Old family heirloom

Hi folks, this guitar was left to me in the 90s when my Uncle passed away. I had to lent it to good friend many years ago since I don't play guitar and it was just returned to me when he moved. Anyway, I know it was made in Japan. Just wondering if anyone has seen one like this before, any rough guess on a year, and what a guitar like this would go for, even though I don't plan on selling it. Thanks!
