Osaka City’s special-zone minpaku (national strategic special-zone minpaku) will stop accepting new applications on May 29, 2026. The remaining options converge into a binary choice: the 180-day-cap Residential Accommodation Business (minpaku new law), or the year-round 365-day simplified lodging (kani-shukusho) under the Ryokan Business Act. Meanwhile, Japan’s nationwide vacant-home count has reached a record 9.00 million units (13.8%) (source: Ministry of Internal Affairs, 2023 Housing and Land Survey), bringing single-building (ittougashi) investments that convert old regional homes into lodging back into scope. This article quantifies license acquisition costs, vacancy rates and zoning, regional differences in fire and construction expenses, and the IRR of a 5-room single-building model across three cities: Kyoto, Osaka, and Naha.

From Three Options to Two – The License Hierarchy Revealed by the End of Special-Zone Minpaku

Japan’s lodging business licensing splits broadly into three categories: the Residential Accommodation Business Act (minpaku new law, 180-day annual cap), special-zone minpaku under the National Strategic Special Zones Act (minimum 2-night/3-day stay, no annual cap), and simplified lodging under the Ryokan Business Act (year-round 365-day operation). Special-zone minpaku is a unique framework available only in designated areas such as Osaka City, Ota Ward, and Chiba City, but a surge in neighbor complaints (Osaka City: 556 cases in 2024; 314 cases by July 2025) has led Osaka City to halt new applications on May 29, 2026, with certification processing ending June 30 of the same year (source: Travel Voice November 28, 2025 report, Osaka City official notice).

As a result, from June 2026 onward, investors newly entering the Osaka area effectively face a binary choice: minpaku new law (180-day cap) or simplified lodging (Ryokan Business Act). Since the annual-day ceiling of 180 vs. 365 days creates more than a 2x gap in NOI (Net Operating Income), for serious investors simplified lodging becomes the only viable structure going forward. Meanwhile, cumulative notifications under the Residential Accommodation Business Act reached 59,427 as of January 15, 2026, with 21,315 discontinued, leaving only 38,112 active registered dwellings (source: MLIT Minpaku Portal). This indicates that the 180-day cap constrains business viability, and approximately 36% have already exited. How distributed supply on the extension of the minpaku new law absorbs different price tiers and customer segments is explored in depth with case studies from Kyoto, Okinawa, and Tokyo in The Minpaku 10% Share Era: Which Price Tiers and Customer Segments Does Distributed Supply Absorb.

Vacant-Home Stock Depth and Regional Contrasts – Kyoto, Osaka, Naha Structural Comparison

The vacancy rates of the three cities stand in sharp contrast. Kyoto Prefecture stands at 13.15% (38th nationally, 180,400 vacant units), Osaka Prefecture at 14.3% (34th nationally, down 0.9pt from 15.2% in the previous survey), and Okinawa Prefecture at 9.4% (46th nationally, the second-lowest after Saitama Prefecture) (source: Ministry of Internal Affairs 2023 Housing and Land Survey, Okinawa Prefecture Statistics Division release). Okinawa’s continuing population growth keeps its vacant-home stock thin, with Naha City’s vacancy rate at just 9.7%.

Within Osaka City, Nishinari Ward has an exceptionally high vacancy rate of 25.92%. The Nishinari-Naniwa-Tennoji area, dense with aging nagaya (row-house) and terrace dwellings, ranks among the nation’s most promising candidate zones for single-building conversion in terms of stock depth. In Kyoto Prefecture, Miyazu City has the highest vacancy rate at 34.48% and abandoned-home rate of 18.68%, but tourism demand is distributed across the region, so the concentration of investment into central Kyoto (Shimogyo Ward, Higashiyama Ward) remains unchanged. Central Kyoto’s machiya stock, within MetroEngines Research’s tracking scope, totals 655 properties (averaging 1.4 rooms in scale), alongside 125 vacation rentals and 256 guesthouses – single-building types now exceed 1,000 properties in aggregate stock depth. The 2026 pipeline of new openings likewise shifts toward single-building and vacation rentals as the leading structure, organized from a self-catering x extended-stay compatibility angle in The 2026 New-Opening Lead Actor is “Single-Building & Vacation Rental”.

