In this talk, I will briefly review history of neutrino physics and current situation of the neutrino oscillation experiments. Then, I will present updated results on the atmospheric neutrinos using Super-Kamiokande 700 day data, which further solidifies the observation reported last summer as "Evidence for oscillation of atmospheric neutrinos". I will also discuss very intriguing Super-Kamiokande results on Solar neutrinos. And finally, I will briefly discuss the upcoming long baseline neutrino oscillation experiments, notably the K2K experiment, that are set to confirm the atmospheric neutrino results.
