A search for dark matter using an underground single-phase liquid xenon detector was conducted at the Kamioka Observatory in Japan, particularly for Weakly Interacting Massive Particles (WIMPs). We have used 705.9 live days of data in a fiducial volume containing $97\text{kg}$ of liquid xenon at the center of the detector. The event rate in the fiducial volume after the data reduction was $(4.2\pm 0.2)\times {10}^{-3}{\text{day}}^{-1}{\text{kg}}^{-1}\mathrm{ke}{V}_{\mathrm{ee}}^{-1}$ at $5\mathrm{ke}{V}_{\mathrm{ee}}$, with a signal efficiency of 20%. All the remaining events are consistent with our background evaluation, mostly of the “mis-reconstructed events” originated from $^{210}$Pb in the copper plates lining the detector's inner surface. The obtained upper limit on a spin-independent WIMP-nucleon cross section was $2.2\times {10}^{-44}{\text{cm}}^2$ for a WIMP mass of $60{\text{GeV/c}}^2$ at the 90% confidence level, which was the most stringent limit among results from single-phase liquid xenon detectors.
