We present the ability of weak lensing surveys to locate massive clusters. We use both analytic models of dark matter halos and mock weak lensing surveys generated from a large cosmological N-body simulation. We find that, for a weak lensing survey with a galaxy number density of ng=30 arcmin-2 with a mean redshift z=1, the mean number of galaxy clusters which are expected to be identified is N(S/N>4)=7 per 1 deg2. Weak lensing surveys thus provide a reasonably efficient way to search for massive clusters. We also describe our project on the weak lensing cluster survey exploiting Suprime-Cam (the wide-field prime focus camera on the 8m Subaru telescope), called Suprime-33 and present current status. We also present results from its pilot survey in the Suprime-Cam 2.1 deg2 field.
