Summary
The 78th Social Hack Day, a recurring one-day hackathon run by Code for Japan. Participants bring ideas they want to realize or civic tech projects already in progress, recruit collaborators, and build services together hands-on. You can join in person at a venue in Tokyo or online via Zoom.
The day starts with a guide for first-timers, an opening, and project introductions, followed by two development blocks with a midpoint check-in and a final progress and results report. Participants include not only engineers and designers but also NPO staff, government employees, and professionals from fields such as healthcare and education. A small participation fee applies, and attendees bring their own PC and online-meeting setup.
