One of the first products Nippon Kogaku produced in its early years were binoculars. Even today Nikon produces excellent binoculars, field scopes, rifle scopes and a variety of spotting scopes for wild life enthusiasts and sports(wo)men. A comprehensive view on Nikon products can be found at the site of the Dutch Nikon binocular collector Hans Braakhuis.
One of the very first and popular binocular was and still is the little 6 x 30 binocular, pictured below. There are several versions known; this one was build during the American occupation of Japan after World War II, 'documented' by the engraving 'made in occupied japan'.
