Manzo Iwata was born in Tokyo, Japan, to a family that owned the Iwata-en Tea Company. He began the study of Shito-ryu karate at the age of 10. In junior high school, he also studied judo and kendo. He studied aikido with Ueshiba Morihei, the founder of aikido and a good friend of his grandfather. Iwata enrolled at Toyo University in 1941 and began training in karate directly under Grandmaster Kenwa Mabuni,^[2] the founder of Shito-ryu karate. After beginning training in Kobudo Bujutsu or staff, Iwata was advised by Mabuni to study Jojutsu, or short staff, under Seiko Fujita. In 1943, Iwata received a Jojutsu Shihan diploma from Fujita.
