Abstract: T2K is a long-baseline neutrino oscillation experiment in which a $\nu_{\mu}$ beam is produced at the J-PARC facility and detected 295 km away by the Super-Kamiokande, water Cherenkov detector. Up to May 2013, T2K has accumulated $6.57\times 10^{20}$ protons on target, approximately 8\% of the experimental goal. T2K has observed 120 $\nu_{\mu}$ candidates, which show a clear disappearance oscillation pattern, and 28 $\nu_e$ candidates, with which $\nu_e$ appearance was established. The measurement of $\nu_e$ appearance is particularly important because it enables us to determine $\delta_{\textrm{CP}}$ when $\theta_{23}$ and $\theta_{13}$ are known. Using values of $\theta_{23}$ determined by T2K disappearance measurements and $\theta_{13}$ measured by reactor $\bar{\nu}_e$ experiments, T2K has obtained the first constraint on $\delta_{\textrm{CP}}$ from a $\nu_e$ appearance measurement.
