The Particle Accelerator Society of Japan as a General Incorporated Association

Abstract

The Particle Accelerator Society of Japan (PASJ) was established in 2004 and has grown significantly since then, leading accelerator research in Japan. While the number of members at the time of its establishment was 473, the current number is approximately 900. The doubling of the number of members over the past 20 years is a testament to the growth of the society. The PASJ has been operated as a voluntary organization, but on April 1, 2024, the 20th anniversary of its establishment, it became a general incorporated association. We would like to discuss the background behind the decision to incorporate, as well as the future of the PASJ as it moves forward as a general incorporated association.
