The results from K2K-I are the $ν_μ$ disappearance, $ν_e$ appearance, and studies of neutrino interaction with water nuclei. For K2K-II, steady increase of POT (number of Protons On Target) and number SK events are shown. Also, a new front detector SciBar was installed from K2K-II.Proceedings for the XXXIXth Rencontres de Moriond session devoted to Electroweak Interactions and Unified TheoriesHigh Energy Physics - Experimenttext
