This is a very old item. Furthermore, since the phonograph itself is no longer available, no checks have been performed, including functionality. The genre is likely Japanese kayokyoku (popular songs) or rōkyoku (narrative singing), but it's unclear. As shown in the photos, it has been stored for a long time in a plastic case. The box was in an indoor storage unit, and I've had it exposed to air for the past few years. If you are interested, and if you like it, please purchase it soon while I can still handle the shipping procedures.
