Hi. It looks like a nice find. It looks like a light touring bike. Consider just polishing and waxing the original paint as it seems to be in a very good condition!

Components tells me this bike was mid level model from late 70s or early 80s. its very nice all the parts are made from aluminum as it will clean up nicely and also suggests it's not a low-end bike. You can try to find out exact year of production by checking out the serial number (stamped on the seat tube as show on your photos). It was very common to mix Japanese and other components with each other by that time, especially on bikes sold by European brands.

I'm sure you will enjoy this bike big time! Again, really nice find!
