    The most recent progress and future prospects in kaon physics are reviewed. Main results are the first observation of the rare decays KS->pi0ee and KS->pi0mumu by NA48, new K+->pinunu event observed by E949 and new precision measurements of K0->pienu decays by KTeV, KLOE and NA48 made in an effort to resolve the slight deviation from the unitarity in the CKM matrix, involving the |Vus| coupling.Comment: Invited talk at the XXIV Physics in Collisions Conference (PIC04), Boston, USA, June 2004, 19 pages, LaTeX, 3 eps figures.
