Koryū jūjutsu techniques are recorded in the formal kata that belong to individual ryūha. These kata form the central pillars of an art. This is true of Sōsuishi-ryū. The kata are practised strictly in order to ensure the principles are retained and understood. Their applications are then practised in more informal ways – which cater to the self-defence needs faced by our society today.
Jūjutsu practice therefore consists of kata, goshin-jutsu (self-defence) technique and randori (free-practice). This includes defences against a range of weapons and scenarios.
