Yonex started life in 1946 as a producer of wooden floats for fishing nets. The company was later forced out of this market because of the invention of plastic floats. This led to a commitment by Yoneyama to never again be left behind by technological advancements.
The company began to experiment with graphite shafts for tennis and badminton racquets and found that these would also be useful for golf clubs. Finding a growing market, the Yonex Corporation (as we know it today) was established in Torrance, California in July 1983.
