What is "hozan-ryu"

or Hōzan-ryū is a koryu sogo bujutsu or complete Japanese martial art.

Founded by Tsutsumi Hōzan (Tsutsumi Yamashiro no kami Hōzan), the date of its founding is debatable. The most likely time for its founding would have been in the late 14th or early 15th century. Since Tsutsumi Hōzan was the 12th disciple of the priest Jion, it is safe to assume that the sword style of Tsutsumi Hōzan-ryū would have been based upon Jion’s Nen Ryu. Hōzan was also adept with the jitte and at jujutsu, originally referred to as yoroi kumi (grappling in armor). Traditionally, Tsutsumi Hōzan-ryū also included the yari (spear), bo (staff), torinawa or hojojutsu (tying techniques), and kusarigama. Some also suggest the manriki or manriki-gusari (chain) and chigiriki and jo (staff and chain) may have been included in the system.
