We held a symposium entitled “Particle Physics and Early Universe developed with next generation colliders” at the 79th Annual Meeting of the Physical Society of Japan at Hokkaido University on 18 Sep. 2024. We shared the current situation and discussed the future of the Higgs Factories with approximately 150 participants.
