How is the Neutrino, a subatomic particle, observed if it cannot be seen?
This exhibit shows you how it is done with a model of the observation instrument, the Super-Kamiokande.

The Super-Kamiokande is a neutrino detector located 1,000 meters underground in the Kamioka-mine, Gifu Prefecture. This exhibition is a model of the Super-Kamiokande reduced to a tenth of the original size. You can experience actually entering inside the model and looking at the multiple sensors used to detect neutrino lining the floor and the walls.
In addition, you can observe coming and going traces of radiation rays with your own eyes at a device called "Cloud Chamber" where the path followed by radiation rays appears in the form of lines of smoke.
Japan is leading the world in neutrino observation with two Nobel Prize winners (Mr. Masatoshi Koshiba in 2002 and Mr. Takaaki Kajita in 2015).
