Japan Karate-Do Ryobu-Kai (JKR) is a professional, international, karate organization founded by Yasuhiro Konishi, and developed by his son, Yasuhiro (Takehiro) Konishi, 10th Dan. JKR branches are located all over the world and are currently under the leadership of Kiyoshi Yamazaki, 9th Dan, who serves as Kaicho (President).
The JKR also has a lineage dating back to the 16th century traditions of Takenouchi Ryu Jujitsu.
Training in the JKR 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. Modern training in Shindo Jinen Ryu karate-do incorporates elements of karate, aikido, jujitsu, and kendo in the formal curriculum, with an emphasis on philosophy and education. The curriculum also emphasizes Zanshin (the ability of an exponent to gain dominance over an opponent through an alert state of mind) and the maintenance of proper physical posture.
The school participating in the Japan Karate-Do Ryobu-Kai demonstration and workshop is Japan Karate-Do Ryobu-Kai, Fabio Rodriquez.
