| Outline of Final Research Achievements |
Neutrino mass hierarchy and CP phase can be determined by placing a far detector in Korea (T2KK) or in Oki island (T2KO) along the T2K baseline.
Neutrino mass hierarchy determination is challenging for medium baseline reactor neutrino experiments planned in China and Korea, but it can be determined swiftly at PINGU, a proposed upgrade of the ICECUBE detector in Antarctica.
Leptonic CP phase can be measured very precisely if we construct a powerful cycrotron, producing neutrinos from stopped muon, by measuring its oscillation at Super-Kamiokande and at Hyper-Kamiokande.
