Traditional martial arts

About Our Style:  Shibukawa Ichi-Ryu 
The Shibukawa Ichi-ryu Jujutsu (澁川一流柔術) was founded by Shuto Kuranoshin Mitsutoki in the last days of Tokugawa Shogunate (1840's). Shuto Kuranoshin learned Shibukawa-ryu (渋川流), and Namba Ippo-ryu (難波一甫流) from his master, Miyazaki Giemon. Moreover, he practiced Asayama Ichiden-ryu (浅山一伝流) at another place. He then founded Shibukawa Ichi-ryu Jujutsu as a result of his studies.


Shibukawa Ichi-ryu’s movements can be classified into several groups how to be moved by the opponent, Kutugata that you practice first have 35 movements and it is a basic all of Shibukawa Ichi-ryu’s movements. It is not showy and it is made of simplicity movement to suppress the opponent. We have an another way of practice, Bounuke, Makurabiki and Iji-keiko (like a Judo’s Randori).


One day Kuranoshin fought six Hiroshima domain clansmen to keep his honor in the Hiroshima castle town. But it was not hard for him to beat them off by Shibukawa Ichi-ryu technique. It happened that one Matsuyama domain clansman witnessed this fight and he recommended Matsuyama domain clansman in Tempo 10 (1839). After that Kuranoshin had started to teach Shibukawa Ichi-ryu in Matsuyama, Shikoku.


After the Meiji Restoration, he often came back to Saka village, Aki county in Hiroshima Prefecture where his relatives lived in. And he passed Shibukawa Ichi -ryu on to his aenior disciple in Hiroshima. In 1879, he died at the age of eighty-nine at Matsuyama.


After Shutou Kuranoshin's death, they stopped teaching the art in Matsuyama, Shikoku Prefecture. But in Saka village, in Hiroshima Prefecture, Shibukawa Ichi-ryu Jujutsu became more and more prosperous. The dojo of Tomokichi Miyata was the most active of these schools. Kurumaji Kunimatsu was the most gifted of his students, and he founded his own dojo, teaching Shibukawa Ichi-ryu to his students. He was also a bonesetter and an acupuncturist. Une Shigemi was the most senior among his pupils, and was named successor to Kurumaji Kunimatsu.


Morimoto Kunio is the legitimate representative of Shibukawa Ichi-ryu Jujutsu, and the most senior pupil of Une Shigemi. He was initiated into all the secrets of the school (Menkyo Kaiden). He was appointed as the legitimate successor by his master, Une Shigemi. Morimoto Sensei also served Une Shigemi until his death, and only he and his students were permitted to attend the funeral of Une shigemi Sensei by his family.

Classical Samurai Self-Defense

The Shinwakan Dojo / IMAC offers classes in classical samurai self-defense, or Jujutsu. It is a comprehensive art with both empty-hand and weapons techniques. We are one of the only schools in the Indianapolis area teaching authentic Koryu (classical) Japanese Jujutsu.

What is Classical Jujutsu?
Classical Jujutsu is a form of feudal era samurai close quarter combat. It utilizes empty-hand techniques, and the use of various weapons carried by the samurai. This is distinctly different from modern "jiu-jitsu" forms and mixed martial arts (MMA) grappling.


It is a myth that classical Jujutsu is brutal or dangerous to practice. In reality, the samurai practiced together with members of their domain; their family, friends, children, and co-workers. They did not injure each other during the practice of their martial arts. Doing so would be dishonorable. Classical Jujutsu is a soft art, practiced slowly with maximum relaxation to help develop the core of the body "center", or seika tanden. Most "Jujutsu" the public is familiar with is influenced by modern sport Judo, perhaps mixed with some Karate and other elements. This is not traditional Japanese Jujutsu. Our own teacher, Kunio Morimoto Sensei, often tells us to relax more and always fondly relates how his own teacher, Une Shigemi Sensei's grip was like a grandfather holding the hand of his grandchild.
