Abstract
The Belle II experiment is an upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric $e^+e^-$ collider. The accelerator has already successfully completed the first phase of commissioning and first electron positron-collisions in Belle II were observed in April 2018. The design luminosity of SuperKEKB is 8x10$^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than the Belle experiment. Belle II has a broad program of $\tau$ physics, in particular, precision measurements of Standard Model parameters and searches of lepton flavor and lepton number violations (LFV and LNV), benefiting from the large cross-section of the pairwise $\tau$ lepton production in $e^+e^-$ collisions. In this talk, we will review the $\tau$ lepton physics program of Belle II.

Report
This paper reports on the status of the Belle II experiment and the feasibility of tau physics at the Belle II. The study using the data taken during the first collisions shows a good status of the new detector. The large statistics at the BelleII would allow great improvement of the precision for the study of the lepton flavor violation, CP violation, Michel parameters, and new physics.
The studies has been described elaborately. The quality of the paper is high, minor corrections to the content would further improve it.
This is an important contribution to the field of tau physics and I recommend it for publication.
