Software development in Saga and Karatsu

Instead of adapting your business to a package, we build systems that fit your business — for both companies and local governments.

AI puts custom software within reach

From requirements to launch in a short time. We use AI to organize and import data from Excel, paper and legacy systems, and deliver with data entry, transcription, reporting and notifications automated.

Routine entry and reporting shrink, so a small team can keep things running.

Mix and match to suit your project.

* Works listed include services designed, developed and operated by our team members before joining the company.

From small pilots to systems residents use.

Tourism, local information, disaster prevention and welfare. Drawing on deployments and pilots with local governments in and around Saga, we design for both the resident experience and the staff workload.

“We can’t see how visitors move”

We aggregate GPS and QR visit data to inform next year’s plans and reports.

“We built an app, but nobody uses it”

Browser-based, no install. One QR code to join — and the data stays with you as an asset.

“Local information is stuck on paper and PDFs”

A map platform staff can update, shared across tourism, disaster prevention and facility guides.

“Budgets and staff are limited”

Start with a focused, small pilot. Operations are designed around staff procedures.

Our goal isn’t to “make an app” — it’s to leave behind a system residents and visitors use and staff can run.

What we build

Formats: browser-based web apps / PWAs / staff admin panels / integration with existing sites and open data / AI & image recognition

Tourism circulation

Digital stamp rallies, tourist maps, photo contests, signage and tour campaigns.

Examples|go-quest (6 municipalities) and more

Local info & disaster prevention

Fire-water and street-light maps, facility guides, community photo maps.

Examples|Yoshinogari fire-water map and more

Public transport

Timetables, stop search, route guidance and vehicle locations from GTFS data.

Examples|GTFS vehicle location service

Facility operations

Public facility booking, AI parking-occupancy detection, smart-lock access.

Examples|Yoshinogari facility booking, parking occupancy

Welfare & monitoring

Monitoring for seniors living alone: face detection, notifications to family and caregivers, video calls.

Examples|Koyomiru AI (pilots in Arita and Karatsu)

Data analysis & AI

Tourism analysis from GPS movement data, image recognition, congestion visualization.

Examples|AI tourism map (Saga Prefecture)

From pilot to full operation

A focused pilot surfaces operational issues early. We can start with a single-year small-scale pilot.

  1. Scope

    Define the area, facilities, users and goals

  2. Pilot design

    Decide minimum features, period, owners and evaluation

  3. Review

    Check participation, inquiries and staff workload

  4. Roll out

    Apply improvements and decide on expansion
