Maywa Denki

The Otamatone (Japanese: オタマトーン, Hepburn: Otamatōn) is an electronic musical synthesizer. Shaped like an eighth note note, the ribbon controller on its stem is what can be used to control the notes being played by it as the sound comes from the Otamatone's "head". It was developed in Japan by the CUBE Works toy company and the Maywa Denki design firm, led by the brothers Masamichi and Novmichi Tosa, and is produced and marketed by Hamee.
