System armed combat with the use of bo, a 5 foot long stick in Japan and 6 feet in Okinawa. The bojutsu was already being practised by the Japanese feudal warriors, although the systematic bojutsu not developed until the late Kamakura period (1192-1333) or the first Muromachi period (1338-1598),. The Shinto-style katori ryu, founded by Izasha Inenao, is the root from which they are born most other systems. Holding the stick and clasping both hands, bojutsu runs beating, striking, parando, deflecting, tapping and blocking. The position of the hands on the stick determines whether the blow is inflicted by a long distance or short, making the weapon, or bo, and the same bojutsu fit for combat at close range or wide-ranging. Kata (form of exercise) is the only method of training.
