Direct dark matter searches are promising techniques to identify the nature of dark matter particles. The directional information is a distinctive directional property of the dark matter distribution against the cosmic background. The NEWSdm project is a unique experiment among several directional detection projects because of its solid-state detector. The expected signal of WIMP-induced nuclear recoil in such a detector is submicron scale. The high-resolution nuclear emulsion and the special readout method were developed for such extremely short tracks. Technologies for background identification and large-scale analysis are developing toward several kg scale experiment at Gran Sasso underground laboratory in the coming years
