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.
