* Abstract : T2K is an accelerator neutrino experiment by using the neutrino beam produced by the proton accelerator J-PARC and by using a gigantic neutrino detector, Super-Kamiokande. T2K started physics data taking in 2010, and first found the indication of a new type of neutrino oscillation, an appearance of electron neutrinos in the muon neutrino beam in 2011. In 2016, by studying oscillations of both neutrinos and anti-neutrinos, T2K find a hint of neutrino CP violation.
In the seminar, we report the most resent results from the T2K experiment. Recently, the T2K collaboration proposes the upgrade of T2K, so called T2K-II with a higher beam power and with an improved detector performance. In addition, as an successor of the Super-Kamiokandse detector, we are proposing the further bigger neutrino detector, Hyper-Kamiokande. In the seminar, we will introduce the physics potential of T2K-II and Hyper-Kamiokande to probe the mysteries of neutrinos.
