FUJIGEN started production in 1960 under the name Fuji Gengakki Seizō (富士弦楽器製造, lit.

In the 1970s, Fuji started making OEM guitars for companies such as Hoshino Gakki (Ibanez), 1970's UK importers, Arbiter, Charles Summerfield Ltd (Ibanez, CSL, Cimar & Sumbro) and J.T Coppock (Antoria) Kanda Shokai (Greco guitars) and Yamaha.

Fuji obtained a CNC router in mid 1981 for making guitar parts and also began to manufacture their own pickups starting in late 1981.

In 1989, Fuji Gengakki Seizō re-branded, officially adopting the name FUJIGEN.

FUJIGEN still manufactures OEM guitars for companies like Ibanez and Epiphone but in much smaller quantities than in the past.
