Today, karate-do is taught all around the world, and though it is often modified and always changing, four distinctive Japanese styles have emerged:
Gōju-ryū
Shitō-ryū
Shotokan
Wadō-ryū
Karate has evolved into a popular and beloved sport. The World Karate Federation (WKF), the largest organisation for karate as a sport, has developed a system of common rules and regulations, and though it is not yet recognized as a permanent Olympic sport, the WKF is recognized by the International Olympic Committee IOC and coordinates with various national Olympic committees. Karate was part of Olympic Games 2021 held in Tokyo, Japan.
