We present our survey for optically variable objects such as active galactic nuclei (AGN) and distant supernovae (SNe) with a wide-field optical imager, Suprime-Cam, on the prime focus of the 8.2-m Subaru telescope. By combining with 50-100 ksec exposure X-ray data obtained with XMM-Newton, we confirmed that optical variability is a useful tool for finding AGN and found that it plays a complementary and important role for studying low-luminosity AGN with X-ray observation. We found that a significant fraction of optical-variability-selected AGN are below the X-ray detection limit, which was also shown by studies with HST. The SN sample is used for cosmology and SN studies such as rates, its host galaxy properties, and its progenitors. We also introduce the next-generation wide-field imager, Hyper Suprime-Cam (HSC), installed on the Subaru telescope in 2011 fall, our survey plan and expected results with Subaru/HSC.
