Hyper-Kamiokande is a next-generation, long-baseline neutrino experiment
under construction in Japan. It will measure neutrino oscillations using the J-PARC neutrino beam which
is now serving the T2K experiment. The Hyper-Kamiokande far detector
has a fiducial volume 8 times the size of the currently-running
Super-Kamiokande detector, and will be instrumented with new photosensors. Combined with an upgraded J-PARC neutrino beam, Hyper-Kamiokande will be able to measure neutrino oscillations with unprecedented statistical precision, enabling the potential discovery of CP-violation and precise measurements of the atmospheric oscillation parameters.
The Hyper-K sensitivity for a 10-year exposure shows 5-$\sigma$ significance for the discovery of CP violation for $>55$% of true $\delta_{CP}$ values and determination of the $\sin^2\theta_{23}$ octant for values outside (0.44, 0.58). This proceeding describes the Hyper-K analysis strategy including upgraded near detectors and the newly proposed Intermediate Water Cherenkov Detector (IWCD). The ability of these upgrades to minimize systematic uncertainties will be described, with emphasis on their effect on the neutrino oscillation sensitivity of Hyper-K.
