, by contrast, it reaches 20.1%, and around Nyutabaru and Tsuiki roughly 10% each, meaning a single team would continuously hold about a tenth of weekday business-category rooms. In the Hyakuri (61.0%) and Tateyama (56.2%) catchments, business-category rooms are so few that teams are likely to widen their commuting radius into surrounding towns to secure beds.

Flexing the assumed headcount to 30 and 100 moves the share as follows. At 100 people, the share exceeds 10% in all nine catchments with fewer than 1,000 business-category rooms, reaches about 40% around Miho Air Base, and exceeds the entire business-category stock in the Hyakuri and Tateyama catchments.

Source: MetroEngines Research & Consulting (10km radius, business-category rooms, listings confirmed June–August 2026, based on listings on major booking sites). Headcounts are assumptions used for the calculation (one room per person, weekdays). Shading marks 20%+, 10%+ and 5%+.

What this shows is that the thinner the catchment, the more readily a single long-term contract becomes the foundation of occupancy. For corporate sales teams at existing hotels, monthly consecutive-night contracts and weekday-only flat-rate plans aimed at prime contractors, design firms and supervisors are a strong way to fill weekdays in the low season. For chain development teams pursuing long-stay demand in regional Japan, catchments where several of the named camps and bases sit close together — Misawa Air Base, Hachinohe Air Base and JMSDF Ominato District in Aomori, for example — offer the prospect of stacking demand from multiple projects.

Catchment ADR and weekday occupancy — the price band business demand rides on

Source: MetroEngines Research & Consulting (median across properties within 10km for which an estimated settled ADR was available, July 2026; catchments with N of 5 or more only)

July 2026 catchment ADR (median estimated settled ADR) sits broadly in the ¥5,000–¥8,000 range in the business-hotel-led districts. Levels such as JMSDF Kure District ¥5,900 (N=21), JASDF Hofu District ¥5,800 (N=8), Kanoya Air Base ¥5,500 (N=11) and Matsushima Air Base ¥5,100 (N=18) fit comfortably within typical long-assignment lodging allowances. Camp Asahikawa ¥12,100 (N=40) and Camp Obihiro ¥9,100 (N=43) run higher on summer leisure demand, while Tateyama Air Base ¥16,600 (N=33) is a catchment dominated by resort-type properties.

On a same-property year-on-year basis, the Misawa Air Base catchment rose +11.0% (N=14), JMSDF Ominato District +4.8% (N=8) and Tsuiki Air Base +3.7% (N=8), while Komatsu Air Base (-5.9%, N=29) and Miho Air Base (-5.4%, N=9) fell below the prior year. No clear imprint of the facility programme is yet readable in catchment ADR movements — which is to say that headroom on price remains ahead of construction ramping up.

On occupancy, we compared weekday stays (Monday–Thursday) with Saturday stays in July 2026 for the six cities where municipal-level estimated OCC is available.

Source: MetroEngines Research & Consulting (July 2026, municipal level; fixed cohort of properties listing at least 30% of total rooms on OTAs). An estimate based on OTA inventory, running higher than true room occupancy. Includes summer leisure demand.

In Obihiro (93.7% on weekdays), Asahikawa (95.8%) and Hachinohe (92.5%), weekday inventory clears at nearly the Saturday rate — summer season notwithstanding. Even in thick catchments, weekday availability is limited. Hosting a long-term team means securing blocks early in peak periods; for the hotel, that demand becomes a stable weekday base that widens pricing latitude. Sasebo (76.8% weekday, 88.3% Saturday) and Komatsu (75.1% weekday, 83.2% Saturday), by contrast, show a wide weekday–Saturday gap and clear weekday headroom. Komatsu, where an F-35 reception hangar of roughly 31,000m² is scheduled for completion in March 2030, and Sasebo, where construction continues in the Sakibe-Higashi district, are markets with substantial room for long-term business demand to lift weekday occupancy.

What this means for you — development, corporate sales and regional finance

For chain development teams pursuing long-stay demand in regional Japan.Public facility programmes are a demand source that accumulates project by project each fiscal year under the Defense Buildup Program. The programme sets a five-year envelope of roughly ¥4 trillion, and facility contract terms run two to three years. The Ominato, Nyutabaru, Tsuiki, Miho and Hyakuri catchments — each under 1,000 rooms within 10km — and Tateyama, with its thin business-category stock, leave room to consider mid-sized extended-stay formats with laundry and kitchenettes. Note, however, that construction timetables for individual districts are disclosed only narrowly outside the major projects named in the documents, so the timing and scale of work must be tracked through each regional defense bureau’s tender notices.

For corporate sales and revenue management teams at existing hotels.In ECI-method districts the contractor is involved from the design stage, so lodging demand can begin to build during design cooperation, before ground is broken. Proposing monthly consecutive-night contracts or weekday flat-rate blocks at the point where the prime contractor, design office and supervisor choose their local base locks in weekday occupancy in advance. In markets with a wide weekday–Saturday gap, such as Sasebo and Komatsu, such blocks translate directly into a weekday floor.

For regional banks and credit unions appraising regional projects.Room counts and business-category shares in these catchments are useful material for testing the demand assumptions behind new extended-stay projects and hotel renovation deals. Because construction demand is time-limited, the base case in a financial plan should extend to how the property hands off, after the work ends, to local business travel, leisure, or visitor demand tied to the units stationed nearby.

Conclusion

The Ministry of Defense has prepared master plans for consolidating and rebuilding Self-Defense Force facilities across 283 districts and more than 20,000 buildings, and is moving into design and construction. FY2026 “facility resilience” reaches approximately ¥886.2 billion, roughly 1.9 times the FY2023 level, and the planned 710 construction and 775 consultancy contracts are spread across 10 regional bureaus. Counting rooms within 10km of the 20 districts outside the major metropolitan areas gives 39,422 in total: four catchments — Hamamatsu, Asahikawa, Obihiro and Hachinohe — clear 3,000 rooms each, while five fall short of 1,000, from Hyakuri’s 102 to Ominato’s 727. The thinner the catchment, the more a single long-term contract becomes the foundation of occupancy. Long-term business demand created by public investment is a durable opportunity for regional hotels to build weekday occupancy.
