Ueshiba studied several martial arts during his early life, and was renowned for his physical strength during his youth. During his sojourn in Tokyo he studied Kitō-ryū jujutsu under Takisaburo Tobari, and briefly enrolled in a school teaching Shinkage-ryū. His training in Gotō-ha Yagyū-ryu under Masakatsu Nakai started in 1903 and continued until 1908, though was sporadic due to his military service, yet he was granted a Menkyo Kaiden (certificate of "Total Transmission") in 1908. In 1901 he received some instruction from Tozawa Tokusaburōin in Tenjin Shin'yō-ryū jujutsu and he studied judo with Kiyoichi Takagi in Tanabe in 1911, after his father had a dojo built on the family compound to encourage his son's training. In 1907, after his return from the war, he was also presented with a certificate of enlightenment ("shingon inkyo") by his childhood teacher Mitsujo Fujimoto.
