Aria was formed in Japan in 1956 by Shiro Arai as "Arai & Co., Inc
They began retailing acoustic guitars in 1960, although the company did not start manufacturing their own until 1964. Aria arranged for Matsumoku, the musical instrument maker, to build the guitars for them under contract. Arai and Matsumoku started building acoustic guitars in 1964, and then electric guitars in 1966, using Arai, Aria, Aria Diamond, Diamond, and much less frequently, Arita brand names. The Aria brandname was changed to Aria Pro II in late 1975, though this has been used mostly (but not exclusively) for electric guitars and basses. All guitars were made in Japan until 1988, when production of less expensive models (Magna MAB/MAC and Integra IGB series) was switched to Korea. In the mid-1990s a few models (including the Fender Stratocaster-inspired Fullerton series guitars and the Steve Bailey 6-string fretless signature bass) were made in the United States.
Guitar designer and audio engineer, Ronnie Parker started his career with Aria in 1985 when they were located in the City of Industry, California
