Flavor physics has played an essential role in testing the Standard Model(SM) and in searching for new physics(NP) with measurements of CP violation and rare decays. Recently, some discrepancies with the SM are reported in several observables in Kaon and B meson decays, and they may become a hint of NP. One of the exciting topics is the anomaly in the direct CP violation of Kaon, epsilon'/epsilon. Current progress of lattice calculations enables us to predict the epsilon'/epsilon accurately, and the SM prediction for it appears to be significantly below the experimental data. This may suggest a NP model providing enhancement of epsilon'/epsilon. In this talk, I will discuss the new physics implications from epsilon'/epsilon and the effects on other observables.
