ILC-Japan Detector WG meeting was held on 18 Mar. We planned a one-day workshop on detectors for Higgs factories. The aim is to review and compare the detector concepts of various Higgs factory projects, and to create a forum for discussing how Japan should proceed with the development of detectors for such facilities. We also structured the workshop content to facilitate discussion on how to promote detector development in a way that enables collaboration beyond the ILC community. (The date is currently being coordinated for mid to late July.)
