  "Keiko Fukuda is the granddaughter of Professor Jigoro Kano's first jujitsu instructor. She began studying the art at Professor Kano's request at age 21 and since that time has taught in Australia,Canada, the Philippines, the U.S. and, of course, the Kodokan where she has received all her promotions (...) In the Kodokan, sometimes we would sit around the mat with Professor Kano and just talk and ask questions so we would know what each other was thinking"
