Research Projects

Neutrino and Astrophysics Research

Super-Kamiokande

Super-Kamiokande aims to reveal the Universe’s history and to explore the nature of elementary particles through the observation of neutrinos and a discovery of proton decay.

High Energy Cosmic Ray Research

Telescope Array(TA)

Aiming at highest energy cosmic ray physics by detecting weak light from atmosphere.

Astrophysics and Gravity Research

HISTORY

Timeline

The Institute for Cosmic Ray Research (ICRR) conducts observations and studies cosmic rays from various aspects. Its predecessor was a lodge for research, called Asahi Hut, built on Mt.Norikura based on an Asahi Academic Grant. In 1953, it was transformed into the Cosmic Ray Observatory of The University of Tokyo.
