This article analyzes the facility's design philosophy as a starting point, then examines the structural logic of the "Kosodatenoeki" (childcare station) network that Nagaoka City expanded to 13 locations. The analysis extracts structural lessons applicable to other municipalities as a sustainable model for repurposing unused public facility spaces for childcare support.
Design Philosophy and Three Principles
Nagaoka City's unique design principles of resident nursery staff, free admission, and all-weather functionality, with their background rationale
Designing 'Reasons to Visit'
The design philosophy of Kosodatenoeki Senshu is not about "building a facility" but about "creating a place that young families want to visit every day." Three design principles derived from reverse-engineering this objective support sustained facility utilization.
Principle 1: Resident Nursery Staff
"Tekuteku" has nursery professionals on site, allowing visitors to consult about childcare without appointments. Regular sessions with public health nurses, midwives, and dental hygienists are also available.
The significance of this design lies in spatially integrating "play space" and "consultation services." Traditionally, childcare consultations required visiting city offices or health centers — the act of "going for consultation" itself posed a barrier. By embedding consultation functions within the play space, a natural pathway of "consulting while visiting for play" emerges.
Principle 2: Free Admission
Admission is entirely free. While designed considering the economic burden on young families, being free directly increases visit frequency — "anyone can come casually, as many times as they like."
With paid facilities, the decision "is it worth paying the admission fee today?" occurs each time. Free facilities reduce this psychological cost to zero, facilitating establishment as everyday infrastructure.
Principle 3: All-Weather Functionality
Nagaoka City is one of Japan's heaviest snowfall areas, with extended periods when outdoor play is restricted in winter. "Tekuteku" features covered plaza areas enabling active play regardless of rain or snow.
This all-weather design is an inevitable design decision driven by Nagaoka's climate conditions, simultaneously contributing to facility utilization rates by enabling "365-day availability." Municipalities with different climate conditions would need corresponding adaptations — "extreme heat countermeasures" or "typhoon safety provisions" — tailored to local climate challenges.
Facility Composition and Spatial Design
Three-area composition of 'Maru,' 'Sankaku,' and 'Shikaku' and visitor flow design
The indoor facility of "Tekuteku" consists of three areas named after geometric shapes: "Maru" (circle), "Sankaku" (triangle), and "Shikaku" (square).
| Area | Function | Target |
|---|---|---|
| Maru | Play area for small children including infants | 0-2 years and guardians |
| Sankaku | Lunch and snack space | All ages |
| Shikaku | Physical activity area with play equipment | Toddlers to school-age |
This three-area composition spatially separates needs based on developmental stages and activity types while completing the experience within a single facility. Quiet spaces where parents of infants can relax and active spaces where children over three can move freely are arranged without mutual interference.
Outdoors, approximately 20,000 square meters of parkland extends with maintained pathways allowing free movement between indoor and outdoor areas. This "seamless indoor-outdoor" design extends facility usage time and promotes repeat visits.
Childcare Station Network Expansion
Phased expansion from Tekuteku to Gungun, Chibikko Hiroba, Sukusuku, and others across 13 locations
From 1 Location to 13
Following the success of "Tekuteku," Nagaoka City expanded "Kosodatenoeki" across the city. The noteworthy achievement is building a sustainable expansion model that leverages existing public facility spaces rather than depending on new construction.
Key Facility Deployment
Nagaoka City publishes thirteen Kosodatenoeki, and the official name of each one names the building it sits in.
| Common name | Name published by Nagaoka City | Siting type |
|---|---|---|
| Tekuteku | Kosodatenoeki Senshu "Tekuteku" | Park-integrated |
| Chibikko Hiroba | Kosodatenoeki Chibikko Hiroba | Downtown |
| Gungun | Kosodatenoeki Nagaoka Citizen Disaster Prevention Center "Gungun" | Co-located with a disaster facility |
| Sukusuku | Kosodatenoeki Tochio "Sukusuku" | Former municipality area |
Structure of the Expansion Model
Notably, facilities after "Tekuteku" were not necessarily new construction:
- Gungun: As its name says, it sits inside the Nagaoka Citizen Disaster Prevention Center
- Sukusuku: Located in the area of the former city of Tochio
- Floor numbers and street addresses could not be confirmed in Nagaoka City publications, so they are not given here
This approach of "inserting" childcare support functions into existing public facilities is a sustainable expansion model that increases facility count while controlling new construction costs. Repurposing unused spaces in facilities that "are not operating at full capacity" — such as disaster prevention centers and industry exchange centers — also contributes to improving overall public facility utilization rates.
