T2K experiment & J-PARC E69(WAGASCI) experiment
T2K experiment to observe artificial neutrino beam generated at J-PARC with Super-Kamiokande is in fierce competition with NOνA experiment aiming at discovery of particle-antiparticle (CP) symmetry breaking in neutrinos. The mission of our laboratory is to realize the world's first discovery of CP symmetry breaking in neutrinos by T2K experiment by constructing new neutrino detectors(WAGASCIs/Side-MRDs in J-PARC E69 and SuperFGD in T2K ND280 upgrade) and by measureing neutrino interactions in detail with them.

Hyper-Kamiokande
Hyper-Kamiokande with about 10 times the volume of Super-Kamiokande will enable us to improve the sensitivities to search proton decay, particle-antiparticle (CP) symmetry breaking in neutrinos, neutrinos from Supernova Burst and so on drastically. The detector will greatly advance human understanding of the universe. The new neutrino detectors(WAGASCIs/Side-MRDs in J-PARC E69 and SuperFGD in T2K ND280 upgrade), which we are developing in our laboratory, can contribute to improve the sensitivity of CP symmetry breaking search in neutrinos by Hyper-Kamiokande. The mission of our laboratory is to contribute to the construction of Hyper-Kamiokande as core members and to start the experiment earlier than the rival DUNE experiment.

Super-Kamiokande
SK-Gd project is aiming to make the world's first observation of Supernova Relic neutrinos by dissolving gadolinium in Super-Kamiokande. So far, the preparation work inside Super-Kamiokande has been completed and it is ready to dissolve gadolinium. The mission of our laboratory is to explore new physics using the new gadolinium-doped Super-Kamiokande.

J-PARC E71(NINJA) experiment
J-PARC E71 (NINJA) experiment is measuring the T2K neutrino beam with nuclear emulsion detectors which have ultimate position resulution to measure neutrino interactions in detail. The mission of our laboratory is to realize hybrid observation of J-PARC E69 (WAGASCI) and J-PARC E71(NINJA) experiments, and support the world's first discovery of CP symmetry breaking in neutrinos by T2K experiment by reducing systematic errors of neutrino interactions.
