Microwave spectroscopy of muonium is being prepared at J-PARC. A major improvement of statistical uncertainty is expected with the higher muon intensity of the pulsed beam at J-PARC, while further improvements depend on the size of systematic uncertainties. Reduction of various sources of systematic uncertainties are being studied: those arising from microwave power fluctuations, magnetic field inhomogeneity, muon stopping distribution, and atomic collisional shift of resonance frequencies.
