Mr. Davey is one of only a relatively small number of Americans and Europeans that can truthfully be called a kodansha. In Japan, this title is usually reserved for martial arts teachers ranked sixth-degree black belt and above . . . I have watched Mr. Davey interact with high-ranking martial arts masters from Japan on many occasions. He is treated as a respected peer by these instructors, many of whom are notably difficult to impress.
— Walter Todd Sensei (1927-1999) studied martial arts in Japan starting in the late 1940s. An early pioneer in the US, Todd Sensei held an eighth-degree black belt in judo, an eighth-degree in karate-do, and a sixth-degree in aikido, all from organizations in Japan.
