Neutrino and Kamiokande

Mr. Koshiba was awarded the Nobel Prize in Physics for successfully observing neutrinos, one of the elementary particles that form the basis of matter, and opening up a new field of neutrino astronomy.
In order to observe neutrinos, we constructed a large observation facility Kamiokande under the Kamioka mine in Gifu prefecture, and observed neutrinos for the first time in the world.


Currently, observations are being continued at Super-Kamiokande, the successor to Kamiokande.
Mr. Kajita, a student of Mr. Koshiba, discovered that neutrinos have mass.


As a successor to Super-Kamiokande, Hyper-Kamiokande is under construction with the aim of starting experiments in 2027.
I’m looking forward to discovering new facts at Hyper-Kamiokande.
