Research Projects

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.

The Hyper-Kamiokande detector which will start its operation in the late 2020's, is planned to consist of an order of magnitude larger tank than predecessor experiment Super-Kamiokande's and ultra high sensitivity photosensors. It is the aim of Hyper-Kamiokande to elucidate the Grand Unified Theory and the history of the evolution of the Universe through an investigation of proton decay and CP violation, together with the observation of neutrinos from supernova explosions.

A neutrino experiment designed to investigate how neutrinos change from one flavour to another as they travel (neutrino oscillations) with an intense beam of muon neutrinos generated at the J-PARC and the Super-Kamiokande neutrino detector.

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

Very high energy cosmic gamma ray observation.

Search for point sources of VHE cosmic gamma at Tibet heights.

High Energy Astrophysics Group studies various high-energy astrophysical objects, which are sources of cosmic rays, via mainly theoretical method.

Observation of UHE cosmic gamma rays and cosmic rays at Mt. Chacaltaya, Bolivia.

We aim to promote gravitational wave astronomy by participating the world gravitational wave observation network with the large-scale cryogenic gravitational wave telescope, KAGRA.

Armed with the state-of-the art telescopes such as Subaru and Hubble, we aim to push the today's observational frontier towards the very high redshift universe that no one has ever seen by observations. Our goal is understanding physical processes of galaxy formation at the early stage and the relevant event of cosmic reionization.

Theoretical studies for verifying Grand Unified Theory and early Universe.
