Answer
Kamiokande and Super-Kamiokande were neutrino detectors developed by Masatoshi Koshiba. Kamiokande was the first water Cherenkov detector, located deep underground to reduce cosmic ray interference, and was capable of detecting neutrino interactions with water molecules. Super-Kamiokande was a larger version of Kamiokande with increased sensitivity, allowing for more precise neutrino measurements, especially for solar and atmospheric neutrinos.
