Sorry to be a pedant but I'd say mid to late 70s. 
 
 
On the whole, early 70s copies (with the exception of replica-level stuff like Tokai) weren't too accurate & wouldn't have copied the bullet truss adjuster seen here. Early Fujigen copies, for example, usually have a small white plastic truss rod cover & a Gibson-type nut. You'd also expect to find a 3-piece neck on an early 70s Fujigen.
There's nowhere near enough to tell from the pic, but if this is a Fujigen it will be '76-'77 or perhaps later.
