## Abstract content

XMASS is a multi-purpose experiment using a single-phase liquid-xenon scintillator detector located underground at Kamioka Observatory in Japan. Thanks to a low-energy threshold and low background, the XMASS detector has a potential to pursue various topics in a field of neutrino physics. For example, XMASS has a possibility to detect galactic supernova neutrinos via coherent elastic neutrino-nucleus scattering. We have also searched for two-neutrino double electron capture on $^{124}$Xe and set the most stringent lower limit on the half-life at $2.1\times 10^{22}$ years at 90% confidence level. In this poster, we will discuss the latest results on neutrino related subjects from XMASS.
