In the T2K long-baseline neutrino oscilliaton experiment, the J-PARC facility is able to produce a high-intensity muon neutrino (antineutrino) beam, which is sent towards the near detector stations (0.28 km) and the far detector Super-Kamiokande (295 km). The change in the measured intensity and the composition of the beam are used to provide information about the oscillation parameters. A simultaneous analysis of the above neutrino and antineutrino mode data sets leads to the first ever sensitivity to the neutrino-sector CPV based on T2K data alone. Also, it gives the most precise T2K measurements of other neutrino oscillation parameters. The proposal of an extension of the currently approved T2K running from 7.8 × 1021 protons on target to 20 × 1021 protons on target and aiming at the initial observation of CPV with 3σ or higher significance assuming maximum CP violation, is also presented.
