Tablehooters summary: bad smelling toy keyboard with nice LCD animations, rhythms & wonderful demos

I'm surprised that nobody realized that the high hat, snare, ride symbol and cowbell are Casio CTK-150 drum samples. The clap and kick drum are something else.
I've also seen Kawasaki versions of this keyboard on ebay. There's also an unbranded 25 keys variant, which likely shares the same CPU, but with only 25 keys instead of 32 keys.
