Owari Kan-ryū (尾張貫流) is a school of Japanese spearmanship, sōjutsu, preserved in the old Owari domain and centred on present-day Nagoya. Founded in the seventeenth century by Tsuda Gonnojō, it is best known for the kuda-yari, a spear used together with a short metal tube.
The kuda-yari
The defining feature of the school is the kuda, a hollow metal sleeve held in the forward hand, through which the shaft of the spear slides and turns. The tube steadies the line of the thrust and lets the spear be driven out and recovered quickly, while the spin adds power and control. It is an unusual and distinctive approach to a weapon that most schools handle with the bare hands alone.
Control the line of the spear and the contest is decided before contact.
In the Owari domain
The school was preserved under the patronage of the Owari branch of the Tokugawa house, one of the senior lines of the ruling family, alongside the domain's other martial arts. This domain setting helped the tradition survive, and it has continued to be taught in the Nagoya region into the present day.
Honesty note
The founder and the earliest generations are less fully documented than the modern transmission, which is the firmer part of the record. Owari Kan-ryū is a living koryū, and Ryūpedia describes its securely transmitted present more confidently than the finer details of its origin.
