Nippon Gakki Co. Ltd. (currently Yamaha Corporation) was established in 1887 as a piano and reed organ manufacturer by Torakusu Yamaha in Hamamatsu, Shizuoka prefecture and was incorporated on October 12, 1897. The company's origins as a musical instrument manufacturer are still reflected today in the group's logo—a trio of interlocking tuning forks.

After World War II, company president Genichi Kawakami repurposed the remains of the company's war-time production machinery and the company's expertise in metallurgica technologies to the manufacture of motorcycles. The YA-1 (AKA Akatombo, the "Red Dragonfly"), of which 125 were built in the first year of production (1954), was named in honour of the founder.

In 1955, the success of the YA-1 resulted in the founding of Yamaha Motor Co., Ltd., splitting the motorcycle division from the company. Also, in 1954 the Yamaha Music School was founded.

Yamaha has grown to become the world's largest manufacturer of musical instruments (including pianos, "silent" pianos, drums, guitars, brass instruments, woodwinds, violins, violas, celli, and vibraphones), as well as a leading manufacturer of semiconductors, audio/visual, computer related products, sporting goods, home appliances, specialty metals and industrial robots.

Yamaha Corporation is also widely known for their music teaching programme that began in the 1950s. Yamaha electronics have proven to be successful, popular and respected products. For example, the Yamaha YPG-625 was awarded "Keyboard of the Year" and "Product of the Year" in 2007 from The Music and Sound Retailer magazine.

To continue growing in the 21st century, the Yamaha Group will make a concerted effort to become a truly global enterprise that fulfills its corporate mission of contributing to enriching the quality of life of people worldwide.
