In this talk I will talk about the recent update on the COMET experiment at J-PARC, which is to search for a charged lepton flavor violating (CLFV) process of muon to electron conversion in a muonic atom. The physics motivation of CLFV will be presented with the recent update from the LHC. Recently the COMET experiment has made significant progress by taking a staged approach to its early realization. The COMET Phase-I, which is aiming at an intermediate sensitivity of more than a factor of 100 improvement over the current limits, would be the first phase. The construction will start in 2013, and the physics run is expected in 2016/2017. The staged approach would provide, in addition to the physics outcomes, additional measurements of background sources to COMET Phase-II that is planned to start in 2020/2021. Also as an R&D for highly intense muon source for COMET, the MuSIC (muon science intense muon channel) facility at Osaka University, which produce the same muon beam intensity as PSI with 1000 times smaller proton beam power, will be mentioned.
