The T2K long-baseline neutrino oscillation experiment has been running in anti-neutrino mode since 2014 and recently released anti-neutrino oscillation results. These results have been updated with further data and now include the full three-flavor anti-neutrino oscillation analysis. We will present these new results and compare them with the neutrino oscillation results, giving the most sensitive comparison to date. The three-flavor neutrino and anti-neutrino results are used to obtain

... ading measurements of δ CP , θ 23 and ∆m 2 32 . The T2K long-baseline neutrino experiment is in the process of proposing a follow-up experiment, T2K-II, with higher beam intensity, upgraded detectors and improved sensitivity to neutrino properties. The anticipated sensitivity and reach of T2K-II will be discussed in this talk, as well as possible detector upgrades. In particular, the sensitivity should allow for a 3σ discovery of CP violation in the case of maximum CP violation, after 10 years of data-taking.