Actual Cost of Simplified Lodging License – Three Fire & Construction Boundaries

Actual costs to acquire a simplified lodging license vary significantly by property size and stair configuration. There are three major boundary conditions. First, the change-of-use confirmation application under the Building Standards Act. When gross floor area exceeds 200㎡, a building confirmation (change of use) application is required, and structural calculations and fire-resistance standards can trigger additional investments of several million yen. Because the 2019 revision raised the threshold from 100㎡ to 200㎡, compact single-building properties in the 150-200㎡ range can avoid this regulation (source: MLIT, various administrative-scrivener guides).

Second, fire-code equipment categories. Buildings classified as “Specified Single-Stairway Fire Prevention Object” (with only one staircase) face fire-equipment costs exceeding ¥2M, whereas “Specified Small-Scale Facilities” (under 300㎡ with multiple staircases) can be kept to around ¥0.4-0.5M. Wireless automatic fire alarms are permitted, enabling substantial cost compression. Third, application and administrative-scrivener fees run ¥0.3-0.6M as standard. Overall, for regional-city properties with 150-200㎡ gross area, 5 rooms, and multiple staircases, fire plus application total falls within a ¥0.8-2M range. Conversely, for older, narrow 3-story properties in central Tokyo that fall under the Specified Single-Stairway rule, costs can balloon past ¥3M.

Land Prices and Zoning – Boundary Conditions for Acquisition Cost and Renovation Feasibility

Central commercial-district public land prices differ across the three cities: Kyoto City Shimogyo Ward averages ¥1.882M/㎡ (YoY +9.30%), Osaka City averages ¥1.317M/㎡ (+8.46%), and Naha City’s commercial area averages ¥509.8k/㎡ (+7.06%) (source: MLIT Reiwa 8 Public Land Price Survey). In absolute land-price terms, Naha is the lowest – roughly one-quarter of Kyoto on a per-tsubo basis. However, Naha City has limited low-utilization land of sufficient scale, and its vacant-home stock depth trails Kyoto and Osaka, warranting caution.

From a zoning perspective, simplified lodging falls under the classification defined in Ryokan Business Act Article 2, so in principle it cannot open in Category 1 Low-Rise Residential Exclusive Zones or Industrial Exclusive Zones. Central Kyoto’s machiya-dense areas (Shimogyo, Higashiyama, Nakagyo Wards) mostly fall under Neighborhood Commercial, Commercial, or Semi-Industrial zones, so licensing barriers are relatively low. Osaka City’s Nishinari Ward nagaya-dense area mixes Category 2 Residential and Neighborhood Commercial zones, requiring case-by-case verification per property. The Naha City Makishi-Kokusai-dori area has broadly designated Commercial zoning, so zoning barriers are the lowest.

5-Room Single-Building Model: IRR Decomposition Across 3 Cities

This is the core quantitative analysis of this article. We set up a simplified lodging model of 150-200㎡ gross floor area, 5 rooms, single-building type, and estimate IRR (10-year holding assumption) across three cities. Assumed conditions: acquisition price – used machiya around Kyoto’s Shimogyo/Higashiyama ¥60-80M, nagaya in Osaka’s Nishinari/Naniwa ¥30-50M, detached houses in central Naha ¥30-45M. Renovation costs (structural reinforcement + interior + full equipment refresh) run ¥15-30M (regional cities are ~25-40% cheaper than Tokyo). License acquisition: ¥1-3M. Assumed ADRs reflect each market ADR and small-scale single-building actuals: Kyoto ¥35,000 / Osaka ¥22,000 / Naha ¥25,000. OCC is scenarioed in the 60-70% range.

