In 1990, Masa moved to Boston to attend Berklee and proceeded to study with and drummer Joe Hunt. While based in Boston, Kamaguchi was in demand by many of the area's great musicians, including tenor saxophonist George Garzone, and pianists Frank Carlberg and Bert Seager. Also during this time in Boston, Masa toured Europe and Scandinavia, on several occasions. In 1994 Masa moved to New York City where he is much in demand by many groups, performing with such luminaries as , pianist Roberta Piket, the modern acoustic quartet NAM, Ben Monder, Billy Mintz, Chris Cheek, and Tony Malaby.