Sustainable Operations Structure
Fiscal burden of free facilities, operational sustainability, user satisfaction, and policy effects
Fiscal Burden of Free Facilities
Operating 13 locations with resident nursery staff and free admission entails a certain fiscal burden. However, Nagaoka City continues this investment based on structural judgments:
Promoting settlement of young families: Building a brand as "a city great for raising children" contributes to stemming population outflow and attracting young families. Nagaoka City is known within Niigata Prefecture for its childcare support quality, with childcare stations functioning as a deciding factor for relocation decisions.
Preventive welfare function: An environment where daily childcare consultations with resident nursery professionals are available contributes to preventing escalation of parenting stress and child abuse. Compared to the cost of intervention after problems become severe, this represents rational preventive investment.
Multi-use of facilities: Placement within existing public facilities creates benefits of improved utilization rates and shared maintenance costs. Making the first floor of a disaster prevention center into a childcare station increases overall visitor numbers, enhancing the facility's raison d'etre.
Operating Structure
Childcare station operations are directly managed by Nagaoka City, not privately contracted. Nursery staff personnel costs are covered by the city's general fund. This direct management model holds advantages in unified service quality and public accountability, while also carrying risk of fiscal pressure.
Implications for Other Municipalities
Conditions for reproducing the welfare repurposing model for public facilities
Challenge-First, Not Facility-First Design
Nagaoka City's childcare station model does not aim to "build impressive facilities." Facility form, location, and operational methods were determined by reverse-engineering from the challenge of "creating systems that prevent young families from becoming isolated." This "challenge-first" design philosophy is the most important lesson.
Conditions for Reproduction
1. Clear Commitment from Mayor and Council
Expanding childcare support facilities to 13 locations requires long-term fiscal commitment. The key is whether the mayor and council can share the recognition that "childcare support is urban infrastructure" for preventive investments that are difficult to measure with short-term cost-benefit analysis.
2. Inventory of Existing Public Facilities
New construction like "Tekuteku" is expensive. Starting with existing facility repurposing types like Gungun or Chibikko Hiroba allows testing effects while controlling initial investment. The starting point is scrutinizing the municipality's comprehensive public facility management plan to identify repurposable unused spaces.
3. Precise Understanding of Regional Needs
Nagaoka City's "all-weather" design was derived from heavy snowfall climate conditions — directly imitating it elsewhere would be meaningless. Understanding "what young families in this specific area struggle with" and designing responsive solutions is essential.
Nagaoka City's childcare station model demonstrates the value of connecting public facilities with welfare functions. By changing the "usage" of existing public spaces rather than building new structures, infrastructure supporting young families' daily lives can be established. What matters is not facility grandeur but designing "reasons to visit every day" — nursery professionals are present, it's free to use, weather doesn't matter — three principles from the user's perspective.

What to do next
In the order you can act on them, within the week you read this.
| # | What to do | Where | Rough effort |
|---|---|---|---|
| 1 | Establish the project cost. Above 1 billion yen including construction, or 100 million a year for operations alone, changes what priority review covers | Budget team | Half a day |
| 2 | Check whether your organisation has a priority review regulation. If not, follow the Cabinet Office guidelines | Planning team | One week |
| 3 | Sort facilities by whether user charges are levied, or could be. If they can be, operating rights come into view | Each department | One week |
| 4 | Use steps 1–3 to narrow the method: Park-PFI for urban parks, a small concession for other idle facilities | Departmental decision | — |
| 5 | Pick the first project and run market sounding. Do not advance every facility at once | Private operators | 2–3 months |
Step 1 takes half a day and decides whether review is mandatory at all.
