The young Ueshiba met Takeda Sōkaku, the founder of Daitō-ryū Aiki-jūjutsu, at the Hisada Inn in Engaru, in March 1915. Ueshiba was deeply impressed with Takeda's martial art, and despite being on an important mission for his village at the time, abandoned his journey to spend the next month studying with Takeda. He requested formal instruction and began studying Takeda's style of jūjutsu in earnest, going so far as to construct a dojo at his home and inviting his new teacher to be a permanent house guest. He received a "kyōju dairi" certificate, a teaching license, for the system from Takeda in 1922, when Takeda visited him in Ayabe. Takeda also gave him a Yagyū Shinkage-ryū sword transmission scroll. Ueshiba then became a representative of Daitō-ryū, toured with Takeda as a teaching assistant and taught the system to others. The relationship between Ueshiba and Takeda was a complicated one. Ueshiba was an extremely dedicated student, dutifully attending to his teacher's needs and displaying great respect. However, Takeda overshadowed him throughout his early martial arts career, and Ueshiba's own students recorded the need to address what they referred to as "the Takeda problem".
