* Abstract : We examine physics discovery potential of placing a far detector in Korea along the baseline of the T2HK (Tokai-to-HyperKamiokande) neutrino oscillation experiments, within the three neutrino standard model. Preliminary results for the determination of the neutrino mass ordering, the CP violating phase of the lepton flavor mixing matrix, and resolution of the octant degeneracy in the 2-3 mixing angle are reported for the following configuration of the T2HKK experiment: 2.5 degree off-axis beam at T2K (22kton) and T2HK (100kton), both at L=295km, and a 100kton HK type detector in Korean site H (Mt.Bisul) at L=1088km with 1.3 degree off-axis beam, 2.5 \times 10^{21} POT each for \numu and \numubar beam.
