Query: The Hyper-Kamiokande Experiment: Overview & Status   The Hyper-Kamiokande (HK) experiment centres around a proposed
next-generation underground water Cherenkov detector that will be nearly 20
times larger than the highly successful Super-Kamiokande experiment and use
significantly improved photodetectors with the same 40% photocoverage. HK will
increase existing sensitivity to proton decay by an order of magnitude, and it
will study neutrinos from various sources, including atmospheric neutrinos,
solar neutrinos, and supernova neutrinos. In addition to operating as a
standalone experiment, HK will serve as the far detector of a long-baseline
neutrino experiment using the upgraded J-PARC neutrino beam, enhancing searches
for lepton-sector CP violation.
  This contribution to the NuPhys2016 proceedings presents recent developments
and the current status of the experiment. It discusses ongoing photosensor R&D
efforts and the expected physics reach in the area of supernova neutrinos as
showcased in the recently published design report. Other physics topics,
including neutrino oscillations and nucleon decay, are discussed in a separate
contribution to these proceedings.
