The JSNS^2 experiment will search for the existence of neutrino oscillations with Delta m^2 near 1 eV^2 at the J-PARC Materials and Life Science Experimental Facility (MLF). A 1 MW proton beam (3 GeV) incident on a mercury target produces an intense neutrino source from muon decay at rest. The oscillation to be searched for is from anti-muon neutrinos to anti-electron neutrinos, detected via the inverse beta decay (IBD) reaction, which is then distinctively tagged by gammas from neutron capture of Gadolinium. The first of two detectors with 17 tons fiducial volume is currently under construction at a distance of 24 m from the mercury target. JSNS^2 is expected to provide the ultimate test of the LSND anomaly by replicating nearly identical conditions, however with a significantly improved experimental setup. The status of the experiment, which is expected to start data during the next few month, is discussed and its physics potential reviewed.
