The Yokosuka K5Y was a two-seat unequal-span biplane trainer (Allied code name: "Willow") that served in the Imperial Japanese Navy during the World War II. Due to its bright orange paint scheme (applied to all Japanese military trainers for visibility), it earned the nickname "aka-tombo", or "red dragonfly", after a type of insect common throughout Japan. The aircraft was based on the Yokosuka Navy Type 91 Intermidiate Trainer, but stability problems led to a redesign by Kawanishi in 1933. It entered service in 1934 as Navy Type 93 Intermidiate Trainer K5Y1 with fixed tail-skid landing gear, and remained in use throughout the war. Floatplane types K5Y2 and K5Y3 were also produced. A total of 5,770 examples were made by eight different manufacturers. These aircraft were the mainstay of Imperial Japanese Navy Air Service's flight training, and as intermediate trainers, they were capable of performing demanding aerobatic maneuvers.   (info from Wikipedia)
