The upcoming Hyper-Kamiokande experiment will be the third generation of water Cherenkov detectors situated in Kamioka, Japan, following in the footsteps of the highly successful Kamiokande and Super-Kamiokande experiments. Hyper-K will aim to continue and improve upon their various physics goals, such as the study of neutrino oscillations, astrophysical neutrinos and proton decay. To make these measurements a reduction in systematic error levels is required, towards which a range of calibration sources, a new detector, IWCD, and new techniques are currently being developed.
