Gyokko-ryū (玉虎流 Gyokkoryū) is a school of kosshijutsu(骨指術) (attacks to muscle and nerve points), shitojutsu (using the thumb and fingers for striking), kenjutsu[citation needed], and bōjutsu. Gyokko-ryū is sometimes referred to as Gyokko Ryū Ninpo from a ninjutsu component it used to contain[citation needed]. According to the 1968 edition of the Bugei Ryuha Daijiten, Masaaki Hatsumi is the current Sōke (head master) of the Ryū which was passed to him by his teacher Takamatsu Toshitsugu. Shoto Tanemura of the Genbukan has menkyo kaiden in this ryu from Takamatsu-den and has founded his own branch of Gyokko-ryu called Gyokko-Ryu Tanemura-ha. He teaches the ryu within the Genbukan organization.

Note about bōjutsu: The bōjutsu that was taught in 2005 in the Bujinkan as part of that year's study of Gyokko Ryu is actually from a branch of Kukishin Ryu. This branch is Shinden Tatara Ryu Bōjutsu. Takamatsu Sensei taught this curriculum in the 1950's at a university. This bōjutsu is in several parts: kamae gata, kihon gata, and shoden, chuden, and okuden kata.

According to the Bujinkan, Cho Gyokko brought the school to Japan from China during the Tang Dynasty and it was handed down from generation to generation. Sakagami Taro Kunishige organized Gyokko Ryū shitojutsu. In the Tenmon period (1532 - 1550), he taught it to Sakyo Isshinsai who created Gyokko Ryū kosshijutsu. Its sister school is the Koto Ryū, also created by him. Both Gyokko Ryū and the aforementioned Koto Ryū were taught by him to Momochi Sandayu, who carried on the traditions within Iga Ryū until the late Tokugawa period (mid 19th Century). Techniques from Gyokko Ryū and Koto Ryū became the foundation for techniques of Togakure Ryū.

The school is roughly divided into three sections: unarmed against unarmed, unarmed against kodachi, and unarmed against sword.
