Abstract
The Belle II experiment is a major upgrade of the Belle detector, operating at the SuperKEKB energy-asymmetric $e^+e^-$ collider with a design luminosity of 8×$10^{35}$~cm$^{-2}$s$^{-1}$. To date, the detector has recorded over 200 fb$^{-1}$ of data and aims to collect 50 ab$^{-1}$, a factor of x50 more than its predecessor. Belle II has a broad $\tau$ physics program, from high-precision measurements of SM parameters to searches of new physics via experimental probe of BSM processes. In this work, we review the status of the Belle II experiment, and the prospects for the measurement of the $\tau$ lepton mass and lifetime, fundamental inputs in tests of LFU violation.

Report
Prospects of precision measurements of the properties of the tau lepton at the Belle II experiment are presented. The status of measurements of the mass and lifetime of the tau lepton are discussed. Precision measurements of these parameters have important consequences in searches like
lepton flavor universality violation induced by beyond Standard Model interactions.
Overall scientific quality of the contribution is very high.
Referee recommends publication following resubmission with minor corrections.
