The XENON series of experiments has been highly successful in pushing the limits of WIMP direct searches for more than a decade. We are currently operating the XENON1T detector, the most sensitive dark matter detector ever built, at Laboratori Nazionali del Gran Sasso (LNGS). The XENON1T experimental setup and infrastructure were designed to allow for a fast upgrade of its central detector, a two-phase xenon Time Projection Chamber (TPC). The XENONnT project, the next phase of the program, will feature a new TPC with an active target of ~6 tonnes of Xenon (4 tonne fiducial) and will implement a series of technological solutions aiming to further suppress the dominant background sources and boost the physics reach of the experiment. In this talk, an update on the status and prospects of the XENONnT phase (especially Japan’s contribution to the experiment) will be presented.
