Dark matter search by means of the annual modulation was done using large single-phase liquid-xenon detector, XMASS. With the data from November-2013 to March-2015, model independent analysis showed a weak modulation effect, however, the result can be explained by a fluctuation of the background at the level of 7-17%. If we assume the standard weekly interacting massive particles dark matter, we exclude almost all the allowed region claimed by the DAMA/LIBRA experiment. This is the first extensive search over their allowed region exploiting the annual modulation with high statistics data.
