After Telésforo Julve bought the company in 1933, Hoshino Gakki decided in 1935 to make Spanish-style acoustic guitars, at first using the "Ibanez Salvador" brand name, and later simply "Ibanez." and Fuji Gen Gakki guitar factories to manufacture Ibanez guitars, and after the Teisco guitar factory (Teisco String Instrument, Company) once closed down in 1969/1970, Hoshino Gakki used the Fuji Gen Gakki guitar factory to make most Ibanez guitars.In the 1960s, Japanese guitar makers started to mainly copy American guitar designs, and Ibanez-branded copies of Gibson, Fender and Rickenbacker models started to appear. During this period, Ibanez produced guitars under the Mann name to avoid authorities in the United States and Canada.The Hoshino Gakki company began in 1908 as the musical instrument sales division of the Hoshino Shoten, a bookstore chain.The Ibanez brand name dates back to 1929 when Hoshino Gakki began importing Salvador Ibáñez guitars from Spain.In September 1972, Hoshino began a partnership with Elger Guitars to import guitars from Japan. On June 28, 1977, in the Philadelphia Federal District Court, a lawsuit was filed by the Norlin Corporation, the parent company of Gibson Guitars, against Elger/Hoshino U. After the lawsuit, Hoshino Gakki abandoned the strategy of copying "classic" electric guitar designs, having already introduced a plethora of original designs.Hoshino was producing their original Artist models from 1974, introducing a set-neck model in 1975.
Documents lodged with City Hall describe it as a development of a ‘prestige nature’ in terms of its appearance and of the products and services offered.
During the early 1980s, the Fuji Gen guitar factory also produced most of the Roland guitar synthesizers, including the Stratocaster-style Roland G-505, the twin-humbucker Roland G-202 (endorsed by Adrian Belew, Eric Clapton, Dean Brown, Jeff Baxter, Yannis Spathas, Christoforos Krokidis, Steve Howe, Mike Rutherford, Andy Summers, Neal Schon and Steve Hackett) and the Ibanez X-ING IMG-2010.
