Hayato Sumino - Ambassador

Hayato Sumino

Born in 1995, Hayato Sumino won the Grand Prix of the Special Class of the PTNA Piano Competition while he was a graduate student at the University of Tokyo in 2018. This was the start of his full-fledged musical career.

Currently, in addition to performing concerts in Japan and abroad, he also writes, arranges, and performs his own music under the name of “Cateen” on YouTube, with over 1,000,000 subscribers and 100 million views (as of June 2022). His unique style, a fusion of classical techniques, arrangements, and improvisational skills, has been well received by many fans.


Since 2021, he has been a CASIO electronic musical instrument ambassador and Steinway artist.  While building a solid position in classical music, he is attracting attention as a truly new type of pianist who carefully focuses on all music that beyond genres.
