Nonprofit for over 30 years, San Diego Peninsula Shotokan Karate in Point Loma's Liberty Station traces a direct lineage to Master Gichin Funakoshi through Shotokan Karate of America's 1955 founding. The curriculum strips away commercial belt inflation—SKA recognizes only three ranks (white, brown, and black) with a 5th-dan ceiling—and trains kata, kumite, and self-defense under the same body-awareness principles that underpin aerial and tumbling disciplines at San Diego Circus Center. The head instructor, a 4th-degree black belt training with SKA since 1995, competed on the U.S. team in France in 2014 and at SKA's 60th-anniversary tournament in 2016. The high-impact sparring and repetitive striking patterns inherent to Shotokan can stress knees and hips over time, making the sport-specific rehabilitation at Spine & Sport Physical Therapy a natural complement for long-term practitioners. SKA's national infrastructure gives members access to regional and international training events, including the oldest continuously run karate tournament in the United States.
