Title: "Upgrade plan of the T2K experiment toward leptonic CP violation search”

Abstract: T2K presented a hint that the symmetry between matter and antimatter may be violated for 
neutrino oscillation with 95% C.L. in summer  2017. Toward better precision of leptonic CP violation 
search, T2K  has proposed a run extension up to 2x10^22 POT with upgrade programs. One of the program 
is an upgrade of neutrino beamline to  accept high intensity of proton beam from J-PARC main ring up 
to 1.3  MW being upgraded in a few years. Another program is to upgrade T2K  near detector to suppress 
systematic error in coming precision era,  aiming to install in 2021. In this seminar I will present 
status and  prospects of the upgrade programs for the T2K experiment.
