"In 1905 a school was formally opened to teach kendo instructors and Naito was selected as the senior teacher. At this time the school was known as the Bujutsu Kyoin Yoseijo, but eventually (after a few re-organisations and renames) it would be known to everyone as Busen (Budo Senmon Gakko). It was to this school that Ogawa was dispatched by the Nagoya police department in 1907. Ogawa would spend 3 years studying kendo directly under Naito."

"At the Busen Abbe received instruction from Ogawa Hanshi (genius), the Butokukai Judan (10th Dan) sword master. While at the Busen Kenshiro also enrolled in Mr. Gen Tanabe's philosophy class, at the Kyoto Teikoku University. That early encounter with philosophy would be influential in the formation of his system. While the training was arduous at the Busen, Kenshiro managed to receive his Yondan (4th Dan) rank in Judo, being again the young Judoka to attain it. His sister, Toyoka, decided to take Martial Arts too, enrolling in Mrs. Mitamura's Naginata class. She would dedicate the rest of her life to the practice of the art."

"While still at Kyōto, Hirano later also became an uchi deshi to Ushijima Tatsukuma"
