Yasuhiro Konishi Sensei believed that if you walk a morally correct path in this life, then you are naturally following the divine way. If you train in karate in a natural way and master your body, you will expand your knowledge and experience, and establish a solid foundation for naturally living a morally correct life. On the recommendation of Morihei Ueshiba (the founder of Aikido), Konishi Sensei came to name the system Shindo Jinen-Ryu Karate-Jutsu (“godly, natural style, complete empty-handed way”).
In September, 1924, Hironishi Ohtsuka, the founder of the Wado-Ryu style of karate, and Gichin Funakoshi, the founder of Shotokan karate, came to the kendo training hall at Keio University. They approached Konishi Sensei with a letter of introduction from Professor Kasuya of Keio University. Mr. Funakoshi asked if it would be possible to use the training hall to practice Ryukyu Kempo To-te jutsu. With Konishi Sensei’s help, Funakoshi established a To-te practice club at Keio University (the first university karate club in Japan). Konishi Sensei, Funakoshi Sensei and Ohtsuka Sensei were the principal instructors. Konishi Sensei continued to instruct a curriculum consisting of kendo, jujitsu, and western boxing at the Ryobu-Kan.
Because of Konishi Sensei’s open-mindedness, many well-known budoka visited Ryobu-Kan during his era, exchanging techniques. Among them were: Kenwa Mabuni (founder of Shito-Ryu Karate), Chojun Miyagi (founder of Goju-Ryu Karate), and Choki Motobu. These three masters influenced Konishi Sensei in various ways and made definitive contributions to Konishi Sensei’s emerging style.
