About Nami ryu

Traditionally martial arts in Japan are passed on from teacher to student by direct transmission. The origins of Nami ryu are in Yanagi ryu Aiki Bugei, the martial traditions of the Yoshida clan of the Satsuma region of Kyushu, Japan.

Yoshida Kotaro

Yoshida Kotaro was thus a gifted martial artist who was well known in pre- and postwar Japan. He was an associate of many of the most important people in Japanese martial traditions of the 20th century, both old and new.

Yoshida Kotaro was involved with Takeda Sokaku, who brought classical Samurai martial traditions into the 20th century. He was also directly instrumental in Ueshibia Morihei, the founder of Aikido, meeting and training with Takeda Sensei. This knowledge that Ueshiba gained from Takeda Sokaku was the foundation of his development of Aikido as a major modern martial art.

Yoshida KenjiYoshida Kenji

We have no known record of Yoshida Sensei passing on his family art to anyone in Japan. The only person that we know of who had knowledge of these family traditions, however, was his son Yoshida Kenji, who came to the United States prior to the Second World War.

Don Angier Sensei

Yoshida Kenji Sensei, having no relatives in the United States and no contact with Japan, taught and passed his art on to Don Angier. Don Angier Sensei has dedicated his life to the study of Yanagi ryu, which was the family art of the Yoshida clan. Angier Sensei passed away in October, 2014.

James Williams Sensei was a student of Angier Sensei for many years.

James also studied Daito ryu Roppokai with Okamoto Seigo Sensei.

James teaches Close Quarters Combat to police and military both foreign and domestic. The method used, “The System of Strategy,” is based on those skills developed and cultivated by ancient warriors.

Kuroda Tetsuzan Sensei

Kuroda Tetsuzan Sensei of the Shinbukan Kuroda Dojo, is the Soke (familial inheritor) of several ancient Samurai military disciplines. Kuroda sensei inherited this knowledge through his family line and is the headmaster of the Kuroda family martial legacy. The arts that he has inherited include:
  • Komagawa Kaishin ryu kenjitsu –  Shishin Takuma ryu jujitsu
  • Tamiya ryu iaijitsu –  Tsubaki Kotengu ryu bojitsu
  •  Seigyoku Oguri-ryū Sakkatsujitsu

Kuroda Sensei began his training at the age of 5 and was trained by both his father and his grandfather Kuroda Yasuji.

Komagawa Kaishin ryu kenjutsu was founded by Komagawa Tarouzaemon-kunikichi in the 16th century.

Kaishin is composed of two words, kai and shin. Kai means change and shin means mind or spirit. Kaishin means changed mind or spirit. The Kuroda family styles of jujutsu, kenjutsu, and iaijutsu were founded 450 years ago.
