Abstract
The MEG experiment, which is to search for lepton flavor violating muon decay, had been successfully finished in 2013. The final sensitivity of the experiment was 5.3 × 10−13, and since the experiment did not find any signal, the upper limit of the branching ratio of the μ+ → e+γ was set to be 4.2 × 10−13 at 90% CL. The MEG II experiment will improve the sensitivity by an order of magnitude with three years data taking, and the target sensitivity is 6×10−14. In 2018 after the detector integration, the muon beam data taking will be planned with limited number of readout channels. In 2019, the engineering run and the physics run will be started.

Report
The proceedings describe the MEG experiment and development of its successor, MEG-II. The results from MEG are the most precise measurement of charged-lepton flavour violation to date, and MEG-II will start running to significantly improve on this in the near future. This update is clearly written and of interest to the community.
