Keiko Fukuda is a judo teacher in San Francisco who recently attained a high rank in the art, the 9th dan. In the documentary she explains how for 30 years she was kept at an artificially low ranking because she was female. Today she has rank and respect and is still teaching at age 96. Flying Carp Productions is making a documentary film about her life. They still need donations to help finish the film!
