Shishikan is a Modern Martial Art system using fast closing of space, and close fighting techniques. The system incorporates joint locks, control and immobilization techniques, and pressure points to aid in the techniques. No high kicks are used in Shishikan - kicks are primarily directed at the legs. Techniques are extensively based on Master Pereira's experience in Ryu Kyu Kempo, Modern Arnis, Small Circle Ju Jutsu, Kyusho Jutsu, Kobujutsu, Nindo Goshin Jujutsu, and Nindo Gendai Taijutsu. Shishikan incorporates various elements of the above mentioned martial arts and is a no nonsense approach to self-defense.
