We were selected as a finalist in the Tokyo Governor's Cup Open Data Hackathon, held at the end of August.
The Tokyo Metropolitan Government even featured us on their site.

The Tokyo Governor's Cup Open Data Hackathon is an event where participants build new services and applications using open data published by the Tokyo Metropolitan Government.
Developers, designers, data scientists, and people from all kinds of backgrounds come together, form teams, and turn their ideas into working products.


What we built
This time I teamed up with two friends! Our team name was The Hacking Debt!
The three of us — Taisho, Kitajima Sangyo, and yours truly (coiai-chan) — entered together.
Here's what the service does:
It plots accessible restroom data from TOKYO OPEN DATA on a map, visualizing locations and facility details. The app also gives every Tokyo resident a way to help solve this social issue: when someone uploads accessible restroom information from their phone, that data gets added back into TOKYO OPEN DATA, so residents themselves help expand the city's dataset. And when a registered accessible restroom actually gets used, a thank-you message goes out to the person who contributed that information.
That's the gist of it. It's nice to have some kind of credibility to point to when talking with new clients — it's a lot easier to make an ask when you've got a track record behind you rather than showing up out of nowhere.
