Found a Japanese game diskette for use in the Nintendo Famicom external disk drive unit. I could only find one disk in a clear carrying case. The game is called ZANAC and from the pic's looks like a aircraft shoot-up game. Also at another thrift today I found 4 game cartridges for the Super Famicom. I'm still looking for a power supply for the Super Famicom console I got from this same thrift last year.
