We investigate halo properties and star formation histories of galaxies at z=4-7 based on the large-area data newly obtained by our Subaru/Hyper Suprime-Cam (HSC) survey and the complementary deep images taken from the Hubble Space Telescope (HST) legacy surveys. Combining these unique large-area and deep datasets covering a wide range of luminosity, we develop new samples of Lyman break galaxies (LBGs) at z=4-7 that are significantly larger than the previous clustering studies at z>=4. We derive angular correlation functions of our galaxies, and perform the halo occupation distribution (HOD) modeling that includes a star-formation duty cycle. The dark halo masses and the duty cycles are typically ~10^11 Msun and ~50%, respectively, which are consistent with the previous high-z galaxy study results. With our high precision measurements, we have, for the first time,identified the notable evolution of the stellar-to-halo mass ratio (SHMR) from z=0 to z=4-7 based on galaxy clustering data. Based on these results, we discuss star-formation and feedback processes in high-z galaxies.
