High-z quasars are believed to reside in massive haloes, which is recently supported by both theoretical and observational aspects. This picture suggests that the quasars should be detected in the galaxy overdensity region, but the previous observations show diverse environments around high-z quasars. However, their targets are limited to bright quasars (M1450<-25), whose photoevaporation effect hinders galaxy formation in their vicinity. Here, we present the Subaru/HSC observations for four low-luminosity quasars (-24
