  Hyper-Kamiokande 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 contribution to the EPS-HEP 2017 proceedings
gives an overview over Hyper-Kamiokande and presents its projected physics
reach in the areas of supernova neutrinos, solar neutrinos and indirect dark
matter searches, based on the current design report. It also discusses
additional sensitivity improvements if the second detector is built in Korea in
a location with a higher overburden.
