The Yokosuka MXY-7 Ohka was a purpose-built, rocket-powered human-guided kamikaze attack-aircraft deployed by Japan against Allied ships in the Pacific Ocean theater towards the end of World War II. Although extremely fast, the Ohka had a very short range, so it had to be carried into action as a parasite aircraft by a much larger bomber, which was itself vulnerable to carrier-borne fighters. In action during the Battle of Okinawa in 1945, Ohkas succeeded in sinking or damaging some escort-vessels and transport ships, but never sank any major warships. The Japanese developed improved versions in an attempt to overcome the aircraft's shortcomings, but they came too late for deployment.

The cherry blossom, or sakura, is the flower of trees in Prunus subgenus Cerasus. "Sakura" usually refers to flowers of ornamental cherry trees, such as cultivars of Prunus serrulata, not trees grown for their fruit. Cherry blossoms have been described as having a vanilla-like smell, which is mainly attributed to coumarin.
