Yonex Co., Ltd. (founded 1946) commands a premium position in badminton, tennis, and golf equipment. Its flagship racquets—such as the Nanflare, Astrox (badminton), and EZONE (tennis)—retail for $150–$300+. This price point has attracted sophisticated counterfeiting operations. In response, Yonex introduced serial numbers on shaft cones, cap grommets, or hologram stickers.
