Using the Subaru telescope, we investigated the evolution of the stellar mass function and the star formation rate as a function of stellar mass at 1<z<3, when the stellar mass density in the univrese rapidly increased, in order to study how the stellar mass growth of galaxies proceeded and how it depends on environment.Our results sugget that more massive star-forming galaxies at that time should halt their star formation more immediately and they evolve into passive galaxies. We also found that the environment mainly affects the fraction of star-forming galaxies in massive galaxy population at z~1 and does not affect the star formation rate of star-forming galaxies, and that massive passive galaxies already exist in a protocluster selected by the overdensity of Lyman alpha emitters at z=2.4.
