| January 2023 | Reported new limits on sub-GeV dark matter based on data collected from 1996-2018, excluding dark matter-nucleon elastic scattering cross sections between 10^-33 cm^2 and 10^-27 cm^2 for masses ranging from 1 MeV/c^2 to 300 MeV/c^2. |
| 2020 | Detector upgraded for SuperKGd project by adding gadolinium salt to enable antineutrino detection from supernova explosions. |
| January 29 2019 | Detector resumed data acquisition after refurbishment. |
| 2018 | The 200-ton EGADS prototype with added gadolinium sulfate finished its operational testing in the Kamioka mine, successfully demonstrating the feasibility of maintaining gadolinium concentration while purifying water. |
| 2018 | Detector underwent full refurbishment during autumn. |
| September 2018 | Super-Kamiokande detector was drained for maintenance, allowing Australian Broadcasting Corporation reporters to film 4K resolution video inside the detection tank. |
| June 2018 | Super-Kamiokande-IV data collection ended. |
| 2015 | Takaaki Kajita awarded the Nobel Prize in Physics for work confirming neutrino oscillation. |
