In 1946, Yutaka Yoneyama established Yoneyama Company, which initially produced fishing nets and wooden drifts. In 1957, the company shifted to the production of golf, tennis and badminton products.

In 1961, the first "Yoneyama" badminton racket came out. Two years later, Yoneyama became a manufacturer of international brand badminton products.

In 1969, Yoneyama launched the world's first aluminum badminton racket - #700. Today, more than 80% of the world's athletes use Yonex badminton rackets.

In 1973, Yoneyama Company entered the field of tennis racket production, diversifying the company's products.

In 1978, the company's new "YY" LOGO was launched, consisting of blue and green, and it quickly became well-known in the badminton and tennis circles. A year later, the company and trademark were changed to Yonex.

In 1980, the company launched the world's first ultra-light badminton racket --- Carbonex 8. In the same year, it won the All England Badminton Open.

In 1982, Yonex launched the surprising R series of tennis rackets. The R-1 was the world's first square tennis racket, and the ultra-light R-7 tennis racket won France and Wimbledon. After using a range of lightweight materials to build rackets, Yonex began similar efforts in golf club manufacturing, using graphite.
