  Hyper-Kamiokande (Hyper-K) is a next generation large water Cherenkov
detector to be built in Japan, based on the highly successful Super-Kamiokande
detector. Hyper-K will offer a broad science program including neutrino
oscillation studies, proton decay searches, and neutrino astrophysics with
unprecedented sensitivities. This paper provides some highlights of the physics
potential of Hyper-K.
