After-School Day Services × Closed Schools — The Most Compatible Combination [2026 Edition]

The combination of after-school day services (hōkago-tō dei sabisu, hereafter "ASDS") and closed school buildings is described as the strongest fit for a clear structural reason.

Perfect Spatial Alignment

Running an ASDS operation requires several types of space:

• Activity rooms: Sufficient area for individual and group support programs
• Movement space: Wide-open floor area for sensory integration and physical therapy activities
• Outdoor activity space: Grounds for outdoor play, gardening, and excursions
• Vehicle access and parking: Drop-off/pick-up lanes and parking for transport vehicles

Compared with a typical closed school campus, these requirements map almost perfectly.

Finding a space with "wide indoor floor area" is typically the hardest part of setting up a new ASDS facility. At a closed school, it comes standard. Classrooms are built on uniform modular dimensions, making them highly adaptable for different program zones.

Location Independence Through Institutional Revenue

ASDS revenue is derived primarily from disability welfare service reimbursements (public funds), making it largely independent of foot traffic or consumer discretionary spending. Even in a depopulated area, a stable institutional income stream is achievable once a sufficient user base is established — a fundamentally different revenue profile from tourism, food service, or retail.

Since users are children residing in the surrounding community, a closed school in a rural area is naturally accessible to the local children it could serve.

The Psychological Fit of "Former School" Architecture

Many children using ASDS have difficulty attending regular school. Yet closed school buildings — with their familiar classroom layouts, gym ceilings, and open grounds — tend to be reassuring environments for children. The physical scale and character of a school building is well-suited to providing a space where children can explore and move freely.

ASDS reimbursement underwent significant restructuring in the FY2024 revision. The most important change was the introduction of a time-based classification system.

Shift to Time-Based Classification

Before the FY2024 revision, a flat per-session reimbursement applied regardless of service duration. Under the revised system, reimbursement is based on the length of service provision in three tiers.

Under the FY2024 revised schedule, ASDS reimbursement is structured in three time brackets — under 3 hours, 3–5 hours, and 5 hours or more — with different unit values for each.

The standard model — providing 3–5 hours of after-school support — generates approximately ¥10,000–14,000 per session.

Key Add-On Programs

The following supplementary reimbursements apply on top of base rates:

• Specialist support add-on: For employing physical therapists, occupational therapists, or speech-language pathologists
• Family support add-on: For providing consultation and training to parents and caregivers
• Transport add-on: 54–99 units per one-way trip
• Medical coordination add-on: High-value add-on for facilities serving medically complex children (iryōteki kea-ji)

For facilities leveraging the large space of a closed school to serve medically complex children, combining the specialist and medical coordination add-ons can substantially increase per-session revenue.

June 2026 Emergency Revision

The June 2026 emergency revision applied a base reimbursement reduction of approximately 1.8% to newly designated ASDS facilities only, in response to the continued rapid growth in the number of providers. Existing facilities are unaffected, but operators planning new openings must incorporate the revised rates into their financial models.

The following three scenarios model the monthly finances of a closed school-based ASDS facility with a capacity of 10 users.

Assumptions

• Capacity: 10 users
• Service duration: 3–5 hours (approximately 1,000–1,200 units per session)
• Regional classification: Standard (1 unit ≈ ¥10)
• Operating days per month: 20–22
• Transport add-on: 70 units one-way (140 units round-trip) applied

Scenario Comparison

Comparison: standard commercial lease (¥250,000/month)

Closed school reuse generates approximately ¥250,000 in additional monthly surplus at the standard utilization scenario — funds that can be directed toward wage improvements, program investment, or reserve building.

ASDS Facility Standards

To receive prefectural designation, a facility must meet the following minimum standards:

For 10 users, the training/activity room must be at least approximately 25 m². A standard classroom at a closed school (typically 60–70 m²) exceeds this requirement by a comfortable margin.

Key Renovation Work Items

The main renovation categories for converting a school to an ASDS facility are as follows.

Required

• Accessibility modifications: Accessible toilets (western-style, with grab bars), corridor width (≥90 cm), step removal, ramp installation
• Fire safety equipment: Updating or installing automatic fire alarm systems; sprinkler systems may be required depending on floor area
• Use-change permit: For floor areas exceeding 200 m², a use-change building permit application is required to reclassify from "school" to "special-use building"

Recommended

• HVAC system: School heating/cooling systems tend to be large and outdated; upgrades or additions are often needed
• Interior finishes: Wall and floor repairs; safety and hygiene standards must be met for child use
• Site works: Improving vehicle circulation for drop-off/pick-up, parking layout

Renovation Cost Estimates

Renovation costs for closed school conversions are generally estimated at 1/3 to 1/2 of new construction costs. Small-scale welfare facility conversions using 200–500 m² of the closed school typically involve renovation costs in the range of ¥8–20 million.

With the Social Welfare Facility Construction Subsidy (Ministry of Health, Labour and Welfare), the national government covers 1/2 and the prefecture covers 1/4 of eligible renovation costs — reducing the operator's share to as little as 1/4 of total renovation costs.

Nerima Ward, Tokyo — Child Development Support Center

In Nerima Ward, Tokyo, a closed school was repurposed as a child development support center, integrating multiple child support functions — including developmental day services — by leveraging the facility's original spatial configuration.

Common Success Factors Across ASDS Reuse Cases

Analysis of successful cases reveals the following shared characteristics:

1. Early relationship with the municipality: Securing a low-cost or rent-free arrangement through early and collaborative engagement with the school-owning municipality
2. Subsidy utilization: Limiting the operator's renovation cost share to approximately 1/4 through the Social Welfare Facility Construction Subsidy
3. Alignment with local needs: Proximity and referral relationships with nearby schools, special needs schools, and medical institutions as a source of users
4. Specialist staffing: Occupational therapists, speech-language pathologists, or physical therapists on staff to access add-on reimbursements
5. Outdoor and agricultural programming: Using the schoolyard or adjacent land for outdoor activities that enhance developmental support quality

Legal Entity Formation

Operating an ASDS facility requires a legal entity. Incorporated associations, NPOs, and social welfare corporations are all eligible, but differ in setup cost, timeline, and subsidy access.

For new entrants, NPO or incorporated association is the typical starting point, with transition to a social welfare corporation considered as the operation scales.

Prefectural Designation Application

Key documents required for the designation application include:

• Designation application form
• Corporate registration certificate
• Floor plans and photographs of the facility
• Staff roster, work schedules, and qualification certificates
• Operational regulations
• Financial plan

The process from application to designation typically takes 2–4 months. This should be planned in reverse from the desired opening date, accounting for renovation lead time.

Standard Timeline

1. Entity formation and preliminary site assessment: 1–3 months
2. Municipal negotiation and lease agreement: 2–4 months
3. Renovation design and construction: 3–6 months
4. Prefectural designation application: 2–4 months
5. Pre-opening preparation and staff hiring: 1–2 months

Total preparation time is typically approximately 1–2 years.
