One of the important questions for the Belle II experiment is the CP violation in the charm sector. In the Standard Model, charm CP violation is expected to be very small beyond the sensitivity of Belle II. Therefore, its discovery can be a clear signal for new physics. In this talk, we present the efforts by Belle II in the studies of charm CP violation, trying to reduce the systematic uncertainties and to increase effective sample size. The main features of Belle II along with its initial performances will be discussed. Then studies of time-integrated and time-dependent charm CP violations are discussed with expectations for Belle II luminosity target.
