The Yoshukan International Karate association has historical roots that go back over 1,000 years. Martial arts teaching has been passed down from generation to generation for centuries. Complete systems were often taught only to family members and instruction was kept secret and guarded as a precious heirloom.
In recent years, instruction became more public, beginning with the introduction of martial arts training into the Okinawa and Japanese school systems in the late 1800's in fact, the art of karate was first introduced to Japan in 1922, the USA in 1946, and Canada in 1958.

Tsuyoshi Chitose

Dr. Tsuyoshi Chitose, also known as as Chinen Gua in Okinawa, was the founder of Chito Ryu Karate. Born in Kumochi, Naha City, Okinawa-ken (prefecture), on October 18th, 1898 Dr. Chitose created Chito Ryu after spending years studying both Shorin-Ryu and Shorei-Ryu. He became the Supreme Instructor, 10th dan, of Chito-Kai of the All Japan Karate Doh Federation.
Chito Ryu developed from two disciplines, Shuri no Te (now known as Shorin-Ryu) and Naha no Te (now known as Shorei-Ryu). O-Sensei created Chito Ryu by combining the merits of each with his medical knowledge to come up with a more healthy alternative.
O-Sensei was introduced into the secrets of Naha no Te by the respected fifth master Mr. Aragaki Ou at the age of seven. At that time Mr. Gichin Funakoshi a pioneer of Karate-do on the mainland was also in Naha as a student.
At Shuri city O-Sensei studied under such masters as: Mr. Choyu Motobu, Mr. Chotoku Kiyan, Mr. Haragusuku Chiyomu, Mr. Kanryo Higaonna (who also taught Mr. Chojun Miyagusuku, the founder of Goju-Ryu and Mr. Kenwa Mabuni, the founder of Shito-Ryu).
In 1922 O-Sensei went to Tokyo to study medicine, while there he assisted in the opening of Mr. Funakoshi's SHOTO-KAI YOTSUYA dojo. He instructed in kumite and the kata of SEISAN and BASSAI.
After World War II, in March 1946, O-Sensei opened a karate dojo called Yoseikan in Naka Machi, Kikuchi-gun, Kumamoto-ken.
In 1958 O-Sensei attained the the rank of Juudan from ZEN OKINAWA KARATE KOBUDO RENGO KAI (The all Okinawa Karate and Weaponry association).
In 1975 he moved his dojo which was known as the SOHONBU (General headquarters) to Tsuboi, Kumamoto City, where it presently exists.
