About

We collect AI hackathons, build events and hands-on AI workshops across Japan — Tokyo, Osaka / Kansai and beyond — and online, with a focus on clear language information for foreign residents, travelers, business visitors and international builders.

What we list

• AI hackathons, build events and build nights
• Vibe coding events
• Hands-on workshops where you actually build with AI

Talk-only conferences and seminars are generally not listed.

Language information

Many Japanese event pages don't say which language is used on the day. We label each event:

• Official information — stated on the official event page
• Organizer confirmed — we asked the organizer by email or phone
• Not confirmed — we couldn't confirm it yet

Meet Hackoo

Hackoo is the husky guide for AI Hackathons in Japan.

He’s here to make AI hackathons feel a little more approachable and easier to explore.

You may spot his face — or sometimes just his ears — throughout the site.

The idea is simple: even if you’ve never joined a hackathon before, Hackoo is here to make the first step feel a little less intimidating.

Please note

Event details may change. Always check the official page before attending.
