XMASS, the Kamioka Dark Matter direct detection experiment with an eye to future multi pur- pose detectors, is planning to improve its Dark Matter sensitivity by increasing the amount of liquid xenon in its inner detector volume from the current 832kg to 5 metric tons. Challenges identified with the current detector informed the design of this upgrade. In this presentation, we present the new detector design and discuss how it addresses these challenges. In particular we discuss how new photomultipliers with their non-flat photocathode layout is expected to improve fiducialization.
