Summary
A one-day AI hackathon in Chiyoda, Tokyo, limited to 70 participants. The theme is open innovation: build anything that uses AI and actually works, whether an agent, an app or any other software. Teams form in advance or at a structured matchmaking session at 10:30, and solo entries are welcome. Participation works in either English or Japanese.
Hacking runs from late morning to a 16:00 submission deadline, with judging at each table, live demos from the top five teams and an awards ceremony. Sponsors Neo4j (graph database for agent memory and retrieval) and ai& (a Japan-hosted GPU inference API with OpenAI- and Claude-compatible endpoints) provide credits, and judges include AI leads from Microsoft Asia, ai& and AlgoMori. Food is provided throughout the day.
