Hyper-Kamiokande, Neutrino detector facility in Hida, Japan

Hyper-Kamiokande is a neutrino detector facility located 1000 meters underground at Mount Ikeno, filled with 260 kilotons of ultra-pure water held in a cylindrical stainless steel tank. The structure uses sensitive light-detection technology to observe the faint flashes created when neutrinos pass through the water.

The project builds on decades of research at the Kamioka Observatory, which produced fundamental discoveries about neutrino oscillations starting in 1983. This new facility continues that work with greater capacity to unlock deeper insights into particle physics.

Researchers from universities around the world work together at this facility, forming an international team focused on understanding particle physics. Their collaboration brings different perspectives to solving the mysteries of the subatomic world.

The deep underground location shields the equipment from cosmic radiation interference and allows for more precise measurements of particle interactions. Access to the facility is limited since it operates as a specialized research center with strict safety protocols.

This facility will process neutrino data with ten times more capacity than Super-Kamiokande, its predecessor. This massive increase in detection power opens entirely new research directions that were previously beyond technical reach.
