Shinkage Ryu Kiriai Kudensyo no koto
Sekisyusai put in order the oral teachings of Kamiizumi Isenokami, systematized them, and set them down as gShinkage Ryu Kiriai Kudensho no kotoh. He gave this text to his grandchild, Yagyu Hyogonosuke Toshotoshi, in 1605. The Shinkage Ryu Kiriai Kudensho no koto lays out the concepts of heiho (martial arts) and the art of swordsmanship received from Kamiizumi Isenokami.
It shows the concept of the heiho( martial arts) and complete the art of fencing received from Kamiizumi Isenokami.
Sekisyusai was given certificate of complete mastery in April 1565 and was named the legitimate second headmaster. In May of 1566, he was then given the catalogue,hKagemokurokuh consisting of 4 scrolls; Enpi, Sangaku, Kuka, and Nanatachi.
Motsujimishudan Kudensho
Yagyu Sekishusai served Matsunaga Hisahide, who was defeated by Oda Nobunaga. Seeing that the Ashikaga shogunate was destroyed, Sekishusai retired from worldly affairs and devoted himself to studying heiho at Yagyu Village. Twenty one years later, he was asked to demonstrate Shinkage Ryu with his fifth son, Munenori, in the presence of Tokugawa Ieyasu. Ieyasu admired the performance, and became a believer in the school. The Tokugawa clan adopted it as its official school of martial arts when Sekishusai was 66 and Munenori was 24 years old. After that, Sekishusai devoted himself to training his grandchild, Hyougonosuke Toshitoshi. Toshitoshi had a natural talent and succeeded Sekishusai as the third headmaster.

In August of 1604 when he finished writing gMotsujimishudan Kudenshoh ( Having No taste and No Mind For Fighting), Sekishusai appointed Toshitoshi as his successor. Sekishusai added three more important items to the Motsujimishudan Kudensho before the actual transmission of the headmastership took place in June of 1605. At that time, Sekisyusai gave the Motujimisyudan Kudensyo to Toshitoshi along with two other transmission scrolls, and Toshitoshi was appointed the third headmaster. Sekishusai was 77 and Toshitoshi was 28 years old.

Owari gondainagon Tokugawa Yoshinao (the first head of the Owari Tokugawa domain) was named the fourth headmaster of Shinkage Ryu in 1620. At that time the third headmaster, Yagyu Hyogonosuke Toshitoshi, presented him with gShiju fujashoh along with the other catalogues of techniques and oral texts.
In Shiju fujasho, Toshitoshi explains armoured style heiho (using low stances), which the founder, Kamiizumi Isenokami, and the second headmaster, Yagyu Sekisyusai, used, and adds his own development of a new concept for unarmored combat in an upright posture, gtsuttattaru-mi kempoh.
The founder said that heiho must revitalize or reinvent itself continuously to meet the changing times, and Toshitoshi did just that, developing new concepts for the new times. This was a major development in the history of Japanese swordsmanship. At the time Toshitoshi served the Owari domain as a master of heiho, distant from the practitioners of the Edo Yagyu line, so this new foundation of combat remained characteristic of the Owari Yagyu.

Shinkage Ryu Heiho Mokuroku (Renya kudensho)
The fifth headmaster, Yagyu Renya Toshikane, wrote the gShinkage Ryu Heiho Mokurokuh as an oral text when he was 12 or 13 years old. He briefly summarizes the concepts of the founder of the ryu, Kamiizumi Isenokami, and the second headmaster, Yagyu Sekishusai, and writes comments on each item in the four transmission scrolls of Shinkage Ryu. He discusses the technique and theory of each in terms of the goldh theory of the first and second headmasters and in terms of the gcurrenth theory of his father, Toshitoshi.
Renya never showed this text to other people and sealed it up. He passed it down to his nephew, the eighth headmaster, after writing on the cover that the person who broke his seal would be blinded by Marishiten (a Buddhist deity) in punishment. In accordance with his strong beliefs, the eleventh headmaster, Yagyu Toshiharu, opened the scroll, and it has been giving light to successive headmasters since then.
