Abstract: The T2K experiment is one of the accelerator based long baseline experiments. The neutrinos produced in the J-PARC neutrino beamline are detected in Super-Kamiokande, 295 km away from the neutrino production target. We have started physics run in early 2010 and accumulated data corresponding to 6.57 x 10^20 protons on target until May 2013, which is about 8% of the planned running. This time, we have analized the entire data set and extracted the neutrino oscillation parameters, Delta m_32, theta_23. Also, we did the combined analysis of the data from T2K and the reactor anti-neutrino disappearance experiments to study the CP violating phase delta_CP. In this talk, these latest results are presented and the future of the T2K experiment is also discussed.
