AB  - T2K is a long-baseline neutrino oscillation experiment in which a ν<sub>μ</sub> 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 6.57×10<sup>20</sup> protons on target, approximately 8% of the experimental goal. T2K has observed 120 ν<sub>μ</sub> candidates, which show a clear disappearance oscillation pattern, and 28 ν<sub>e</sub> candidates, with which ν<sub>e</sub> appearance was established. The measurement of ν<sub>e</sub> appearance is particularly important because it enables us to determine δ<sub>CP</sub> when θ<sub>23</sub> and θ<sub>13</sub> are known. Using values of θ<sub>23</sub> determined by T2K disappearance measurements and θ<sub>13</sub> measured by reactor ―ν<sub>e</sub> experiments, T2K has obtained the first constraint on δ<sub>CP</sub> from a ν<sub>e</sub> appearance measurement.
