Yonex was founded in 1946 by Minoru Yoneyama, a former producer of wooden floats for fishing nets. Forced out of his industry by plastic floats, Yoneyama vowed to never be forced out of an industry due to technology. After some success introducting aluminium into tennis and badminton racquets, he started looking at introducing graphite into golf clubs. This has set an innovation and "technology forward" culture at Yonex's R&D division, who's tagline is 'far beyond ordinary technology'.
Well known brand ambassadors include Scott Hoch and Phil Mickelson, as well as Colin Montgomerie and the teenage sensation Ryo Ishikawa.
