Mission History
On May 24, 1945 took off on a night mission to crash land at Yontan Airfieyld on Okinawa. Aboard were Japanese Army soldiers from the Giretsu Special Attack Unit on a suicide mission to destroy parked American aircraft and cause as much damage as possible on a suicide commando raid.

Between 8:00pm to 10:00pm other Japanese aircraft made a diversionary bombing raid against Okinawa to confuse U.S. defenses. Meanwhile, this Ki-21 made a successful wheels up landing on the runway at Yontan Airfield. While skidding, the left engine nacelle tore off behind the bomber rear and the nose perspex fell off.

After skidding to a halt, approximately eight to ten commandos exited the bomber and began their suicide commando raid destroying nine parked aircraft and damaged twenty-nine others at Yontan Airfield. They also managed to set fire to 70,000 gallons of fuel causing a huge fire that was visible miles away. By dawn, each commando was killed by defending American personnel.

On May 25, 1945 the wreckage of this bomber was photographed where it crash landed on the runway at Yontan Airfield. Afterwards, the U.S. Navy 87th Naval Construction Battalion (87th NCB) "Seabees" personnel used a pair of cranes to lift the bomber and tow it off the runway. Afterwards, American personnel began removing pieces of aluminum from the wreckage as souvenirs. The ultimate fate of this bomber is unknown, likely scrapped or otherwise disappeared.
