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 Osaka International Convention Center (Grand Cube Osaka) in Osaka, 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.

Osaka was the capital of Japan in ancient times and later developed into the commercial center of Japan. Today, it is the center of economic activity in western Japan. The Osaka metropolitan area, formed by Osaka and the surrounding areas of Kyoto, Nara, and Kobe, is a wonderful place to visit. The modern and developed city, the old capital with its history and traditions, and the rich nature of the sea and mountains surrounding it will fill you with excitement and joy as you experience nature, culture, and nightlife. And best of all, Osaka is a very safe area.

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. We are looking forward to seeing you all in Osaka in 2023!

Yours Sincerely,

Prof. Shoichi OGIO (Osaka City University)
