About
San Mateo JYO (Japanese Youth Organization) is a non-profit, recreational organization where kids play youth basketball and other team sports. The program centers on basketball league play as the primary activity for more than 200 boys and girls in the greater San Mateo area in grades 1st through 8th.
• Ages: 6–13 years old
San Mateo JYO is a 100% volunteer organization, and every family is expected to hold a volunteer position over the course of the season and/or their tenure within JYO. The organization’s mission states that it is focused on building community through youth basketball. It is not a competitive level basketball club or AAU team. The program’s core values are listed as teamwork, sportsmanship, discipline, fun, and equal play. San Mateo JYO is part of the broader Bay Area organization NYBA (Nikkei Youth Basketball Association), which governs basketball league rules and play for youth starting in the 4th grade, along with participating organizations San Francisco Associates, San Francisco Taisho, San Jose CYS, Tri City, and Palo Alto (PAYS). The JYO organization has been around since post World War II, was started by the Japanese American Gardeners Association, and originally offered baseball as the sport of choice before making basketball its primary focus.
