Hyper-Kamiokande is a next generation large-scale water Cherenkov detector. Its fiducial volume will be about an order of magnitude larger than Super-Kamiokande and the detector performance is significantly improved with newly developed photo-sensors. Combination of the Hyper-Kamiokande detector with the upgraded J-PARC neutrino beam will provide unprecedented high statistics of the neutrino and antineutrino signals to measure the CP violation and reveal a full picture of neutrino mixing with high precision. A set of upgraded and new near detectors will be used to control the systematic uncertainties. In addition to detecting the neutrino beam from J-PARC, the Hyper-Kamiokande detector will be used to search for proton decays, to study atmosphetic and solar neutrinos, and to detect supernova and other astrophysical neutrinos. The construction of Hyper-Kamiokande is going to start in early 2020, with expectation of starting operation in 2027. The design and expected performance of the detectors and the status of project will be presented.
