How a Student Club's Playbook Can Fix Municipal Digital Friction

どうも〜おかむーです！

• Three-line summary:

- A Cabinet Office report (2025) shows 197 services already use the My Number (マイナ) Portal API — but municipalities still struggle with day-to-day admin friction.

- From my time leading the university startup circle P&D, I learned how to motivate unpaid builders and ship simple, useful flows fast.

- Combine that practice with modular MyNa API microservices, civic hackathons, and UX-first admin tools to dramatically cut municipal workload and raise citizen uptake.

結論

Local governments can stop reinventing the wheel: build a shared, composable marketplace of My Number Portal-based microservices, backed by civic hackathons and admin-first SDKs. This reduces repetitive administrative work, accelerates adoption of the 197-plus existing MyNa API services (Cabinet Office, 2025), and makes public services actually usable for citizens and staff.

Look, administrative work is famously full of small, repetitive tasks — someone even wrote about how daily admin is often tedious and procedural (see discussions on administrative work). At the same time, the Cabinet Office report from 2025 makes an important point: there are already 197 services using the My Number Portal API, and provider lists show APIs for health insurance, PMH, notification delivery and more. The raw plumbing exists, but municipalities struggle to stitch it into day-to-day operations and citizen UX.

This hits close to home for me. At Kyushu Institute of Technology I ran a student startup circle called Planning and Development (P&D). We had zero budget, a pile of unpaid students, and massive motivation problems to solve — how do you get people to build, ship, and care when money isn't the lever? I learned to break problems into tiny, testable pieces, run short sprints, and craft onboarding that makes participation trivial. That playbook turned out to be powerful.

I also built consumer products that forced me to think about real human behavior — like my app “5-hour only Cinderella Time.” In early tests, two friends who joined as unpaid testers ended up matching and later getting married. The lesson: if you design flows that reduce friction and respect human habits, people will actually use them.

So here's a concrete, actionable policy + tech stack idea for municipalities:

1) Build a Municipal Microservices Marketplace

- Publish a catalog of pre-built, audited microservices that wrap specific MyNa APIs (health insurance check, document pre-fill, eligibility lookup, notification delivery).

- Each microservice ships with a small front-end widget and a minimal admin panel so clerks can toggle it on without calling a contractor.

2) Admin-first SDKs and Templates

- Provide SDKs that implement common workflows (welfare application, child care subsidy, business permits) using the available MyNa APIs (period-linkage, PMH, etc.).

- Include accessibility-ready UI components so municipalities don’t need designers to launch.

3) Civic Hackathons + Participation Credits

- Run regular hackathons that pair municipal staff with local students and devs (apply the P&D approach: tiny teams, short sprints). Reward contributions with “participation credits” and fast-track adoption into the marketplace.

4) Analytics for Continuous Improvement

- Instrument every microservice to feed anonymized usage metrics into a shared dashboard (something like an “analysis bureau” idea). Use data to iterate policies and to tie service performance to elected accountability — but keep it privacy-first.

Why this matters: the infrastructure is already there (197 services, many providers). The missing piece is design, packaging, and the organizational muscle to reuse work across towns. This saves budget, reduces vendor lock-in, and improves citizen experience.

まとめ

• Data: 197 MyNa-based services exist, yet municipalities still face heavy admin friction.
• My background (leading P&D) taught me how to mobilize unpaid builders and ship tiny, useful pieces fast.
• My product experience (Cinderella Time) proved that low-friction UX drives real behavior change.
• Proposal: a shared marketplace of audited MyNa microservices + admin SDKs + civic hackathons + analytics.

おかむーから一言

Tech isn’t magic, but it’s a multiplier. If we package what already exists into tiny, usable pieces and teach municipalities to assemble them, we can make public services simple, fast, and humane. Let’s build the marketplace and get people using it — together.
