Chief Instructor Shihan Sensei Robert Ishimaru began his martial arts training in 1973.   He has studied multiple martial arts, including Chinese Win Chung.  With a strong Karate foundation in Shotokan he holds an advanced traditional karate shihan level black belt mastering the entire 26 kata syllabus.  He believes that the power of Shotokan , kicks, punches and stances are important for balance and transference of power.

Shihan most importantly values his Instructor Certification in All Japan Karate Federation  Renbukai Karate do and holds a (JKF) Shihan grade. By traveling back and forth to Japan he understands traditional curriculum more succinctly.  With many years now teaching Shito Ryu kata  he gives his students the added benefit of the elegance and details of the many facets of  Kenwa Mabuni’s kata legacy.  He also enjoys the speed and footwork shito ryu enhances.   For a more realistic kumite experience Shihan Ishimaru embraces BOGU kumite aspect of Renbukai and embraces the legacy of the JKF founders in Japan from 1954. Born and raised in Japan he is honored to keep his culture alive in the USA by teaching traditional Japanese karate.  Traditional karate offers no shortcut to success.

Sensei Bettina Ishimaru began her training in 1984.  For over 20 years she trained in Shotokan karate and obtained a 5th degree.  While continuing to pursue excellence in the arts of karate she obtained a (JKF) 3rd Degree Black belt from the All Japan Karate Federation Renbukai in 2016.    She strives to compliment her curriculum with Shito Ryu based kata syllabus for all of her students. She teaches fundamentals with an emphasis on “shite kata ichiro“or required forms firstly.  Fitness is also a large component in her classes. Times drills for speed makes every karate ka achieve better conditioning which makes them perform at a higher level.   Ultimately, she feels that competition is healthy for the practitioner to test his/her true knowledge, as the increased practice towards towards it increases overall skill.  She loves teaching youth and teens as she believes that their potential is unlimited.   Learning from students changes your teaching as every student is unique and their movements are adaptation to traditional karate is also unique.  As a special supplement to her training Bettina studied the art of chin na or joint locking and tendon seizing. Every karate te waza (hand technique) works with positive ROM while every chin na technique works with the inverse –so they are complementary and a perfect supplement to understanding true kata success.          She teaches up to 8 classes weekly.  The more she trains the more she can offer.   Unlike other sports—It is the journey that counts.
