Looks like an NSF player.  Has a cartridge slot, maybe for utilizing sound expansion chips?

Google Translate says UglyJoe is correct.

Yeah, it does look pretty sweet.  If the FC cart-slot is for utilizing the expansion audio chips like I suspect it is, then that's really quite a brilliant feature.
