The Yamaha Corporation (Japanese: ヤマハ株式会社; Romaji: Yamaha Kabushikigaisha) is a Japanese company with a large number of product areas. Sales offerings include motorcycles (Yamaha Motor Corporation), musical instruments, integrated circuits, and home electronics. It was founded by Torakusu Yamaha as Nippon Gakki Co., Ltd. (Japanese: 日本楽器製造株式会社; Romaji: Nippon Gakki Seizou Kabushikigaisha) in Hamamatsu, Shizuoka prefecture. Yamaha acquired Korg in 1989.

Yamaha has produced many of the integrated circuit chips for Sega arcade and console hardware, such as the YM2612 sound chip for the Sega Mega Drive console. Yamaha held the patent for FM synthesis, which was featured in many Yamaha synthesizers and sound chips, while some of their sound chips also featured PCM sampling. In addition, Yamaha also manufactured VDP graphics processors for the Sega Master System and Mega Drive consoles.
