Hayato Sumino was a semi-finalist at the 2021 International Chopin Piano Competition in Warsaw. 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 1.2 million subscribers and 150 million views (and counting)! Sumino’s debut at the prestigious Suntory Hall in Tokyo sold out on the day of release. His unique style, a fusion of classical techniques, arrangements, and improvisational skills, has been well received by fans around the world. A CASIO electronic musical instrument ambassador and Steinway artist, he is a truly new type of pianist that pushes the boundaries of classical music.
