Yonex Co., Ltd. (ヨネックス株式会社 Yonekkusu Kabushiki-gaisha) (TYO: 7906) is a Japanese manufacturer of sporting equipment for badminton, golf, and tennis, producing rackets, clubs, shoes, shuttlecocks, tennis balls, and other equipment for those sports.
The company was founded in 1946 by Minoru Yoneyama 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.
In 1957, Yoneyama began to make badminton racquets for other brands. By 1961, the first Yoneyama-branded racquet was introduced, and within another two years an export company was created for the worldwide distribution. After the company began to make aluminum badminton racquets in 1969, it found that the same technology could be applied to the tennis racket which the company introduced in 1971. The company began to experiment with graphite shafts for both types of rackets and found that these would also be useful for golf clubs.
In 1982 Yonex came out with the new oversized tennis racquet in the REX-series with the R-7 and R-10 racquets. At that time Martina Navratilova played with the R-7 and was very successful. One year later, the new series Rexking was developed with the R-22. Navritalova subsequently used the white RQ 180 widebody frame until the early 1990s.
Finding a growing market, the Yonex Corporation (a wholly owned subsidiary) was established in Torrance, California in July 1983. In 1992 Yonex introduced the widebody badminton racket, the "Isometric 500", a racquet that was much less "tear drop"-shaped than previous ones. The more "square" head gave it a much larger striking surface, which provides a larger "sweet spot" to hit the shuttle. It led other manufacturers to follow suit in "square-head" or isometric designs. The parent company was listed on the Tokyo Stock Exchange in 1994. Yonex describes itself as the world leader in golf, tennis and badminton equipment. Yonex provides clothing for national badminton associations around the world, such as the Malaysian Badminton Association, Badminton Scotland, Badminton England, Badminton Ireland, and Badminton Wales. Yonex has also been teaming up with OCBC (Orange County Badminton Club) since 2007 to host the annual U.S. Open Grand Prix Badminton Championships.
Yonex has become the dominant corporate player in badminton. Yonex sponsors the All England Open Badminton Championships and is a partner of the Badminton World Federation which organizes the World Championships. Upwards of 80% of competitive players use their racquets, as it is the preferred choice amongst professionals. Yonex is significant in the tennis and golf industries as well and is a major sponsor of professional athletes in all three sports.
Yonex supplies official materials for the following leagues, athletes, teams, or associations:

Yonex signed a contract with Chinese Taipei Badminton Association (Taiwan) regarding national team jersey sponsorship in 2014. However, Yonex would often send players clothing and shoes to wear a few days before major tournaments, with the shoes unfit for players, as players had blisters and bruises on players' feet from playing.
In May 2016, Yonex was ultra vires to criticize the Taiwan national team players who have violated the dress code. Yonex sent official documents to the Chinese Taipei Badminton Association threatening to sue the Taiwan national team head coaches if the Association could not provide a reasonable answer.
During the period of 2016 Rio Olympics, Yonex provided unfit shoes to non-contract badminton player Tzu-Ying Tai. This forced Tai to wear other shoes made by her personal sponsor brand, Victor, without any logo. And this event caused a controversy due to Chinese Taipei Badminton Association (Taiwan) is going to punish Tai based on Yonex's pressing.  
After Tai's incident outbreak, there are other five "victim" badminton players in the same situation and got punished. For example, Yonex was dissatisfied that badminton player Kuan-Hao Liao used his personal sponsor bat and then Yonex was ultra vires to ask Chinese Taipei Badminton Association (Taiwan) to fine Liao and force him be suspended for six months.
In August 2016, the Chinese Taipei Badminton Association (Taiwan) held a board meeting to resolve the situation. The meeting resulted in 3 key decisions: (i) no punishment will be enforced on the “player”; (ii) to accept the resignation of Chairman Tsai Hung-peng for the controversy; (iii) to remove “Shoes” and “Racquets” from the contract between Yonex. The player’s father commented that he was “very grateful” after hearing this news
