X-ray follow-up observations of optically-selected clusters of galaxies in the Subaru HSC field are presented. To study the ICM properties and cluster scaling relations, we perform systematic analyses of i)optical clusters at low-redshifts using XMM archive data and ii) high-redshift clusters using new XMM data. Our results suggest that the present sample contains a larger fraction of disturbed clusters in comparison with X-ray-selected samples and the redshift evolution of L-T relation is slower than that expected from the self-similar model. Implications of the results are discussed.
