Fundamental properties of neutrinos are studied in nuclei as microlaboratory. Hear nuclear responses for neutrinos are crucial. Nuclear isospin and spin-isospin responses, which are relevant to vector and axial-vector weak responses, are studies by charge exchange hadronic reactions. $^{100}$Mo has large isospin and spin responses for neutrinos associated with double beta decays and for solar and supernova neutrinos. Thus MOON(Mo Observatory Of Neutrinos) with multi ton Mo isotopes is of potential interest for neutrino-mass studies with a sensitivity of 0.03 eV by double beta decays, and for realtime studies of solar and supernova neutrinos.
