Masa Kamaguchi was born in 1966 in Wakkanai City, the northernmost city in Hokkaido, Japan. Masa was inspired to take up the electric bass at age 14 after listening to the records of Jaco Pastorius. In 1985 he moved to Tokyo to attend the Hosei University where he studied engineering but also took up the acoustic bass, studying privately with Yoshio Ikeda, himself a former student of Gary Peacock. In 1990, Masa moved to Boston to attend Berklee College of Music, and proceeded to study with drummer Joe Hunt. While based in Boston, Kamaguchi was in demand to play with many of the area's great musicians, including Geoge Gazone, Bert Sieger, Hal Crook, Herb Pomeroy and Frank Carberg. During this time in Boston, Masa also 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 lumininaries as Frank Kimbrough, Sonny Simmons, Ben Monder, David Murray, Toots Thielmans, Tony Malaby, Charles Gale and many others. His recording credits include dates with Frank Kimbrough, Paul Motion, Ron Horton, Dave Douglas, Sonny Simmons, Tony Malaby, John O'allager, Russ Lossing, Billy Mintz and many others.
in 2006, Masa moved to Barcelona, while he maintains strong connections with NY musicians. He also started to play with European musicians, such as Albert Bover, Perico Sambeat, Albert Sanz and Sara Serpa.
In January 2010, for Jamboree's 50-year anniversary, he played for the Jamboree All Star group and also the Fresh Sound All Star Group.
An acutely intuitive player, Masa brings an individual sound and fresh perspective to the acoustic bass. His rich warm tone and modern style define his individuality. Kamaguchi is a versatile player, at home with a truly wide range of musical influences, that translate into his brilliant concept.
