Summary
JJUG CCC 2026 Spring is the largest Java community conference in Japan, held biannually each spring and autumn. Quality sessions cover Java-related technologies and case studies, bringing together Java engineers from diverse fields. This edition is in-person only at Bellesalle Shinjuku Grand Conference Center in Nishi-Shinjuku — no online streaming or archive will be provided, so sessions can only be attended onsite.

All participants must agree to the JJUG code of conduct.
