Kenpo Kai is a traditional form of Japanese Marshal Art.

The name essentially translates to "way of the gathered fists". Though it takes its inspiration from the martial arts of the Shaolin, Kenpo Kai was developed within the Ishizaka family in Japan. A Shaolin monk, in order to avoid the constant burglaries his family was suffering, taught the "Shaolin Kung Fu" to his family members. This art was handed down inside the Chian family and named "Chian Quan" (boxing of the Chian family).

During the Tokugawa period, the Chian family took in a Japanese traveler named Tawada Ishizaka, who was an expert in Kashima Shinto Ryu (the art gathering the Samurai's fighting arts). Ishizaka remained with the Chian family for 20 years, and while a member of their household he learned the art of Shaolin Fist, which he took with him to his homeland. Upon returning to Japan, he codified his knowledge, creating the art that would be handed down in the Ishizaka family, the "Ishizaka Ha Kenpo" (boxing of the Ishizaka family).

In 1967, Kazuo Ishizaka and Sotoki Ishizaka, members of the Ishizaka family, traveled to Shanghai in order to recover old forms and techniques lost with time. They contacted Hou Rou Chian, who has inherited his family art. After two years of training with Hou Rou Chian, Kazuo and Sotoki returned to Japan. They recovered the lost forms and techniques, but felt it was not fair to go on calling their art Ishizaka Ha Kenpo and therefore, they decide to name it "Kenpo Kai". In 1970, Kazuo Ishizaka and Chiaki Ohashi made an in-depth study of the Chinese and Japanese martial arts, joining the inheritance of both cultures together and taking the teachings of the Bushido code.

In August 2004, the first official Kenpo Kai World Championship was organized in the Japanese city of Hamamatsu.
