Abstract
Neutrino oscillations, and therefore the small neutrino masses, were discovered by the studies of atmospheric neutrinos in a large underground detector Super-Kamiokande. The experimental studies that led to the discovery will be discussed. In addition, I will discuss the future prospect of researches in Kamioka.

Dr. Takaaki Kajita was born in Higashimatsuyama, Saitama, Japan. He studied at Saitama University and received his doctorate in 1986 at the University of Tokyo. His doctoral advisor was the future Nobel Laureate Masatoshi Koshiba. Since 1988 he is affiliated with the Institute for Cosmic Radiation Research, University of Tokyo, where he became an assistant professor in 1992 and professor in 1999. Later in 2015 he became its director. The Standard Model used by modern physics has three types of a very small and elusive particle called the neutrino. In the Super-Kamiokande detector, an experimental facility in a mine in Japan in 1998, he detected neutrinos created in reactions between cosmic rays and the Earth's atmosphere. Measurements showed deviations, which were explained by the neutrinos switching between the different types. This means that they must have mass. The Standard Model, however, is based on neutrinos lacking mass and the model must be revised. This discovery helped prove the existence of neutrino oscillation and that neutrinos have mass. Dr Kajita received the Label Prize in Physics for this discovery.Awards and honor
