BSides (Security BSides) is a community-driven information security conference series held around the world.

It emphasizes openness, accessibility, and the free exchange of knowledge, welcoming researchers, engineers, students, and anyone interested in security. BSides events are known for fostering diverse perspectives, hands-on technical presentations, and lively discussions. With a grassroots, low-commercial approach, BSides encourages new ideas and experimentation.

BSides Tokyo embraces this spirit and provides a space where Japan’s security community can learn, connect, and grow together.

The next event is scheduled for May 2026.
