William K. S. Chow
July 3, 1914 - September 21, 1987

William K. S. Chow (who was also known as William K. S. Chow Hoon) was born in Honolulu, Hawaii on July 3, 1914. He became a student of Professor James Mitose (1916-1981) around 1942 at the Nuuanu Y.M.C.A., and eventually became one of his principal assistants. The other was Thomas S. H. Young, from whom it is reported that Chow received his black belt certificate. Other students under Mitose included Jiro Nakamura, Paul Yamaguchi, Bobby Lowe, and Arthur Keawe. Mitose initially called his art "Kempo Jiu-Jitsu". He later used the term "Kenpo Jiu-Jitsu".

Mitose left Honolulu around 1949. It is believed that he went to the Big Island. He later moved to California. In 1953, Mitose published a book entitled, "What Is Self-Defense (Kempo Jiu-Jitsu)". The book was written in 1947. Many photographs of Chow appear in the book.

Chow continued the class at the Nuuanu Y.M.C.A., but called his art "Kenpo Karate" to distinguish it from Mitose's. Students under Chow included Edmund Parker, Adriano Emperado, Joe Emperado, Manny Delacruz, Ralph Castro, Masaichi Oshiro, Solomon Kupahu, and Karate researcher Bruce Haines. Ed Parker is credited with spreading Kenpo Karate on the mainland. Chow's group also trained with Mitose's former students.

Chow's brother, John Chow Hoon, was a student at the Danzan-Ryu JuJutsu dojo of Henry Seishiro Okazaki.

With a career in Kenpo that spanned 45 years, Chow influenced many Kenpo and Karate students and teachers in Hawaii. He passed away in Honolulu on September 21, 1987.
