It is our great pleasure and honor to extend a warm welcome to all of you to the 38th International Cosmic Ray Conference (ICRC2023), which will be held at Nagoya University in Nagoya, Japan.

The ICRC conference series has been held biennially since 1947 by Commission C4 (Astroparticle Physics) of the International Union of Pure and Applied Physics (IUPAP*). The main topics covered by this conference are Cosmic Ray Physics, Gamma-Ray Astronomy, Neutrino Astronomy & Neutrino Physics, Dark Matter Physics, Solar and Heliospheric Physics, Multi-messenger Astronomy, and an additional new topic in the 2023 conference is Gravitational Wave Astronomy. ICRC2023 will provide an excellent forum for you to refresh your knowledge base and explore innovations. We hope that at the end of the conference, participants will feel that they have collected the latest information available in the field of Astroparticle Physics.

The Local Organizing Committee (LOC), the International Scientific Program Committee (ISPC), and the International Advisory Committee (IAC) are jointly organized for ICRC2023. The members of the LOC are very proud to host the ICRC2023 and look forward to welcoming you to our city and country.

Although we are currently under the severe situation of the COVID-19 pandemic, the LOC of ICRC2023 is preparing to hold the international conference in person. However, due to unpredictable situation in summer 2023, we decided to change the host city from Osaka to Nagoya (please read this post). We are looking forward to seeing you all in Osaka Nagoya in 2023!

Yours Sincerely,

Prof. Shoichi OGIO
