Japan Karate Do Ryobu Kai

Japan Karate-Do Ryobu-Kai (JKR) is an international karate organization under the leadership of Yasuhiro (Takehiro) Konishi, 10th Dan, son of the organization's founder Yasuhiro Konishi. It has branches in more than 20 countries under the guidance of Kiyoshi Yamazaki, 8th Dan, International Director and Chief Instructor.

The style of karate taught by the JKR is Shindo Jinen Ryu, which was established by Yasuhiro Konishi, who studied under and alongside Gichin Funakoshi, Chojun Miyagi, Kenwa Mabuni, and Choki Motobu. Konishi also trained extensively under the founder of Aikido, Morihei Ueshiba, and JKR's lineage dates back to the 16th century traditions of Takenouchi-ryū Jujitsu. Japan Karate-Do Ryobu-Kai is the sole governing body for Shindo Jinen Ryu, and it is the only major karate organization that has never experienced an internal schism.

Training within Japan Karate-Do Ryobu-Kai stresses traditional Japanese values of discipline, consistent attendance, etiquette, and hard work. Shindo Jinen Ryu incorporates elements of karate, aikido, jujitsu, and kendo in its curriculum, and also emphasizes both philosophy and education.
