Shotokan (松濤館 Shōtōkan) is a style of karate, developed from various martial arts by Gichin Funakoshi (1868–1957) and his son Gigo (Yoshitaka) Funakoshi (1906–1945). Gichin was born in Okinawa and is widely credited with popularizing "karate do" through a series of public demonstrations, and by promoting the development of university karate clubs, including those at Keio, Waseda, Hitotsubashi (Shodai), Takushoku, Chuo, Gakushuin, and Hosei.
Shotokan was the name of the first official dojo built by Gichin Funakoshi, in 1936 at Mejiro, and destroyed in 1945 as a result of an allied bombing. Shoto (松濤 Shōtō), meaning "pine-waves" (the movement of pine needles when the wind blows through them), was Funakoshi's pen name, which he used in his poetic and philosophical writings and messages to his students. The Japanese kan (館 kan) means "house" or "hall". In honor of their sensei, Funakoshi's students created a sign reading shōtō-kan, which they placed above the entrance of the hall where Funakoshi taught. Gichin Funakoshi never gave his system a name, just calling it karate.
Focus on Kata:
Funakoshi always believed kata was the secret to becoming skilled in karate. When he moved to Japan, he brought 16 kata with him: five pinan and three naihanchi, along with kushanku dai, kushanku sho, seisan, patsai, wanshu, chinto, jutte and jion. He made students practice the pinan and naihanchi forms for at least three years before he allowed them to progress to the more advanced kata. The repetitious training paid off, though, because his students developed the most precise, exact karate taught anywhere.
