Summary
Social Hack Day is Code for Japan's recurring one-day hackathon where participants bring ideas or ongoing projects, recruit teammates, and build services together hands-on. The 79th edition is the last of the year, held in person at a Tokyo venue with online participation via Zoom, followed by a year-end party.
The day runs through an orientation for first-timers, project introductions, two build sessions, a mid-day check-in, and final progress reports. It is aimed at people working on social-impact projects who need collaborators, NPO staff seeking advice on technology, and engineers and designers who want to apply their skills to civic tech. A small participation fee applies and light catering is provided.
