In 1957, Haruo came to the United States and settled in Loomis, California. At that time, he was a first degree brown belt. In 1959, he started a Judo club for Auburn Parks & Recreation, and in 1962 he began teaching Judo at Aerojet in Sacramento.
In 1965, Haruo went to the Sacramento Judo Club to train under Ben Campbell, who was team captain for the first U.S. Olympic Judo team at the 1964 Tokyo Olympics.
In 1971, Campbell Sensei moved to Colorado and passed the title of head instructor of the Sacramento Judo Club to Makimoto Sensei. Makimoto Sensei served as the head instructor at the Sacramento Judo Club for 25 years until his departure in 1992.
Three months later, he opened the Okubo Judo Club. Over the years, the Okubo Judo Club formed affiliations with the Sacramento Asian Police Officers Association (APOA) and the Boys and Girls Club of Greater Sacramento.
Makimoto Sensei was also teaching a judo program at Sacramento High School in their Visual and Performing Arts Center. He taught at the high school from 1999 until the school closed in 2003.
Makimoto Sensei has produced hundreds of Judo champions throughout the years.
