First Carrier Division
Captain Ichiro Ono assumed command on 15 November 1934 and "Ryūjō" became the flagship of Rear Admiral Hideho Wada's First Carrier Division. The following month the ship was chosen to evaluate dive-bombing tactics using six Nakajima E4N2-C Type 90 reconnaissance aircraft, six Yokosuka B3Y1 Type 92 torpedo bombers, and a dozen A2N1 Type 90 fighters. The reconnaissance aircraft proved to be unsuitable after several months' testing. "Ryūjō" participated in the Combined Fleet Maneuvers of 1935 where she was attached to the IJN Fourth Fleet. The fleet was caught in a typhoon on 25 September and the ship was moderately damaged. "Ryūjō" arrived at Kure on 11 October 1935 for repairs, modifications, and a refit that lasted until 31 May 1936. On 31 October Ono was relieved by Captain Shun'ichi Kira.
