On 30 Sep, 2016, the KEK-IPNS Director and J-PARC Center Director granted stage-1 status to the T2K collaboration’s proposal for an extended beam data run to search for CP violation by neutrinos. The proposal requests delivery of 20×10²¹ protons-on-target (POT) by 2026, which would allow the possibility of 3 sigma sensitivity for CP violation. In order to achieve this, accelerator upgrades are being planned, as well as upgrades to the neutrino beam line and near detectors. The original T2K run plan is for delivery of 7.8×10²¹ POT.
