Masaki-ryū

The Chain That Chose Not to Cut

Masaki-ryū is an Edo-period school of chain and pole weapons founded by the Ōgaki retainer Masaki Toshimitsu, best remembered for the manriki-gusari, the short weighted chain he devised so that a guard could stop an armed attacker without drawing blood at a gate where bloodshed would defile the post.

The gatekeeper's problem

Masaki-ryū (正木流) is a school of Japanese weapon arts founded in the eighteenth century by Masaki Toshimitsu (正木俊光, 1689–1776), a retainer of the Ōgaki domain in Mino province. Toshimitsu is best remembered for the manriki-gusari (万力鎖), a short chain weighted at both ends. Tradition within the school connects the weapon to guard duty: a sentry at a gate needed a way to stop an armed attacker without cutting him down, both because killing at the post would defile it and because not every intruder deserved death. The weighted chain, which entangles, strikes and restrains, answered that need.

A synthesis of many teachers

Toshimitsu's own transmission documents, in which he signs himself Masaki Tarōdayū Toshimitsu, record a long apprenticeship across several traditions of Japan: sword training in the Kotōda line of Ittō-ryū, naginata under teachers of the Sen'i-ryū, and further study that he combined with spear methods and throwing techniques into a system he also called Henri-ryū. The school as it settled came to cover the manriki-gusari, the kusarigama chain-and-sickle, and the naginata, with the chain arts becoming its public signature. He died in 1776 at the age of eighty-eight and was buried in Ōgaki.

To stop an attacker without shedding blood: the weighted chain as a weapon of protection rather than execution.

The school after its founder

The Masaki tradition remained rooted in Ōgaki through the Edo period and was carried into the modern era by an unbroken teacher line. Its chain methods influenced and intertwined with other chain-weapon traditions, and the school continues to be demonstrated at classical martial arts gatherings in Japan today, where the manriki-gusari retains the founder's original framing: a weapon of arrest and protection rather than of killing.
