Abstract: The Muon g-2/EDM Experiment at J-PARC will employ a novel way to measure the muon magnetic anomaly, $a_\mu = (g-2)_\mu/2$, by using a low-emittance beam of positive muons stored in a compact muon storage magnet. The experimental method includes new technologies such as a three-dimensional spiral injection, an MRI-type storage magnet with superb field uniformity, and a positron tracking detector. The expected systematic uncertainty will be at the same level as that of the FNAL Muon $g\!-\!2$ experiment, providing an important cross-check of the “storage-ring method” employed at BNL and FNAL. I will present the current status of the experiment, ongoing tests and design optimizations, and the plans for improvements of the experimental precision.
