Jishukan Honbu was developed during the reign of Japanese Emperor Hirohito by Mr. Shuho Sugita; our first Principal and Master. He researched the Martial Arts and combined them with medical science, anatomy, dynamics and psychology. It was formed as an attack-defence Martial Art, and as a rule it is practised without using weapons.

Shuho Sugita was born in Shimozuki Japan and was raised in Yokohama. He inherited his Martial Arts interest from his father and went into training during childhood. Consequently he was recognised as a man of genius with great potential by Master Saito, who was known as one of the great masters of the classical Martial Arts.

Sugita was trained by Master Saito in JuJutsu, Kempo, Hai a Na Wa which was known as the quick rope technique, and JoJutsu the stick art. When he was thirteen years old he was granted an honourable certificate. After that he received his training at the Kodokan Takehashi Dojo, the Shiroken Dojo and the Kitoro Kodokan. Whilst training at these dojos, Sugita came to realise that:

"the essence of the Japanese Martial Art must be formed on the basis of Koryu, or the classical Martial Art, and without practising the Koryu, a man cannot win overall"

Sugita went on a pilgrimage to many places searching for new instructors and new methods. In 1947 he finally initiated the Jishukan Ryu Dojo in Kanazawa Yokohama. Soke (which means Founder or First Master), died in 1983 after a long illness. His later years in Jishukan were not spent in physical instruction but rather in working in the Jishukan Clinic, practising Shiatsu and giving medical care to students when necessary.
