Welcome to Carbon Connect 2026, a joint seminar proudly hosted by Yonsei Cancer Center and the East Japan Heavy Ion Center (EJHIC) at Yamagata University Faculty of Medicine.

This collaborative event brings together leading experts from both institutions to discuss the current status, novel indications, and future therapeutic approaches of Carbon-Ion Radiotherapy (CIRT). We sincerely hope this symposium serves as a dynamic platform for meaningful scientific exchange and robust international collaboration to advance the frontier of heavy ion therapy.