As the table shows, first-year GOP yields are Kyoto 18.4% / Naha 19.1% / Osaka 16.9% – all three cities substantially exceed typical hotel investments (5-8%) in absolute terms. This reflects the characteristics of small-scale single-building lodging: fixed costs are thin, so room rate x occupancy translates directly to GOP. On a 10-year IRR basis, the leverage effect from relatively lower acquisition and renovation costs is larger in Osaka and Naha, producing a reversal structure where Osaka 12.4% and Naha 11.6% overtake Kyoto 9.8%. Kyoto has the greatest upside in rate potential, but the heavy acquisition principal slows capital turnover.

Subsidy Utilization Boundaries – Actual State of Lodging-Conversion Support in Kyoto & Naha

The three cities differ in the depth of subsidies for vacant-home utilization. Kyoto City operates the “Reiwa 7 Vacant Home Utilization and Distribution Subsidy,” with two menus: the “Building Utilization Subsidy” (directly usable for lodging conversion) and the “Site Utilization Subsidy” (used for demolition). Applying as a lodging operator narrows the eligible use cases (source: Kyoto City official site). Naha City operates the “Vacant Home Utilization Tourism Facility Development Subsidy,” providing a framework that partially subsidizes initial investment in lodging facilities (source: Subsidy Agent Okinawa Prefecture Naha City data). Osaka City has limited standing subsidies specifically targeting lodging conversion, so utilizing national-level “New Business Expansion Subsidy” and “Sustainability Subsidy” is common.

The realistic impact of subsidies runs in the tens to low millions of yen for license acquisition and fire equipment. Against a total investment scheme exceeding ¥60M, this amounts to only a few percentage points of downward push. However, combining the Sustainability Subsidy (¥2.0M cap) as working capital after license acquisition can bolster first-year cash flow. What matters is not inflating acquisition prices on the assumption of subsidies; the safe operating principle is treating subsidies as a “nice-to-have” bonus.

Sensitivity Analysis – ADR/OCC Fluctuations and Risk Scenarios

This estimate requires sensitivity analysis to see how much optimistic-vs-pessimistic swing it can absorb. The table below shows how IRR shifts for Osaka (the recommended case) when ADR and OCC vary.

Even in the worst pessimistic scenario (ADR -10%, OCC -5pt), 10-year IRR holds at 9.1%. This reflects the thin fixed-cost structure of small-scale single-building operations. Conversely, on the optimistic side, Osaka’s small single-building supply within MetroEngines Research’s tracking is extremely thin – 8 ryokan, 18 guesthouses, and 3 vacation rentals – so the halt of new special-zone minpaku supply may raise the scarcity value of legally 365-day-operable single-building properties.

Structural Comparison of Risks and Upsides Across 3 Cities

Investment Decision Summary – Three Actions During the Regulatory-Convergence Phase

First, the May 29, 2026 halt on new special-zone minpaku applications marks a turning point that eliminates the “last chance” of the regulatory menu for single-building entry in Osaka. Since new entrants going forward face only the simplified lodging option, reliably avoiding fire-equipment and building-confirmation boundaries (200㎡ and Specified Single-Stairway) becomes a necessary condition for investment success.

Second, in the side-by-side IRR comparison, Osaka (12.4%) leads as the recommended choice from a relative capital-efficiency standpoint. However, all three cities substantially exceed traditional hotel investment yields (5-8%) in absolute terms. The structure allows a choice among three patterns per risk tolerance: Kyoto for stable capital gains, Osaka for turnover-focused plays, and Naha for subsidy utilization plus land-price appreciation.

Third, this estimate stops at the GOP stage. Post-depreciation, borrowing-interest, and income-tax-adjusted take-home IRR will be lower. Additionally, renovation costs can move upward by 20-30% depending on structural survey results for used properties, so a due-diligence budget (roughly ¥1-2M for architect and administrative-scrivener fees) should always be reserved at acquisition time.
