About Our Karate History and Tradition

Training in the Nihon Karate School is conducted in the traditional Japanese method, stressing discipline, consistent attendance, etiquette, and hard work. Karate instruction is life-long and can be continued regardless of age.

Training at Nihon Karate School incorporates elements of Shotokan Karate, Shito Ryu Karate, Aikido, and Jujitsu in the formal curriculum, with an emphasis on philosophy and education.

The purpose of training in karate is to develop the whole human being, physically and mentally. Through long-term, dedicated training, students learns to develop and unite Shin (mind), Gi (technique), and Tai (body) in proper proportions. The end result is awareness of one’s moral obligations and place in society.

What is the Jinen Kai Karate organization?

Nihon Karate School is a member of the Japan Karate-Do Jinen Kai organization that practices Shindo Jinen Ryu Karate-Do.

The Japan Karate-Do Jinen-Kai was founded in 2015. Initially comprised of dojos from Southern California, Arizona and Aruba, it takes on the challenges of building the next generation of martial artists - well-balanced and capable individuals in Shin (Spirit), in Gi (Technique), and in Tai (Body).

The history of the Japan Karate-Do Jinen-Kai is rooted in the foundations of the Shindo Jinen-Ryu style of Karate that was founded by Yasuhiro Konishi (1893-1983) in October 1933. This is an eclectic style incorporating elements of traditional Karate (primarily from the Shotokan and Shito Ryu styles), Aikido and Jujitsu; with emphasis on the founder's philosophy of "Ken Zen Ichinyo," "The Mind and Body are ONE."

While the backbone and foundation of Jinen Kai Karate is Shindo Jinen Ryu, we are focused on taking the best of all backgrounds and infusing the training into something that works for each individual.

What is Shindo Jinen Ryu style?

Shindo Jinen Ryu is the first original style born in mainland Japan. It was founded by Yasuhiro Konishi, and developed by his son, Yasuhiro (Takehiro) Konishi. JKJ branches are located across the United States and are currently under the leadership of Sensei Patrick Martin, Sensei Chad Eagan, and Sensei Dustin Baldis.

The style of karate taught at Nihon Karate School is called Shindo Jinen Ryu. Yasuhiro Konishi learned karate from Gichin Funakoshi, Chojun Miyagi, Kenwa Mabuni, and Choki Motobu. Additionally, Konishi Sensei studied extensively under the founder of Aikido, Morihei Ueshiba.

Inspired to further develop and extend the Shindo Jinen Ryu style, while paying homage to the great masters and their legacy, the Japan Karate-Do Jinen-Kai organization was founded in 2015.
