Superluminous supernovae (SLSNe) are a new class of SNe which are more than 10 times brighter than previously known SNe. In addition, they are especially bright in UV and we can find them even if they appear at very high-redshift. Their progenitors are likely very massive stars and they can be a probe for the high-mass end of the initial-mass function at very high redshifts. I will introduce SLSNe, review the SLSN survey planned in HSC and SPLASH, and show what can be leaned from the surveys in this presentation.
