We held the international workshop “J-PARC Hadron 2023” at AYA’s Quantum Beam Research Center (Tokai, Ibaraki) on September 12-15. The main theme of the workshop is hadron physics which was/is/will be investigated at J-PARC: Strangeness nuclear physics, Hadrons in medium, Heavy quark physics (including exotic hadrons), Relativistic heavy ion collision, and other topics related to J-PARC. During the workshop, participants engaged in enthusiastic discussions about J-PARC hadron physics, not only in the sessions but also during breaks and the banquet. Additionally, we organized a J-PARC tour on the second day afternoon. Attendees to the tour could learn about J-PARC experiments in detail. Therefore, through the workshop, we can understand the current situation of J-PARC hadron physics deeply, and we expect that these discussions will spark numerous new ideas and foster collaborations related to J-PARC hadron physics.

It is worth noting that nearly half of the speakers and the advisory committee members are from Asian countries (China, Korea, Taiwan, Philippines, Myanmar, and Australia). During the workshop, participants frequently engaged in discussions and enjoyed productive communication. Therefore, we could rebuild the network in the field of hadron physics in the Asian region, which has been affected by COVID-19. As we expected, this workshop significantly strengthened our connections and relationships.
