XMASS program is a multi-purpose low-background experiment with large volume of liquid Xe scintillator at Kamioka in Japan. In the current stage, we focus on the the direct detection of dark matter in the form of WIMPs (Weakly Interacting Massive Particles) with 835 kg liquid Xe. Though we started commissining on 2010, we found unexpected background on PMT sealing material. To overcome the background, we conducted refurbishment from 2012 to 2013 and restarted data taking in Autumn of 2013. We present the latest result on data after the refurbishment. We will also present the status of extensive studies for a future XMASS project.
