Instructor Aarian Imada leads the classes, for children 4 to 12 years old, from 6:30 to 7:30 p.m. Fridays at Trinity Dance Studio, 1045 Sperry Ave., Ste. I.
Imada, 23, has a black belt through the United States Judo Federation and has competed in several national events since taking up the martial art as a child in San Jose.
Judo emphasizes discipline, respect and a tradition in which students learn from their opponents in practice and competition, according to Imada, a 2007 graduate of Patterson High School.
The monthly cost for one session each week is $50.
