Hyper-Kamiokande (Hyper-K) is a proposed next-generation general purpose neutrino detection experiment. It comprises an underground water Cherenkov detector that will be more than 8 times as large as the highly successful Super-Kamiokande and use significantly improved photodetectors with the same 40 % photocoverage. The resulting sensitivity improvements will particularly benefit astroparticle physics at low energies.
This talk will give an overview over Hyper-K and present its projected physics reach in the areas of supernova neutrinos, solar neutrinos and indirect dark matter searches, based on the current design report. It will also discuss additional sensitivity improvements if the second detector is built in Korea in a location with a higher overburden.
