On October 1st, 2017 the University of Tokyo launched its “Next-generation Neutrino Science Organization (NNSO),” in cooperation with the Institute for Cosmic Ray Research, the Kavli Institute for the Physics and Mathematics of the Universe, and the University of Tokyo’s School of Science. The NNSO is a means of pioneering the future of neutrino physics through the development of neutrino research techniques and detector technologies. In particular, it aims to advance what will become its flagship facility, the Hyper-Kamiokande project. Since 2019, the Earthquake Research Institute has participated in this organization.
In October 2023, the Next-Generation Neutrino Science Organization was reorganized into the “Next-generation Neutrino Science and Multi-messenger Astronomy Organization” to expand our research activities into the field of multi-messenger astronomy. The new NNSO is going to promote the multi-messenger astronomy with our colleagues specializing in theory or data science to coordinate collaborative research with disparate “messengers”, multi-wavelength and multi-particle signals including electro-magnetic waves (Radio, Optical/Infrared, X Ray, Gamma Ray), cosmic rays, neutrino and gravitational waves.
