This is aJapanese instrument box, Koyanagi Seisakasho Engineering Co. with no key. I think the Japanese lettering translate to " Instrument Box Sky" The dove tail empty box shows normal wear, inside looks to be cedar. The hardware looks to be metal over brass. Inside has 4 screw holes and another key hole shape. There is a metal piece in one corner. Also, a crack in the bottom. Probably had another piece attached to the bottom. One foot cover is missing.
