AbstractWe present our continuous efforts over the last decade - since the launch of AKARI - to unveil the environmental impacts on dust properties of galaxies in the local and distant universe by making full use of the AKARI 'all-sky' and 'pointed' observations. We first introduce our new result on the environmental effects on the dust temperature (T(sub dust)) of local star-forming galaxies. By performing stacking analysis of the AKARI FIS all-sky map (at the positions of SDSS star-forming galaxies in different environments), we find that T(sub dust) of galaxies increases with increasing environmental density, supporting a cold dust stripping scenario in high-density environments. We also present the results from our systematic, wide-field MIR 'pointed' observations of distant clusters with AKARI/IRC, in combination with our Subaru H alpha observing campaign. Taking advantage of the wide-field coverage of AKARI (and Subaru), we revealed that dust-obscured galaxies are most frequently triggered at the periphery of distant clusters. The coincidence of the environment of dusty galaxies and that of galaxy color transition suggests a strong link between dusty galaxies and the process of environmental quenching during the course of cluster-scale assembly.
