This short report presents the most recent results of GRB observations with the Ginga satellite. Since the launch of Ginga in 1987, three GRBs with the cyclotron spectral feature have been observed. Some of the observed GRBs exhibited precursor in the soft X-ray energy band (1--10 keV) which preceded the main flash of gamma-ray photons above several tens keV. These two topics are reported with figures.
