Abstract
The Belle II experiment at the SuperKEKB energy asymmetric e+e−collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is 6×10^35 cm^{−2} s^{−1} and the Belle II experiment aims to record 50ab^{−1]of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure the Cabibbo-Kobayashi-Maskawa (CKM) matrix, the matrix elements and their phases, with unprecedented precision and explore flavor physics with B, charmed mesons, and tau leptons. Belle II has also a unique capability to search for low-mass dark matter and low-mass mediators. In this paper, we will review the status of the Belle II detector, SuperKEKB accelerator and the prospects for physics at Belle II.

Report
This paper, Lalwani, et al. "The Belle II Experiment: Status and Prospects", describes the Belle II experiment, the SuperKEKB accelerator, and the prospective physics that can be probed with this experiment. The description of the Belle II experiment is thorough for a conference proceeding and the description of the status of the ongoing analysis is comprehensive and provides excellent motivation for the experiment. Belle II will continue to take data and has been able to collect data even in the face of the challenges raised by the COVID 19 pandemic.
The manuscript meets the requirements to be published in this journal, and I believe it should be published with only a minor comment.
It would be useful to provide a brief estimate as to when the Belle II experiment will complete data taking. I understand the ever-evolving pandemic situation can present challenges, but those who are unfamiliar with the experiment may benefit from a rough estimate as to when the full data set might be collected. If there is a strong reason to withhold the timeline I would appreciate knowing the reason.
