My first guitar was a second-hand Kiso-Suzuki. Not much is known, other than that it was a company from Japan that use to do Martin replicas until they were faced with lawsuits.
My research led me to believe that it is made of ash wood, manufactured in 1979 and has a 2 5/8 inch saddle (only 1 store on eBay has them). The neck has a wonderful feel, most probably solid rosewood and the guitar is very light (nothing else is solid). Surprisingly with a truss rod for calibration.
Did some modifications since it only had 1 strap pin which I replaced with a Schaller strap lock and fitted a second on the neck.
