We theoretically investigated binary neutron star mergers by Numerical Relativity. We found that such an event could be detected by the gravitational wave observatory KAGRA and Advanced LIGO if it happened within the distance of about fifteen millions light years. We found that neutrinos from such a event could be simultaneously detected by the Hyper-Kamiokande as well. We quantitatively showed that the gravitational waves can assess the so-called merger hypothesis of gamma-ray bursts. If neutron stars have a magnetic field as large as that of magnetars, the amplified magnetic field by the magnetic winding can produce a poynting flux whose amplitude is as large as that of short-gamma ray burst.
