Simultaneous Color Wide-field Infrared Multi-object Spectrograph, SWIMS, is one of the first generation instruments for the University of Tokyo Atacama Observatory (TAO) 6.5m Telescope now under construction. A dichroic mirror being inserted in the collimated beam, it is capable of two-color simultaneous imaging with FoV of 9!6 phi or R similar to 1000 multi-object spectroscopy at 0.9-2.5 mu m wavelength range in one shot, and enables us to carry out efficient NIR imaging/spectroscopic survey of objects such as distant galaxies and young stellar objects. All the major components have been fabricated and we will start integration and laboratory cool-down test in the summer of 2014. After the engineering and initial science observations at the Subaru telescope, SWIMS will be transported to TAO telescope and see the first light in 2018.
