The neutrino oscillation is caused by transition amplitude between different flavour neutrinos. The transition between different flavour quarks, which generate the CKM mixing matrix, is understood to be caused by the Yukawa coupling to the Higgs field. However, for neutrino case, the origin of the transition is not understood yet. An important purpose of the neutrino oscillation experiments is to measure the transition amplitudes and explore its origin. Another important purpose is to study effects of the neutrino oscillations to our world, like the violation of CP symmetry, to understand our universe. Recently the last neutrino mixing angle Theta13 has been measured by the Double Chooz, Daya Bay and RENO experiments, T2K and MINOS experiments have observed nu_mu to nu_e appearance oscillation caused by the finite Theta13 and the neutrino oscillation measurements have entered a new era. Now we know all the standard neutrino mixing angles and mass squared differences, and can study transition amplitudes more concretely than before. Relatively large Theta13 gives a possibility to measure the CP violation and (1-3) mass hierarchy in future experiments. In this presentation, the speaker will summarise the current situation of the neutrino oscillation measurements and look out future possibilities.
