The Japan Society of Medical Physics (JSMP) held a joint symposium with the Korean Association of Medical Physicists in North America (KAMPiNA) and the Korean Society of Medical Physics (KSMP) on July 26, 2025, at the venue of the American Association of Physicists in Medicine (AAPM) Annual Meeting in Washington, DC. This symposium originated from a joint symposium held with the AAPM by the organizing committee during the 2021 Korea-Japan joint meeting on Medical Physics (KJMP), which was held online because of the COVID-19 pandemic. Building on this collaboration, the JSMP International Affairs Committee consulted with KSMP and, with the cooperation of the AAPM International Affairs Committee, held the first symposium in a hybrid online and in-person style at the 2022 AAPM Annual Meeting. Since then, it has been held at the annual meeting, with 2025 marking its fourth iteration. This paper presents a record of these events.
Dosimetry protocol for absorbed dose to water using medical linear accelerator was published as JSMP guideline: a code of practice for dosimetry using a radiotherapy ionization chamber calibrated in a clinical linac (JSMP Linac Standard Dosimetry 24) in 2024. Formalism and implementation were simplified, and uncertainty of dose delivery was significantly reduced compared to currently prevailed dosimetry protocol of Standard Dosimetry 12 whose reference quality is 60Co gamma radiation. In this report outline and practice of JSMP Linac Standard Dosimetry 24 including comparison with Standard Dosimetry 12 was discussed.

The 127th Scientific Meeting of the Japan Society of Medical Physics (JSMP127) was held jointly with the 83rd Annual Meeting of the Japanese Society of Radiology (President: Masahiro Jinzaki), the 80th Annual Meeting of the Japanese Society of Radiological Technology (President: Toru Negishi), and the International Technical Exhibition of Medical Imaging (ITEM 2024) from April 11 (Thursday) to April 14 (Sunday), 2024, at the Pacifico Yokohama. The opening ceremony featured a spectacular calligraphy performance in which the theme of JRC2024 "Leading an Era of Transformation" was written to the accompaniment of shamisen and taiko drums, followed by keynote speeches by the presidents of the conferences. In JSMP127, an attempt was made to omit the ethics review at the time of acceptance of abstracts by including the ethics approval number at the time of abstract submission. This trial has greatly reduced the amount of time and effort required for ethics review, which used to be very labor-intensive. This method was very effective and will be adopted for the ICRPT abstracts of JRC2025. All of the programs that were planned in line with the JRC2024 theme, "Leading an Era of Transformation," were truly outstanding, and to sum up the conference in a few words, I can only say "I really enjoyed the conference!!" In conclusion, I would like to express our sincere gratitude to Dr. Satoshi Tanabe, Chair of the Executive Committee, Mr. Hideki Kojima, Chair of the Program Committee, and other members of the Executive Committee and Program Committee for their great cooperation in organizing this academic conference. I would like to deeply express my gratitude to all those who cooperated with us in the management of this conference.
