Hyper-Kamiokande (HK or Hyper-K) project is the world- leading international scientific research project hosted by Japan aiming to elucidate the origin of matter and the Grand Unified Theory of elementaly particles. The project consists of the Hyper-K detector, which has an 8.4 times larger fiducial mass than its predecessor, Super-Kamiokande, equipped with newly developed high-sensitivity photosensors and a high-intensity neutrino beam produced by an upgraded J-PARC accelerator facility.

The 6th general meeting of the Hyper-Kamiokande proto-Collaboration was held at Universidad Autónoma de Madrid from 13-16 March 2018

Hyper-Kamiokande is a scientific project supported by relevant Japanese institutes and lead by ICRR U. Tokyo and KEK, and includes the involvement of scientific organisations globally (see http://www.hyper-k.org)
