J-PARC muon facility

This is the authors' abstract. We don't add key points for this paper.

The J-PARC muon facility is a pulsed muon beam facility located in the Materials and Life Science Experimental Facility. It has four muon beamlines and seven experimental areas in operation, and a new beamline (H-line) and two new experimental areas (H1 and S2 area) started operation in January 2022. They are used for fundamental physics experiments, such as precise measurements of muoniums, and a search for μ-e conversion. Further extension of the H-line is ongoing to develop a novel low emittance muon beam for a muon $g-2$/EDM experiment and a muon transmission microscope. For more future planning, the conceptual design of a new target station, which allows for over 50 times more intense muons, is underway.
