It's an upper entry level model, mid-1980s,based on the Shimano Z-series shift levers. The level is confirmed by the presence of a rear derailleur with a claw mount. Maruishi started adding the embossing to the fork crown and stay caps circa 1984, so it's still possible that this is a Maruishi, despite the lack of embossing. The serial number will confirm this and provide the year of manufacture.It's almost certainly from somewhere in the region of Eastern Asia or Oceania based on the lighting system mounted on the right fork blade. I'm not sure that it's a touring bicycle, as opposed to one of those dressed up urban bicycles that were popular in the Japanese market, as during this period Maruishi did offer true grand touring modes in America, with triple chaintrings and cantilever brakes. It's upsetting that the owner couldn't even be bothered to mount the chain for the photograph.
