Neutrino Oscillation Experiments:. Super-Kamiokande K2K and the Jparc Neutrino Project

Neutrino oscillations have been studied using various neutrino sources including solar, atmospheric, reactor and accelerator neutrinos. Our understanding on neutrino masses and mixing angles has been improved significantly by recent experiments. This report mainly discusses the present status and the future prospect of our understanding of neutrino masses and mixing angles that are related to larger Δm².
