Bojutsu is the art (jutsu) of using a 6ft staff or cudgel (bo). In Okinawa, Bojutsu is the main form of the classical weapons arts (Ryukyu Kobudo), and is the primary long range weapon practiced in Shorinjiryu Karatedo.

The form of Bojutsu practiced in Shorinjiryu is called Shishiryu Bojutsu, which means lion style bojutsu. According to Hanshi Masayuki Kukan Hisataka, Shishiryu Bojutsu is the hereditary art passed down in the Kudaka (Hisataka) family of Okinawa.

Kaiso Kori Hisataka learnt Shishiryu Bojutsu from a young age from his father, an uncle and his grandfather. He supplemented this learning with instruction from Ufuchiku (Police Chief) Sanda Kanagusuku, a leading weapons exponent in Okinawa in the early 20th century. Further consolidation of Bojutsu came from studies with experts in Taiwan and China during the 1930’s.

The primary weapon of Bojutsu is a 6ft (182cm) staff (rokushaku bo) made of Oak or similar hard wood. Within Shishiryu Bojutsu a straight (non-tapered) Bo is preferred due to its greater strength.

Kaiso Kori Hisataka taught that an all round Bojutsu training regime should focus on the rokushaku bo, but should make occasional use of other forms, including the 4 ft staff (yonshaku bo or jo) as well as the boat oar (kai or eku) and perhaps the spear.

The main Bo katas practiced within Shorinjiryu Karatedo including Gorin bo Bo and Shishiryu no Bo. Some schools of Shorinjiryu also teach other Bo kata, including Tokumine no Bo, a form emphasised by Master Chotoku Kyan, one of the principal karate instructors of Kaiso Kori Hisataka.
