Status of T2K, the Tokai-to-Kamioka long baseline neutrino oscillation experiment

 The discovery of neutrino oscillation and neutrino mass by the Super-Kamiokande and SNO experiments opened a new era in neutrino physics. The T2K, Tokai-to-Kamioka long baseline neutrino oscillation experiment in Japan, aims at measuring the remaining neutrino mixing angle q13, and observe CP violation in the neutrino sector if q13 is large enough.
    The commissioning of the T2K detectors and beamline started in December 2009 and first neutrino events have been observed in the near detector. I will describe the status of the T2K experiment future plan.
