This is one of the rarer Japan made Leica copies from the 1950s, made just after Yashica took over Nicca.   Obviously trying to emulate the new leica M3 it includes such M3 features as Lever film wind, Oversize viewfinder window, Part opening back for easier film loading and Protective bumpers around the viewfinder.  With the original f1.8 Yashinon lens.  Serviced and fully working this would be a gem in any 35mm rangefinder collection.
