About Tatsumi-ryu Heiho
Tatsumi-ryu Heiho is an old Japanese school whose main axes are, per Nihon Kobudo Kyokai, iai and swordsmanship. It was founded by Tatsumi Sankyo, a warrior from Iyo Province of the Ashikaga period according to Nihon Kobudo Kyokai, who attained enlightenment after praying at a shrine. The city of Chiba places its origin by tradition in the Eisho years (1504–1521), Daijisen Plus at the start of the Sengoku period. In the Edo period the school was, according to Nihon Kobudo Kyokai, the core of the training of samurai of the Sakura domain of the Hotta family. Daijisen Plus states that the domain handed it down as a school not to be taught outside it, and that a side branch in the Nakatsu domain has died out. Nihon Kobudo Kyokai adds that Fukuzawa Yukichi studied in this branch. Besides iai and swordsmanship the school includes, according to Nihon Kobudo Kyokai, jujutsu, the spear, the staff, the short staff, the naginata, rope binding, archery, scouting, ceremonial customs and group combat. By the same source the forms are plain and are called zen in motion. Since 1978 the school has been an intangible cultural property of Chiba Prefecture. Nihon Kobudo Kyokai, Nihon Kobudo Shinkokai and koryu.com give Kato Hiroshi as the 22nd holder, and the city of Chiba notes, as of March 2026, the further recognition of another holder from the Kato family.

Nihon Kobudo Kyokai states that the founder Tatsumi Sankyo was a warrior from Iyo Province of the Ashikaga period who studied the martial arts from youth, attained enlightenment after praying at a shrine and founded the school. The city of Chiba places its origin by tradition in the Eisho years (1504–1521), Daijisen Plus at the start of the Sengoku period. The guide koryu.com gives the Eisho years with an incorrect year. In the Edo period the school was, according to Nihon Kobudo Kyokai, the core of the training of samurai of the Sakura domain of the Hotta family. Daijisen Plus states that the school split in the Edo period and the main line developed under the Hotta family, first in Uzen and after the family's move in Sakura, as a school not to be taught outside the domain. According to the same dictionary a side branch in the Nakatsu domain has died out. Nihon Kobudo Kyokai states that Nakatsu had a branch of the school in which Fukuzawa Yukichi studied. According to Nihon Kobudo Kyokai, fifteen scrolls of the school's writings survive today together with old documents. The city of Chiba states that after the Meiji Restoration the school also entered Tokyo police training.

Training
English Wikipedia states that in paired forms the spear, naginata and staffs always lose to the sword and are therefore practised so that the swordsman can defeat them. Nihon Kobudo Kyokai, koryu.com and Daijisen Plus do not state this rule. The city of Chiba stresses the practical, plain character of the school, recalling the martial traditions of the Sengoku period.
