KIZUNA, a Japanese company that is still relatively unknown in Europe, has established itself as one of the most popular string manufacturers in Asia in recent years. Responsible is Mr. Abe Hideo, who founded KIZUNA in 2013 and stands for the production and distribution of badminton strings and equipment "Made in Japan". As a long-time badminton trainer and former national coach, Mr. Hideo has made it his goal to develop good badminton strings that support the game of amateur players. Many recreational badminton players lack physical condition and technique. And this is exactly where KIZUNA comes in. Good badminton strings should make you feel like a better player.
