I'm  a  jazz pianist, born in Japan and currently residing in Amsterdam, the Netherlands. Before moving to Amsterdam, I had lived in New York for 7 years. No matter where I live, no matter whom I play with, despite the differences of nationalities, cultures and backgrounds, we always find common ground in jazz music - improvisation.
