Location change from Osaka to Nagoya

The city and venue of ICRC2023 have been changed due to unpredictable COVID-19 situation and travel restrictions in 2023. To smoothly prepare and organize the large in-person conference, we decided to change the venue from Osaka International Convention Center to Nagoya University.

Registration and Abstract Submission

The dedicated webpage and website for the registration and abstract submission procedures are scheduled to open in December 2022.

We look forward to seeing you in Nagoya.

Best regards,

Shoichi Ogio for the ICRC2023 Local Organizing Committee
