An Osprey of Japan Ground Self-Defense Force (JGSDF) was attending to the Japan-US joint exercise "Keen Sword 25" and was performing a patient evacuation excercise at Camp Yonaguni. When the V-22 took off, hovered and moving forward to ascend at 11:38 LT, the pilot noticed unexpected descent which forced the takeoff to be aborted. Just after the touch down, the Osprey bounced and begun roll oscillation left and right. The left engine nacelle was contacted with the ground and damaged. There were no reported injuries among 16 occupants of crew and passenger troops of Japan and US forces.
JGSDF grounded all V-22s (until the finish of the accident investigation).
On 13th November, a news source reported that the cause of the accident was the pilot error, and on 14th, JGSDF released a summary of the accident report. The copilot forgot to activate the "interim power switch" which temporarily boosts power for takeoff, and the PIC as pilot flying did not check it. Piloting of PIC at touch down and on the bouncing was also inappropriate. The delay in the schedule and the last minute addition of one more passenger were a psychological burden and became contributing factors.
