Understanding galaxy evolution is one of the big subjects in modern astronomy. Galaxy clusters and superclusters, which sit on the top of the hierarchy of structure formation in the universe, are valuable objects to witness various types of galaxies and environments and study how the properties of galaxies change with their surroundings. Submm galaxies (SMGs) are holding hints to reveal the mystery of star formation history in the early universe. In this talk, I will introduce the study of galaxy evolution in the galaxy clusters with the large-scale structure environment in the SA22 field. From this study, we checked the `web feeding model,’ which is that more linked (with their environment) galaxy clusters have less quenched population by investigating the correlation between properties of confirmed galaxy clusters and the large-scale structure environment. Second, I will present the newly found submm galaxies(SMGs) with JCMT SCUBA-2, star-forming populations having the key to revealing the hidden star formation in the universe, in the JWST Time Domain Field near the north ecliptic pole. I also introduce the preliminary image of the JWST for these submm galaxies.
