Using the Subaru very deep K'-band imaging and HST WFPC2/NICMOS archival data of the Hubble Deep Field North, we investigate the evolution of the stellar mass, color, morphology of galaxies to z ~ 3. We mainly examine the rest-frame U-V color distribution of galaxies as a function of stellar mass. At 0.32, it is seen that more massive galaxies tend to have redder U-V color over the range of 10^9-10^10 M_solar. These results suggests that the star formation history of galaxies depends on their stellar mass very much. The low-mass population is likely to have relatively long star formation timescale. At the stellar mass larger than ~5x10^9 M_solar, there must be some mechanisms which suppress the star formation in galaxies at 0
