Abstract
There are two plans of experiments to search for muon to electron ($\mu$-$e$) conversion at J-PARC, which are called DeeMe and COMET. The $\mu$-$e$ conversion is one of the charged lepton flavor violation processes. The processes are forbidden in the Standard Model, but some theories beyond the Standard Model predict relatively large branching ratios at orders of $10^{-12}$ to $10^{-17}$. DeeMe will be conducted with a sensitivity of $1\times10^{-13}$ using a carbon target for 1 year, and COMET will be done with that of $3\times10^{-15}$ in Phase-I. In this article, the current status of these two experiments will be presented.

Report
The proceedings present the state of preparaions for two muon-electron conversion experiments, COMET and DeeMe, which are expecting to take data within the next few years and will have better sensitivity than existing results by orders of magnetude. The proccedings are written by a member of the DeeMe collaboration, and emphasises that experiment. As a comparitively small experiment, up-to-date information directly from a member of the DeeMe collaboration is realtively uncommon in proceedings and similar literature.
