Nippon Gakki Co., Ltd was born in 1897, 10 years after its founder Torakusu Yamaha had built his first organ. The company's products consisted of organs and upright / grand pianos until 1954, when manufacturing of motorcycles began. The lineup started expanding with bathtubs, wind instruments, sport equipment, furniture and just about everything else imaginable.

Audio products weren't left behind though, with a stylized tuning fork logo even on the motorcycles.* After producing electronic organs, PA equipment and home stereo systems, Yamaha released their first mass-produced keyboard synthesizers, the SY-1 and SY-2, in 1976. In the late 70s the SYs were followed by the CS line, and in the 80s the company had huge success with the DX series, especially the DX7. During the last decade they - like most other big synth manufacturers - have concentrated on virtual acoustic modeling and analog synthesis emulation.
The company bought most of the Korg stock just before they hit gold with the M1 workstation.
