The Time Reversal Experiment with Kaons (TREK) at J-PARC aims to find CP violation beyond the Standard Model in the semi-leptonic K{sub {mu}}{sub 3}{sup +} decay mode by measuring the T-violating transverse polarization P{sub T} of outgoing muons. TREK makes use of the intense kaon beam at J-PARC stopped in a target and employs an optimized setup with excellent control of systematic uncertainties. The sensitivity at J-PARC is improved by a factor of 20 compared to the current uncertainty for P{sub T}, well in the predicted range of various New Physics models. An overview of the planned experiment and current status will be presented.
