I would like to take this opportunity to introduce Mr. H. E. Davey. Mr. Davey has achieved a deep understanding of traditional Japanese culture and martial arts . . . Mr. H. E. Davey, a friend for whom I have the greatest fondness and respect, has been studying and teaching Japanese budo ("martial ways") for many years. For an equally long period, he has also engaged in serious research into the history and lineage of aiki-jujutsu, which is a form of kobudo.
— The late Sato Shizuya Sensei of Tokyo was Chief Director of Japan's Kokusai Budoin HQ and a tenth-degree jujutsu black belt. He trained in Japanese martial arts for over 50 years and traveled the world teaching budo.
