  We study the sensitivity of the existing MEG data to lepton flavor violating
axion-like particles produced through $\mu^+ \to e^+ a \gamma$ and estimate the
discovery potential for the upcoming MEG II experiment in this channel. The MEG
II signal efficiency can be improved significantly if a new trigger can be
implemented in a dedicated run with a reduced beam intensity. This search would
establish the world leading measurement in this channel with only 1 month of
data taking.
