Shiro Arai founded Arai and Company in 1953 as an importer of classical guitars. In 1960, Arai contracted Guyatone to manufacture guitars. At the time, Guyatone was one of Japan's leading musical instrument manufacturers. However, when exported to the western United States, the drier American climates caused early Guyatone-produced guitars various problems: bindings became unglued, backs split, and necks broke just below the headstock. Guyatone could not meet Arai's production requirements, and in 1964, Arai and Company contracted for musical instrument manufacturing with Matsumoku. Arai addressed these issues early on with Matsumoku's management. The solution was to use wood that had been dried for at least two years, stronger glues with longer clamp times, and one feature that remained throughout Matsumoku's production: the 3-piece maple neck. Besides Matsumoku, Aria had two factories that produced guitars, one of which made classical guitars, and another that made medium-grade and specialty guitars. But the relationship between the two companies was both amicable and symbiotic. Aria focused on sales in both domestic and export markets and provided design development, while Matsumoku devoted its energies to engineering and building guitars and other stringed instruments. Throughout its 22-year business relationship, Aria remained Matsumoku's principal client. Matsumoku often preferred using Aria as its business agent, and many of Matsumoku's contracts were written by Aria with Matsumoku stated or implied as sub-contracted manufacturer. Arai and Company guitars were briefly labeled Arai, but switched to the familiar Aria around 1966. From the 1975 arrival of design engineer Nobuaki Hayashi (currently with Atlansia) onward, however, all Aria guitars were labeled Aria Pro II. Hayashi's pseudonym, "H. Noble", appeared on many of the Aria Pro II instruments he designed. Aria's guitars that followed showed remarkable design innovation and a definitive move away from Gibson and Fender formats. Hayashi is best known as the designer of the Aria Pro II, SB-1000 bass and the Aria Pro II PE-series guitars. Some of these were made with maple bodies, but higher-end models such as the PE1000 with Protomatic pickups and the PE1500 with
DiMarzio pickups, had ash bodies. These ash-bodied guitars were produced only in relatively small numbers for the domestic market; most, however, had maple bodies. Some guitars were produced with the urushi finish and, again, these, in both red and brown urushi lacquer, were produced mostly for the domestic market. The vast majority of these have ash bodies, whereas the export models were made mainly of maple. Matsumoku also manufactured drum kits under the Aria name, initially under licence from Remo, which had identified a gap in the market for low-cost drum kits in the compact 5-piece "rock" configuration as innovated by the Rogers PowerTone range in the early 1970s. ==Epiphone==
