In the Bugei Ryūha Daijiten (武芸流派大事典), the name of this school is also rendered as Jikishin-ryū-kage-ryū (直心柳影流) .
[2][3] It is usually claimed that Satake Kanryūsai was an exponent of Kashima Shinden Jikishinkage-ryū (鹿島神傳直心影流) and Yanagikage-ryū (柳影流).
[4][5] However it is believed by some that Ryūgō-ryū (柳剛流) was instead the main influence of Jikishinkage-ryū naginatajutsu,[6] as Ryūgō-ryū was famous for using very long shinai (120 - 183 cm in length) as well as attacks to the lower legs, a technique which Jikishinkage-ryū naginatajutsu itself became famous for.
Additionally, the way the naginata is held in Jikishinkage-ryū naginatajutsu appears to resemble that of a sword rather than a heavy pole weapon.
In addition, there are five secret naginata gokui-waza (極意技) and four kata forming the reiken-shihō-kiri (霊剣四方切).
