Jikishinkage-ryū Naginatajutsu (直心影流薙刀術) is one of the two classical schools of the naginata, the long Japanese glaive, that lie behind the modern standardised form of the art. It carries the name of the old Jikishinkage-ryū sword tradition, but its surviving history is mostly that of a line of teachers, many of them women, who kept the glaive alive through the late Edo period, the Meiji upheaval and into the twentieth century. Its single most important figure is Sonobe Hideo (園部秀雄, 1870–1963), through whom the school reached the modern age.
A name shared with the sword school
The school's name announces a descent from Jikishinkage-ryū, one of the most important of the classical sword traditions and a recognised ancestor of modern kendō. The naginata line presents itself as a branch of that tradition, carrying the same name and a claim of shared descent. What is harder to establish is an unbroken, documented chain linking the sword school to the glaive line across every generation. The two are transmitted separately, each with its own teachers and its own curriculum, and the older stretch of the naginata line is recorded only thinly. The honest position is that the shared name reflects a genuine tradition of common origin, while the detailed lineage that would prove a continuous link between the swordsmen and the naginata teachers is, in its earliest parts, a matter of tradition rather than independent record.
The whole advantage of the glaive is its reach, and timing rewards mobility over force.
A tradition carried by women
By the late Edo period the naginata had become, more than any other weapon, the martial discipline of women of the samurai class. The long glaive let a smaller person hold off a swordsman at a distance, and it acquired a settled place in the upbringing and household defence of warrior families. The Jikishinkage-ryū naginata line belongs to this world: it was taught and transmitted in large part by women teachers of the late Edo and Meiji periods, at a time when the glaive was passing from a battlefield weapon into a discipline of character and physical training. This is one reason the school's earlier history is less fully documented than that of the great sword schools, whose heads were often domain instructors with official records behind them. A tradition kept largely by women, outside the formal structures of the domains, leaves a fainter paper trail, and a careful account has to admit how much of the early line is recovered from tradition rather than firm record.
Sonobe Hideo
The figure who carries the school into firm history is Sonobe Hideo (園部秀雄, 1870–1963). She is remembered as the foremost transmitter of Jikishinkage-ryū naginatajutsu in the modern era, a teacher of great influence who trained generations of students over a long life. Her career coincided with the spread of the naginata as a subject taught to girls in Japanese schools during the first half of the twentieth century, and she was among the teachers who carried the classical art into that wider movement. Through her the school passed from a classical tradition kept by a handful of households into the institutions of modern Japanese education, and the line of teachers who learned from her carried it on after her death.
The naginata and its method
The art is built around the reach and versatility of the glaive. A curved blade is mounted on a long shaft, and the method uses every part of it: sweeping cuts and thrusts with the bladed end, strikes and blocks with the shod butt (ishizuki), and the constant switching of the leading end that lets a single weapon attack high and low, left and right, in quick succession. Footwork and distance are central, because the naginata's whole advantage is its reach, and a great deal of the training lives in paired forms (kata) in which one side takes the glaive and the other a sword or a second glaive. The result is a complete and demanding weapon method, very different in feel from the sword schools, that rewards mobility and timing over brute force.
Behind the modern naginata
In the twentieth century the Japanese naginata world set about creating a single standardised form of the art that could be taught and practised competitively across the country, much as kendō had been drawn from the older sword schools. The result, established in the mid-1950s under what became the All Japan Naginata Federation (Zen Nihon Naginata Renmei), is the modern discipline usually called atarashii naginata, "new naginata". It drew above all on two classical schools: Tendō-ryū and Jikishinkage-ryū. The standardised forms and much of the modern teaching method descend from these two koryū, and Jikishinkage-ryū's place as one of the two foundations of the modern art is its clearest claim on the wider history of Japanese martial arts. Both classical schools continue to be practised in their own right alongside the modern form they helped to shape.
The school today
Jikishinkage-ryū naginatajutsu survives as a living classical tradition, transmitted through lines descending from Sonobe Hideo and practised both in Japan and, through their students, abroad. It is studied today for its own sake, as one of the few complete classical methods of the glaive, and as part of the wider naginata community that grew out of it. Its history is a useful corrective to the usual picture of the koryū: an old weapon tradition kept alive less by famous swordsmen and domain academies than by a long line of dedicated teachers, many of them women, whose names are only now being given their due.
