Itabashi-ryū Bojutsu This subsumed art focused on the bō, or long staff. It featured 5 kata of bō vs. bō and 8 kata of bō vs. sword. Natsubara-ryū Yawara This subsumed art focused on grappling techniques in a variety of circumstances: standing, kneeling, from behind, etc. The school was divided into 6 sets with 63 kata. Natsubara-ryū seems to be no longer extant. In addition to the bojutsu and yawara, Masaoka's book also makes mention of other techniques, such as torinawa (rope tying) and jōjutsu (short staff). Footnotes Lineage from Hayashizaki Jinsuke to Gotō Magobei is taken from Mitani, p. 25–26. Ikeda gives the pronunciation for Masaoka's name, 壹實, as "Katsutane," although it is often romanized as "Kazumi." "Ikkan" was Masaoka's nickname, derived from another pronunciation of the characters in his name. Notes References Ko-ryū bujutsu Japanese martial arts Japanese swordsmanship Iaido
