Master Yasuhiro Konishi was born in 1893 in Takamatsu, Kagawa, Japan. At the age of 6 he was introduced to the practice of the ju-jutsu school Muso-ryu. At the age of 13 he began studying kendo and then studied the ju-jutsu school Takeushi-ryu. This school of ju-jutsu is characterized by the use of striking technics.
During his university studies, Yasuhiro Konishi teaches kendo. He studies the art of Okinawa te with another student named Tsuneshige Aragaki a native of this island.
In 1923, he taught kendo and ju-jutsu in his own dojo called the Ryubukan. The following year he received a visit from Master Gichin Funakoshi and Master Hironoshi Ohtsuka looking for a place to teach their art of karate. Master Konishi welcomes their demands.
In 1927 and 1928 Master Kenwa Mabuni lives in the house of master Yasuhiro Konishi. Then, during the 1930s, other masters of karate from Okinawa came to visit with Master Konishi such as Master Chojun Miyagi and master Choki Motobu .
In 1935, Yasuhiro Konishi studied the art of aiki-budo under the tutelage of Master Morihei Ueshiba.
Master Yasuhiro Konishi is a renaissance man in the art of Japanese karate. Under the guidance and with the encouragement of Master Ueshiba, he created the kata tai sabaki incorporating the principles of aiki with those of karate. Then, in collaboration with both Master Mabuni and Master Ueshiba, he created the kata Seiryu that incorporates the principles of aikido, ju-jitsu and karate.
At that time, all the Masters of Karate gave a name to their schools. Master Konishi named his school Shindo Jinen Ryu Karate Jutsu, which can be translated as « divine and natural style of the empty hand » on the recommendation of Master Morihei Ueshiba.
After World War II, Master Konishi devoted his life to teaching karate. He died in 1983 and it is his son, Takehiro Konishi, that succeeded him as head of the Japan Karate-do Ryobu-kai.
