Aikido Silicon Valley
Martial Art, Self-Defense, Budo
Located in Sunnyvale, CA since 1998

An effective self-defense does not have to be violent and destructive. The dynamics of Aikido gives us the option of a hard or soft response to an attack, and the calmness of mind to choose appropriately.

Techniques involve blending with the energy of an attack, drawing the attacker out of their area of strength, and redirecting the energy of the attack to a favorable outcome.

Principles of harmony, blending with adversity, and leading a conflict to a positive resolution makes Aikido applicable to physical conflict as well as daily life.

  • Learn skills for self-defense and for the defense of others
  • Improve physical strength and health, confidence, discipline and awareness
  • Continually develop personal character through budo
We are located in Sunnyvale and easily accessible to the greater San Jose area. Classes are taught by Dojo Cho David Yoshinaga Sensei (5th degree black belt), Alice MacAllister Sensei (5th degree black belt), Bill Witt Shihan (8th degree black belt and Master Instructor), and James Ashby Sensei (5th degree black belt).
