The final goal of XMASS experiment aims at the direct dark matter, the solar neutrinos from pp and ^7Be and neutrino less double beta decay with ton scale fiducial volume of liquid xenon detector. In the current stage, we focus on the the direct detection of dark matter in the form of WIMPs (Weakly Interacting Massive Particles) via their elastic scattering off Xenon nuclei with 800kg detector at Kamioka in Japan. XMASS 800kg detector will achieve a sensitivity more than two order of magnitude beyond current limits of WIMP-nucleus cross section to reach 10^<-45>cm^2 for the spin independent case. The status of experiment will be review and discussed here.
