I'd even say you can get a hold of it pretty fast, even if you'll be surprised at the efforts you make to try to play 'correctly' with it, but it's very rejoicing! It's not a guitar for beginners, who will find it hard to play with! Nevertheless, you can get used to it pretty fast if you have a good playing level. It's unforgiving with approximate fingerings due to the very narrow neck with an almost flat radius. The neck has a somewhat disturbing profile when you are used to more recent folk guitars. In the Japanese guitar system, the model reference number (180 in this case) is generally linked to the catalog price in dollars, so this guitar was probably sold for about $150 in stores back then, which would've corresponded to a mid-range instrument. The nitrocellulose lacquer finish is very simple, in the D18 style, but it's nice, especially with age. Pretty vintage open gear tuners that do their job without complaints. Bone nut and bridge that, I think, are not the original ones. The top is solid spruce, the bottom and sides seem to be of solid wood, too, probably mahogany or something that looks like it. No clue about when it was born, but it certainly has seen the best part of 40 years or so.

Mine has the red-orange Nippon Gakki tag, so it's manufactured in Japan. The Yamaha FG-180 is a dreadnought-type Folk guitar with a slim mahogany neck with 'boat' profile, almost flat rosewood fingerboard.
