About Yagyu Seigo-ryu Battojutsu
Yagyu Seigo-ryu Battojutsu is a sword-drawing school that the Nihon Kobudo Shinkokai leads as Yagyu Seigo-ryu Batto. It derives from the Seigo-ryu family, which the Nipponica encyclopedia describes as an early modern jujutsu school founded by Mizuhaya. According to Nipponica, the second holder of Seigo-ryu became in 1644 jujutsu instructor of the Owari domain and taught jujutsu together with iai in Edo.

A 2024 study in a Japanese specialist budo journal states that Seigo-ryu was originally a school focused on jujutsu and iai was only a part of it. According to the study, in the late Edo period an assistant of the Owari Yagyu family from the Nagaoka family modified the Shinkage-ryu training system and incorporated into it the modified Seigo-ryu iai. The koryu.com guide names Nagaoka Toreie Fusashige as founder of the school and places its origin around 1690 to 1700. We have not found any other year of origin in the sources. Around 1930, according to the same study, the 20th holder of Shinkage-ryu from the Yagyu family created a new Shinkage-ryu iai based on the Seigo-ryu iai. The study adds that the Seigo-ryu iai is still passed on in most groups that practice Shinkage-ryu. Today the school is, according to the Nihon Kobudo Shinkokai, led by the 14th holder from the Yagyu family, who is also the 22nd holder of Yagyu Shinkage-ryu. The koryu.com guide names as representative the 13th holder, Yagyu Nobuharu Toshimichi.
History
According to the Nipponica encyclopedia, the parent Seigo-ryu is an early modern jujutsu school whose founder was Mizuhaya. According to one tradition that Nipponica reports, he was a native of Kyoto, served Toyotomi Hideyoshi, and after his death withdrew to Settsu province, where he received jujutsu instruction from a mountain monk of Koyasan. According to Nipponica, the second holder of the school became in 1644 jujutsu instructor of the Owari domain with a stipend of 150 koku, and his descendants kept this office afterwards. In Edo he opened a dojo and taught jujutsu together with iai. A 2024 study in a Japanese specialist budo journal states that Seigo-ryu was originally a school focused on jujutsu and iai was only a part of it, as documents of the Kajiwara family attest. According to the study, in the late Edo period an assistant of the Owari Yagyu family from the Nagaoka family modified the Shinkage-ryu training system and also incorporated into it the modified Seigo-ryu iai. The koryu.com guide names Nagaoka Toreie Fusashige as founder of Yagyu Seigo-ryu and places its origin around 1690 to 1700. Around 1930, according to the same study, the 20th holder of Shinkage-ryu from the Yagyu family created a new Shinkage-ryu iai based on the Seigo-ryu iai. The dojo that teaches the school in Yokohama gives a lineage of fourteen generations from Mizuhaya to the present holder.
How it differs
The 2024 study states that the Seigo-ryu iai is still passed on in most groups that practice Shinkage-ryu, and regards this as a success of the attempt to combine swordsmanship and drawing. The Nihon Kobudo Shinkokai lists Yagyu Seigo-ryu Batto and Yagyu Shinkage-ryu as two separate listings with the same representative. The Nihon Kobudo Kyokai has no Seigo-ryu among its members and lists only Yagyu Shinkage-ryu. According to Japanese Wikipedia, the parent Seigo-ryu transmits, besides drawing, also jujutsu, capture techniques and rope tying.
Technique
A 2025 study in a Japanese specialist budo journal compares four generations of Seigo-ryu iai documents, from the Kajiwara family to the 20th Shinkage-ryu holder's modification. In the oldest version the rear toe turns 90 degrees sideways in the first set of seven forms, but in later versions this vanishes and the cut often ends in a sitting posture. The study describes this posture as follows: from seiza both big toes are set upright, the right leg is raised and one sits on the heel, unlike kneeling on one knee. The author hypothesizes that the change of seat was meant to allow an instant transition between standing and sitting.
Training
According to the 2025 study, many iai techniques start from a sitting posture, and the one used in Seigo-ryu is faster when rising than seiza and other ways of sitting. The Yokohama dojo states that it trains drawing seated and standing by repeating forms and holds no matches.
Today
The Nihon Kobudo Shinkokai names as representative the 14th holder from the Yagyu family, with a contact address in Gifu. The koryu.com guide names the 13th holder, Yagyu Nobuharu Toshimichi, and teaching in Nagoya, Tokyo and Osaka. We have not found the school among the cultural properties of Gifu Prefecture.
Did you know
According to the Nipponica encyclopedia, the name Seigo-ryu comes from a saying of Laozi that the softest can overcome the hardest. Nipponica also reports a tradition that the name comes from the monk from whom the founder received jujutsu. According to the same source, the school was strongest in drawn-sword fighting, nukimi.
